Well apparently stores w/ dmd's weird core.simd interface don't work, or
I can't figure out (from the non-existent documentation) how to use it.
---
import core.simd;
void test(float4* ptr, float4 val)
{
__simd_sto(XMM.STOUPS, *ptr, val);
__simd(XMM.STOUPS, *ptr, val);
auto val1 = __simd_sto(XMM.STOUPS, *ptr, val);
auto val2 = __simd(XMM.STOUPS, *ptr, val);
}

LDC at least has some intrinsics once you find ldc.gccbuiltins_x86, but
for some reason comes with it's own broken ldc.simd.loadUnaligned
instead of providing intrinsics.
---
import core.simd, ldc.simd;
float4 test(float* ptr)
{
return loadUnaligned!float4(ptr);
}

/home/dawg/dlang/ldc-0.17.1/bin/../import/ldc/simd.di(212): Error: can't
parse inline LLVM IR:
%r = load <4 x float>* %p, align 1
^
expected comma after load's type
So are 3 different untested and unused APIs really the current state of
SIMD?
