[clang][include cleaner] Fix MainHeader insertion issue (#212852) When doing multiple header insertions (like from include cleaner) there was an issue with MainHeaders inserted in the wrong location. HeaderIncludes now supports a bulk insertion where it sorts the insertions appropriately before inserting them to make sure that the MainHeader ends up in the correct location. Format.cpp has been updated to use the bulk insertion method correctly. Tests added to verify. GitOrigin-RevId: fc1ab1f288992fd22b4f562557ea38b0cc8f9aaf
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:
