[Mlir-commits] [mlir] [mlir][xegpu] Remove chunk_size attribute; infer from types (PR #205122)

https://github.com/mshahneo created https://github.com/llvm/llvm-project/pull/205122

The chunk_size attribute on xegpu.load (LoadGatherOp) and xegpu.store (StoreScatterOp) was redundant with the operand/result types: the XeVM lowering never read it, VectorToXeGPU already built these ops with an empty chunk_size, and the op docs noted it could be inferred from the type.

Remove the attribute and infer the chunk size from the value/result and mask types via a computed getChunkSize() op method. The mask carries one element per lane, so the chunk size is the trailing value dimension when the value has more elements than the mask, and 1 otherwise. This keeps the existing op.getChunkSize() call sites working while respecting library layering (no XeGPUUtils dependency from the IR library).

Update the gather/scatter builders, transforms (propagate-layout, sg-to-lane, wg-to-sg, unroll), VectorToXeGPU lowerings, and lit tests. Two invalid.mlir cases that were only invalid because a stated chunk_size contradicted the type are removed; two others are reclassified to the type/shape diagnostic.

Subject: [PATCH] [mlir][xegpu] Remove chunk_size attribute; infer from types

The chunk_size attribute on xegpu.load (LoadGatherOp) and xegpu.store
(StoreScatterOp) was redundant with the operand/result types: the
XeVM lowering never read it, VectorToXeGPU already built these ops with an
empty chunk_size, and the op docs noted it could be inferred from the type.

Remove the attribute and infer the chunk size from the value/result and
mask types via a computed getChunkSize() op method. The mask carries one
element per lane, so the chunk size is the trailing value dimension when
the value has more elements than the mask, and 1 otherwise. This keeps the
existing op.getChunkSize() call sites working while respecting library
layering (no XeGPUUtils dependency from the IR library).

Update the gather/scatter builders, transforms (propagate-layout,
sg-to-lane, wg-to-sg, unroll), VectorToXeGPU lowerings, and lit tests.
Two invalid.mlir cases that were only invalid because a stated chunk_size
contradicted the type are removed; two others are reclassified to the
type/shape diagnostic.
