<pre>I'm trying the inline assembler in clang, and find clang translates "mov
%%xmm0, (%%rdi)" into an movq. While it is not technically a bug, it is really
confusing, because I'm thinking something like movups.
I tried gcc, and gcc gives me an error, I need explicitly write movq to make
gcc emit a movq.
I think clang can emit a warning about the ambiguity.</pre>
