[mlir][vector] Linearization: push 'bit width' logic out of patterns (#136581) [NFC] Vector linearization is a collection of rewrite patterns that reduce the rank of vector operands and results. In https://github.com/llvm/llvm-project/pull/83314 an option to ignore (make 'legal') operations with large inner-most dimensions was added. This current PR is a step towards making that option live outside of upstream MLIR. The motivation is to remove non-core functionality (I would like to use this pass, but would prefer not to deal with 'targetVectorBitWidth` at all). As a follow-up to this PR, I propose that user(s) of the `targetVectorBitWidth` move the relevant code (now in mlir/test/lib/Dialect/Vector/TestVectorTransforms.cpp) to their code bases, and then eventually remove it from upstream. In addition the tests need to split out (I've intentionally not modified the lit tests here, to make it easier to confirm that this is a NFC). I'm happy to help make it easier to do this final step! The approach I've used is to move the logic pertaining to `targetVectorBitWidth` out the patterns, and into the conversion target, which the end user can control outside of core MLIR.
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.
