+; We actually need to use -filetype=obj in this test because if we output
+; assembly, the current code path will bypass the parser and just write the
+; raw text out to the Streamer. We need to actually parse the inlineasm to
+; demonstrate the bug. Going the asm->obj route does not show the issue.
