Revert "Reapply "[Clang][CMake] Use IRPGO instead of FE PGO for Cmake Caches … (#160133)" This reverts commit 6f64b01810a2e46c1b05b20589272532ba633e56. This breaks two BOLT buildbots using this cache: 1. https://lab.llvm.org/staging/#/builders/126/builds/2760 2. https://lab.llvm.org/buildbot/#/builders/113/builds/8571 More investigation needed, so reverting for now.
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.
For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.
