[TableGen] Use bitwise operations to access HwMode ID.  (#88377)

1. Bitwise operations are used to access HwMode, allowing for the
coexistence of HwMode IDs for different features (such as RegInfo and
EncodingInfo). This will provide better scalability for HwMode.
Currently, most users utilize HwMode primarily for configuring
Register-related information, and few use it for configuring Encoding.
The limited scalability of HwMode has been a significant factor in this
usage pattern.
2. Sink the HwMode Encodings selection logic down to per instruction
level, this makes the logic for choosing encodings clearer and provides
better error messages.
3. Add some HwMode ID conflict detection to the getHwMode() interface.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

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.

Getting the Source Code and Building LLVM

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.

Getting in touch
