[Docs] Some updates to the Clang user's manual (#151702) * Fills out the terminology section * Removes the basic usage section (we should bring it back someday though!) * Updates the list of supported language versions * Adds information about what versions of Clang are officially supported * Moves some extensions into the intentionally unsupported extensions section. There are likely far more updates that could be done, but this seemed worth posting just to get things moving.
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.
