Bill Wendling 2a03f15116 If the global variable is removed by the linker, then don't constant merge it ... with other symbols. An object in the __cfstring section is suppoed to be filled with CFString objects, which have a pointer to ___CFConstantStringClassReference followed by a pointer to a __cstring. If we allow the object in the __cstring section to be merged with another global, then it could end up in any section. Because the linker is going to remove these symbols in the final executable, we shouldn't bother to merge them. <rdar://problem/10564621> llvm-svn: 147899		2012-01-11 00:13:08 +00:00
