The new behavior matches GNU objdump. A pair of angle brackets makes tests slightly easier. `.foo:` is not unique and thus cannot be used in a `CHECK-LABEL:` directive. Without `-LABEL`, the CHECK line can match the `Disassembly of section` line and causes the next `CHECK-NEXT:` to fail. ``` Disassembly of section .foo: 0000000000001634 .foo: ``` Bdragon: <> has metalinguistic connotation. it just "feels right" Reviewed By: rupprecht Differential Revision: https://reviews.llvm.org/D75713
