This patch is the fourth step to extend the current multilib system to support the selection of library variants which do not correspond to existing command-line options. Proposal can be found in https://discourse.llvm.org/t/rfc-multilib-custom-flags/81058 The multilib mechanism supports libraries that target code generation or language options such as --target, -mcpu, -mfpu, -mbranch-protection. However, some library variants are particular to features that do not correspond to any command-line options. Examples include variants for multithreading and semihosting. This work introduces a way to instruct the multilib system to consider these features in library selection. This particular patch updates the documentation.
C language Family Front-end
Welcome to Clang.
This is a compiler front-end for the C family of languages (C, C++ and Objective-C) which is built as part of the LLVM compiler infrastructure project.
Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer.
If you're interested in more (including how to build Clang) it is best to read the relevant websites. Here are some pointers:
