<pre>This is an old bug using an old toolchain that wasn't even upstream.
Furthermore, the problem is that I don't think that IR will never be reached
from normal inline asm. Both GCC and Clang bail out before generating empty
output register list (front-end syntax error).
Finally, the IR generates an UNREACHABLE, which is how we treat badly formed
input that can never be generated by users anyway. I don't see anything wrong
with that.
If someone cares enough and can reproduce this IR from C source with an recent
upstream toolchain, please re-open this bug.</pre>
