[compiler-rt][cmake] Fix check_cxx_compiler_flag calls (#197529) check_cxx_compiler_flag, when passing multiple flags, we must separate them using a SEMICOLON-separated list. Not spaces. These checks succeed incorrectly sometimes because "-Werror -mcrc" has a different return value than "-Werror" "-mcrc" on some systems. This issue was verified with LLVM_ENABLE_PROJECTS=llvm;compiler-rt, and I'm uncertain whether it exists in runtime CMake builds. Nonetheless, it's still a bug. See: https://cmake.org/cmake/help/latest/module/CheckCXXCompilerFlag.html This issue was identified downstream in ChromiumOS. ChromiumOS Bug: https://issuetracker.google.com/507177988
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.
