[mlir][xegpu] Add layout based SIMT distribution support for `vector.extract/insert_strided_slice` (#168626) This PR adds general SIMT distribution support for `vector.extract/insert_strided_slice`. Currently vector distribution already have support for these operations but have restrictions to avoid requiring layouts during distribution logic. For example, `extract_stride_slice` require that distributed dimension is fully extracted. However, more complex cases may require extracting partially from distributed dimension (eg. 8x16xf16 extraction from 8x32xf16). These types of cases need the layouts to reason about how the data is spread across SIMT lanes. Currently, we don't have layout access in vector distribution so these new patterns are place in XeGPU side. They have higher pattern benefit so that they will be tried first before trying regular vector distribution based patterns.
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.
