In llvm the only semantic difference between internal and private is that llvm tries to hide private globals my mangling them with a private prefix. Since the globals changed by this patch already had the magic don't mangle marker, there should be no change in the generated assembly. A followup patch should then be able to drop the \01L and \01l prefixes and let llvm mangle as appropriate. llvm-svn: 202419
