2010-08-26fix 2xi16 to pass as i32 instead of <2 x i16>. The former passes inChris Lattner
memory (as required) the later now passes in an xmm register. This fixes gcc.dg/compat/vector_1 on x86-32. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112211 91177308-0d34-0410-b5e6-96231b3b80d8

2010-08-25Finally pass "two floats in a 64-bit unit" as a <2 x float> instead ofChris Lattner
as a double in the x86-64 ABI. This allows us to generate much better code for certain things, e.g.: _Complex float f32(_Complex float A, _Complex float B) { return A+B; } Used to compile into (look at the integer silliness!): _f32: ## @f32 ## BB#0: ## %entry movd %xmm1, %rax movd %eax, %xmm1 movd %xmm0, %rcx movd %ecx, %xmm0 addss %xmm1, %xmm0 movd %xmm0, %edx shrq $32, %rax movd %eax, %xmm0 shrq $32, %rcx movd %ecx, %xmm1 addss %xmm0, %xmm1 movd %xmm1, %eax shlq $32, %rax addq %rdx, %rax movd %rax, %xmm0 ret Now we get: _f32: ## @f32 movdqa %xmm0, %xmm2 addss %xmm1, %xmm2 pshufd $16, %xmm2, %xmm2 pshufd $1, %xmm1, %xmm1 pshufd $1, %xmm0, %xmm0 addss %xmm1, %xmm0 pshufd $16, %xmm0, %xmm1 movdqa %xmm2, %xmm0 unpcklps %xmm1, %xmm0 ret and compile stuff like: extern float _Complex ccoshf( float _Complex ) ; float _Complex ccosf ( float _Complex z ) { float _Complex iz; (__real__ iz) = -(__imag__ z); (__imag__ iz) = (__real__ z); return ccoshf(iz); } into: _ccosf: ## @ccosf ## BB#0: ## %entry pshufd $1, %xmm0, %xmm1 xorps LCPI4_0(%rip), %xmm1 unpcklps %xmm0, %xmm1 movaps %xmm1, %xmm0 jmp _ccoshf ## TAILCALL instead of: _ccosf: ## @ccosf ## BB#0: ## %entry movd %xmm0, %rax movq %rax, %rcx shlq $32, %rcx shrq $32, %rax xorl $-2147483648, %eax ## imm = 0xFFFFFFFF80000000 addq %rcx, %rax movd %rax, %xmm0 jmp _ccoshf ## TAILCALL There is still "stuff to be done" here for the struct case, but this resolves rdar://6379669 - [x86-64 ABI] Pass and return _Complex float / double efficiently git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@112111 91177308-0d34-0410-b5e6-96231b3b80d8
