            Bug ID: 39010
           Summary: Assembler directives cannot be separated by a
                    semicolon if aarch64 or arm64 is specified via -arch
                    instead of -triple
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: MC
          Assignee: unassignedbugs at nondot.org

$ echo '.if 0;.endif' | /usr/local/opt/llvm/bin/llvm-mc -triple arm64
        .text
$ echo '.if 0;.endif' | /usr/local/opt/llvm/bin/llvm-mc -arch arm64
        .text
<stdin>:2:1: error: unmatched .ifs or .elses

^

In this example, the first command succeeds, as it should. The second command
should be exactly equivalent, but it isn't; it doesn't allow directives to be
separated by semicolons and requires newlines instead.
