The "gcc.dg/compat/vector-1 -m32" test was broken after the MMX rewrite. The
...
function parameters weren't converted to use the correct type (x86_mmx). Add a
check, similar to the one in llvm-gcc, to see if we need the x86_mmx type for
that function parameter. If so, it coerces the type to be that.

- Therefore, we can lower out the NEON wrapper structs and pass the vectors

IRgen/ABI/x86_32/Darwin: On Darwin, only structures with SSE vector types get passed

caused by my ABI work. Passing:
struct outer {

struct epsilon_matcher {} e;

as {i32,i32} isn't safe, because the offset of the second element
needs to be at 8 when it is interpreted as a memory value.

Finally pass "two floats in a 64-bit unit" as a <2 x float> instead of
...
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
