[gn build] Use shutil.which to find git in write_vcsrevision.py (#142570) Relates to https://github.com/llvm/llvm-project/issues/54337 This is just a comment referencing distutils but even so, we can ditch the custom which and use the one Python 3.3 added. Which has the .bat bug fixed: https://docs.python.org/3.3/library/shutil.html#shutil.which I tested this on Windows: ``` C:\Users\tcwg>touch foo.bat C:\Users\tcwg>python Python 3.11.9 (tags/v3.11.9:de54cf5, Apr 2 2024, 12:24:25) [MSC v.1938 64 bit (ARM64)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> import shutil >>> shutil.which("foo") '.\\foo.BAT' ``` I just ran the script manually and got reasonable results, I haven't done a GN build.
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.
Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.
The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
