We currently force symbols to be globals in .thumb_set. The intent seems to be that given .thumb_set foo, bar we emit an undefined symbol to bar if it is never defined. The side effect is that we mark bar as global, even if it is defined, which gas does not. Producing an undefined reference to bar is a general difference from MC and gas. For example, given a = b gas will produce an undefined reference to b, MC will not. I would be surprised if any code depends on this, but it it does, we should fix the general difference, not special case .thumb_set. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@207757 91177308-0d34-0410-b5e6-96231b3b80d8
