Hi,
Generic movhi genrates simple mov.
Actually the whole purpose of this intrinsic is to let complier know,
that this variable should pe placed on mask register and modified with
k<logic> instructions.
For example when compiling following with -O2 -mavx512f
bar (short x1,short y1,short z1, short f1)
{
short x,y,z,f;
x = _mm512_kmov(x1);
y = _mm512_kmov(11);
x ^= y;
a = _mm512_mask_add_ps (a,x,b,c);
}
Version with movhi produces xorl and no kmovw,
while version with unspec produces kxorw and kmovw.
