The sections `Progress`, +`Surprises & Discoveries`, `Decision Log`, and `Outcomes & Retrospective` must +be kept up to date as work proceeds. + +This ExecPlan must be maintained in accordance with `.agent/PLANS.md` from the +repository root. + +## Purpose / Big Picture + +MQT Core needs an OpenQASM frontend that can represent valid OpenQASM 3.1 even +when the QC or JEFF target cannot lower every construct yet. After this work, a +caller can parse OpenQASM 3.1 or supported OpenQASM 2 compatibility syntax into +a verified, typed MLIR module using an experimental `oq3` dialect. A separate +pass lowers the supported part of that module to MQT's QC dialect. This split +makes source-language validity independent of target capability and prevents the +parser from becoming a second, target-specific type checker. + +The current implementation is an architectural demonstrator. It proves the +parser, typed intermediate representation, diagnostics, and initial lowering +boundary, while deliberately leaving the established OpenQASM importer as the +production path. The demonstrator can be observed by running the focused test +binary described below: the tests parse representative 3.1 and 2.0 programs, +verify the generated module, lower supported programs to QC, and distinguish +source errors from target-capability errors. + +The repository-relative scope is the OpenQASM target under +`mlir/include/mlir/Target/OpenQASM` and `mlir/lib/Target/OpenQASM`, the OQ3 +dialect under `mlir/include/mlir/Dialect/OQ3` and `mlir/lib/Dialect/OQ3`, its +focused tests under `mlir/unittests/Target/OpenQASM`, and the directly related +build and documentation files. Existing QC translation code remains a comparison +oracle and must not be replaced until parity is demonstrated. Unrelated changes +and other independently coordinated tasks are outside this plan and must be +preserved. + +## Progress + +- [x] (2026-07-15 10:10Z) Started the implementation from a fresh `origin/main` + while keeping the legacy importer available. +- [x] (2026-07-15 10:35Z) Pinned the OpenQASM 3.1 grammar, generated the C++ + ANTLR parser, isolated the generated code in its own target, and recorded + its provenance and regeneration command. +- [x] (2026-07-15 10:50Z) Added the experimental typed `oq3` dialect, its + source-specific types and operations, verifiers, and OQ3-to-QC pass. +- [x] (2026-07-15 11:05Z) Added the staged frontend, OpenQASM 2 normalization, + include handling, initial semantic checks, control flow, measurements, + gates, modifiers, scalar state, ranges, tests, and conservative + documentation. +- [x] (2026-07-15 11:10Z) Verified 24 focused tests, 224 existing QC translation + tests, and 110 compiler pipeline tests. All passed. Repository lint passed + except for the then-existing unrelated `ty` diagnostic in + `python/mqt/core/plugins/qiskit/estimator.py:235`. +- [x] (2026-07-15 11:25Z) Fetched and analyzed merged PRs #1815 and #1907, + fast-forwarded canonical `main`, re-read `AGENTS.md`, `.agent/PLANS.md`, + and `docs/ai_usage.md`, and rebased the implementation onto commit + `a228a3dc2`. +- [x] (2026-07-15 11:28Z) Resolved the #1815 `mqt-cc` overlap by preserving its + JEFF and QCO program pipeline and adding OQ3/Math dialect registration. + Removed the provisional changelog entry because it lacked the now-required + PR and author references. +- [x] (2026-07-15 11:35Z) Rebuilt after the rebase and reran focused and + regression tests. The 24 OQ3 tests, 224 QC translation tests, and expanded + 116-test compiler suite passed. An `mqt-cc --emit=qc-import` smoke test + parsed and printed textual OQ3 IR alongside the new JEFF-aware driver. +- [x] (2026-07-15 11:40Z) Ran `uvx nox -s lint` on the rebased tree. Every + formatting, spelling, license, metadata, Python, and type-checking hook + passed. +- [x] (2026-07-15 11:48Z) Re-read the checkout-independent ExecPlan rules from + PR #1908, regenerated this plan to use only repository-relative scope, + paths, commands, and coordination boundaries, and verified the result with + `uvx nox -s lint`. +- [ ] Complete faithful signed and unsigned integer semantics, the remaining + scalar cast and operator rules, and typed non-bit program inputs and + outputs. +- [ ] Add checked grammar and semantic coverage for arrays, aliases, + subroutines, externs, switch, break, continue, timing, calibration, + annotations, and pragmas. Unsupported families must remain explicit + diagnostics until implemented. +- [ ] Add broader upstream conformance, differential, dominance, overflow, and + performance tests. Record parser and emitter scaling evidence. +- [ ] After PR #1603 is present on `main`, add an isolated lowering change for + the exponent forms supported by QC and diagnose unsupported downstream + forms. +- [ ] Switch the convenience translation path only after differential tests + demonstrate parity for the supported surface and a human approves retiring + the legacy behavior. + +## Surprises & Discoveries + +- Observation: MLIR arithmetic operations generally require signless integer + types, so mapping both OpenQASM `int` and `uint` directly to builtin integer + types loses the source signedness needed to choose comparisons, extensions, + division, and casts. Evidence: the prototype currently documents complete + signed/unsigned semantics as planned rather than claiming conformance. + +- Observation: OpenQASM permits a range step to be a runtime value while also + requiring it to be nonzero. The current QC and JEFF path has no faithful + runtime assertion or trap for this condition. Evidence: typed `oq3.for` + accepts a dynamic integer step, while QC lowering emits + `dynamic range step cannot be proven nonzero for the selected target`. + +- Observation: comparison-driven loop lowering avoids both division by zero and + endpoint overflow. Evidence: the focused range tests cover positive, negative, + empty, singleton, non-divisible, and maximum-width endpoints, with a widened + internal induction value. + +- Observation: the repository typo fixer interpreted MLIR's ordered-less-than + floating-point predicate as a spelling error and changed the identifier, + causing a compilation failure. Evidence: the predicate now carries a + line-scoped spelling suppression and the rebuilt focused suite passes. + +- Observation: PR #1815 completely reworked `mqt-cc`, added JEFF input/output, + and replaced the former compiler-pipeline interface with the `Programs` + abstraction and composable pass pipelines. Evidence: rebasing produced + conflicts only in `mlir/tools/mqt-cc/CMakeLists.txt` and + `mlir/tools/mqt-cc/mqt-cc.cpp`; resolution retained the new driver and added + only the required OQ3 registrations. + +- Observation: PR #1907 introduced the ExecPlan process after the first + prototype commits had already been created. Evidence: this file records the + completed work retrospectively and becomes the authoritative living plan for + every subsequent iteration. + +- Observation: PR #1908 clarified that a checked-in ExecPlan is shared project + documentation rather than a record of one machine's orchestration state. + Evidence: this revision removes the former machine-specific scope block, cache + setup, and worktree-administration instructions while retaining + repository-relative coordination boundaries. + +## Decision Log + +- Decision: Start from `origin/main`, not PR #1862. Rationale: `main` retains a + separated parser, semantic passes, and established OpenQASM 2 tests, whereas + #1862's direct parser-to-MLIR emission is the architectural element being + replaced. Date/Author: 2026-07-15 / Codex. + +- Decision: Use a small typed `oq3` dialect as a semantic high-level + intermediate representation, not as a syntax tree and not with Any-like + operands. Rationale: valid source constructs must remain representable before + every target supports them, while builtin MLIR dialects should continue to + represent ordinary classical computation. Date/Author: 2026-07-15 / Codex. + +- Decision: Track OpenQASM 3.1 as the sole current 3.x version, accept + versionless input as 3.1, reject explicit 3.0, and normalize supported + OpenQASM 2 syntax into the same typed representation. Rationale: this matches + the project's one-current-standard policy while preserving required legacy + input. Date/Author: 2026-07-15 / Codex. + +- Decision: Keep generated grammar sources committed and isolated, with an exact + upstream revision and a documented local spelling correction. Rationale: + builds must not require parser generation or expose ANTLR implementation + details through public headers. Date/Author: 2026-07-15 / Codex. + +- Decision: Preserve a dynamic range step in typed OQ3 but reject it during QC + lowering when nonzero cannot be proven. Rationale: it is valid typed source, + but silently treating zero as an empty range or generating unsafe arithmetic + would change program meaning. Date/Author: 2026-07-15 / Codex. + +- Decision: Preserve `pow` modifiers in OQ3 and do not eagerly expand them. + Rationale: QC power support belongs to PR #1603; the frontend must parse the + full modifier without guessing downstream semantics. Date/Author: 2026-07-15 / + Codex. + +- Decision: Keep `translateQASM3ToQC` and `.qasm` handling on the legacy path + until parity tests pass. Rationale: the demonstrator is not yet a complete + replacement and the legacy importer is a valuable differential oracle. + Date/Author: 2026-07-15 / Codex. + +- Decision: Integrate with #1815 by registering OQ3 and Math in its new + JEFF-aware `mqt-cc` dialect registry rather than restoring any deleted + `CompilerPipeline` code. Rationale: the merged program abstraction is now the + repository architecture and the OQ3 change only needs textual IR support at + this stage. Date/Author: 2026-07-15 / Codex. + +- Decision: Do not add a changelog entry until a human-reviewed PR number and + complete author list are available. Rationale: current `AGENTS.md` requires + both for changelog entries. Date/Author: 2026-07-15 / Codex. + +- Decision: Keep this ExecPlan independent of any checkout, developer account, + local filesystem layout, or ephemeral branch. Rationale: PR #1908 makes the + plan a portable repository artifact that must be usable from any clone. + Date/Author: 2026-07-15 / Codex. + +## Outcomes & Retrospective + +The first demonstrator milestone produced a verified typed boundary and proved +that the proposed architecture can coexist with the current importer. It +supports representative gates, ordered modifiers, broadcasting, measurements, +mutable scalar and bit state, structured control flow, inclusive ranges, +standard-library includes, and OpenQASM 2 compatibility. It also demonstrates +the intended diagnostic split: syntax and semantic errors occur in the frontend, +while dynamic range steps and power modifiers fail as explicit target capability +limitations. + +The milestone does not yet meet the final goal of arbitrary OpenQASM 3.1 input. +The most important semantic gap is faithful integer signedness; the largest +feature gaps are aggregate classical types, callable constructs, advanced +control flow, timing, and calibration. The test suite establishes a useful +foundation but still needs imported conformance examples and measured scaling. +Keeping the legacy importer active was the right risk-control decision. The +rebase of PR #1815 confirms that the OQ3 layer can remain additive while the +compiler driver evolves independently. + +## Context and Orientation + +OpenQASM is a source language for quantum programs. The generated ANTLR parser +under `mlir/lib/Target/OpenQASM/Generated` recognizes its grammar. ANTLR is a +parser generator; its generated C++ code turns source text into a parse tree but +does not establish source types or target behavior. The reviewed grammar files +are under `mlir/lib/Target/OpenQASM/Grammar`, and their upstream revision is +recorded in `mlir/lib/Target/OpenQASM/README.md`. + +The staged frontend implementation is `mlir/lib/Target/OpenQASM/OpenQASM.cpp`, +with its public interface in `mlir/include/mlir/Target/OpenQASM/OpenQASM.h`. Its +`translateOpenQASMToOQ3` entry point accepts either an LLVM source manager or an +in-memory string and returns a verified MLIR module. An LLVM source manager owns +the main file and included buffers so diagnostics can retain filenames, line +numbers, and include context. + +The `oq3` dialect is defined under `mlir/include/mlir/Dialect/OQ3` and +implemented under `mlir/lib/Dialect/OQ3`. A dialect is an MLIR vocabulary of +types and operations with verifiers. This dialect adds only source distinctions +that builtin MLIR or existing MQT quantum dialects cannot faithfully retain, +including fixed-width bit values, angles, source gate symbols and applications, +ordered modifiers, and inclusive source ranges. Ordinary arithmetic, functions, +structured control flow, and mutable storage use the builtin `arith`, `math`, +`func`, `scf`, and `memref` dialects. + +The lowering pass is `mlir/lib/Dialect/OQ3/Transforms/LowerOQ3ToQC.cpp`. It +rewrites supported OQ3 operations to the existing QC dialect and builtin +operations. A target capability diagnostic means the source is typed and valid +but the selected downstream representation cannot preserve it yet. This is +intentionally different from a source semantic diagnostic. + +Focused tests live in `mlir/unittests/Target/OpenQASM/test_openqasm.cpp`. The +established importer and its regression fixtures remain under the QC translation +tests. Documentation of the deliberately conservative feature boundary lives in +`docs/mlir/OpenQASM.md`. + +PR #1815, now part of `main`, added Python bindings for compiler programs, +replaced `CompilerPipeline` with `Programs`, and made `mqt-cc` understand QC, +QCO, JEFF, and QIR flows through explicit passes. The OQ3 prototype does not +replace that design. It only registers the OQ3 and Math dialects so textual OQ3 +modules can be read; the production QASM input path remains unchanged until +parity is demonstrated. + +## Plan of Work + +First, keep the grammar dependency reproducible. Preserve the pinned grammar, +generated sources, provenance note, and isolated CMake target. When updating the +grammar, review upstream changes, regenerate all outputs in one operation, and +rerun parser-focused tests rather than hand-editing generated code. + +Second, stabilize the typed representation before expanding features. Add tests +for every type and operation verifier, symbol lookup, modifier operand, scope, +and invalid programmatically constructed form. Resolve integer signedness in a +way that keeps arithmetic on MLIR-compatible signless integer values while +carrying enough semantic information to select signed or unsigned operations. Do +not introduce an untyped fallback operation. + +Third, extend semantic construction family by family. For each grammar family, +either construct verified typed IR or emit one precise feature-named diagnostic. +Add tests for both success and failure. Preserve declared input and output +order, source locations, lexical scopes, and dominance. Mutable classical values +must remain in storage or explicit region-carried values; quantum SSA values +must cross regions as arguments and results rather than through a global side +table. + +Fourth, extend lowering independently of parsing. A valid OQ3 operation may +remain unlowered until QC and JEFF have matching semantics. Lower positive and +negative inclusive ranges through widened comparison-driven control flow. Add +power lowering only after #1603 exists on `main`, and keep unsupported exponent +forms as target diagnostics. + +Fifth, grow objective evidence. Import reviewed upstream examples, add +differential tests for programs supported by both importers, verify every +produced module, and benchmark a flat gate stream, nested expressions, +standard-library loading, and repeated custom gates. Require approximately +linear parser and emitter growth and avoid eager gate expansion in frontend +construction. + +Finally, consider switching the convenience API only after the staged path has +parity for its advertised surface, all regression tests pass, and a human has +reviewed the generated changes. Keep the dialect explicitly experimental until +its operation shapes and lowering boundary have proven stable. + +## Concrete Steps + +Run every command in this section from the repository root. Configure the debug +preset first when `build/debug` does not exist: + + cmake --preset debug + +To rebuild the driver and focused test after a change, run: + + cmake --build --preset debug \ + --target mqt-cc mqt-core-mlir-unittest-openqasm-target -j4 + +The build should finish with no failed compilation or link steps. Then run: + + ./build/debug/mlir/unittests/Target/OpenQASM/\ + mqt-core-mlir-unittest-openqasm-target + +The expected current result is 24 passing tests. Build and run the established +translation regression binary with: + + cmake --build --preset debug \ + --target mqt-core-mlir-unittest-qc-translation -j4 + ./build/debug/mlir/unittests/Dialect/QC/Translation/\ + mqt-core-mlir-unittest-qc-translation + +The expected baseline is 224 passing tests. The compiler regression binary is: + + cmake --build --preset debug \ + --target mqt-core-mlir-unittests-compiler -j4 + ./build/debug/mlir/unittests/Compiler/\ + mqt-core-mlir-unittests-compiler + +The expected baseline at the first milestone was 110 passing tests. PR #1815 may +change the count; success means every discovered test passes. + +After each completed batch, run: + + uvx nox -s lint + git diff --check origin/main...HEAD + git status --short --branch + +If lint reports an apparently unrelated diagnostic, verify it against an +unmodified `origin/main` before recording it here. PR #1815 changed the formerly +known `SparsePauliOp` typing line, so that prior limitation must not be assumed +for later revisions. + +## Validation and Acceptance + +A source containing explicit `OPENQASM 3.1;` or no version declaration must +produce a verified typed OQ3 module for the supported surface. Explicit 3.0 must +produce an unsupported-version diagnostic. Explicit 2.0 must activate the +compatibility syntax, including `qelib1.inc` and legacy measurement arrows. + +Standard gates must be unavailable unless the correct standard library is +included. Custom gates must reject unknown symbols, use before definition, +recursion, incorrect arity, and incompatible broadcasting. Modifier order and +dynamic modifier operands must be visible in typed OQ3 IR. Power must remain a +target diagnostic until supported by QC. + +A constant zero range step must fail semantic analysis. A runtime step must +verify in OQ3 but fail initial QC lowering with the exact target diagnostic.

A caller should be able to parse a source file, perform +source-language semantic analysis, inspect a verified typed representation, and +then request target lowering. Source errors and target-capability errors must be +different failures. + +The implementation will extend MQT Core's existing handwritten `qasm3` lexer, +recursive-descent parser, abstract syntax model, constant evaluator, and type +checker. It will not use ANTLR. The parser will produce syntax only; a separate +semantic analyzer will resolve names, scopes, types, constants, overloads, gate +signatures, and include policy into an arena-owned typed program. A small +experimental OQ3 MLIR dialect will preserve source concepts for which builtin +MLIR has no faithful equivalent. A dedicated emitter will map the already typed +program to OQ3 plus builtin, `arith`, `math`, `func`, `scf`, and `memref` +operations. The emitter must not repeat source typing. + +A human can observe the intended separation through three focused test layers. +Parser tests accept or reject syntax without constructing MLIR. Semantic tests +produce typed programs or source-spanned diagnostics without an MLIR context. +Emitter and lowering tests accept typed programs or programmatically built OQ3 +IR, verify the module, and distinguish malformed IR from unsupported target +features. + +The repository-relative scope is `include/mqt-core/qasm3`, `src/qasm3`, their +existing tests, the experimental dialect under `mlir/include/mlir/Dialect/OQ3` +and `mlir/lib/Dialect/OQ3`, the future adapter under +`mlir/include/mlir/Target/OpenQASM` and `mlir/lib/Target/OpenQASM`, focused +tests, and directly related build and documentation files.

Repository lint passed - except for the then-existing unrelated `ty` diagnostic in - `python/mqt/core/plugins/qiskit/estimator.py:235`. -- [x] (2026-07-15 11:25Z) Fetched and analyzed merged PRs #1815 and #1907, - fast-forwarded canonical `main`, re-read `AGENTS.md`, `.agent/PLANS.md`, - and `docs/ai_usage.md`, and rebased the implementation onto commit - `a228a3dc2`. -- [x] (2026-07-15 11:28Z) Resolved the #1815 `mqt-cc` overlap by preserving its - JEFF and QCO program pipeline and adding OQ3/Math dialect registration. - Removed the provisional changelog entry because it lacked the now-required - PR and author references. -- [x] (2026-07-15 11:35Z) Rebuilt after the rebase and reran focused and - regression tests. The 24 OQ3 tests, 224 QC translation tests, and expanded - 116-test compiler suite passed.

The historical implementation + remains in Git history for comparison. +- [x] (2026-07-15 13:40Z) Added semantics-preserving QC lowering for `cu`, + `cu3`, and `cu1`.

Evidence: the prototype currently documents complete - signed/unsigned semantics as planned rather than claiming conformance. - -- Observation: OpenQASM permits a range step to be a runtime value while also - requiring it to be nonzero. The current QC and JEFF path has no faithful - runtime assertion or trap for this condition. Evidence: typed `oq3.for` - accepts a dynamic integer step, while QC lowering emits - `dynamic range step cannot be proven nonzero for the selected target`. - -- Observation: comparison-driven loop lowering avoids both division by zero and - endpoint overflow. Evidence: the focused range tests cover positive, negative, - empty, singleton, non-divisible, and maximum-width endpoints, with a widened - internal induction value. - -- Observation: the repository typo fixer interpreted MLIR's ordered-less-than - floating-point predicate as a spelling error and changed the identifier, - causing a compilation failure. Evidence: the predicate now carries a - line-scoped spelling suppression and the rebuilt focused suite passes. - -- Observation: PR #1815 completely reworked `mqt-cc`, added JEFF input/output, - and replaced the former compiler-pipeline interface with the `Programs` - abstraction and composable pass pipelines. Evidence: rebasing produced - conflicts only in `mlir/tools/mqt-cc/CMakeLists.txt` and - `mlir/tools/mqt-cc/mqt-cc.cpp`; resolution retained the new driver and added - only the required OQ3 registrations. - -- Observation: PR #1907 introduced the ExecPlan process after the first - prototype commits had already been created. Evidence: this file records the - completed work retrospectively and becomes the authoritative living plan for - every subsequent iteration. - -- Observation: PR #1908 clarified that a checked-in ExecPlan is shared project - documentation rather than a record of one machine's orchestration state. - Evidence: this revision removes the former machine-specific scope block, cache - setup, and worktree-administration instructions while retaining - repository-relative coordination boundaries. +- Observation: MQT Core's mainline OpenQASM implementation is not based on + generated ANTLR code. `src/qasm3/Scanner.cpp` and `src/qasm3/Parser.cpp` are a + handwritten scanner and recursive-descent parser; `ConstEvalPass.cpp` and + `TypeCheckPass.cpp` already separate two semantic concerns from parsing. This + makes extension and consolidation lower risk than introducing a second parser + stack. + +- Observation: Qiskit's reported eighty-fold parsing speedup is a README claim + from a crude large-file comparison, not a reproducible benchmark in that + repository. The architectural evidence is still useful: its custom lexer feeds + an event-based recursive-descent and Pratt parser, a source-spanned syntax + tree, and a distinct typed abstract semantic graph. Its repository has no + Criterion benchmark or checked benchmark data supporting the exact factor. + +- Observation: The removed ANTLR demonstrator combined parsing-tree traversal, + source semantic checks, symbol state, builtin MLIR construction, and OQ3 + emission in one `SemanticBuilder`. The public function was staged in name but + not internally separated. This confirmed Daniel's concern that another + refactor would otherwise restart from the same coupled architecture. + +- Observation: Operation-level MLIR verifiers cannot prove every OpenQASM + invariant. Operand shape and type relationships are local, while recursive + gates, declaration order, symbol visibility, and some modifier relationships + need surrounding-program information. A single defensive whole-program + verifier is required for programmatically constructed IR, but it must not + become the source semantic analyzer. + +- Observation: The legacy gate catalog intentionally accepts many names beyond + the strict OpenQASM standard-library set. This is user-facing convenience, not + accidental parser behavior. Strict conformance and compatibility require an + explicit gate-policy choice rather than silently dropping or globally + injecting those names. + +- Observation: OpenQASM's four-parameter `cu(theta, phi, lambda, gamma)` is not + exactly `ctrl @ U(theta, phi, lambda)`: it also applies `p(gamma)` to the + control. Native lowering must retain that relative phase. The three-parameter + `cu3` and one-parameter `cu1` aliases map directly to controlled U and + controlled P. + +- Observation: Direct use of `arith` and `memref` is not itself a layering + problem. It becomes a problem only if those operations are built while source + typing is still being decided. Emitting them from an already typed semantic + program avoids duplicating an entire classical OQ3 operation set and keeps the + semantic boundary clear. ## Decision Log -- Decision: Start from `origin/main`, not PR #1862. Rationale: `main` retains a - separated parser, semantic passes, and established OpenQASM 2 tests, whereas - #1862's direct parser-to-MLIR emission is the architectural element being - replaced. Date/Author: 2026-07-15 / Codex. - -- Decision: Use a small typed `oq3` dialect as a semantic high-level - intermediate representation, not as a syntax tree and not with Any-like - operands. Rationale: valid source constructs must remain representable before - every target supports them, while builtin MLIR dialects should continue to - represent ordinary classical computation. Date/Author: 2026-07-15 / Codex. - -- Decision: Implement one current OpenQASM 3 semantic mode based on 3.1, accept - explicit 3.0 and 3.1 declarations into that same mode, default versionless - input to it, and normalize supported OpenQASM 2 syntax into the same typed - representation. Rationale: callers should not be rejected solely for a 3.0 - declaration when the frontend can interpret the program with the maintained - OpenQASM 3 semantics. Date/Author: 2026-07-15 / Codex. - -- Decision: Keep generated grammar sources committed and isolated, with an exact - upstream revision and a documented local spelling correction. Rationale: - builds must not require parser generation or expose ANTLR implementation - details through public headers. Date/Author: 2026-07-15 / Codex. - -- Decision: Preserve a dynamic range step in typed OQ3 but reject it during QC - lowering when nonzero cannot be proven. Rationale: it is valid typed source, - but silently treating zero as an empty range or generating unsafe arithmetic - would change program meaning. Date/Author: 2026-07-15 / Codex. - -- Decision: Preserve `pow` modifiers in OQ3 and do not eagerly expand them. - Rationale: QC power support belongs to PR #1603; the frontend must parse the - full modifier without guessing downstream semantics. Date/Author: 2026-07-15 / - Codex. - -- Decision: Keep `translateQASM3ToQC` and `.qasm` handling on the legacy path - until parity tests pass. Rationale: the demonstrator is not yet a complete - replacement and the legacy importer is a valuable differential oracle. +- Decision: Remove ANTLR and the direct parse-tree-to-MLIR demonstrator now. + Rationale: the implementation is preserved in Git history, while keeping it on + the branch would impose a large dependency and generated-code review burden on + an architecture that is being replaced. Date/Author: 2026-07-15 / Codex, + following maintainer direction. + +- Decision: Extend MQT Core's handwritten frontend and take architectural + inspiration, but no copied implementation, from Qiskit's parser. Rationale: + the existing C++ scanner, parser, AST, source debug information, type checker, + constant evaluator, OpenQASM 2 support, and native gates provide a practical + base. A Rust dependency or a transliteration of rust-analyzer's red/green tree + would add cost without first proving a repository-specific benefit. Date/Author: 2026-07-15 / Codex. -- Decision: Integrate with #1815 by registering OQ3 and Math in its new - JEFF-aware `mqt-cc` dialect registry rather than restoring any deleted - `CompilerPipeline` code. Rationale: the merged program abstraction is now the - repository architecture and the OQ3 change only needs textual IR support at - this stage. Date/Author: 2026-07-15 / Codex. +- Decision: Define three explicit internal stages: `parseOpenQASM` returns a + syntax program, `analyzeOpenQASM` returns a typed semantic program, and + `emitOQ3` returns MLIR. `translateOpenQASMToOQ3` only composes them. + Rationale: source typing remains testable without MLIR, and emission cannot + silently add a second source type system. Date/Author: 2026-07-15 / Codex. + +- Decision: Perform source semantic analysis during typed-program construction + in one primary traversal. Rationale: this is the efficient place to maintain + lexical scopes, resolve symbols, fold required constants, and attach types and + diagnostics. Operation verifiers defend IR invariants; they do not replace + language analysis. Date/Author: 2026-07-15 / Codex. + +- Decision: Preserve original source spans in syntax and semantic nodes. + Rationale: semantic diagnostics should use the source manager directly, and + every emitted MLIR operation should receive a file/line/column range derived + from the same span. Downstream diagnostics then remain useful without trying + to reconstruct source positions from MLIR. Date/Author: 2026-07-15 / Codex. + +- Decision: Use builtin MLIR, `arith`, `math`, `func`, `scf`, and `memref` after + semantic analysis whenever their semantics match. Retain OQ3 operations only + for source distinctions such as bit versus bool, angles, source gate symbols + and ordered modifiers, inclusive ranges, timing, and calibration. In + particular, emit ordinary `scf.if` and `scf.while` directly; retain `oq3.for` + while its inclusive range and dynamic nonzero-step contract cannot be + represented faithfully by a standard SCF operation. Date/Author: 2026-07-15 / + Codex. + +- Decision: Keep a strict specification gate policy and an MQT compatibility + gate policy. The staged experimental API defaults to strict mode. Existing + convenience import APIs retain compatibility mode until an intentional public + migration. Both policies draw from one canonical gate catalog containing + availability, arity, native QC mapping, and aliases. Date/Author: 2026-07-15 / + Codex. -- Decision: Do not add a changelog entry until a human-reviewed PR number and - complete author list are available. Rationale: current `AGENTS.md` requires - both for changelog entries. Date/Author: 2026-07-15 / Codex. +- Decision: Implement `cu`, `cu3`, and `cu1` natively and never expand them to + source gate definitions merely to lower them. Rationale: QC already represents + their primitive operations and controls; direct lowering is linear, preserves + dynamic parameters, and retains the legacy convenience. Date/Author: + 2026-07-15 / Codex. -- Decision: Keep this ExecPlan independent of any checkout, developer account, - local filesystem layout, or ephemeral branch. Rationale: PR #1908 makes the - plan a portable repository artifact that must be usable from any clone. +- Decision: Maintain one current OpenQASM 3 semantic profile based on 3.1. + Explicit 3.0 and 3.1 declarations and versionless input use that profile; + explicit 2.0 uses compatibility normalization. Rationale: MQT tracks one + maintained revision while avoiding unnecessary rejection of 3.0 headers. Date/Author: 2026-07-15 / Codex. ## Outcomes & Retrospective -The first demonstrator milestone produced a verified typed boundary and proved -that the proposed architecture can coexist with the current importer. It -supports representative gates, ordered modifiers, broadcasting, measurements, -mutable scalar and bit state, structured control flow, inclusive ranges, -standard-library includes, and OpenQASM 2 compatibility. It also demonstrates -the intended diagnostic split: syntax and semantic errors occur in the frontend, -while dynamic range steps and power modifiers fail as explicit target capability -limitations. - -The milestone does not yet meet the final goal of arbitrary OpenQASM 3 input. -The most important semantic gap is faithful integer signedness; the largest -feature gaps are aggregate classical types, callable constructs, advanced -control flow, timing, and calibration. The test suite establishes a useful -foundation but still needs imported conformance examples and measured scaling. -Keeping the legacy importer active was the right risk-control decision. The -rebase of PR #1815 confirms that the OQ3 layer can remain additive while the -compiler driver evolves independently. +The first architecture demonstrator established that a small typed OQ3 dialect +can preserve gates, ordered modifiers, bit values, and inclusive ranges while +lowering supported operations to QC. Review then exposed that its frontend +boundary was only nominal: the ANTLR visitor still decided source semantics +while emitting MLIR. The useful dialect and lowering work has been retained, and +the parser stack has been removed before more features accumulated around the +wrong boundary. + +The revised foundation reuses project knowledge instead of restarting. The +handwritten parser remains incomplete and its shared-pointer AST is not the +desired final ownership model, but it already contains tested OpenQASM 2 +compatibility, native gate behavior, source debug information, expression +parsing, constant evaluation, and type checking. The next milestone must make +those layers explicit and arena-owned before reconnecting OQ3 emission. Until +then, the draft is an architecture workbench rather than a replacement frontend. ## Context and Orientation -OpenQASM is a source language for quantum programs. The generated ANTLR parser -under `mlir/lib/Target/OpenQASM/Generated` recognizes its grammar. ANTLR is a -parser generator; its generated C++ code turns source text into a parse tree but -does not establish source types or target behavior. The reviewed grammar files -are under `mlir/lib/Target/OpenQASM/Grammar`, and their upstream revision is -recorded in `mlir/lib/Target/OpenQASM/README.md`. - -The staged frontend implementation is `mlir/lib/Target/OpenQASM/OpenQASM.cpp`, -with its public interface in `mlir/include/mlir/Target/OpenQASM/OpenQASM.h`. Its -`translateOpenQASMToOQ3` entry point accepts either an LLVM source manager or an -in-memory string and returns a verified MLIR module. An LLVM source manager owns -the main file and included buffers so diagnostics can retain filenames, line -numbers, and include context. - -The `oq3` dialect is defined under `mlir/include/mlir/Dialect/OQ3` and -implemented under `mlir/lib/Dialect/OQ3`. A dialect is an MLIR vocabulary of -types and operations with verifiers. This dialect adds only source distinctions -that builtin MLIR or existing MQT quantum dialects cannot faithfully retain, -including fixed-width bit values, angles, source gate symbols and applications, -ordered modifiers, and inclusive source ranges. Ordinary arithmetic, functions, -structured control flow, and mutable storage use the builtin `arith`, `math`, -`func`, `scf`, and `memref` dialects. - -The lowering pass is `mlir/lib/Dialect/OQ3/Transforms/LowerOQ3ToQC.cpp`. It -rewrites supported OQ3 operations to the existing QC dialect and builtin -operations. A target capability diagnostic means the source is typed and valid -but the selected downstream representation cannot preserve it yet. This is -intentionally different from a source semantic diagnostic. - -Focused tests live in `mlir/unittests/Target/OpenQASM/test_openqasm.cpp`. The -established importer and its regression fixtures remain under the QC translation -tests. Documentation of the deliberately conservative feature boundary lives in -`docs/mlir/OpenQASM.md`. - -PR #1815, now part of `main`, added Python bindings for compiler programs, -replaced `CompilerPipeline` with `Programs`, and made `mqt-cc` understand QC, -QCO, JEFF, and QIR flows through explicit passes. The OQ3 prototype does not -replace that design. It only registers the OQ3 and Math dialects so textual OQ3 -modules can be read; the production QASM input path remains unchanged until -parity is demonstrated. +`src/qasm3/Scanner.cpp` converts source characters to `qasm3::Token` values. +`src/qasm3/Parser.cpp` is a handwritten recursive-descent parser that constructs +the classes declared in `include/mqt-core/qasm3/Statement.hpp`. Expressions are +currently heap allocated through `std::shared_ptr`; source information is a +`DebugInfo` containing one line and column plus an include-parent chain. + +`src/qasm3/passes/ConstEvalPass.cpp` and `src/qasm3/passes/TypeCheckPass.cpp` +traverse the syntax objects. The importer in `src/qasm3/Importer.cpp` currently +invokes both passes statement by statement and then immediately emits a +`qc::QuantumComputation`. This preserves some separation but does not expose a +complete typed program and can report only one failure at a time. + +The new source layer will introduce `SourceId`, `SourceSpan`, and `Diagnostic` +under `include/mqt-core/qasm3`. A source ID identifies one main or included +buffer. A source span is a half-open byte range within that buffer. A diagnostic +contains severity, message, primary span, and optional related spans. Line and +column text is computed only when displaying a diagnostic, so scanning and +semantic analysis use compact offsets. + +The syntax layer will own nodes in arenas and refer to them by small IDs instead +of recursive shared ownership. `SyntaxProgram` records statements and +expressions exactly as parsed, including unsupported families. The parser uses +recursive descent for statements and a Pratt parser for expressions. A Pratt +parser is a precedence-driven expression parser that handles prefix, infix, and +postfix operators in one table. Error recovery synchronizes at semicolons, +braces, and declaration or statement starters so one run can report multiple +independent errors. + +The semantic layer will produce `TypedProgram`. Each expression has a resolved +OpenQASM type and each identifier use has a `SymbolId`; mutable declarations, +constants, gate definitions, inputs, outputs, ranges, and callable signatures +carry their source spans. This program is the only source-language semantic +truth consumed by both the circuit importer and the OQ3 emitter. + +The OQ3 dialect lives under `mlir/include/mlir/Dialect/OQ3` and +`mlir/lib/Dialect/OQ3`. OQ3 is a semantic high-level IR, not a syntax tree. Its +operation verifiers check local shape and type invariants. One module-level +verification pass checks cross-operation symbol resolution, declaration order, +recursion, and modifier relationships for programmatically constructed IR. The +pass runs once after emission; it should diagnose compiler bugs or malformed +textual OQ3, not repeat source analysis. ## Plan of Work -First, keep the grammar dependency reproducible. Preserve the pinned grammar, -generated sources, provenance note, and isolated CMake target. When updating the -grammar, review upstream changes, regenerate all outputs in one operation, and -rerun parser-focused tests rather than hand-editing generated code. - -Second, stabilize the typed representation before expanding features. Add tests -for every type and operation verifier, symbol lookup, modifier operand, scope, -and invalid programmatically constructed form. Resolve integer signedness in a -way that keeps arithmetic on MLIR-compatible signless integer values while -carrying enough semantic information to select signed or unsigned operations. Do -not introduce an untyped fallback operation. - -Third, extend semantic construction family by family. For each grammar family, -either construct verified typed IR or emit one precise feature-named diagnostic. -Add tests for both success and failure. Preserve declared input and output -order, source locations, lexical scopes, and dominance. Mutable classical values -must remain in storage or explicit region-carried values; quantum SSA values -must cross regions as arguments and results rather than through a global side -table. - -Fourth, extend lowering independently of parsing. A valid OQ3 operation may -remain unlowered until QC and JEFF have matching semantics. Lower positive and -negative inclusive ranges through widened comparison-driven control flow. Add -power lowering only after #1603 exists on `main`, and keep unsupported exponent -forms as target diagnostics. - -Fifth, grow objective evidence. Import reviewed upstream examples, add -differential tests for programs supported by both importers, verify every -produced module, and benchmark a flat gate stream, nested expressions, -standard-library loading, and repeated custom gates. Require approximately -linear parser and emitter growth and avoid eager gate expansion in frontend -construction. - -Finally, consider switching the convenience API only after the staged path has -parity for its advertised surface, all regression tests pass, and a human has -reviewed the generated changes. Keep the dialect explicitly experimental until -its operation shapes and lowering boundary have proven stable. +The first milestone leaves a clean non-ANTLR base. Keep the OQ3 dialect and +lowering, remove every ANTLR dependency and generated source, and move tests +that exercise the dialect or lowering into `mlir/unittests/Dialect/OQ3` using +programmatically built IR. Test native `cu`, `cu3`, and `cu1` lowering, +including the `gamma` phase of four-parameter `cu`. Acceptance is that the build +contains no ANTLR target or generated parser and the OQ3 tests pass +independently of any source parser. + +The second milestone makes upstream syntax measurable ground truth. Add a +pinned, unmodified OpenQASM 3.1 grammar and conformance-example snapshot under +`vendor/openqasm/` with upstream revision, license, hashes, and a regeneration +script. These files are test data, not compiled parser input, and are excluded +from typo fixing, license rewriting, and auto-formatting just like other +vendored sources. Generate a checked coverage manifest that maps every grammar +production to positive and negative parser tests. Add OpenQASM 2 fixtures +already supported by main. Acceptance is that CI can identify missing +productions and the normal build has no parser-generator dependency. + +The third milestone refactors scanning and parsing. Add source-buffer ownership, +byte spans, structured diagnostics, arena-owned syntax nodes, recovery, and a +Pratt expression table while preserving the existing parser API through a +temporary adapter. Port statement families incrementally and run legacy and new +syntax tests together. Acceptance is complete syntax coverage, multiple useful +diagnostics from one invalid file, accurate include-stack spans, and linear +token and parse growth. + +The fourth milestone builds one semantic analyzer. Consolidate symbol scopes, +type checking, required constant evaluation, gate lookup, broadcasting, +input/output ordering, version policy, and include policy into +`analyzeOpenQASM`. It emits `TypedProgram` only if no source semantic errors +remain. Unsupported target features are still representable. Acceptance is that +semantic tests run without MLIR and cover unknown, recursive, +use-before-defined, arity, type, width, index, scope, cast, range-step, and +compatibility failures with original source spans. + +The fifth milestone reconnects MLIR through a thin adapter. Implement +`translateOpenQASMToOQ3` as parse, analyze, emit. `emitOQ3` maps typed values to +builtin storage and arithmetic, uses SCF directly where faithful, emits only +source-specific OQ3 operations where needed, attaches range locations, and does +not perform source type inference. Add the module-level OQ3 verifier and keep +the textual dialect experimental. Acceptance is that every successful module +verifies and an injected malformed module fails the defensive verifier at the +source-derived operation location. + +The sixth milestone preserves compatibility deliberately. Move the standard, +qelib1, and MQT-native names into one gate catalog. Strict mode makes only `U` +and `gphase` language builtins and loads standard libraries only when included. +Compatibility mode preserves the legacy implicit native catalog, including +additional MQT operations and aliases. Inventory every existing legacy name and +classify it as specification, qelib1, alias, or MQT extension. Acceptance is +that no gate silently changes availability and every native mapping has a QC +lowering test. + +The final milestones complete source families and objective evidence. Add +arrays, aliases, subroutines and externs, switch and loop control, timing, +annotations, pragmas, calibration, and power lowering as downstream dialects +permit. Differentially compare both importers over their overlap. Benchmark a +flat gate stream, nested expressions, includes, and repeated custom gates at +increasing sizes. Require approximately linear growth, bounded diagnostic +recovery, no eager custom-gate expansion, and no expression-string cache keys or +shared-pointer ownership in the new syntax and semantic programs. ## Concrete Steps -Run every command in this section from the repository root.

Its parser creates a flat event stream before +building a source-spanned syntax tree; its semantic context owns an abstract +semantic graph, scoped symbol table, constant map, and semantic-error list. This +plan adopts the separation and measurable stage boundaries, not the Rust crate +layout or implementation. + +Daniel's review questions are answered as follows. Source semantic analysis +belongs in typed-program construction and uses original source spans. Local OQ3 +verifiers check operation invariants. One whole-program verifier checks the few +cross-operation invariants that cannot be local. OQ3 emission is a separate +linear walk and may use `arith`, `memref`, and SCF because source typing has +already completed.

This ExecPlan must be maintained in accordance with `.agent/PLANS.md` from the repository root. ## Purpose / Big Picture -MQT Core needs one maintainable OpenQASM frontend that accepts OpenQASM 3 and -the supported OpenQASM 2 compatibility syntax, reports precise source -diagnostics, and can preserve valid source constructs even when QC or JEFF -cannot lower them yet. A caller should be able to parse a source file, perform -source-language semantic analysis, inspect a verified typed representation, and -then request target lowering. Source errors and target-capability errors must be -different failures. - -The implementation will reuse MQT Core's existing handwritten `qasm3` lexer and -recursive-descent parser as its initial syntax source. It will not use ANTLR. -The MLIR frontend will own a separate semantic model and analyzer rather than -making the legacy `QuantumComputation` importer or its mutable environments the -architectural center. Sharing scanner and parser infrastructure is acceptable; -duplicating semantic utilities is preferable when that keeps the MLIR stages -clean. A separate semantic analyzer will resolve names, scopes, types, -constants, overloads, gate signatures, and include policy into an arena-owned -typed program. A small experimental OQ3 MLIR dialect will preserve source -concepts for which builtin MLIR has no faithful equivalent. A dedicated emitter -will map the already typed program to OQ3 plus builtin, `arith`, `math`, `func`, -`scf`, and `memref` operations. The emitter must not repeat source typing. - -A human can observe the intended separation through three focused test layers. -Parser tests accept or reject syntax without constructing MLIR. Semantic tests -produce typed programs or source-spanned diagnostics without an MLIR context. -Emitter and lowering tests accept typed programs or programmatically built OQ3 -IR, verify the module, and distinguish malformed IR from unsupported target -features. - -The repository-relative scope is `include/mqt-core/qasm3`, `src/qasm3`, their -existing tests, the experimental dialect under `mlir/include/mlir/Dialect/OQ3` -and `mlir/lib/Dialect/OQ3`, the future adapter under -`mlir/include/mlir/Target/OpenQASM` and `mlir/lib/Target/OpenQASM`, focused -tests, and directly related build and documentation files. The existing -`QuantumComputation` importer stays available as a behavioral oracle, but it is -not required to adopt the MLIR semantic program. The production MLIR -`translateQASM3ToQC` entry point is replaced by the staged frontend in this -milestone rather than retaining two MLIR translation implementations. Unrelated -changes and other worktrees remain outside scope. +MQT Core needs an OpenQASM frontend that separates source-language validity from +target capability. Parsing and semantic analysis must work without an MLIR +context, valid programs must produce verified target-neutral IR, and a separate +conversion must either produce verified QC or report a precise target +limitation. This distinction is observable with a valid `pow`-modified gate: +analysis and OQ3 emission succeed, while conversion reports that QC cannot +represent power modifiers. + +The frontend must support real source programs, not only isolated syntax. That +includes lexical scope, mutable scalar and bit state, `for`, `while`, `if`, +loop-carried values, includes, custom gates, dynamic indices, measurement, and +OpenQASM 2 compatibility behavior. Ordinary arithmetic and structured control +flow use standard MLIR dialects.

The legacy +`QuantumComputation` parser remains available and its tests remain regression +coverage; it is not used as an adapter by the MLIR frontend. ## Progress -- [x] (2026-07-15 10:10Z) Started from current main and kept the established - importer available as a comparison oracle. -- [x] (2026-07-15 10:50Z) Added the experimental OQ3 types, gate operations, - inclusive range operation, local verifiers, and initial OQ3-to-QC - lowering. -- [x] (2026-07-15 11:40Z) Integrated the compiler architecture from pull request - 1815 and adopted the ExecPlan process introduced and refined by pull - requests 1907 and 1908. -- [x] (2026-07-15 12:00Z) Established the version policy: explicit 3.0, explicit - 3.1, and versionless input select the same maintained OpenQASM 3 - semantics; explicit 2.0 selects compatibility mode. -- [x] (2026-07-15 13:20Z) Inspected Daniel's public and private feedback, MQT - Core's existing parser and semantic passes, the legacy native-gate - catalog, and Qiskit's `openqasm3_parser` source at commit - `3eac9970f37baf6d030a3a185b9421cca3cf0a59`. -- [x] (2026-07-15 13:40Z) Removed the ANTLR runtime, generated parser, grammar - target, direct parse-tree-to-MLIR builder, frontend tests tied to that - builder, and generated-file lint exceptions.

Four-parameter `cu` retains its control-qubit phase; - `cu3` lowers to controlled U and `cu1` to controlled P. -- [x] (2026-07-15 13:50Z) Added parser-independent OQ3 verifier and lowering - tests, rebuilt OQ3 and `mqt-cc`, and passed 3 focused OQ3 tests, 224 - existing QC translation tests, and 116 compiler tests. -- [x] (2026-07-15 13:50Z) Passed repository lint, inspected and committed the - architecture pivot, rebased onto current `origin/main` at `559fde4b2`, and - repeated the focused OQ3, QC translation, and compiler tests. -- [x] (2026-07-15 13:55Z) Force-pushed the rebased branch with lease protection - and updated draft pull request 1910 to describe the handwritten-parser - architecture and current workbench status. -- [x] (2026-07-15 14:10Z) Expanded the delivery decision: replace the existing - MLIR OpenQASM-to-QC translator immediately with parse, analyze, emit OQ3, - and lower OQ3 stages; keep the legacy `QuantumComputation` importer - independent and duplicate semantic code where sharing would couple them. -- [x] (2026-07-15 15:10Z) Introduced MLIR-owned opaque parsed-program and - value-oriented typed-program APIs. Parsing and semantic-analysis tests run - without constructing an MLIR context and retain source filenames and - line/column diagnostics. -- [x] (2026-07-15 15:40Z) Added typed-program-to-OQ3 emission and made - `translateQASM3ToQC` a thin composition of parse, analyze, emit, verify, - and lower stages. -- [x] (2026-07-15 15:55Z) Deleted the 1,114-line direct AST-to-QC visitor. All - 117 existing OpenQASM translation fixtures now pass through the staged - replacement, including the established OpenQASM 2 compatibility cases. -- [ ] Establish a checked upstream grammar and conformance snapshot as test - ground truth, without making generated code or ANTLR a build dependency. -- [ ] Refactor the existing scanner and parser to return a source-spanned syntax - program with recovery and multiple diagnostics (completed: one - precedence-climbing table now parses the complete scalar binary-operator - hierarchy, including right-associative `**`; remaining: byte spans, arena - ownership, recovery, and unsupported syntax families). -- [ ] Replace the separate legacy constant/type passes with one semantic - analyzer that produces an arena-owned typed program consumed by both the - circuit importer and OQ3 emitter. -- [ ] Implement the thin parse/analyze/emit translation API and one defensive - whole-program OQ3 verifier for cross-operation invariants. -- [ ] Complete OpenQASM 3 grammar and semantic coverage, OpenQASM 2 - normalization, differential tests, and measured linear scaling. -- [x] (2026-07-15 16:05Z) Added dedicated stage-boundary tests proving semantic - analysis is MLIR-independent, OQ3 verifies before lowering, and the - production convenience wrapper leaves no OQ3 operations after lowering. -- [x] (2026-07-15 16:25Z) Made standard-library availability explicit in the - typed program. Strict mode requires `include "stdgates.inc";`, while the - default compatibility mode preserves implicit native-gate convenience; - user definitions may use unavailable standard-library names in strict - mode. -- [x] (2026-07-15 16:35Z) Added typed mixed-numeric gate expressions with - signed/unsigned MLIR casts, preserved valid `pow` modifiers through OQ3, - and covered inverse native aliases. Passed 4 OQ3 tests, 10 staged-frontend - tests, 224 translation tests, and 116 downstream compiler tests from a - clean rebuild. -- [x] (2026-07-15 17:11Z) Simplified alternating `ctrl` and `negctrl` lowering - to recursive single-control regions. Negative-control polarity flips are - emitted once around the outermost modifier tree, and existing QC - canonicalization still combines adjacent controls for compact target IR. - Added a focused alternating-modifier test and retained all 224 QC - translation parity results. -- [x] (2026-07-15 17:30Z) Added typed OQ3 emission for `sin`, `cos`, `tan`, - `exp`, `ln`, and `sqrt`, and replaced the parser's incomplete expression - ladder with the OpenQASM precedence hierarchy. Power now uses `**` and is - right associative; `^` now means bitwise XOR; modulo, shifts, bitwise, - logical, equality, and comparison operators all parse at their specified - precedence. All 98 QASM parser tests and 12 staged-frontend tests pass. -- [x] (2026-07-15 18:10Z) Performed two independent MLIR-focused reviews of the - draft and stabilized the accepted local invariants: OQ3 gate and range - regions now require `oq3.yield`; gate applications reject surplus qubits - without controls and non-integer control counts; variadic native gates - retain their declared minimum arity; duplicate qubits and unsupported - integer declarations receive source diagnostics; and explicit unsupported - OpenQASM 3 minor versions are rejected. Added target and verifier tests, - including a constant-zero range step that must fail before it can form an - infinite target loop. -- [x] (2026-07-15 18:25Z) Fixed the OQ3 dialect documentation target after the - draft pull request's Read the Docs build reported that multiple dialects - occur in `OQ3Ops.td`. The generated OQ3 operation definition now shares - that file with the dialect definition, so `add_mlir_doc` explicitly - selects `oq3`; `OQ3DialectDocGen` builds successfully. -- [x] (2026-07-15 19:15Z) Made the exact Read the Docs command pass. Escaped a - portable CMake regular-expression literal, added the OQ3 dialect page to - the MLIR toctree, and generated its pass reference beneath `Passes/` so no - orphaned generated Markdown page reaches Sphinx. -- [x] (2026-07-15 19:15Z) Added a scoped `mlir/.clang-tidy` policy based on the - upstream MLIR check set. It retains correctness and performance checks - suitable for MLIR while avoiding repository-wide checks that diagnose - generated operation code and intentional MLIR conventions. -- [x] (2026-07-15 19:25Z) Addressed the remaining PR lint diagnostics in source - rather than broadening suppressions: removed two redundant constant moves, - made the parser operator table's members explicit, converted the implicit - statement counter deliberately, and initialized the defensive unary-op - fallback. The complete lint gate and focused parser/frontend tests pass. -- [x] (2026-07-15 19:45Z) Added behavior-driven staged-frontend tests for custom - gates in conditionals, reset and barrier emission, OpenQASM 2 controlled - gate compatibility prefixes, and observable diagnostics for unmeasured - outputs, unmeasured conditions, zero controls, and mixed broadcast - operands. All 20 focused frontend tests pass. -- [x] (2026-07-15 19:55Z) Added a direct staged-translation regression for the - OpenQASM language builtin `gphase` and physical `$` qubit operands; it - confirms both survive semantic analysis and lower to the intended QC - operations. All 21 focused frontend tests pass. -- [x] (2026-07-15 20:15Z) Reproduced the Read the Docs build configuration and - built the exact `mqt-core-docs` target. Added the missing direct TableGen - dependency from `MLIROpenQASMTarget` to `MLIROQ3OpsIncGen`, ensuring - `OQ3OpsDialect.h.inc` exists before consumers compile.

Identified the + stream parser bridge, unreachable loop support, and missing carried state + as release blockers. +- [x] (2026-07-15) Moved OQ3-to-QC into `mlir/Conversion/OQ3ToQC`, implemented + it with MLIR dialect conversion, made OQ3 illegal after conversion, and + removed speculative OQ3 classical and loop concepts. +- [x] (2026-07-16) Replaced the `SourceMgr`-to-`std::istringstream` bridge with + an LLVM-native, zero-copy lexer and recursive-descent parser that produce + persistent syntax and collected `SMLoc` diagnostics. +- [x] (2026-07-16) Centralized names, types, scope, initialization, gate + availability, and source restrictions in semantic analysis. Added exact + version handling, textual includes, strict UTF-8 identifiers, constants, + assignments, comparisons, broadcasting, and dynamic index checks. +- [x] (2026-07-16) Implemented source `if`, `for`, and `while` with standard SCF + operations.

All + focused binaries, 97 legacy parser tests, warning-as-error documentation, + repository lint, and diff checks pass. Refreshed substantive + changed-surface line coverage is 91.4 percent. ## Surprises & Discoveries -- Observation: MQT Core's mainline OpenQASM implementation is not based on - generated ANTLR code. `src/qasm3/Scanner.cpp` and `src/qasm3/Parser.cpp` are a - handwritten scanner and recursive-descent parser; `ConstEvalPass.cpp` and - `TypeCheckPass.cpp` already separate two semantic concerns from parsing. This - makes extension and consolidation lower risk than introducing a second parser - stack. - -- Observation: Qiskit's reported eighty-fold parsing speedup is a README claim - from a crude large-file comparison, not a reproducible benchmark in that - repository. The architectural evidence is still useful: its custom lexer feeds - an event-based recursive-descent and Pratt parser, a source-spanned syntax - tree, and a distinct typed abstract semantic graph. Its repository has no - Criterion benchmark or checked benchmark data supporting the exact factor. - -- Observation: The removed ANTLR demonstrator combined parsing-tree traversal, - source semantic checks, symbol state, builtin MLIR construction, and OQ3 - emission in one `SemanticBuilder`. The public function was staged in name but - not internally separated. This confirmed Daniel's concern that another - refactor would otherwise restart from the same coupled architecture. - -- Observation: Operation-level MLIR verifiers cannot prove every OpenQASM - invariant. Operand shape and type relationships are local, while recursive - gates, declaration order, symbol visibility, and some modifier relationships - need surrounding-program information. A single defensive whole-program - verifier is required for programmatically constructed IR, but it must not - become the source semantic analyzer. - -- Observation: The legacy gate catalog intentionally accepts many names beyond - the strict OpenQASM standard-library set. This is user-facing convenience, not - accidental parser behavior. Strict conformance and compatibility require an - explicit gate-policy choice rather than silently dropping or globally - injecting those names. - -- Observation: OpenQASM's four-parameter `cu(theta, phi, lambda, gamma)` is not - exactly `ctrl @ U(theta, phi, lambda)`: it also applies `p(gamma)` to the - control. Native lowering must retain that relative phase. The three-parameter - `cu3` and one-parameter `cu1` aliases map directly to controlled U and - controlled P. - -- Observation: Direct use of `arith` and `memref` is not itself a layering - problem. It becomes a problem only if those operations are built while source - typing is still being decided. Emitting them from an already typed semantic - program avoids duplicating an entire classical OQ3 operation set and keeps the - semantic boundary clear. - -- Observation: the shared parser injects a synthetic `cu` declaration, but its - current `DebugInfo` is created after the include scanner has unwound and can - therefore name the main source buffer. The new analyzer recognizes this - parser-owned declaration structurally for now. The parser refactor must mark - synthetic declarations explicitly instead of inferring provenance from a - filename. - -- Observation: the repository's broad `target/` ignore pattern also matches - MLIR's conventional capitalized `Target/` source directories on - case-insensitive filesystems. Narrow exceptions are required for the new - source and test targets while retaining the build-artifact ignore. - -- Observation: `qc.ctrl` already has a `MergeNestedCtrl` canonicalization that - combines adjacent nested controls. The OQ3 lowerer can therefore construct the - direct recursive semantics without duplicating grouping logic, while the - standard QC cleanup pipeline still produces the compact multi-control form - used by existing consumers and parity tests. - -- Observation: the handwritten expression parser recognized tokens for all - scalar operators but parsed only arithmetic and comparison subsets. It also - interpreted `^` as power and gave comparisons higher precedence than addition. - The maintained OpenQASM hierarchy uses right-associative `**` for power and - `^` for bitwise XOR, followed by unary, multiplicative, additive, shift, - comparison, equality, bitwise, and logical levels. - -- Observation: a local operation verifier must defend IR created outside the - source frontend. `oq3.apply_gate` previously accepted surplus qubits and - control-count operands of arbitrary scalar type; `GateOp` and `ForOp` did not - require the terminator that lowering omits while cloning. These are malformed - typed IR, not source-language analysis concerns. Local checks and - `SingleBlockImplicitTerminator` traits preserve that boundary. - -- Observation: accepting an `int` or `uint` declaration and emitting it as a - `bit` register silently changes signedness, width semantics, and stored - values. The analyzer now rejects those declarations until typed storage and - assignment lowering exist. - -- Observation: the Read the Docs environment treats the `\.` escape in a quoted - CMake string as a developer warning, whereas the local configuration did not - expose it before OQ3 documentation generation reached the cleanup script. - CMake requires `\\.` in the source string for a literal dot in the regular - expression. - -- Observation: Codecov's C++ patch status is red for substantive missing test - coverage, not because the coverage job failed. Its report for this branch has - 1,065 covered and 322 missed patch lines (76.78%). The coverage target must be - met by exercising error paths, custom gates, lowering variants, and parser - diagnostics rather than by changing Codecov policy. +- Observation: the previous MLIR entry point copied the `SourceMgr` main buffer + into `std::istringstream` and invoked the legacy scanner and parser. The + source manager therefore did not own included source or parser locations. + Evidence: the replacement can destroy the caller's source manager and still + diagnose and emit from included buffers. + +- Observation: the legacy scanner recognized `for` and `while`, but its parser + had no statement cases for them. The prior OQ3 loop operation was therefore + unreachable from source. Evidence: the new source fixtures exercise both forms + and inspect their emitted SCF regions. + +- Observation: pull request 1862 contains useful zero-copy lexing mechanics, + scope and loop grammar, and broad behavior fixtures, but its parser and sink + share semantic decisions and emit MLIR immediately. Its mechanics and tests + are reusable; its architecture is incompatible with a persistent typed stage. + +- Observation: mutable outer values cannot be represented by retaining SSA + values created inside a branch or loop. Those values do not dominate later + uses. Explicit SCF region arguments, yields, and results are required, and + carrying only transitively mutated values keeps signatures small. + +- Observation: OpenQASM integer ranges are inclusive, may descend, and may span + the full signed 64-bit domain. Normalizing them through i128 distance + arithmetic avoids `stop + 1` overflow and makes dynamic zero steps and + unrepresentable trip counts explicit assertions. + +- Observation: parser-owned symbol resolution fails for textual includes because + declarations become visible according to include expansion order, not buffer + parse order. A grammar-only parser and one semantic pass correctly handle + included declarations and declaration-before-use rules. + +- Observation: the QC qubit type has reference semantics. Loading a dynamic + element again can create an alias that QC-to-QCO cannot represent, and a + qubit-valued `arith.select` is not lowerable. Structured `scf.if` dispatch + applies operations to canonical register references in each branch. + +- Observation: dialect-conversion worklist order does not guarantee that a + structured terminator sees the final values produced in its region. A second + conversion phase for `scf.yield` and `scf.condition`, sharing region-local + maps with the first phase, makes value threading deterministic. + +- Observation: QCO structured conditionals carry linear quantum state but not + arbitrary classical results. QC-to-QCO therefore spills branch-local classical + measurement results into distinct one-element scratch slots hoisted outside + enclosing loops while keeping quantum values in SSA form. + +- Observation: direct dynamic dispatch grows as the Cartesian product of dynamic + operands. The 4,096-leaf budget prevents exponential IR construction before it + starts and is also checked when a caller directly mutates a `TypedProgram`. + +- Observation: a successful whole-module conversion can still visit OQ3 calls + inside unused gate definitions. Erasing unreachable definitions before + conversion prevents unused recursion or doubling chains from blocking or + expanding otherwise valid programs. + +- Observation: the repository-wide hook wrapper consults the shared Git index + and can report missing-file metadata for intentional unstaged deletions. + Running every hook over all live changed and untracked paths validates the + same surface without staging work that has not been approved. ## Decision Log -- Decision: Remove ANTLR and the direct parse-tree-to-MLIR demonstrator now. - Rationale: the implementation is preserved in Git history, while keeping it on - the branch would impose a large dependency and generated-code review burden on - an architecture that is being replaced. Date/Author: 2026-07-15 / Codex, - following maintainer direction. - -- Decision: Extend MQT Core's handwritten frontend and take architectural - inspiration, but no copied implementation, from Qiskit's parser. Rationale: - the existing C++ scanner, parser, AST, source debug information, type checker, - constant evaluator, OpenQASM 2 support, and native gates provide a practical - base. A Rust dependency or a transliteration of rust-analyzer's red/green tree - would add cost without first proving a repository-specific benefit. - Date/Author: 2026-07-15 / Codex. - -- Decision: Define three explicit internal stages: `parseOpenQASM` returns a - syntax program, `analyzeOpenQASM` returns a typed semantic program, and - `emitOQ3` returns MLIR. `translateOpenQASMToOQ3` only composes them. - Rationale: source typing remains testable without MLIR, and emission cannot - silently add a second source type system. Date/Author: 2026-07-15 / Codex. - -- Decision: Perform source semantic analysis during typed-program construction - in one primary traversal. Rationale: this is the efficient place to maintain - lexical scopes, resolve symbols, fold required constants, and attach types and - diagnostics. Operation verifiers defend IR invariants; they do not replace - language analysis. Date/Author: 2026-07-15 / Codex. - -- Decision: Preserve original source spans in syntax and semantic nodes. - Rationale: semantic diagnostics should use the source manager directly, and - every emitted MLIR operation should receive a file/line/column range derived - from the same span. Downstream diagnostics then remain useful without trying - to reconstruct source positions from MLIR. Date/Author: 2026-07-15 / Codex. - -- Decision: Use builtin MLIR, `arith`, `math`, `func`, `scf`, and `memref` after - semantic analysis whenever their semantics match. Retain OQ3 operations only - for source distinctions such as bit versus bool, angles, source gate symbols - and ordered modifiers, inclusive ranges, timing, and calibration. In - particular, emit ordinary `scf.if` and `scf.while` directly; retain `oq3.for` - while its inclusive range and dynamic nonzero-step contract cannot be - represented faithfully by a standard SCF operation. Date/Author: 2026-07-15 / +- Decision: retain a minimal OQ3 dialect for resolved gates and ordered + modifiers. Rationale: `pow` demonstrates valid source semantics that QC cannot + represent, while standard MLIR already models classical values and structured + control flow. Date/Author: 2026-07-15 / Codex. + +- Decision: implement OQ3-to-QC as dialect conversion with OQ3 illegal in the + final target. Rationale: success then proves mechanically that no OQ3 + operation remains. Date/Author: 2026-07-15 / Codex. + +- Decision: adapt selected mechanics and all healthy behavior fixtures from pull + request 1862 without adopting its direct parser-to-emitter design. Rationale: + parsing must produce persistent target-independent data and semantic rules + must have one owner. Date/Author: 2026-07-15 / Codex. + +- Decision: keep the parser grammar-only and use one syntax expression graph for + arithmetic, conditions, indices, and measurements. Rationale: names, types, + scope, initialization, and gate order belong in semantic analysis, especially + across textual includes. Date/Author: 2026-07-16 / Codex. + +- Decision: represent ordinary control flow with SCF and thread only + transitively mutated scalar and bit state. Rationale: SCF provides the + required dominance and region contracts without duplicating them in OQ3. + Date/Author: 2026-07-16 / Codex. + +- Decision: normalize inclusive ranges to a zero-based positive SCF trip count + using i128 calculations. Rationale: this handles ascending, descending, + dynamic, empty, and boundary ranges without source-width overflow. + Date/Author: 2026-07-16 / Codex. + +- Decision: perform definite-initialization analysis and use `ub.poison` only + for emitter slots proven unreachable before initialization. Rationale: the + emitter must not invent source values. Date/Author: 2026-07-16 / Codex. + +- Decision: follow the OpenQASM C99 conversion rules consistently in constant + folding and MLIR emission. Rationale: mixed `int`, `uint`, float, comparison, + and assignment behavior must agree at compile time and run time. Date/Author: + 2026-07-16 / Codex. + +- Decision: treat standard-library includes as ordered events and custom + includes as cached syntax expanded once per occurrence. Rationale: this + preserves textual visibility while avoiding repeated lexing and still detects + active recursive expansion. Date/Author: 2026-07-16 / Codex. + +- Decision: allow gate bodies to read parameters, loop variables, built-in + constants, and immutable global constants, but reject mutable global captures. + Rationale: immutable values can be embedded safely; mutable values would + create closure-like references in emitted gate symbols. Date/Author: + 2026-07-16 / Codex. + +- Decision: use structured dispatch over canonical QC references for dynamic + qubit indices and cap expansion at 4,096 leaves. Rationale: this preserves + alias identity and downstream conversion while bounding generated IR. + Date/Author: 2026-07-16 / Codex. + +- Decision: preflight custom-gate reachability and expansion, convert reachable + gate bodies before call sites, and reject modifiers on structured custom gates + that QC cannot represent. Rationale: target conversion must never drop + semantics or introduce fresh illegal operations. Date/Author: 2026-07-16 / Codex. -- Decision: Keep a strict specification gate policy and an MQT compatibility - gate policy. The staged experimental API and existing convenience import API - default to compatibility mode so the architectural replacement does not - silently remove long-standing native gate names. Strict mode is explicit. Both - policies draw from one canonical gate catalog containing availability, arity, - native QC mapping, and aliases. Date/Author: 2026-07-15 / Codex. - -- Decision: Implement `cu`, `cu3`, and `cu1` natively and never expand them to - source gate definitions merely to lower them. Rationale: QC already represents - their primitive operations and controls; direct lowering is linear, preserves - dynamic parameters, and retains the legacy convenience. Date/Author: - 2026-07-15 / Codex. - -- Decision: Maintain one current OpenQASM 3 semantic profile based on 3.1. - Explicit 3.0 and 3.1 declarations and versionless input use that profile; - explicit 2.0 uses compatibility normalization. Rationale: MQT tracks one - maintained revision while avoiding unnecessary rejection of 3.0 headers. - Date/Author: 2026-07-15 / Codex. - -- Decision: Replace the production MLIR translation path in this branch instead - of keeping the direct AST-to-QC implementation as a fallback. Rationale: two - live MLIR importers would obscure which semantics are authoritative and would - postpone the most valuable architectural test. The existing QC translation - tests remain the oracle, and Git history provides rollback. Date/Author: - 2026-07-15 / Codex, following maintainer direction. - -- Decision: Reuse the handwritten scanner and parser initially, but give the - MLIR frontend its own value-oriented typed program and semantic analyzer. Do - not require the legacy `QuantumComputation` importer to consume that model. - Rationale: syntax sharing avoids gratuitous parser duplication while semantic - independence permits clean source-to-MLIR design and incremental grammar - improvements. Date/Author: 2026-07-15 / Codex, following maintainer direction. - -- Decision: Expose explicit include names and the count of parser-injected - statements as parser metadata without changing the legacy importer's default - behavior. Rationale: semantic policy must distinguish a source include from - the legacy parser's synthetic `cu` definition; checking a synthetic node's - filename was unreliable after scanner-stack unwinding. Date/Author: 2026-07-15 - / Codex. - -- Decision: Lower every expanded control as one recursive `qc.ctrl`, regardless - of whether the source modifier is positive or negative, and emit X gates for - every negative-control qubit before and after the entire modifier tree. - Rationale: polarity changes must not execute conditionally inside an earlier - positive control. This representation handles alternating controls and - inverses uniformly, and QC's existing canonicalization combines adjacent - controls when a compact form is desired. Date/Author: 2026-07-15 / Codex, - following maintainer feedback. - -- Decision: Replace the partial expression ladder now with a table-driven - precedence-climbing parser while retaining the existing public parser entry - points. Rationale: this fixes observable specification mismatches immediately - and establishes the core of the planned Pratt-style expression parser without - coupling syntax parsing to MLIR or forcing a simultaneous ownership rewrite. - Date/Author: 2026-07-15 / Codex. - -- Decision: Address only local, testable review findings in this stabilization - batch and defer SourceMgr-backed include resolution. Rationale: operation - verification, source arity, and version checks have narrow ownership and - direct regression tests. Reworking the parser's shared include stack needs a - dedicated MLIR adapter or duplicated resolver so it does not accidentally - perturb the legacy `QuantumComputation` importer. Date/Author: 2026-07-15 / - Codex. +- Decision: convert QC structured parents and quantum operations before their + terminators, using one region-local state model. Rationale: terminators must + resolve values after all branch or loop-body updates, independently of the + conversion driver's traversal order. Date/Author: 2026-07-16 / Codex. -- Decision: Use a scoped MLIR clang-tidy configuration rather than applying the - repository-wide configuration to MLIR sources. Rationale: the CI reports 265 - diagnostics from generated operation fragments and checks that do not match - MLIR's established conventions. The scoped configuration follows upstream - MLIR's intentionally narrower safety, modernization, and performance set; it - leaves the root configuration unchanged for the rest of MQT Core. Date/ - Author: 2026-07-15 / Codex. +- Decision: store frontend program IDs by canonical vector position and retain + only metadata consumed after analysis. Rationale: declaration IDs duplicated + their vector indices, gate parameter names were reduced immediately to counts, + and statement locations already identify gate applications. Scalar names + remain because source-order and include-identity tests inspect them. Removing + the other metadata makes the typed model smaller and its invariants explicit. + Date/Author: 2026-07-16 / Codex. ## Outcomes & Retrospective -The first architecture demonstrator established that a small typed OQ3 dialect -can preserve gates, ordered modifiers, bit values, and inclusive ranges while -lowering supported operations to QC. Review then exposed that its frontend -boundary was only nominal: the ANTLR visitor still decided source semantics -while emitting MLIR. The useful dialect and lowering work has been retained, and -the parser stack has been removed before more features accumulated around the -wrong boundary. - -The revised foundation reuses project knowledge instead of restarting. The -handwritten parser remains incomplete and its shared-pointer AST is not the -desired final ownership model, but it already contains tested OpenQASM 2 -compatibility, native gate behavior, source debug information, and expression -parsing. The MLIR-owned typed program now isolates those implementation details, -OQ3 emission is a separate walk, and the production MLIR entry point uses the -staged implementation exclusively. The legacy importer retains its current -constant and type passes and serves as the 117-fixture behavioral oracle. - -The latest iteration removed special-case control grouping from OQ3 lowering. -Alternating positive and negative controls now use one recursive rule, and the -existing QC cleanup still recovers multi-control operations. It also completed -the parser's scalar binary-operator precedence and added dynamic scalar math -function emission. Source spans, recovery, arena ownership, mutable classical -state, and the remaining statement families are still future milestones. +The completed architecture separates source concerns from target concerns. The +LLVM-native frontend owns source buffers and diagnostics, parsing produces +persistent syntax, semantic analysis produces a compact typed program, and +emission uses standard MLIR wherever the semantics are already expressible. OQ3 +retains the small gate/modifier boundary needed to distinguish valid source from +QC capability, and dialect conversion proves that successful QC output has no +residual OQ3 operations. + +The implementation now supports source loops, assignments, comparisons, lexical +shadowing, definite initialization, local bits, negative and dynamic indices, +compound arithmetic, general conditions, targetless and targeted measurement, +whole-register bit assignment, OpenQASM 2 classical-register conditions, Unicode +identifiers, custom includes, immutable constants in gate bodies, and mixed +register/scalar broadcasting. SCF iteration arguments and results solve the +original dominance problem for nested mutable state. + +Pull request 1862 is represented as behavior coverage rather than a second +frontend architecture. Seventeen imported programs compare exact QC and ten +exercise loop or dynamic-index structure. After cleanup, the focused evidence is +13 OQ3 tests, 87 staged frontend and target tests, 241 QC translation tests, 121 +QC-to-QCO tests, 97 legacy parser tests, and 91.4 percent substantive +changed-surface line coverage (4,348 of 4,759 lines). ## Context and Orientation -`src/qasm3/Scanner.cpp` converts source characters to `qasm3::Token` values. -`src/qasm3/Parser.cpp` is a handwritten recursive-descent parser that constructs -the classes declared in `include/mqt-core/qasm3/Statement.hpp`. Expressions are -currently heap allocated through `std::shared_ptr`; source information is a -`DebugInfo` containing one line and column plus an include-parent chain. - -`src/qasm3/passes/ConstEvalPass.cpp` and `src/qasm3/passes/TypeCheckPass.cpp` -traverse the syntax objects. The importer in `src/qasm3/Importer.cpp` currently -invokes both passes statement by statement and then immediately emits a -`qc::QuantumComputation`. This preserves some separation but does not expose a -complete typed program and can report only one failure at a time. - -The new source layer will introduce `SourceId`, `SourceSpan`, and `Diagnostic` -under `include/mqt-core/qasm3`. A source ID identifies one main or included -buffer. A source span is a half-open byte range within that buffer. A diagnostic -contains severity, message, primary span, and optional related spans. Line and -column text is computed only when displaying a diagnostic, so scanning and -semantic analysis use compact offsets. - -The syntax layer will own nodes in arenas and refer to them by small IDs instead -of recursive shared ownership. `SyntaxProgram` records statements and -expressions exactly as parsed, including unsupported families. The parser uses -recursive descent for statements and a Pratt parser for expressions. A Pratt -parser is a precedence-driven expression parser that handles prefix, infix, and -postfix operators in one table. Error recovery synchronizes at semicolons, -braces, and declaration or statement starters so one run can report multiple -independent errors. - -The semantic layer will produce `TypedProgram`. Each expression has a resolved -OpenQASM type and each identifier use has a `SymbolId`; mutable declarations, -constants, gate definitions, inputs, outputs, ranges, and callable signatures -carry their source spans. This program is the only source-language semantic -truth consumed by both the circuit importer and the OQ3 emitter. - -The OQ3 dialect lives under `mlir/include/mlir/Dialect/OQ3` and -`mlir/lib/Dialect/OQ3`. OQ3 is a semantic high-level IR, not a syntax tree. Its -operation verifiers check local shape and type invariants. One module-level -verification pass checks cross-operation symbol resolution, declaration order, -recursion, and modifier relationships for programmatically constructed IR. The -pass runs once after emission; it should diagnose compiler bugs or malformed -textual OQ3, not repeat source analysis. +`mlir/lib/Target/OpenQASM/Frontend.cpp` owns the source manager and returns an +opaque `ParsedProgram`. `OpenQASMLexer.cpp`, `OpenQASMParser.h`, +`OpenQASMSyntax.h`, and `OpenQASMSyntax.cpp` implement tokenization, grammar, +source recovery, and persistent target-independent syntax. +`OpenQASMSemantics.cpp` resolves that syntax into the `TypedProgram` declared in +`mlir/include/mlir/Target/OpenQASM/Frontend.h`. These stages do not depend on an +MLIR context. + +`mlir/lib/Target/OpenQASM/OpenQASM.cpp` emits the typed program using builtin +MLIR plus `arith`, `cf`, `func`, `math`, `memref`, `scf`, `ub`, QC, and OQ3. +Mutable state is held by standard SSA values and explicitly crosses SCF region +boundaries. Dynamic qubit references become structured dispatch over canonical +QC references rather than new loads or qubit-valued selection. + +`mlir/lib/Conversion/OQ3ToQC/OQ3ToQC.cpp` is the target boundary. It validates +and orders reachable custom gates, lowers supported OQ3 gate applications, +reports unsupported target semantics, erases gate symbols, and completes with +OQ3 marked illegal. + +`mlir/lib/Conversion/QCToQCO/QCToQCO.cpp` converts QC reference semantics to QCO +value semantics. Structured operations preserve their classical operands and +results while appending quantum values. Region-local mappings and a separate +terminator phase preserve the latest branch and loop state. + +Tests under `mlir/unittests/Target/OpenQASM` exercise parsing, analysis, OQ3 +emission, QC conversion, source diagnostics, and the imported fixture corpus. +Tests under `mlir/unittests/Dialect/OQ3`, +`mlir/unittests/Dialect/QC/Translation`, and `mlir/unittests/Conversion/QCToQCO` +defend the IR and conversion boundaries. ## Plan of Work -The first milestone leaves a clean non-ANTLR base. Keep the OQ3 dialect and -lowering, remove every ANTLR dependency and generated source, and move tests -that exercise the dialect or lowering into `mlir/unittests/Dialect/OQ3` using -programmatically built IR. Test native `cu`, `cu3`, and `cu1` lowering, -including the `gamma` phase of four-parameter `cu`. Acceptance is that the build -contains no ANTLR target or generated parser and the OQ3 tests pass -independently of any source parser. - -The second milestone makes upstream syntax measurable ground truth. Add a -pinned, unmodified OpenQASM 3.1 grammar and conformance-example snapshot under -`vendor/openqasm/` with upstream revision, license, hashes, and a regeneration -script. These files are test data, not compiled parser input, and are excluded -from typo fixing, license rewriting, and auto-formatting just like other -vendored sources. Generate a checked coverage manifest that maps every grammar -production to positive and negative parser tests. Add OpenQASM 2 fixtures -already supported by main. Acceptance is that CI can identify missing -productions and the normal build has no parser-generator dependency. - -The third milestone replaces the production MLIR translation before the full -parser refactor. Add an opaque parsed-program API around the existing parser and -an MLIR-independent, value-oriented typed program. Analyze declarations, gate -signatures and bodies, constants, operands, modifiers, broadcasting, -measurements, resets, barriers, and conditionals into that program. Emit OQ3, -builtin classical operations, SCF, and existing QC state operations from the -typed program. Make `translateQASM3ToQC` compose parsing, analysis, OQ3 -emission, verification, and OQ3-to-QC lowering, then remove the direct AST-to-QC -visitor. Acceptance is that no production MLIR path constructs QC while -resolving source types and all existing QC translation regressions run through -the staged path. - -The fourth milestone refactors scanning and parsing. Add source-buffer -ownership, byte spans, structured diagnostics, arena-owned syntax nodes, -recovery, and a Pratt expression table while preserving the existing parser API -through a temporary adapter. Port statement families incrementally and run -legacy and new syntax tests together. Acceptance is complete syntax coverage, -multiple useful diagnostics from one invalid file, accurate include-stack spans, -and linear token and parse growth. - -The fifth milestone completes the semantic analyzer. Consolidate symbol scopes, -type checking, required constant evaluation, gate lookup, broadcasting, -input/output ordering, version policy, and include policy into -`analyzeOpenQASM`. It emits `TypedProgram` only if no source semantic errors -remain. Unsupported target features are still representable. Acceptance is that -semantic tests run without MLIR and cover unknown, recursive, -use-before-defined, arity, type, width, index, scope, cast, range-step, and -compatibility failures with original source spans. - -The sixth milestone completes MLIR emission beyond the initial production -replacement. Implement `translateOpenQASMToOQ3` as parse, analyze, emit. -`emitOQ3` maps typed values to builtin storage and arithmetic, uses SCF directly -where faithful, emits only source-specific OQ3 operations where needed, attaches -range locations, and does not perform source type inference. Add the -module-level OQ3 verifier and keep the textual dialect experimental. Acceptance -is that every successful module verifies and an injected malformed module fails -the defensive verifier at the source-derived operation location. - -The seventh milestone preserves compatibility deliberately. Move the standard, -qelib1, and MQT-native names into one gate catalog. Strict mode makes only `U` -and `gphase` language builtins and loads standard libraries only when included. -Compatibility mode preserves the legacy implicit native catalog, including -additional MQT operations and aliases.

Do not record a +machine-specific MLIR path in this plan. ## Validation and Acceptance -Syntax acceptance requires exact recognition of the pinned OpenQASM 3 grammar, -the supported OpenQASM 2 compatibility grammar, comments, version placement, and -includes. Explicit `OPENQASM 3.0;`, explicit `OPENQASM 3.1;`, and no version -declaration select the same current OpenQASM 3 semantics. Unsupported explicit -versions receive a source-spanned diagnostic. - -Semantic acceptance requires one typed result per successful source program and -no MLIR dependency. Unknown symbols, use before definition, recursion, duplicate -bindings, incompatible types, illegal casts, arity, indexing, broadcasting, -input/output, and constant-zero range steps fail with primary and related source -spans where applicable. A runtime range step remains valid typed source. - -Emitter acceptance requires that ordinary classical computation uses builtin -MLIR dialects after semantic analysis and that every operation has a location -derived from its source span. `if` and `while` use SCF directly. Inclusive -ranges remain OQ3 until their semantics can be lowered safely. No Any-like type -or fallback operation is permitted. - -Lowering acceptance requires native `cu`, `cu3`, and `cu1`; ordered `inv`, -`ctrl`, and `negctrl`; safe positive and negative inclusive ranges; and clear -target diagnostics for dynamic zero risk and unsupported power forms. The -four-parameter `cu` test must observe both the control phase and controlled U. - -Performance acceptance requires approximately linear time and memory for flat -programs and no unexplained regression against the existing handwritten parser. -The Qiskit README's factor of eighty is context, not an acceptance target. Every -benchmark must identify the stage measured so parser time is not conflated with -semantic analysis or MLIR construction. - -Final replacement acceptance additionally requires all established OpenQASM 2 -regressions, representative OpenQASM 3 conformance programs, differential QC -equivalence, and full module verification. The current replacement has parity -over all 117 established translation fixtures; broader conformance remains a -later milestone. +Parsing is accepted when tokens and diagnostics retain source identity, includes +remain owned, multiple recoverable errors are returned as data, and no parser or +analyzer operation requires MLIR. Semantic analysis is accepted when valid +programs produce a typed program and invalid programs fail with source-located +diagnostics before emission. + +Emission is accepted when ordinary programs verify, source loops produce valid +SCF, nested mutable state crosses regions through explicit arguments and +results, and dynamic qubit operations use canonical references with bounded +structured dispatch. The valid `pow` program must still verify as OQ3. + +OQ3-to-QC is accepted when supported programs produce verified QC with no OQ3 +operations, while unsupported power or structured custom-gate modifiers fail +with target-specific diagnostics. Reachable recursion and excessive expansion +must fail; unreachable definitions must not affect valid programs. + +QC-to-QCO is accepted when structured branches and loops preserve original +classical results and final quantum values independent of conversion traversal +order. Dynamic measurement dispatch must remain valid through this conversion. + +Final acceptance requires all focused binaries and legacy parser tests to pass, +all 27 imported fixtures to assert behavior, documentation to build with +warnings as errors, repository hooks to pass over every live file, +`git diff --check origin/main` to succeed, and changed-surface substantive line +coverage to remain at least 90 percent. ## Idempotence and Recovery -Builds, tests, benchmarks, and lint are repeatable and write only ignored build -or temporary output. The vendored grammar snapshot is updated only through its -documented script and exact upstream revision; review its hashes and complete -diff after regeneration. +Configuration, builds, tests, documentation, lint, and coverage commands are +repeatable and write only ignored output. Coverage binaries must be run +sequentially after removing stale counters. -Parser migration is additive until parity. Keep adapters from old entry points -to the new syntax and semantic stages, then remove old ownership and passes only -after both consumers pass. If a milestone fails, retain the existing importer -and remove only the incomplete adapter. Do not restore the removed ANTLR files; -they remain recoverable from Git history for isolated comparison. +Do not restore the stream bridge or introduce a parser-to-emitter fallback if a +syntax family fails. Preserve the failing source test and repair the staged +frontend at the owning layer. Preserve unrelated user changes, do not modify +another task worktree, and require a clean task worktree before any rebase. -Before rebasing, require a clean task checkout, fetch `origin`, and rebase onto -`origin/main`. Preserve current mainline behavior in conflicts. Never reset or -clean another worktree, and never force-push without authorization. +This plan does not authorize pushing, changing pull request state, resolving +review threads, or publishing comments. Those actions require separate human +authorization. ## Artifacts and Notes -The inspected Qiskit snapshot divides its frontend into lexer, parser, syntax, -source-file, and semantics crates. Its parser creates a flat event stream before -building a source-spanned syntax tree; its semantic context owns an abstract -semantic graph, scoped symbol table, constant map, and semantic-error list. This -plan adopts the separation and measurable stage boundaries, not the Rust crate -layout or implementation. - -Daniel's review questions are answered as follows. Source semantic analysis -belongs in typed-program construction and uses original source spans. Local OQ3 -verifiers check operation invariants. One whole-program verifier checks the few -cross-operation invariants that cannot be local. OQ3 emission is a separate -linear walk and may use `arith`, `memref`, and SCF because source typing has -already completed. There is no repeated source semantic walk. - -No public GitHub comment or review is authorized by this plan alone. The draft -pull request may receive branch updates within the user's previously authorized -progress-tracking scope. Any agent-authored public text body must begin with -`🤖 *AI text below* 🤖`. +The original staged baseline was 7 OQ3 tests, 21 staged frontend and target +tests, and 224 QC translation tests.

Identified the - stream parser bridge, unreachable loop support, and missing carried state - as release blockers. -- [x] (2026-07-15) Moved OQ3-to-QC into `mlir/Conversion/OQ3ToQC`, implemented - it with MLIR dialect conversion, made OQ3 illegal after conversion, and - removed speculative OQ3 classical and loop concepts. -- [x] (2026-07-16) Replaced the `SourceMgr`-to-`std::istringstream` bridge with - an LLVM-native, zero-copy lexer and recursive-descent parser that produce - persistent syntax and collected `SMLoc` diagnostics. -- [x] (2026-07-16) Centralized names, types, scope, initialization, gate - availability, and source restrictions in semantic analysis. Added exact - version handling, textual includes, strict UTF-8 identifiers, constants, - assignments, comparisons, broadcasting, and dynamic index checks. -- [x] (2026-07-16) Implemented source `if`, `for`, and `while` with standard SCF - operations. Mutation analysis carries only state written by nested control - flow through region arguments, yields, and results. -- [x] (2026-07-16) Implemented canonical-reference dynamic-qubit dispatch, - runtime bounds and alias checks, physical/virtual addressing diagnostics, - and a 4,096-leaf expansion budget enforced at analysis and emitter trust - boundaries. -- [x] (2026-07-16) Hardened OQ3 gate signatures, modifiers, operand provenance, - custom-gate reachability, recursion, expansion cost, and structured custom - gate target errors. -- [x] (2026-07-16) Updated QC-to-QCO to preserve existing classical SCF state, - append quantum state, use region-local mappings, and convert structured - terminators only after their regions have established final values. -- [x] (2026-07-16) Ported all 27 healthy pull request 1862 fixtures. Seventeen - non-looping programs compare exact QC output and ten loop or dynamic-index - programs assert behavior-sensitive structural contracts. -- [x] (2026-07-16) Removed iteration artifacts from the complete effective diff: - obsolete cleanup scaffolding, duplicated declaration metadata, parallel - structured-value maps, stale test names, repetitive revision notes, and - incidental comments. -- [x] (2026-07-16) Rebuilt from clean build and documentation directories.

The substantive frontend and + emitter surface reached 90.7 percent line coverage. ## Surprises & Discoveries -- Observation: the previous MLIR entry point copied the `SourceMgr` main buffer - into `std::istringstream` and invoked the legacy scanner and parser. The - source manager therefore did not own included source or parser locations. - Evidence: the replacement can destroy the caller's source manager and still - diagnose and emit from included buffers. +- Observation: the old MLIR entry point copied the `SourceMgr` main buffer into + `std::istringstream`, losing the source manager's include and location model. + Evidence: the replacement parser consumes LLVM buffers directly and its + persistent program retains included source identity. - Observation: the legacy scanner recognized `for` and `while`, but its parser - had no statement cases for them. The prior OQ3 loop operation was therefore - unreachable from source. Evidence: the new source fixtures exercise both forms - and inspect their emitted SCF regions. - -- Observation: pull request 1862 contains useful zero-copy lexing mechanics, - scope and loop grammar, and broad behavior fixtures, but its parser and sink - share semantic decisions and emit MLIR immediately. Its mechanics and tests - are reusable; its architecture is incompatible with a persistent typed stage. - -- Observation: mutable outer values cannot be represented by retaining SSA - values created inside a branch or loop. Those values do not dominate later - uses. Explicit SCF region arguments, yields, and results are required, and - carrying only transitively mutated values keeps signatures small. - -- Observation: OpenQASM integer ranges are inclusive, may descend, and may span - the full signed 64-bit domain. Normalizing them through i128 distance - arithmetic avoids `stop + 1` overflow and makes dynamic zero steps and - unrepresentable trip counts explicit assertions. - -- Observation: parser-owned symbol resolution fails for textual includes because - declarations become visible according to include expansion order, not buffer - parse order. A grammar-only parser and one semantic pass correctly handle - included declarations and declaration-before-use rules. - -- Observation: the QC qubit type has reference semantics. Loading a dynamic - element again can create an alias that QC-to-QCO cannot represent, and a - qubit-valued `arith.select` is not lowerable. Structured `scf.if` dispatch - applies operations to canonical register references in each branch. - -- Observation: dialect-conversion worklist order does not guarantee that a - structured terminator sees the final values produced in its region. A second - conversion phase for `scf.yield` and `scf.condition`, sharing region-local - maps with the first phase, makes value threading deterministic. - -- Observation: QCO structured conditionals carry linear quantum state but not - arbitrary classical results. QC-to-QCO therefore spills branch-local classical - measurement results into distinct one-element scratch slots hoisted outside - enclosing loops while keeping quantum values in SSA form. - -- Observation: direct dynamic dispatch grows as the Cartesian product of dynamic - operands. The 4,096-leaf budget prevents exponential IR construction before it - starts and is also checked when a caller directly mutates a `TypedProgram`. - -- Observation: a successful whole-module conversion can still visit OQ3 calls - inside unused gate definitions. Erasing unreachable definitions before - conversion prevents unused recursion or doubling chains from blocking or - expanding otherwise valid programs. - -- Observation: the repository-wide hook wrapper consults the shared Git index - and can report missing-file metadata for intentional unstaged deletions. - Running every hook over all live changed and untracked paths validates the - same surface without staging work that has not been approved. + could not construct those statements. Evidence: the staged frontend now has + source fixtures that produce and exercise standard SCF regions. + +- Observation: valid source and target support are distinct, but a dialect is + not required to preserve that distinction. Evidence: the typed semantic + program already retains modifiers and source locations, so a QC emitter can + reject `pow @` before creating target IR. + +- Observation: the OQ3 dialect has shrunk to gate declarations, applications, + and modifiers while classical computation and control flow already use + standard MLIR. Its conversion mostly expands typed custom gates and maps a + gate catalog to QC, work that can be performed directly from the typed model. + +- Observation: the branch changes QC-to-QCO for structured classical and quantum + state, but that change has not yet been justified by the complete + OpenQASM-to-QIR path. The correct evidence is a parser-independent conversion + regression distilled from a failing full-chain source fixture, not the mere + existence of structured OpenQASM. + +- Observation: `runDefaultPipeline` covers QC to QCO optimization, QCO back to + QC, and QC to QIR, but intentionally does not include a Jeff round trip. + Therefore acceptance needs both an explicit public-API Jeff chain and a + separate `runDefaultPipeline` check. + +- Observation: structured control flow generally requires the Adaptive QIR + profile, while straight-line circuits can exercise both Base and Adaptive + profiles. Encoding expected failures as fixture flags would hide unsupported + behavior, so the corpus contains only names and sources and profile grouping + is expressed by the test suites that select it. + +- Observation: Jeff round trips preserved entry functions with observable bit + results, but `JeffToQCO` restored the `entry_point` marker only for + result-less functions. Evidence: the first explicit chain reached + reconstructed QC but Adaptive QIR reported that no entry point existed. The + native Jeff regression now proves that nonempty result types and the marker + survive together. + +- Observation: the Jeff representation cannot preserve the frontend's runtime + `cf.assert` bounds checks. Evidence: genuinely runtime-dynamic indexing + reaches verified QC and QCO but QCO-to-Jeff rejects `cf.assert`; an index + resolved by cleanup traverses the complete chain. This limitation is + documented rather than erased or hidden by an expected-failure fixture flag. ## Decision Log -- Decision: retain a minimal OQ3 dialect for resolved gates and ordered - modifiers. Rationale: `pow` demonstrates valid source semantics that QC cannot - represent, while standard MLIR already models classical values and structured - control flow. Date/Author: 2026-07-15 / Codex. - -- Decision: implement OQ3-to-QC as dialect conversion with OQ3 illegal in the - final target. Rationale: success then proves mechanically that no OQ3 - operation remains. Date/Author: 2026-07-15 / Codex. - -- Decision: adapt selected mechanics and all healthy behavior fixtures from pull - request 1862 without adopting its direct parser-to-emitter design. Rationale: - parsing must produce persistent target-independent data and semantic rules - must have one owner. Date/Author: 2026-07-15 / Codex. - -- Decision: keep the parser grammar-only and use one syntax expression graph for - arithmetic, conditions, indices, and measurements. Rationale: names, types, - scope, initialization, and gate order belong in semantic analysis, especially - across textual includes. Date/Author: 2026-07-16 / Codex. - -- Decision: represent ordinary control flow with SCF and thread only - transitively mutated scalar and bit state. Rationale: SCF provides the - required dominance and region contracts without duplicating them in OQ3. +- Decision: remove the OQ3 MLIR dialect and emit QC directly from the typed + frontend program. Rationale: OpenQASM is compiler input, and successful import + should mean that the program can enter the compiler's supported dialects. + Unsupported target concepts remain diagnosable from the typed source model. Date/Author: 2026-07-16 / Codex. -- Decision: normalize inclusive ranges to a zero-based positive SCF trip count - using i128 calculations. Rationale: this handles ascending, descending, - dynamic, empty, and boundary ranges without source-width overflow. +- Decision: retain the staged lexer, syntax, and semantic design. Rationale: + parsing, source-language validity, and target emission have different + responsibilities, and includes, scope, and precise diagnostics already rely on + that separation. Date/Author: 2026-07-16 / Codex. + +- Decision: keep the existing `oq3::frontend` namespace unless a narrow rename + is independently justified. Rationale: the namespace denotes the OpenQASM 3 + language frontend and is not itself an MLIR dialect; renaming every frontend + type would add churn without changing behavior. Only dialect-specific + identifiers must disappear. Date/Author: 2026-07-16 / Codex. + +- Decision: put direct emission in private `OpenQASMToQCEmitter.h` and + `OpenQASMToQCEmitter.cpp`, leaving `TranslateQASM3ToQC.cpp` as a small public + adapter. Rationale: a large emitter should not obscure the stable translation + entry points, and private files avoid exposing a second public API. Date/Author: 2026-07-16 / Codex. -- Decision: perform definite-initialization analysis and use `ub.poison` only - for emitter slots proven unreachable before initialization. Rationale: the - emitter must not invent source values. Date/Author: 2026-07-16 / Codex. +- Decision: rename the frontend library target to `MLIROpenQASMFrontend`. + Rationale: after emission moves to QC translation, the target contains only + lexing, parsing, persistent syntax, semantic analysis, and the gate catalog; + the name should describe that boundary. Date/Author: 2026-07-16 / Codex. -- Decision: follow the OpenQASM C99 conversion rules consistently in constant - folding and MLIR emission. Rationale: mixed `int`, `uint`, float, comparison, - and assignment behavior must agree at compile time and run time. Date/Author: - 2026-07-16 / Codex. +- Decision: keep custom-gate expansion limits and QC capability preflight in the + emitter.

Date/Author: + 2026-07-16 / Codex. ## Outcomes & Retrospective -The completed architecture separates source concerns from target concerns. The -LLVM-native frontend owns source buffers and diagnostics, parsing produces -persistent syntax, semantic analysis produces a compact typed program, and -emission uses standard MLIR wherever the semantics are already expressible. OQ3 -retains the small gate/modifier boundary needed to distinguish valid source from -QC capability, and dialect conversion proves that successful QC output has no -residual OQ3 operations. - -The implementation now supports source loops, assignments, comparisons, lexical -shadowing, definite initialization, local bits, negative and dynamic indices, -compound arithmetic, general conditions, targetless and targeted measurement, -whole-register bit assignment, OpenQASM 2 classical-register conditions, Unicode -identifiers, custom includes, immutable constants in gate bodies, and mixed -register/scalar broadcasting. SCF iteration arguments and results solve the -original dominance problem for nested mutable state. - -Pull request 1862 is represented as behavior coverage rather than a second -frontend architecture. Seventeen imported programs compare exact QC and ten -exercise loop or dynamic-index structure. After cleanup, the focused evidence is -13 OQ3 tests, 87 staged frontend and target tests, 241 QC translation tests, 121 -QC-to-QCO tests, 97 legacy parser tests, and 91.4 percent substantive -changed-surface line coverage (4,348 of 4,759 lines). +The completed frontend groundwork is retained: the native parser and semantic +analyzer cover the source-language behavior needed by the compiler. The earlier +OQ3 target architecture has been removed in favor of direct QC emission. + +The direct architecture and end-to-end behavior are implemented. Eleven broad +OpenQASM fixtures traverse direct QC, QCO cleanup and optimization, Jeff byte +serialization and deserialization, reconstructed QCO and QC, and Adaptive QIR; +the same fixtures pass `runDefaultPipeline`. Four straight-line fixtures also +reach Base QIR. The corpus includes custom and broadcast gates, arithmetic and +math parameters, nested `if`/`for`, measurement-controlled `while`, mutable bit +state carried by a loop, a dynamically written index resolved during cleanup, +reset, barrier, and mixed positive and negative controls. + +The only new downstream production correction is in Jeff-to-QCO: entry points +with observable results now regain their compiler marker without losing those +results. Its native regression is independent of OpenQASM. General runtime +dynamic indexing remains a deliberate limitation of the Jeff path because Jeff +cannot represent the source bounds assertion. The frontend and direct QC target +continue to support and test it; the documentation does not overclaim full-chain +support. All final validation gates passed, including 90.7 percent line coverage +over the substantive frontend and emitter sources. ## Context and Orientation -`mlir/lib/Target/OpenQASM/Frontend.cpp` owns the source manager and returns an -opaque `ParsedProgram`. `OpenQASMLexer.cpp`, `OpenQASMParser.h`, -`OpenQASMSyntax.h`, and `OpenQASMSyntax.cpp` implement tokenization, grammar, -source recovery, and persistent target-independent syntax. -`OpenQASMSemantics.cpp` resolves that syntax into the `TypedProgram` declared in -`mlir/include/mlir/Target/OpenQASM/Frontend.h`. These stages do not depend on an -MLIR context. - -`mlir/lib/Target/OpenQASM/OpenQASM.cpp` emits the typed program using builtin -MLIR plus `arith`, `cf`, `func`, `math`, `memref`, `scf`, `ub`, QC, and OQ3. -Mutable state is held by standard SSA values and explicitly crosses SCF region -boundaries. Dynamic qubit references become structured dispatch over canonical -QC references rather than new loads or qubit-valued selection. - -`mlir/lib/Conversion/OQ3ToQC/OQ3ToQC.cpp` is the target boundary. It validates -and orders reachable custom gates, lowers supported OQ3 gate applications, -reports unsupported target semantics, erases gate symbols, and completes with -OQ3 marked illegal. - -`mlir/lib/Conversion/QCToQCO/QCToQCO.cpp` converts QC reference semantics to QCO -value semantics. Structured operations preserve their classical operands and -results while appending quantum values. Region-local mappings and a separate -terminator phase preserve the latest branch and loop state. - -Tests under `mlir/unittests/Target/OpenQASM` exercise parsing, analysis, OQ3 -emission, QC conversion, source diagnostics, and the imported fixture corpus. -Tests under `mlir/unittests/Dialect/OQ3`, -`mlir/unittests/Dialect/QC/Translation`, and `mlir/unittests/Conversion/QCToQCO` -defend the IR and conversion boundaries. +`mlir/lib/Target/OpenQASM/Frontend.cpp` owns source buffers and orchestrates +parsing. `OpenQASMLexer.cpp`, `OpenQASMParser.h`, `OpenQASMSyntax.h`, and +`OpenQASMSyntax.cpp` implement tokenization, grammar, recovery, and persistent +syntax. `OpenQASMSemantics.cpp` resolves syntax into the `TypedProgram` declared +in `mlir/include/mlir/Target/OpenQASM/Frontend.h`. These files use LLVM support +but do not require an `MLIRContext`. A `TypedProgram` is a compact resolved +representation containing expressions, conditions, declarations, statements, +gate definitions, source locations, and output registers. + +Direct QC construction lives in the private +`mlir/lib/Dialect/QC/Translation/OpenQASMToQCEmitter.cpp`. The reusable gate +metadata lives in `mlir/include/mlir/Target/OpenQASM/GateCatalog.h` and +`mlir/lib/Target/OpenQASM/GateCatalog.cpp`, where semantic analysis and target +emission share one authoritative catalog. + +The stable user-facing translation functions are declared in +`mlir/include/mlir/Dialect/QC/Translation/TranslateQASM3ToQC.h` and implemented +in `mlir/lib/Dialect/QC/Translation/TranslateQASM3ToQC.cpp`. They accept either +an LLVM source manager or source text and return an owning reference to an MLIR +module. `QCProgram::fromQASMString` in `mlir/lib/Compiler/Programs.cpp` calls +this API. The translation source must stay small; a new private emitter beside +it owns all typed-program-to-QC construction. + +QC uses reference-like qubits. QCO is the optimizer dialect and uses linear SSA +values, meaning each quantum operation returns the next value representing its +qubit. QC-to-QCO and QCO-to-QC bridge those models. Jeff is a serializable +exchange representation reached from QCO. QIR is LLVM-based output reached from +QC. The compiler program wrappers in `mlir/include/mlir/Compiler/Programs.h` +provide ownership-safe transitions between these representations. + +`mlir/unittests/programs/qasm_programs.cpp` and its header contain reusable +OpenQASM source fixtures. Translation equivalence tests live in +`mlir/unittests/Dialect/QC/Translation/test_qasm3_translation.cpp`. The complete +public compiler path belongs in +`mlir/unittests/Compiler/test_compiler_pipeline.cpp`. Tests directly attached to +QC-to-QCO, QCO-to-QC, Jeff, and QIR must use their dialect-native builders or +small MLIR strings, not invoke the OpenQASM parser. ## Plan of Work -### Milestone 1: establish the target-neutral boundary - -Keep only source distinctions that QC cannot faithfully represent in OQ3. Move -target lowering to `Conversion/OQ3ToQC`, express it through MLIR dialect -conversion, and mark OQ3 illegal in the successful target. Demonstrate both a -supported gate program and the valid-but-unsupported `pow` boundary. - -### Milestone 2: replace the legacy parser bridge - -Use LLVM source ownership, `StringRef` token spans, `SMLoc` diagnostics, and -bump-allocated transient parser data. Parsing must return persistent syntax and -diagnostics without constructing MLIR. Includes must retain source identity and -lifetime after the caller source manager is destroyed. - -### Milestone 3: implement source semantics and structured state +### Milestone 1: remove the intermediate dialect and establish direct emission + +Delete `mlir/include/mlir/Dialect/OQ3`, `mlir/lib/Dialect/OQ3`, +`mlir/include/mlir/Conversion/OQ3ToQC`, `mlir/lib/Conversion/OQ3ToQC`, and +`mlir/unittests/Dialect/OQ3`. Remove their `add_subdirectory` entries, generated +operation dependencies, tool dialect registrations, unit-test registration, and +link libraries from the adjacent CMake files. Delete `docs/mlir/OQ3.md` and +remove its navigation entries. Do not remove `oq3::frontend` merely because its +name contains `oq3`; it is language code rather than a dialect identifier. + +Move the gate catalog to `mlir/include/mlir/Target/OpenQASM/GateCatalog.h` and +`mlir/lib/Target/OpenQASM/GateCatalog.cpp`, retaining one authoritative table +for language gates, standard-library gates, compatibility aliases, canonical QC +primitives, parameter counts, control counts, target counts, variadic controls, +and inverse aliases. Update semantic includes and namespaces without duplicating +the table. + +Rename the CMake library in `mlir/lib/Target/OpenQASM/CMakeLists.txt` from +`MLIROpenQASMTarget` to `MLIROpenQASMFrontend`. It contains `Frontend.cpp`, the +lexer, syntax, semantics, and `GateCatalog.cpp`, and links only what those +stages use. Remove `mlir/include/mlir/Target/OpenQASM/OpenQASM.h` and the old +emitter source after direct emission has replaced their behavior. + +Add private `mlir/lib/Dialect/QC/Translation/OpenQASMToQCEmitter.h` and +`OpenQASMToQCEmitter.cpp`. The header declares only a translation-internal +function that accepts a resolved `oq3::frontend::TypedProgram` and an +`MLIRContext` and returns `OwningOpRef`. `TranslateQASM3ToQC.cpp` +parses, analyzes, prints collected source diagnostics on failure, invokes this +private function, verifies the returned QC module, and contains no lowering +implementation. + +The emitter reuses standard `arith`, `cf`, `func`, `math`, `memref`, `scf`, and +`ub` operations for classical behavior and emits QC operations directly. Port +only the target logic from OQ3-to-QC: catalog-to-primitive dispatch, implicit +and variadic controls, inverse aliases, the four-parameter `cu` phase behavior, +ordered inverse/positive-control/negative-control modifiers, and recursive +inlining of typed custom-gate bodies. Semantic analysis continues to reject +source-illegal recursion. The emitter preflights reachable custom-gate expansion +cost, target support, modifier operands, and structured custom-gate limitations +before creating each affected application. A `pow @` modifier produces a +source-located error and a null translation result; scalar exponentiation and +the scalar `pow()` function remain supported. + +Acceptance for this milestone is a clean build with no OQ3 dialect or conversion +target and direct QC translation for existing supported sources. Repository +searches for `OQ3Dialect`, OQ3 operation class names, `createOQ3ToQCPass`, and +`MLIROQ3` must be empty. A search for `oq3::frontend` is not an acceptance +failure. + +### Milestone 2: convert target tests to direct behavior + +Refactor `mlir/unittests/Target/OpenQASM/test_openqasm.cpp` so parser tests +inspect parse results, semantic tests inspect `TypedProgram`, and target tests +inspect verified QC or emitted diagnostics. Remove all tests whose only purpose +is OQ3 operation verification. Preserve behavior tests for source ownership, +recovery, includes, scope, initialization, expressions, broadcasting, dynamic +dispatch, control flow, recursion, and cost bounds. + +Add a positive direct-emission test for representative primitive and custom +gates and a negative test proving that a valid `pow @` program parses and +analyzes but `qc::translateQASM3ToQC` returns null with a source-located message +stating that QC power support is unavailable. Add equivalent focused cases for +every other frontend-accepted feature that the emitter rejects. Update +`mlir/unittests/Target/OpenQASM/CMakeLists.txt` to link `MLIROpenQASMFrontend`, +`MLIRQCTranslation`, and only directly used test libraries. + +Keep exact QC equivalence tests in +`mlir/unittests/Dialect/QC/Translation/test_qasm3_translation.cpp`. They compare +canonicalized direct translation against QC builder references and should cover +catalog aliases, controls, inverses, custom-gate expansion, expressions, +broadcasting, measurement, and structured control flow where a stable reference +is practical. + +### Milestone 3: build the full compiler-chain corpus + +In `mlir/unittests/programs/qasm_programs.h` and `qasm_programs.cpp`, expose a +small shared corpus whose descriptors contain only a stable name and source. +Keep the sources themselves as the existing named constants where useful. Do not +attach expected-failure, Jeff-support, profile, or workaround flags. Create +explicit positive source groups in the consuming tests: a broad +Adaptive-plus-Jeff group and a straight-line subset that must additionally pass +Base QIR. Include nested `if`, `for`, and `while`; loop-carried mutable scalar +and bit state; dynamic indexing; measurement-controlled flow; broadcast +primitive and custom gates; custom-gate expansion; inverse and positive and +negative controls; arithmetic and math gate parameters; reset; barrier; and +observable outputs. + +Add a parameterized integration suite to +`mlir/unittests/Compiler/test_compiler_pipeline.cpp`. For every source in the +Adaptive-plus-Jeff group, use the public APIs in exactly this order: + + QCProgram::fromQASMString + QCProgram::intoQCO + QCOProgram::cleanup + QCOProgram::runPassPipeline("mqt-qco-default") + QCOProgram::cleanup + QCOProgram::intoJeff + JeffProgram::cleanup + JeffProgram::toBytes + JeffProgram::fromBytes + JeffProgram::cleanup + JeffProgram::intoQCO + QCOProgram::cleanup + QCOProgram::intoQC + QCProgram::cleanup + QCProgram::intoQIR(QIRProfile::Adaptive) + QIRProgram::llvmIR and QIRProgram::toBitcode + +Retain copies at the necessary ownership boundaries so the test can identify the +exact failing stage. Require every optional result to be present, every cleanup +or pipeline call to succeed, the LLVM IR to be nonempty, and bitcode to begin +with the LLVM bitcode magic. For the straight-line subset, repeat the QIR tail +with `QIRProfile::Base` as well as Adaptive. + +Add a separate parameterized call to `runDefaultPipeline` for every broad corpus +source, requesting Adaptive QIR and checking its LLVM IR and bitcode. This +proves the production default path independently; it does not replace the +explicit chain because the default pipeline intentionally omits Jeff. Test +failure messages must include the source name and stage. + +### Milestone 4: isolate and fix demonstrated downstream defects + +Run the full-chain corpus against the current conversion implementations. For +each failure, save the smallest native QC, QCO, or Jeff MLIR that reproduces the +stage failure. Add that reduced program to the appropriate conversion unit test +using existing program builders when they express it cleanly, otherwise a small +MLIR string. Do not make these unit tests parse OpenQASM. + +Inspect the branch diff in `mlir/lib/Conversion/QCToQCO/QCToQCO.cpp` hunk by +hunk. Retain a change only when a reduced regression proves that it is needed, +and simplify it to the smallest dialect-native correction. Pay particular +attention to SCF operands and results, region arguments, `scf.yield`, +`scf.condition`, measurement results, and the distinction between classical +state and linear quantum state. Apply the same evidence rule to +`mlir/lib/Conversion/QCOToQC`, Jeff conversions, and QC-to-QIR. Do not edit a +downstream conversion merely because it was named in this plan. + +After each fix, run its focused native conversion test first, then the failing +full-chain fixture, then the entire corpus. If a feature cannot be represented +faithfully by the current pipeline, move its failure to the direct QC emitter +only when the limitation is intrinsic to accepted compiler dialects rather than +a correctable conversion bug, and document the diagnostic and matrix status. +Never add a fixture flag that makes the integration test accept failure. + +### Milestone 5: minimize, document, and validate + +Inspect the effective diff against `origin/main`, including all commits and +unstaged files. Delete obsolete OQ3 concepts, duplicate gate dispatch, +superseded tests, stale target names, temporary compatibility wrappers, +iteration comments, and downstream conversion hunks lacking native regression +evidence. Keep `TranslateQASM3ToQC.cpp` small and keep production dependencies +pointing in one direction: QC translation depends on the OpenQASM frontend, not +the reverse. + +Create `docs/mlir/OpenQASM.md` and link it from `docs/mlir/index.md` and the +relevant translation overview. It contains two maintained feature tables but +does not duplicate the language specification. The first covers parser and +semantic behavior. The second has columns for feature, Parse, Semantics, QC, +Full Adaptive plus Jeff, Base, restriction or rejection reason, and the +representative test. Use precise statuses such as supported, recognized and +rejected semantically, or accepted by the frontend and rejected by QC. Mark +structured fixtures Adaptive-only and record Base support only for the tested +straight-line subset. List `pow @` as parsed and semantically valid but rejected +by QC. Update `CHANGELOG.md` to describe direct OpenQASM import without an OQ3 +dialect claim. + +Run formatting, all affected unit binaries, the legacy parser regression, +warning-as-error documentation, coverage, and repository lint after cleanup. +Record the final evidence in this plan's progress, discoveries, outcomes, and +artifacts sections. -Resolve all names, types, scopes, initialization, gates, indices, assignments, -and conditions in one semantic pass. Emit `if`, `for`, and `while` as SCF with -minimal carried state. Cover ascending, descending, empty, dynamic, zero-step, -and integer-boundary ranges and nested updates to outer scalar and bit state. - -### Milestone 4: close specification and target gaps +## Concrete Steps -Add exact version and include behavior, strict identifiers and numeric forms, -OpenQASM 2 compatibility, custom gates, broadcasting, dynamic canonical-qubit -dispatch, physical addressing checks, recursion and expansion budgets, and -precise target errors for unsupported modifiers. Update QC-to-QCO wherever the -new valid structured QC exposes a downstream value-semantics gap. +Run all commands from the repository root. Preserve unrelated changes and +inspect status before editing: -### Milestone 5: prove and clean the complete result + git status --short --branch + git diff --stat origin/main...HEAD + git diff --stat origin/main -Port the useful pull request 1862 fixtures, add behavior-driven tests at each -trust boundary, run changed-surface coverage, and obtain fresh read-only review. -Remove experimental scaffolding, duplicate concepts, stale names, repetitive -plan history, and comments that describe iteration rather than the final design. -Repeat all affected validation after cleanup. +Configure a clean debug build using an installed MLIR 22.1 CMake package.

Do not record a -machine-specific MLIR path in this plan. +For coverage, use the coverage preset, delete only ignored stale coverage +counters, and run the affected binaries sequentially because concurrent runs can +corrupt shared counters. Report line and branch coverage for +`mlir/lib/Target/OpenQASM` and the private direct emitter. Keep generated output +under `build/coverage` and record the final command and summary here when run. ## Validation and Acceptance -Parsing is accepted when tokens and diagnostics retain source identity, includes -remain owned, multiple recoverable errors are returned as data, and no parser or -analyzer operation requires MLIR. Semantic analysis is accepted when valid -programs produce a typed program and invalid programs fail with source-located -diagnostics before emission. - -Emission is accepted when ordinary programs verify, source loops produce valid -SCF, nested mutable state crosses regions through explicit arguments and -results, and dynamic qubit operations use canonical references with bounded -structured dispatch. The valid `pow` program must still verify as OQ3. - -OQ3-to-QC is accepted when supported programs produce verified QC with no OQ3 -operations, while unsupported power or structured custom-gate modifiers fail -with target-specific diagnostics. Reachable recursion and excessive expansion -must fail; unreachable definitions must not affect valid programs. - -QC-to-QCO is accepted when structured branches and loops preserve original -classical results and final quantum values independent of conversion traversal -order. Dynamic measurement dispatch must remain valid through this conversion. - -Final acceptance requires all focused binaries and legacy parser tests to pass, -all 27 imported fixtures to assert behavior, documentation to build with -warnings as errors, repository hooks to pass over every live file, -`git diff --check origin/main` to succeed, and changed-surface substantive line -coverage to remain at least 90 percent. +The frontend is accepted when parsing and semantic analysis require no MLIR +context, included buffers retain accurate source locations, valid programs +produce a resolved typed program, and invalid source returns collected +diagnostics at the owning stage. + +Direct emission is accepted when supported programs return verified modules +containing QC and standard MLIR dialects only. Primitive aliases, custom gates, +broadcasting, controls, inverse and negative controls, expressions, dynamic +indices, measurements, reset, barrier, and structured control flow must retain +their tested behavior. A valid `pow @` program must parse and analyze, then fail +QC translation with a precise source-located message and no fallback IR. + +The complete compiler is accepted when every broad corpus fixture passes the +explicit public API chain through optimized QCO, Jeff byte serialization and +deserialization, reconstructed QC, Adaptive QIR, LLVM IR, and bitcode. Every +fixture must also pass `runDefaultPipeline` to Adaptive QIR. Every source in the +straight-line subset must additionally produce Base QIR. Structured sources are +not required to produce Base QIR and must not be encoded as expected failures in +the corpus. + +Every retained downstream conversion change is accepted only with a focused +parser-independent native-IR regression that fails without the change and passes +with it. The related full-chain OpenQASM fixture must also pass. No conversion +test may link the OpenQASM frontend solely to construct its input. + +The architecture is accepted when there is no OQ3 dialect, OQ3 operation, +OQ3-to-QC pass, generated OQ3 target, tool registration, or dialect test. The +`oq3::frontend` namespace may remain. There is one gate catalog, the frontend +library is named `MLIROpenQASMFrontend`, the public translation adapter is +small, and direct emission is private to QC translation. + +Final acceptance requires all affected and full MLIR unit tests, the legacy +parser regression, documentation with warnings treated as errors, coverage of at +least 90 percent of substantive newly added frontend/emitter lines, +`uvx nox -s lint`, and `git diff --check origin/main` to pass. The final diff +must contain no build output, generated documentation, temporary workaround, or +unjustified production conversion change. ## Idempotence and Recovery -Configuration, builds, tests, documentation, lint, and coverage commands are -repeatable and write only ignored output. Coverage binaries must be run -sequentially after removing stale counters. +Configuration, compilation, unit tests, documentation, lint, and diff checks are +repeatable and write only to ignored build directories. If CMake retains deleted +OQ3 targets, remove the ignored `build` and `docs/_build` directories and +configure again; do not add source-tree cleanup workarounds. -Do not restore the stream bridge or introduce a parser-to-emitter fallback if a -syntax family fails. Preserve the failing source test and repair the staged -frontend at the owning layer. Preserve unrelated user changes, do not modify -another task worktree, and require a clean task worktree before any rebase. +Make the architecture transition in coherent local commits when useful, but do +not push. Before removing an old source, ensure its required direct-emission +behavior has moved into the private emitter and its tests pass. If a downstream +fixture fails, preserve the failing source, reduce it to native IR, and repair +the owning conversion instead of introducing a parser-side special case. -This plan does not authorize pushing, changing pull request state, resolving -review threads, or publishing comments. Those actions require separate human -authorization. +Never discard unrelated user changes or edit another task worktree. This plan +does not authorize pushing, changing pull request state, resolving review +threads, or publishing comments.

It also contained a stream adapter and no -source path from loop tokens to a loop statement. - -The cleaned implementation produces: - - 13 OQ3 tests passed. - 87 staged frontend and target tests passed. - 241 QC translation tests passed. - 121 QC-to-QCO tests passed. - 97 legacy OpenQASM parser tests passed. - 17 imported programs matched exact QC references. - 10 imported loop or dynamic-index programs passed structural contracts. - 4,348 of 4,759 substantive changed lines were covered (91.4 percent). +The completed groundwork before this revision comprised an LLVM-native staged +frontend, 27 imported behavior fixtures, source control flow and carried state, +and clean focused validation. It also comprised an OQ3 dialect and OQ3-to-QC +pass that this plan now deliberately removes.
