[AMDGPU] Select VMEM prefetch for llvm.prefetch on gfx1250 (#150493) We have a choice to use a scalar or vector prefetch for an uniform pointer. Since we do not have scalar stores our scalar cache is practically readonly. The rw argument of the prefetch intrinsic is used to force vector operation even for an uniform case. On GFX12 scalar prefetch will be used anyway, it is still useful but it will only bring data to L2.
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.
