Subject: When an inline-asm diagnostic is reported by the backend, report it with the
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=9266985b619ddd85632a0616af41f0e917646c24;p=clang

When an inline-asm diagnostic is reported by the backend, report it with the
correct severity.

Previously all inline-asm diagnostics were reported as errors.
