Subject: When creating a dwarf record type for an objc interface, make sure to propagate
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=ac7c814d817bbfafd924586b9025f2dffc655708;p=clang

When creating a dwarf record type for an objc interface, make sure to propagate
the runtime version number onto it, so that the debugger knows it's an objc
interface, not a C struct.  rdar://6848435
