Problem with gnu conditional extension with missing

LHS and when conditional expression is an array. Since
it will be decayed, saved expression must be saved with
decayed expression. This is necessary to preserve semantics
of this extension (and prevent an IRGen crash which expects
an array to always be decayed). I am sure there will be other
cases in c++ (aggregate conditionals for example) when saving of the
expression must happen after some transformation on conditional
expression has happened.

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

Only run the jump-checker if there's a branch-protected scope *and* there's
...
a switch or goto somewhere in the function. Indirect gotos trigger the
jump-checker regardless, because the conditions there are slightly more
elaborate and it's too marginal a case to be worth optimizing.
Turns off the jump-checker in a lot of cases in C++. rdar://problem/7702918

fix rdar://8251384, another case where we could access beyond the
...
end of a struct. This improves the case when the struct being passed
contains 3 floats, either due to a struct or array of 3 things. Before
we'd generate this IR for the testcase:
define float @bar(double %X.coerce0, double %X.coerce1) nounwind {
entry:
%X = alloca %struct.foof, align 8 ; <%struct.foof*> [#uses=2]
%0 = bitcast %struct.foof* %X to %1* ; <%1*> [#uses=2]
%1 = getelementptr %1* %0, i32 0, i32 0 ; <double*> [#uses=1]
store double %X.coerce0, double* %1
%2 = getelementptr %1* %0, i32 0, i32 1 ; <double*> [#uses=1]
store double %X.coerce1, double* %2
%tmp = getelementptr inbounds %struct.foof* %X, i32 0, i32 2 ; <float*> [#uses=1]
%tmp1 = load float* %tmp ; <float> [#uses=1]
ret float %tmp1
}
which compiled (with optimization) to:
_bar: ## @bar
## BB#0: ## %entry
movd %xmm1, %rax
movd %eax, %xmm0
ret
Now we produce:
define float @bar(double %X.coerce0, float %X.coerce1) nounwind {
entry:
%X = alloca %struct.foof, align 8 ; <%struct.foof*> [#uses=2]
%0 = bitcast %struct.foof* %X to %0* ; <%0*> [#uses=2]
%1 = getelementptr %0* %0, i32 0, i32 0 ; <double*> [#uses=1]
store double %X.coerce0, double* %1
%2 = getelementptr %0* %0, i32 0, i32 1 ; <float*> [#uses=1]
store float %X.coerce1, float* %2
%tmp = getelementptr inbounds %struct.foof* %X, i32 0, i32 2 ; <float*> [#uses=1]
%tmp1 = load float* %tmp ; <float> [#uses=1]
ret float %tmp1
}
and:
_bar: ## @bar
## BB#0: ## %entry
movaps %xmm1, %xmm0
ret

This is a little bit far, but optimize cases like:
...
struct a {
struct c {
double x;
int y;
} x[1];
};
void foo(struct a A) {
}
into:
define void @foo(double %A.coerce0, i32 %A.coerce1) nounwind {
entry:
%A = alloca %struct.a, align 8 ; <%struct.a*> [#uses=1]
%0 = bitcast %struct.a* %A to %struct.c* ; <%struct.c*> [#uses=2]
%1 = getelementptr %struct.c* %0, i32 0, i32 0 ; <double*> [#uses=1]
store double %A.coerce0, double* %1
%2 = getelementptr %struct.c* %0, i32 0, i32 1 ; <i32*> [#uses=1]
store i32 %A.coerce1, i32* %2
instead of:
define void @foo(double %A.coerce0, i64 %A.coerce1) nounwind {
entry:
%A = alloca %struct.a, align 8 ; <%struct.a*> [#uses=1]
%0 = bitcast %struct.a* %A to %0* ; <%0*> [#uses=2]
%1 = getelementptr %0* %0, i32 0, i32 0 ; <double*> [#uses=1]
store double %A.coerce0, double* %1
%2 = getelementptr %0* %0, i32 0, i32 1 ; <i64*> [#uses=1]
store i64 %A.coerce1, i64* %2
I only do this now because I never want to look at this code again :)

implement a todo: pass a eight-byte that consists of a
...
small integer + padding as that small integer. On code
like:
struct c { double x; int y; };
void bar(struct c C) { }
This means that we compile to:
define void @bar(double %C.coerce0, i32 %C.coerce1) nounwind {
entry:
%C = alloca %struct.c, align 8 ; <%struct.c*> [#uses=2]
%0 = getelementptr %struct.c* %C, i32 0, i32 0 ; <double*> [#uses=1]
store double %C.coerce0, double* %0
%1 = getelementptr %struct.c* %C, i32 0, i32 1 ; <i32*> [#uses=1]
store i32 %C.coerce1, i32* %1
instead of:
define void @bar(double %C.coerce0, i64 %C.coerce1) nounwind {
entry:
%C = alloca %struct.c, align 8 ; <%struct.c*> [#uses=3]
%0 = bitcast %struct.c* %C to %0* ; <%0*> [#uses=2]
%1 = getelementptr %0* %0, i32 0, i32 0 ; <double*> [#uses=1]
store double %C.coerce0, double* %1
%2 = getelementptr %0* %0, i32 0, i32 1 ; <i64*> [#uses=1]
store i64 %C.coerce1, i64* %2
which gives SRoA heartburn.
This implements rdar://5711709, a nice low number :)

Kill off the 'coerce' ABI passing form. Now 'direct' and 'extend' always
...
have a "coerce to" type which often matches the default lowering of Clang
type to LLVM IR type, but the coerce case can be handled by making them
not be the same.
This simplifies things and fixes issues where X86-64 abi lowering would
return coerce after making preferred types exactly match up. This caused
us to compile:
typedef float v4f32 __attribute__((__vector_size__(16)));
v4f32 foo(v4f32 X) {
return X+X;
}
into this code at -O0:
define <4 x float> @foo(<4 x float> %X.coerce) nounwind {
entry:
%retval = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=2]
%coerce = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=2]
%X.addr = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=3]
store <4 x float> %X.coerce, <4 x float>* %coerce
%X = load <4 x float>* %coerce ; <<4 x float>> [#uses=1]
store <4 x float> %X, <4 x float>* %X.addr
%tmp = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1]
%tmp1 = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1]
%add = fadd <4 x float> %tmp, %tmp1 ; <<4 x float>> [#uses=1]
store <4 x float> %add, <4 x float>* %retval
%0 = load <4 x float>* %retval ; <<4 x float>> [#uses=1]
ret <4 x float> %0
}
Now we get:
define <4 x float> @foo(<4 x float> %X) nounwind {
entry:
%X.addr = alloca <4 x float>, align 16 ; <<4 x float>*> [#uses=3]
store <4 x float> %X, <4 x float>* %X.addr
%tmp = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1]
%tmp1 = load <4 x float>* %X.addr ; <<4 x float>> [#uses=1]
%add = fadd <4 x float> %tmp, %tmp1 ; <<4 x float>> [#uses=1]
ret <4 x float> %add
}
This implements rdar://8248065

ignore structs that wrap vectors in IR, the abstraction shouldn't add penalty.
...
Before we'd compile the example into something like:
%coerce.dive2 = getelementptr %struct.v4f32wrapper* %retval, i32 0, i32 0 ; <<4 x float>*> [#uses=1]
%1 = bitcast <4 x float>* %coerce.dive2 to <2 x double>* ; <<2 x double>*> [#uses=1]
%2 = load <2 x double>* %1, align 1 ; <<2 x double>> [#uses=1]
ret <2 x double> %2
Now we produce:
%coerce.dive2 = getelementptr %struct.v4f32wrapper* %retval, i32 0, i32 0 ; <<4 x float>*> [#uses=1]
%0 = load <4 x float>* %coerce.dive2, align 1 ; <<4 x float>> [#uses=1]
ret <4 x float> %0
