Chris Lattner 19a5dc488b optimize bitcast(trunc(bitcast(x))) where the result is a float and 'x' ... is a vector to be a vector element extraction. This allows clang to compile: struct S { float A, B, C, D; }; float foo(struct S A) { return A.A + A.B+A.C+A.D; } into: _foo: ## @foo ## BB#0: ## %entry movd %xmm0, %rax shrq $32, %rax movd %eax, %xmm2 addss %xmm0, %xmm2 movapd %xmm1, %xmm3 addss %xmm2, %xmm3 movd %xmm1, %rax shrq $32, %rax movd %eax, %xmm0 addss %xmm3, %xmm0 ret instead of: _foo: ## @foo ## BB#0: ## %entry movd %xmm0, %rax movd %eax, %xmm0 shrq $32, %rax movd %eax, %xmm2 addss %xmm0, %xmm2 movd %xmm1, %rax movd %eax, %xmm1 addss %xmm2, %xmm1 shrq $32, %rax movd %eax, %xmm0 addss %xmm1, %xmm0 ret ... eliminating half of the horribleness. llvm-svn: 112227		2010-08-26 21:55:42 +00:00
