Argh, Evolution dropped my indentation tabs. Let me try once more:
for (each VSrc operand) {
if (can be encoded as inline constant)
use inline constant;
if (is immediate &&
(no literal or SGPR yet || value matches literal))
use literal;
if (is VGPR || (is SGPR && no SGPR or literal yet))
use operand directly;
copy immediate/SGPR to VGPR and use the latter;
}
