[Refactor] Extract per-task adstack codegen state and helpers from TaskCodeGenLLVM into TaskCodeGenLLVMAdStack by duburcqa · Pull Request #612 · Genesis-Embodied-AI/quadrants

[AutoDiff] Stage 1.1: recognize MaxOverRange specs reducible by a parallel max-reducer dispatch (option D)

[AutoDiff] Stage 1.2: SPIR-V max-reducer shader (option D); body bytecode interpreter for kConst/kBoundVariable/kExternalTensorRead/kAdd/kSub/kMul/kMax

committed

[AutoDiff] Stage 1.3: LLVM runtime function for the option-D max reducer (single-thread serial walk over body bytecode)

committed

[AutoDiff] Stage 1.4a: AdStackCache max-reducer cache methods + body bytecode encoder (encode_max_reducer_body_bytecode)

committed

[AutoDiff] Stage 1.6: substitute_precomputed_max_over_range helper (replaces captured MaxOverRange nodes with Const after reducer dispatch)

committed

[AutoDiff] Stage 1.4b: GfxRuntime::dispatch_max_reducers + adstack_max_reducer_launch.cpp (cmdlist + buffer binding for the option-D max reducer)
