Agreed. This was a low hanging fruit for me as the "work around" for std::basic_string was already in place. I only made the matching prefix complete. Even things like invocation of std::map<std::string, int>::size are still broken as clang tries to demangle std::map<std::basic_string<...>, int, ...>::size and since the debug info for some of the template params is missing, it ends up with the uncompressed mangling. A point to note here is that GCC emits the compressed mangled name in the DWARF, but that is not read at all by LLDB. May be we can make clang use that name instead of generating a mangled name itself. Just a may be; I will look into fixing this thoroughly next. http://reviews.llvm.org/D8846 EMAIL PREFERENCES http://reviews.llvm.org/settings/panel/emailpreferences/ _______________________________________________ lldb-commits mailing list [email protected] http://lists.cs.uiuc.edu/mailman/listinfo/lldb-commits
