Instead of last TMU write. According to the documentation, the entries in the output FIFO are pushed with the *final* input write for the lookup, which is the one terminating the sequence. We flag these with last_tmu_config. This will allow us to move all TMU register writes for a lookup except the last one ahead of the LDTMUs for the previous lookup, possibly allowing us to pair up these writes the wrtmuc instructions for the same lookup, turning code like this: nop ; nop ; wrtmuc (tex[0].p0 | 0x3) nop ; nop ; wrtmuc (tex[2].p1 | 0x1) nop ; nop ; ldunif (ubo[2]+0xe0) fadd r4, rf33, rf51 ; mov unifa, r5 ; ldunif (ubo[2]+0x110) fmax rf34, 0, r4 ; nop nop ; mov tmut, rf11 nop ; mov tmus, rf0 into: nop ; mov tmut, rf11 ; wrtmuc (tex[0].p0 | 0x3) nop ; nop ; wrtmuc (tex[2].p1 | 0x1) nop ; nop ; ldunif (ubo[2]+0xe0) fadd r4, rf33, rf51 ; mov unifa, r5 ; ldunif (ubo[2]+0x110) fmax rf34, 0, r4 ; nop nop ; mov tmus, rf0 total instructions in shared programs: 13648140 -> 13602500 (-0.33%) instructions in affected programs: 3497402 -> 3451762 (-1.30%) helped: 12044 HURT: 3484 Instructions are helped. total max-temps in shared programs: 2318687 -> 2317927 (-0.03%) max-temps in affected programs: 17234 -> 16474 (-4.41%) helped: 615 HURT: 198 Max-temps are helped. total sfu-stalls in shared programs: 32354 -> 32074 (-0.87%) sfu-stalls in affected programs: 1462 -> 1182 (-19.15%) helped: 461 HURT: 188 Sfu-stalls are helped. total inst-and-stalls in shared programs: 13680494 -> 13634574 (-0.34%) inst-and-stalls in affected programs: 3514405 -> 3468485 (-1.31%) helped: 12062 HURT: 3486 Inst-and-stalls are helped.
