[Refactor] Move backend-specific GEMM implementations and transforms into backend directories (#2165)
* [Refactor] Move backend-specific GEMM implementations and transforms into backend directories Restructure the codebase so that each backend (cpu, cuda, rocm) owns its GEMM implementations, sparse GEMM implementations, and transform passes under a consistent op/ subdirectory layout. The shared GEMM registry and base classes remain in tileop/ as the platform-agnostic dispatch layer. - Move gemm/gemm_sp registries from backend/ into tileop/ as registry.py - Move CUDA GEMM impls (mma, mma_sm70, wgmma, tcgen05) into backend/cuda/op/gemm/ - Move CUDA sparse GEMM impl into backend/cuda/op/gemm_sp/ - Move CPU GEMM impl (scalar) into backend/cpu/op/gemm/ - Move ROCm GEMM impls (mfma, wmma) into backend/rocm/op/gemm/ - Move CUDA-specific transform passes from src/transform/ into src/backend/cuda/transform/ - Move CUDA runtime sources from src/runtime/ into src/backend/cuda/ - Remove dead backend-importing wrappers from transform/__init__.py - Update phase.py and tests to import CUDA transforms from their canonical location Each backend now has a symmetric op/ directory structure. Adding a new backend no longer requires modifying shared transform or tileop modules. * Refactor Python backend package layout * Remove deprecated intrinsic implementations and related tests for matrix multiplication and element-wise addition. This includes the deletion of files for `benchmark_matmul_intrinsic.py`, `example_tilelang_gemm_fp8_intrinsic.py`, and associated test files, streamlining the codebase by eliminating unused components. * Move CUDA transform passes back to common transform |

[Refactor][Pipeline] Run pipeline rewriting before layout inference and stabilize tiled WS (#2002)
* Refactor optimization pipeline in phase.py to streamline barrier handling
- Consolidated the handling of shared barriers and pipeline planning by removing redundant conditional checks.
- Ensured that `LowerSharedBarrier`, `PipelinePlanning`, and `InjectSoftwarePipeline` are consistently applied, enhancing the clarity and efficiency of the optimization process.
This change improves the maintainability of the code while preserving existing functionality.
* Enhance tile operation handling with instruction annotation and refactor gemm.h
- Added a new `InstructionAnnotation` pass to annotate tile operations with their instruction kind before layout inference, improving the optimization pipeline's ability to reason about instruction mixes.
- Refactored `gemm.h` to move the `allowTcgen5Mma` and `allowWgmma` methods under the private section, enhancing code organization and encapsulation.
These changes improve the clarity and maintainability of the code while preserving existing functionality.
* Enhance multi-version buffer handling and introduce tile-level warp specialization
- Updated `multi_version_buffer_rewriter.cc` to improve read/write access detection for tile operations by analyzing `tl.tileop.region` calls, ensuring accurate buffer access tracking.
- Modified `phase.py` to integrate `ProducerConsumerWarpSpecializedTiled` before layout inference, allowing for high-level tile-op IR transformations that enhance producer/consumer splits.
- Added a new `ProducerConsumerWarpSpecializedTiled` function in `__init__.py` to facilitate tile-level warp specialization, improving the optimization pipeline's efficiency.
These changes enhance the handling of multi-version buffers and optimize the transformation process for tiled operations.
* Enable tiled WS for stage-1 pipelines
* Move Hopper pipeline planning before layout inference
* Run pipeline rewriting before layout inference
* Add pipeline refactor WIP: subtree_modified_ guard, debug prints, and plan
- inject_pipeline.cc: guard reads/writes recalculation with subtree_modified_
flag to prevent local.var buffer promotion to kernel parameters
- phase.py: add temporary debug prints after PipelinePlanning and
InjectSoftwarePipeline (to be removed during CI fix work)
- example_group_per_split_token_cast_to_fp8.py: add disable_cache for debugging
- docs/plan.md: implementation plan for fixing CI test failures
- draft.md: original design draft

* Remove debug artifacts: prints in phase.py, disable_cache in example
- Remove print("After PipelinePlanning"), print(mod),
print("After InjectSoftwarePipeline"), print(mod) from
LowerAndLegalize in tilelang/engine/phase.py
- Remove tilelang.disable_cache() from
examples/cast/example_group_per_split_token_cast_to_fp8.py

* Fix LayoutInference crash on multi-versioned pipeline buffers
After InjectSoftwarePipeline, multi-versioned buffers share the same
data Var as the original but have an extra leading dimension (num_stages).
LayoutInference's alias propagation and annotation handling tried to
Reshape layouts between these buffers, which failed because the total
element counts differ.
Guard three Reshape call sites in layout_inference.cc to skip sibling
buffers whose total storage size is incompatible with the source layout.
This lets multi-versioned buffers get their own layout inference instead
of inheriting an incompatible layout from the original buffer.
Fixes compilation failures in dequantize_gemm, GDN, and other kernels
that use software pipelining with shared memory buffers.

* Strip pipeline annotations on WS fallback for TMA kernels
When ProducerConsumerWarpSpecializedTiled identifies a TMA kernel as a
warp-specialization candidate but the tiled rewriter cannot handle it
(e.g., conditional loop bodies like sparse block masks), the fallback
previously returned the original function with num_stages annotations
intact. PipelinePlanning and InjectSoftwarePipeline would then generate
non-WS TMA pipeline code with broken barrier phase tracking for
conditional pipeline bodies (barrier waits outside conditionals cause
deadlocks when the condition is false).
Fix: on WS fallback, strip num_stages annotations from pipeline loops
so that the pipeline passes skip the function. The kernel runs
unpipelined but correctly.
Fixes CUDA_ERROR_LAUNCH_FAILED in blocksparse_gemm and related TMA
kernels with conditional loop bodies.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Add guarded phase-counter support to tiled WS pass
Port PhaseCounter and StageExprReplacer from the legacy
ProducerConsumerWarpSpecialized pass into the tiled WS pass to handle
conditional loop bodies (e.g., sparse block masks).
When the pipeline loop body is wrapped in an IfThenElse without else:
1. Unwrap the condition before classifying statements
2. Create separate producer/consumer PhaseCounters (local int32 buffers)
3. Use counter-based stage/parity expressions instead of loop-variable
4. Wrap producer and consumer bodies in the original condition
5. Increment counters at end of each guarded iteration
6. Rewrite shared-buffer stage indices via StageExprReplacer
This ensures barrier parity stays correct when iterations are
conditionally skipped, fixing CUDA_ERROR_LAUNCH_FAILED in
blocksparse_gemm and related TMA kernels with conditional execution.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Add GemmSPNode support to pipeline planning and injection
Add GemmSPNode handling to:
- inject_pipeline.cc AddReadsWritesForTileOp: model A, E, B as reads
and C as write (E is the sparse metadata buffer)
- pipeline_planning.cc: same access model for dependency analysis
This makes sparse GEMM visible to the pipeline machinery for correct
stage assignment and buffer multi-versioning. However, the tile-op's
consumer-side buffer accesses still don't get stage-indexed because
the pipeline body rewriter can't rewrite high-level tile-op Call
arguments (an architectural limitation of running InjectSoftwarePipeline
before LowerTileOp).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix GemmSPNode::Lower to use MakeAccessPtrFromRegion
Replace whole-buffer access_ptr(1) calls with MakeAccessPtrFromRegion
for A, B, C, and E buffers in sparse GEMM lowering. This preserves
stage-specific region offsets from pipeline multi-versioning, matching
the dense GemmNode::Lower pattern.
CUDA output now shows correct stage-indexed consumer accesses:
gemm_sp_ss(..., (k%3)*8192, (k%3)*8192+27648, C_local, (k%3)*2048+49152)
instead of always using stage-0 offsets.
Note: gemm_sp still produces incorrect results because the kernel needs
warp specialization but TiledWSCandidate::Check doesn't recognize it
as a TMA candidate. The non-WS pipeline path generates structurally
different code from the reference WS path.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix gemm_sp and seer_attention regressions
Three changes in producer_consumer_ws_tiled.cc:
1. Require num_stages >= 2 for WS candidacy (was >= 1). Single-stage
kernels like seer_attention don't need WS and the transformation
produces incorrect results for them.
2. Add HasTmaPipeline() check to detect TMA kernels with pipeline
annotations that are rejected by the full WS candidate check (e.g.,
kernels with manual layout annotations like gemm_sp).
3. Strip num_stages annotations for rejected TMA pipeline kernels to
prevent InjectSoftwarePipeline from generating broken non-WS TMA
pipeline code.
One change in gemm_sp.cc:
- Use MakeAccessPtrFromRegion for A, B, C, E buffer access pointers
instead of whole-buffer access_ptr. This preserves stage-specific
region offsets from pipeline multi-versioning.

* Fix WS conditional body unwrapping for complex loop bodies
Only unwrap IfThenElse wrapper when the then-branch is a simple flat
sequence of tile-op Evaluate calls. Skip unwrapping for complex bodies
with LetStmt, For, or other control flow that could break variable
scoping when split into producer/consumer for WS.
Fixes variable-used-before-definition error in
blocksparse_attention sparse_gqa_decode_varlen_indice, which has a
conditional loop body containing LetStmt bindings.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Revert num_stages >= 2 to >= 1 for WS candidacy
The >= 2 threshold broke test_num_stages_one_pure_tma_keeps_auto_warp_specialize.
Pure TMA kernels with num_stages=1 should still be WS candidates.
The seer_attention issue (num_stages=1 with manual layout) is handled
by the has_manual_layout_ check, not the num_stages threshold.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Propagate manual layouts onto MVB-expanded buffers via Layout::Expand
When LayoutInference encounters an MVB-expanded buffer (with leading
stage dimensions) whose trailing dimensions match the original layout,
use Layout::Expand to propagate the manual layout instead of rejecting
or skipping the buffer. Applied to all 3 layout propagation paths:
annotated layout map, alias propagation, and finalization.
Also remove the blanket !has_manual_layout_ WS candidate rejection
since manual layouts now survive onto versioned shared buffers via
Layout::Expand.
Fixes test_sparse_ws_regular_metadata_copy_stays_in_producer.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Extend conditional body unwrapping for LetStmt chains and restore
has_manual_layout_ guard
1. LetStmt chain peeling: when IfThenElse then_case starts with
LetStmt bindings, peel them and append to let_bindings before
checking the simple-body guard. This allows WS for conditional
bodies with variable definitions (e.g., sparse attention patterns).
2. Restore !has_manual_layout_ in WS candidacy check: removing it
caused dequant_groupedgemm_bf16_mxfp4_hopper to fail because
MXFP4 layouts don't survive MVB expansion. The Layout::Expand fix
handles sparse metadata layouts but not all manual layout types.
3. Layout::Expand propagation (from Round 6) remains in place for
future use when MVB learns to handle all manual layout types.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Remove is_simple_body guard from conditional WS unwrapping
The simple-body guard only accepted flat Evaluate sequences inside
IfThenElse, blocking legitimate WS for complex conditional bodies
like sparse flash attention (T.clear, T.reduce_max, T.gemm inside
the guard). The LetStmt peeling already handles variable scoping.
Fixes test_pure_tma_consumer_local_init_does_not_leak_into_producer
and test_sparse_ws_regular_metadata_copy_stays_in_producer.
The remaining test_mixed_tma_cp_async_shared_stage_barriers failure
is a pre-existing issue on the original branch: the tiled WS pass
produces SIMT copies instead of cp.async because LowerPTXAsyncCopy
is not in the pass pipeline (the comment at phase.py:308 says it
runs earlier but no actual call exists on either branch or reference).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Preserve pipeline context for WS producer cp.async injection
Wrap the WS producer loop body in a kPipelineContextNumStages AttrStmt
so that LowerTileOp's pipelined_depth_ is > 0 when processing SIMT
producer copies. This enables InjectPTXAsyncCopy to generate cp.async
for global-to-shared copies in the WS producer branch.
Without this, the WS rewriter strips all pipeline annotations from
the rewritten loops, causing LowerTileOp to skip cp.async injection
for SIMT producers. The consumer loop stays annotation-free since it
doesn't need cp.async.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix mixed barrier protocol, consumer-init sinking, restore manual-layout guard
1. Mixed TMA+cp.async barrier: use ptx_cp_async_barrier_noinc for
forward barrier arrival in mixed producer groups, matching the
reference producer_consumer_ws.cc protocol.
2. Consumer-only pre-loop init sinking: in ReplacePipelineLoopInStmt,
guard pre-loop siblings as consumer-only when they're not classified
as producer (TMA/SIMT/cp.async). Fragment init (T.fill, T.clear)
and local buffer init are placed in the consumer branch instead of
the shared prelude.
3. Restored blanket has_manual_layout_ guard: the dtype-based heuristic
to distinguish sparse metadata from MXFP4 layouts doesn't work
because both use uint8. Dequant_groupedgemm_bf16_mxfp4_hopper
requires the guard to prevent broken WS.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Narrow consumer-init sinking, targeted manual-layout check, per-group barrier
1. Consumer-init sinking: only sink pre-loop stmts that are FillNode
writing to fragment/local buffers. Keep block_mask setup and shared
state in the shared prelude.
2. Manual-layout: attempt targeted check that only rejects when TMA
copy destinations match layout_map entries. Collect layout_map vars
and compare against TMA copy destinations.
3. Per-group cp.async barrier: use group-level cp.async flag (single
group for now) instead of function-wide boolean.
The 3 WS issue tests still fail because the layout_map annotation
parsing falls through to the conservative rejection path.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix layout_map parsing with Var→Buffer mapping for manual-layout check
The layout_map annotation uses Map<Var, Layout> before LayoutInference
(not Map<Buffer, Layout>). Parse as Map<ObjectRef, ObjectRef> and
handle both key types: Buffer (post-inference) and Var (pre-inference).
For Var keys, look up the corresponding alloc_buffer by data Var match.
Compare collected manual-layout buffers against pipeline copy
destinations: reject only when a manually-laid-out buffer is also
a producer copy target (TMA/SIMT/cp.async) inside the pipeline.
This allows sparse metadata (E_shared, SIMT-copied) onto the WS path
while rejecting dequant MXFP4 (B_shared, SIMT-copied with swizzle).
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix SEGFAULT in manual-layout check, use DetectSwizzleMode
1. Fixed SEGFAULT: removed dangling layout_map_layouts_ vector that
was never populated, causing OOB access. Now stores Buffer+Layout
pairs in layout_map_entries_.
2. Use DetectSwizzleMode to distinguish swizzled layouts (MXFP4,
incompatible with MVB) from non-swizzled (sparse metadata, safe).
Swizzled layouts reject WS candidacy; non-swizzled layouts allow it.
3. Removed debug LOG(WARNING) from hot path.
4. Parse layout_map annotation keys as both Buffer and Var (via
Map<ObjectRef, ObjectRef>), resolving Var keys to alloc_buffers.
Results: sparse metadata WS test PASSES, dequant PASSES (protected).
Down to 2 failures: mixed barrier pattern + consumer init sinking.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Simplify consumer-init sinking to Evaluate-only classification
Sink pre-loop Evaluate nodes classified as kConsumer into consumer
branch. Keep For loops (block_mask setup), producer copies, and other
control flow in the shared prelude. This is simpler and safer than
the FillNode scope check approach.
The test_pure_tma_consumer_local_init test still fails because the
T.fill statements are at a different structural level than the
SeqStmt where the pipeline loop lives. Fixing this requires deeper
IR structure analysis.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Sink consumer-only pre-loop init into WS consumer branch
Extract consumer-only pre-loop Evaluate statements (T.fill on
fragments) from the shared prelude and prepend them to the consumer
branch inside the WS if/else structure. This ensures fragment init
like acc_o, logsum, scores_max appears only in the consumer branch,
not in the shared prelude or producer branch.
Uses a two-pass approach: first ReplacePipelineLoopInStmt extracts
consumer-only stmts into extracted_consumer_init_, then the WS body
is rebuilt with the extracted stmts prepended to the consumer branch.
Fixes test_pure_tma_consumer_local_init_does_not_leak_into_producer.

- Extracted the global stride validation logic into a new static method `CheckGlobalStrides` for better readability and reusability.
- Updated `CheckBulkLoad` and `CheckBulkStore` methods to utilize the new stride checking function, improving code clarity and maintainability.
- Enhanced documentation for the new method to clarify its purpose and requirements.
* Remove redundant copy direction notes from documentation in `copy.h` for stride checks. This simplifies the comments while maintaining clarity on TMA requirements.
* refactor
* layout related fix
* refactor mbarrier with software pipeline.
* remove legacy pass
* Enhance TMA barrier handling and merging logic
- Updated `CopyToTmaCopyRewriter` to conditionally emit arrive barriers based on the last TMA copy.
- Refactored barrier creation to allow merging of TMA barriers when conditions are met, reducing the number of barriers needed.
- Adjusted consumer and producer logic to accommodate merged barriers, ensuring correct synchronization across TMA copies.
- Improved documentation and comments for clarity on the new barrier merging behavior.
* Update example_mhc_post.py to disable main execution and add test function call
- Commented out the main function call in `example_mhc_post.py`.
- Added a call to `tilelang.disable_cache()` and a new `test(n=4096, h=2560)` function for testing purposes.
* Enhance pipeline barrier handling and TMA copy detection
- Updated `RewritePipelineTmaBarriers` to accept additional parameters for loop variable and stage count, improving barrier synchronization.
- Modified `HandleTileOp` to ensure only user-defined T.copy patterns are marked for pipeline barriers, preventing interference with T.tma_copy.
- Adjusted test cases to enforce specific CUDA compute version requirements for better compatibility and consistency.
* lint fix
* Enhance convolution example and TMA handling
- Added kernel source printing in `example_convolution.py` for debugging.
- Disabled the main function call and invoked `run_regression_perf()` to streamline execution.
- Introduced `MakeTmaLeaderCondition` function in `copy.cc` to improve TMA leader-thread condition handling.
- Updated `LowerBulkCopy` and `LowerBulkCopy1D` methods to utilize the new TMA leader condition for better thread management.
- Enhanced `Conv2DIm2ColOpNode` to support barrier annotations, improving synchronization in TMA operations.
* enhance
* Remove example_dequant_groupedgemm_bf16_mxfp4_hopper.py and clean up phase.py by removing unnecessary whitespace. Enhance TMA handling in producer_consumer_ws_tiled.cc to improve barrier synchronization and streamline TMA copy operations.
* fix
* fix
* Eliminate MVB(barrier_only=true) late fixup from OptimizeForTarget
Move pipeline barrier ownership into InjectSoftwarePipeline: create
pipeline_mbar[num_stages] at final expanded size instead of
pipeline_mbar[1] that required late MVB expansion.
Key changes:
- RewritePipelineTmaBarriers creates barriers at num_stages size
- Barrier indices use FloorMod(loop_var - loop_min, num_stages)
- barrier_init has num_stages entries (one per slot, arrive_count=1)
- CopyToTmaCopyRewriter accepts PrimExpr barrier_id (was int)
- phase.py: remove MVB(barrier_only=True), unify both paths under
PlanAndUpdateBufferAllocationLocation
- Fix pre-existing test expectation for tma_copies annotation

* Fix Codex review issues: num_stages=1 regression, im2col pipeline barriers, test fixes
1. Fix num_stages=1 regression: use tl_pipelined_num_stages annotation
for barrier sizing instead of max_stage+1. Gate barrier creation on
pipeline_depth > 1 so num_stages=1 kernels don't get multi-versioned
pipeline barriers.
2. Extend RewritePipelineTmaBarriers to handle c2d_im2col: annotate
im2col calls with pipeline barrier in CopyToTmaCopyRewriter. Add
im2col TMA recognition to PipelinePlanning. Fix im2col Lower() to
respect emit_arrive annotation from pipeline barriers.
3. Fix test_simple_pipeline: use annotation-checking approach instead of
structural equality with hardcoded tma_copies annotation that fails
on non-Hopper targets.
4. Remove dead kPipelineMVBStageExpr/kPipelineMVBParityExpr/
kPipelineMVBContextNumStages emission from inject_pipeline.cc since
pipeline barriers are now created at final size.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix depth-1 barrier ownership, add regression tests, remove dead kPipelineMVB*
1. Fix depth-1 ownership gap: always create shared pipeline barrier for
TMA copies even when pipeline_depth=1. This prevents LowerTileOp from
allocating separate per-copy internal barriers, keeping num_stages=1
kernels at pipeline_mbar[1] (single slot).
2. Add checked-in lowering regression tests:
- non-WS num_stages=3 TMA GEMM → asserts pipeline_mbar[3], no fallback
- non-WS num_stages=1 TMA GEMM → asserts pipeline_mbar[1], no multi-slot
- non-WS num_stages=3 im2col → asserts pipeline_mbar[3] feeds tma_load_im2col
3. Remove dead kPipelineMVB* definitions from pipeline_utils.h and
consumption code from multi_version_buffer_rewriter.cc (stacks,
explicit parity/version index logic, attr stripping).

* Fix GemmWMMA.lower() signature and autotuner cache backwards compatibility
[P1] Add missing mbar_phase_expr parameter to GemmWMMA.lower() to match
the interface expected by GemmPy.lower() dispatch. Without this, any
RDNA kernel using the WMMA path would fail with TypeError.
[P2] Make out_idx.json loading optional in autotuner load_from_disk().
Older cache directories don't have this file; fallback to
compile_args.out_idx when the file is absent.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Add .humanize to gitignore
* Fix HIP swizzle codegen and CPU scalar GEMM region handling
[P2] Update codegen_hip.cc to parse tvm_tuple(device_func, panel_size)
format for threadblock_swizzle_pattern, matching the annotation format
now emitted by T.use_swizzle(). Previously expected StringImmNode which
would ICHECK-fail.
[P2] Fix gemm_scalar.py: clear only the output tile region (not the
whole buffer), and use the last two dimensions from regions to handle
rank>2 buffers with leading singleton dimensions.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Fix HIP codegen to parse tvm_tuple swizzle annotation format
Update codegen_hip.cc threadblock_swizzle_pattern handler to parse
tvm_tuple(device_func, panel_size) format, matching CUDA and cutedsl
codegens. Previously expected StringImmNode which ICHECK-fails with
the current annotation format.

* Restore kPipelineMVB* annotations — still needed by WS tiled full MVB
The kPipelineMVBStageExpr/ParityExpr/ContextNumStages annotations and
their MVB consumption code cannot be removed: they are emitted by
EmitImpl for ALL pipelines and consumed by the full MVB call inside
ProducerConsumerWarpSpecializedTiled. Removing them broke non-TMA
pipeline kernels like mhc_post that go through the WS path.
Restores: annotation emission in inject_pipeline.cc, constant
definitions in pipeline_utils.h, and consumption code in
multi_version_buffer_rewriter.cc.
Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
* Unify barrier multi-versioning in InjectSoftwarePipeline (Direction A)
Move all pipeline barrier multi-versioning into InjectSoftwarePipeline
via ExpandPipelineBarriers, eliminating the need for late
MVB(barrier_only=true) in OptimizeForTarget.
ExpandPipelineBarriers runs before BuildPipeline and handles:
- ISP-created pipeline_mbar (for non-WS TMA pipelines)
- User-written T.alloc_barrier (for manual WS pipelines like softpipe)
Key design: only barriers with explicit ptx_arrive_barrier calls OR
ISP-created local barriers are expanded. Barriers whose arrival is
managed internally by tile-ops (e.g., tcgen05 MMA arrive) are left
unchanged. This distinguishes pipeline sync barriers from hardware-
managed barriers.
Buffer expansion: barrier[N] -> barrier[N * num_stages]
Index rewriting: barrier[idx] -> barrier[stage_expr * N + idx]
Parity rewriting: user_parity -> (iteration_block + offset) % 2
barrier_init replication: [c0,c1] -> [c0,c1,c0,c1] for num_stages=2
Expanded buffers propagate to outer blocks via pending_buffer_remap_.
barrier_init annotations are replicated in VisitStmt_(BlockNode).
