X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=d346736dfe5ef584a2d0c9d27d217408ee394b9b;p=clang

Made ObjC method name mangling match GCC (which does it in a stupid and broken way that can give conflicts on method names containing underscores, but is needed for gdb to work because gdb does not know how to read ObjC class tables and relies on the mangling).
