| | | | | | | | | llc using the host cpu features and *waning* on unknown features is probably not a good thing :-( git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189144 91177308-0d34-0410-b5e6-96231b3b80d8 | ||
| * | fix the buildvector->insertp[sd] logic to not always create a redundant | Chris Lattner | 2010-08-28 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112379 91177308-0d34-0410-b5e6-96231b3b80d8 | ||
