--- Comment #3 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Perhaps something to report to llvm that they accept invalid, that is a bug.
Also, why do you use Intel syntax when you don't know how should it be used?
In AT&T syntax you wouldn't need to specify this extra stuff, just vpgatherdd
%xmm4, (%r13 + %xmm3), %xmm4. Also note that for inline asm you don't specify
clobbers etc. (but that might be just from simplification of the testcase).
