The SIMD (ie no conditional brances, as the "threads" are running
hardsynced, in parallel) way of doing it:
_output1 = some_opcode (arg1, arg2, arg3);
_output2 = some_other_opcode (arg3);
output = _output1 * variable + _output1 * (1 - variable);
Obviously, this means that both opcodes are evaluated all the time...
