Subject: Add a missing pattern for movhps so that we get:
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=7cdba6d1f44ac3db194a68b318f175c1f5cf5016;p=oota-llvm.git

Add a missing pattern for movhps so that we get:

movq	(%ecx,%edx,2), %xmm2
movhps	(%ecx,%eax,2), %xmm2

rather than:

movq     (%eax, %edx, 2), %xmm2
movq     (%eax, %ebx, 2), %xmm3
movlhps  %xmm3, %xmm2

Testcase forthcoming.
