This is the first of a series of PRs that together implement support in IREE for XOR swizzling through the SwizzleHintOp. There are four PRs that need to be merged: 1) Allow rank > 1 swizzle hint op operands and add a pass to flatten swizzle hint allocs. 2) Add patterns which can fold reshapes and `extract_slice` ops into empty ops through swizzle hint ops. 3) Add swizzle hint attribute to be set in `lowering_config` and consumed in `GPUPromoteMatmulOperandsPass`. 4) Update `LLVMGPUSelectLoweringStrategy` Pass to set xor swizzles for MXFP4 GEMMs. This is PR 1, which does three things: - Loosens the restriction on SwizzleHintOp inputs needing to be a Shaped type of rank 1. We do this because things are a lot simpler during tiling when you can fold arbitrary shapes into the swizzle hint op and then flatten later. - Introduces a pass to flatten allocs associated to `SwizzleHintOps`. - Moves the verification of flatness of swizzle hint ops to the `ResolveSwizzleHintOps` pass, prior to removal. --------- Signed-off-by: Muzammiluddin Syed <muzasyed@amd.com> Signed-off-by: Keshav Vinayak Jha <keshavvinayakjha@gmail.com>
