[Github] Fix LLVM Project Tests Workflow on Linux (#122221) This patch fixes the LLVM project tests workflow on Linux. Two changes were needed. Firstly, some commands need to be performed with sudo now that the container executes as a non-root user. Second, we needed to change from `ubuntu-latest` to `ubuntu-22.04` as `ubuntu-latest` not defaults to `ubuntu-24.04` which causes `setup-python` to install a python executable linked against a newer version of glibc that is not found on ubuntu 22.04, which causes failures when CMake cannot execute the python interpreter that it finds.
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.
