In post-commit feedback on D104830 Jessica Clarke pointed out that unconditionally adding __va_list to the std namespace caused namespace debug info to be emitted in C, which is not only inappropriate but turned out to confuse the dtrace tool. Therefore, move __va_list back to std only in C++ so that the correct debug info is generated. We also considered moving __va_list to the top level unconditionally but this would contradict the specification and be visible to AST matchers and such, so make it conditional on the language mode. To avoid breaking name mangling for __va_list, teach the Itanium name mangler to always mangle it as if it were in the std namespace when targeting ARM architectures. This logic is not needed for the Microsoft name mangler because Microsoft platforms define va_list as a typedef of char *. Depends on D116773 Differential Revision: https://reviews.llvm.org/D116774 |

//===----------------------------------------------------------------------===// // 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/
