[IR] Allow llvm.experimental.memset.pattern to take any sized type as the pattern argument (#132026) I initially thought starting with a more narrow definition and later expanding would make more sense. But as pointed out in review for PR #129220, this restriction is generating additional unnecessary work. This patch alters the intrinsic to accept patterns of any type. Future patches will update LoopIdiomRecognize and PreISelIntrinsicLowering to take advantage of this. The verifier will complain if an unsized type is used. I've additionally taken the opportunity to remove a comment from the LangRef about some bit widths potentially not being supported by the target. I don't think this is any more true than it is for arbitrary width loads/stores which don't carry a similar warning that I can see. A verifier check ensures that only sized types are used for the pattern.
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.
