Implement options in clang to enable recording the driver command-line in an ELF section. Implement a new special named metadata, llvm.commandline, to support frontends embedding their command-line options in IR/ASM/ELF. This differs from the GCC implementation in some key ways: * In GCC there is only one command-line possible per compilation-unit, in LLVM it mirrors llvm.ident and multiple are allowed. * In GCC individual options are separated by NULL bytes, in LLVM entire command-lines are separated by NULL bytes. The advantage of the GCC approach is to clearly delineate options in the face of embedded spaces. The advantage of the LLVM approach is to support merging multiple command-lines unambiguously, while handling embedded spaces with escaping.

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-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 web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
