Currently we have code with target hooks in CodeGenModule shared between X86 and AArch64 for sorting MultiVersionResolverOptions. Those are used when generating IFunc resolvers for FMV. The RISCV target has different criteria for sorting, therefore it repeats sorting after calling CodeGenFunction::EmitMultiVersionResolver. I am moving the FMV priority logic in TargetInfo, so that it can be implemented by the TargetParser which then makes it possible to query it from llvm. Here is an example why this is handy: https://github.com/llvm/llvm-project/pull/87939
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:
