1. Always calculate when asked. This is the sort of optimization that just introduces bugs. Like one I hit when shuffling register indices around with the register access changes. 2. Ask before using in RA. 3. Account for precoloured blend inputs. Small shader-db hit, didn't investigate too much. total instructions in shared programs: 1518017 -> 1518168 (<.01%) instructions in affected programs: 2895 -> 3046 (5.22%) helped: 0 HURT: 24 Instructions are HURT. total bundles in shared programs: 646756 -> 646782 (<.01%) bundles in affected programs: 1119 -> 1145 (2.32%) helped: 1 HURT: 19 Bundles are HURT. total quadwords in shared programs: 1133694 -> 1133728 (<.01%) quadwords in affected programs: 1736 -> 1770 (1.96%) helped: 0 HURT: 20 Quadwords are HURT. total registers in shared programs: 90596 -> 90612 (0.02%) registers in affected programs: 108 -> 124 (14.81%) helped: 0 HURT: 16 Registers are HURT.
