In assembly the expression a=b is parsed as an assignment, so it should be printed as one. This remove a truly horrible hack for producing a label with "a=.". It would be used by codegen but would never be reached by the asm parser. Sorry I missed this when it was first committed. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@211639 91177308-0d34-0410-b5e6-96231b3b80d8
