[MSan] Separated PPC32 va_arg helper from PPC64 (#131827) With more understanding of PowerPC32 ABI we've rewritten the `VarArgPowerPC32Helper`. New implementation fills shadow for both `reg_save_area` and `overflow_arg_area`. It does not copy shadow for floating-point arguments, as they are stored in a separate space. This implementation does not fully support passing arguments `byVal`. This will be fixed in future PRs. Tests were also updated via `llvm/utils/update_test_checks.py`.
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.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
