[mlir][xegpu] Add OptimizeBlockLoads pass. (#165483) This pass rewrites certain xegpu `CreateNd` and `LoadNd` operations that feeds into `vector.transpose` to more optimal form to improve performance. Specifically, low precision (bitwidth < 32) `LoadNd` ops that feeds into transpose ops are rewritten to i32 loads with a valid transpose layout such that later passes can use the load with transpose HW feature to accelerate such load ops. **Update:** Pass is renamed to `OptimizeBlockLoads ` because later we plan to add the array length optimization into this pass as well. This will break down a larger load (like `32x32xf16`) into more DPAS-favorable array length loads (`32x16xf16` with array length = 2). Both these optmizations require rewriting `CreateNd` and `LoadNd` and it makes sense to have a common pass for both.
Welcome to the LLVM project!
This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.
The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.
C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.
Other components include: the libc++ C++ standard library, the LLD linker, and more.
Consult the Getting Started with LLVM page for information on building and running LLVM.
