Clang currently picks the second tentative definition when VarDecl::getActingDefinition is called. This can lead to attributes being dropped if they are attached to tentative definitions that appear after the second one. This is because VarDecl::getActingDefinition loops through VarDecl::redecls assuming that the last tentative definition is the last element in the iterator. However, it is the second element that would be the last tentative definition. This changeset modifies getActingDefinition to iterate through the declaration chain in reverse, so that it can immediately return when it encounters a tentative definition. Originally the unit test for this changeset did not have a -triple flag for the clang invocation, leading to this test being broken on MacOS, since Mach-O does not support the section attribute.

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