[AMDGPU] Change SGPR layout to striped caller/callee saved (#127353) This PR updates the SGPR layout to a striped caller/callee-saved design, similar to the VGPR layout. To ensure that s30-s31 (return address), s32 (stack pointer), s33 (frame pointer), and s34 (base pointer) remain callee-saved, the striped layout starts from s40, with a stripe width of 8. The last stripe is 10 wide instead of 8 to avoid ending with a 2-wide stripe. Fixes #113782.
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.
