UNPCK

Format: UNPCK.format dest, source.

Phase0: UNPCK.format{.SCALE}{.ROUNDZERO} FT0, S0{.E0|.E1|.E2|.E3}

Phase1: -

Phase2: -

Description: Unpack by data format.

Similarly UPCK with a REPEAT of n produce results in n sequential register locations.

FT0 = unpack(S0)

Data formats supported: U8888, S8888, S8888OGL, O8888, U1616, S1616, S1616OGL, O1616, F16F16, U32, S32, F32, F32MASK, U1010102, S1010102, 2F102F10F10, U111110, S111110, F111110, SE9995, U565U565, S8D24, D24S8

Example:

void main()
{
    fragColor = vec4(float(i));
}

0    : unpck.s1616 ft0, sh0.e0
       mov r0.e0.e1.e2.e3, ft0
       mov r1, ft0;
