Head commit for run: ec3171ab7a4c06fff4e9c1e441d28ef4e9a5831b / Tianqi Chen <[email protected]> [REFACTOR][TIR] Tie AnnotateDeviceRegions/SplitHostDevice/LowerDeviceKernelLaunch together (#19605) ## Summary These three passes are logically a single host/device split step; having intermediaries between them obscures the model and blocks folding them into one pass. This PR moves each intermediary to the position its actual ordering constraint allows, so that `AnnotateDeviceRegions`, `SplitHostDevice`, and `LowerDeviceKernelLaunch` run consecutively in every pipeline. ## Rationale - `MergeSharedMemoryAllocations` moves **before** `AnnotateDeviceRegions` (the only legal position: `LowerDeviceKernelLaunch` requires at most one dyn-shmem allocation per kernel, so Merge cannot move past Lower). - `MakePackedAPI` moves **after** `LowerDeviceKernelLaunch` (Lower's `kCallingConv = kDeviceKernelLaunch` flag causes `MakePackedAPI` to correctly skip device kernels; the host body's lowered `tvm_call_packed` is transparent to `MakePackedAPI`'s subroutine rewriter). - `FP8StorageLegalize` / `BF16StorageLegalize` move **after** `MakePackedAPI` (their `buffer_map.size()==0` ICHECK requires `MakePackedAPI` to have cleared the map). Prereq for Phase 2: collapsing the three consecutive passes into a single `tirx.transform.SplitHostDevice` with three commented regions. ## Test plan - [x] tests/python/tirx-transform/ target-pass unit tests (25 pass) - [x] tests/python/s_tir/transform/test_merge_dynamic_shared_memory_allocations.py (5 pass) - [x] tests/python/tirx-transform/test_tir_transform_fp8_legalize.py / test_tir_transform_bf16_legalize.py (13 pass) - [x] tests/python/codegen/test_target_codegen_c_host.py / test_target_codegen_device.py (6 pass including test_subroutine_call — verifies Risk #2) - [x] pre-commit run --all-files clean - [ ] CI: lint / Windows / MacOS Report URL: https://github.com/apache/tvm/actions/runs/26486566795 With regards, GitHub Actions via GitBox --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
