[SPIR-V] Stop using Register to represent target specific virtual registers. (#129362) These were using the virtual register encoding in Register which required including Register.h in MC layer code which is a layering violation. This also required converting Register with bit 31 set to MCRegister which should be an error. Register with bit 31 set should only be used for codegen virtual register. I'd like to add assertions to enforce this. Migrate to MCRegister and manually create an encoding with bit 31 set. WebAssembly also does this. We could consider adding interfaces to MCRegister for target specific virtual registers.
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.
