Chris Lattner	a1f25b0020	Teach SD some vector identities, allowing us to compile vec_set-9 into: _test3: movd %rdi, %xmm1 #IMPLICIT_DEF %xmm0 punpcklqdq %xmm1, %xmm0 ret instead of: _test3: #IMPLICIT_DEF %rax movd %rax, %xmm0 movd %rdi, %xmm1 punpcklqdq %xmm1, %xmm0 ret This is still not ideal. There is no reason to two xmm regs. llvm-svn: 48058	2008-03-08 23:43:36 +00:00
