Chris Lattner	94656b1c8c	fix the buildvector->insertp[sd] logic to not always create a redundant ... insertp[sd] $0, which is a noop. Before: _f32: ## @f32 pshufd $1, %xmm1, %xmm2 pshufd $1, %xmm0, %xmm3 addss %xmm2, %xmm3 addss %xmm1, %xmm0 ## kill: XMM0<def> XMM0<kill> XMM0<def> insertps $0, %xmm0, %xmm0 insertps $16, %xmm3, %xmm0 ret after: _f32: ## @f32 movdqa %xmm0, %xmm2 addss %xmm1, %xmm2 pshufd $1, %xmm1, %xmm1 pshufd $1, %xmm0, %xmm3 addss %xmm1, %xmm3 movdqa %xmm2, %xmm0 insertps $16, %xmm3, %xmm0 ret The extra movs are due to a random (poor) scheduling decision. llvm-svn: 112379	2010-08-28 17:59:08 +00:00

Chris Lattner	b9cdd3153c	change a test to run in filecheck style. Rename it to be a general ... dumping ground of various SSE4.1 tests, since filecheck can reasonably handle them all in one file. Generalize it to check x86-64 stuff as well since it has a different ABI (a convenient way to test both the reg and mem forms of these instructions). llvm-svn: 76848	2009-07-23 04:33:02 +00:00
