Chris Lattner 7900779543 handle the constant case of vector insertion. For something ... like this: struct S { float A, B, C, D; }; struct S g; struct S bar() { struct S A = g; ++A.B; A.A = 42; return A; } we now generate: _bar: ## @bar ## BB#0: ## %entry movq _g@GOTPCREL(%rip), %rax movss 12(%rax), %xmm0 pshufd $16, %xmm0, %xmm0 movss 4(%rax), %xmm2 movss 8(%rax), %xmm1 pshufd $16, %xmm1, %xmm1 unpcklps %xmm0, %xmm1 addss LCPI1_0(%rip), %xmm2 pshufd $16, %xmm2, %xmm2 movss LCPI1_1(%rip), %xmm0 pshufd $16, %xmm0, %xmm0 unpcklps %xmm2, %xmm0 ret instead of: _bar: ## @bar ## BB#0: ## %entry movq _g@GOTPCREL(%rip), %rax movss 12(%rax), %xmm0 pshufd $16, %xmm0, %xmm0 movss 4(%rax), %xmm2 movss 8(%rax), %xmm1 pshufd $16, %xmm1, %xmm1 unpcklps %xmm0, %xmm1 addss LCPI1_0(%rip), %xmm2 movd %xmm2, %eax shlq $32, %rax addq $1109917696, %rax ## imm = 0x42280000 movd %rax, %xmm0 ret git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@112345 91177308-0d34-0410-b5e6-96231b3b80d8		2010-08-28 01:50:57 +00:00
