[StrTable] Switch diag group names to `llvm::StringTable` (#123302) Previously, they used a hand-rolled Pascal-string encoding different from all the other string tables produced from TableGen. This moves them to use the newly introduced runtime abstraction, and enhances that abstraction to support iterating over the string table as used in this case. From what I can tell the Pascal-string encoding isn't critical here to avoid expensive `strlen` calls, so I think this is a simpler and more consistent model. But if folks would prefer a Pascal-string style encoding, I can instead work to switch the `StringTable` abstraction towards that. It would require some tricky tradeoffs though to make it reasonably general: either using 4 bytes instead of 1 byte to encode the size, or having a fallback to `strlen` for long strings.
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.
