[AMDGPU] Pack instruction format and modifier TSFlags bits into enums, NFC. The instruction-format bits in TSFlags are mutually exclusive, so collapse them into a single 5-bit Format enum and likewise FormatModifier enum for DPP/SDWA. This frees 18 TSFlags bits. For now Format is derived from individual TableGen bitfields to minimize the patch, but next commit will remove those. All raw format-bit tests already go through the SIInstrFlags predicates, so no call sites change. Co-Authored-By: Claude <noreply@anthropic.com>
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.
