Move Mask Operator

int i = move_mask(F64vec2 A)

Creates a 2-bit mask from the most significant bits of the two double precision floating-point values of A, as follows:

i := sign(a1)<<1 | sign(a0)<<0

Corresponding intrinsic: _mm_movemask_pd

int i = move_mask(F32vec4 A)

Creates a 4-bit mask from the most significant bits of the four single precision floating-point values of A, as follows:

i := sign(a3)<<3 | sign(a2)<<2 | sign(a1)<<1 | sign(a0)<<0

Corresponding intrinsic: _mm_movemask_ps
