This also fixes test failures in the clang-cl build configs that started a couple days ago. It seems like the failures were triggered by an update to the base image on the Github provided runners. There were failures in test/libcxx/system_reserved_names.gen.py, due to an issue in an Clang intrinsics header (avx512fp16intrin.h); this issue was observed and fixed for Clang 19 in 6f04f46927c. The test does #define A SYSTEM_RESERVED_NAME which clashes with a parameter with the name `A` in that header. By upgrading the toolchain to Clang 19, we get fixed version of this intrinsics header. Also update the llvm-mingw toolchains to a version with Clang 19.1.7.
The LLVM Compiler Infrastructure
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.
