Pack Operators

Pack the eight 32-bit values found in
A
and
B
into eight 16-bit values with signed saturation.
Is16vec8 pack_sat(Is32vec2 A,Is32vec2 B);
Corresponding intrinsic:
_mm_packs_epi32
Pack the four 32-bit values found in
A
and
B
into eight 16-bit values with signed saturation.
Is16vec4 pack_sat(Is32vec2 A,Is32vec2 B);
Corresponding intrinsic:
_mm_packs_pi32
Pack the sixteen 16-bit values found in
A
and
B
into sixteen 8-bit values with signed saturation.
