TSTL

Format: TSTL dest, destPredWrite, sourceLHS, sourceRHS.

Phase0: -

Phase1: -

Phase2: TSTL{.type} FTT, (P0|_), IS1{.F16}{.E0|.E1|.E2|.E3}, IS2{.F16}{.E0|.E1|.E2|.E3}

Description: Test less than.

LHS < RHS

Example:

uniform highp int a;
uniform highp int b;

void main()
{
    highp int res;

    if( a < b )
    {
        res = a;
    }
    else
    {
        res = b;
    }

    fragColor = vec4(res);
}
