515 Pentium2+ optimisation notes:
516
517 - "uop" comment formating:
518 A/B means "A micro-ops in port 0, and B micro-ops in port 2". (port 1 is very rare for FPU)
519 A/B/C/D means "A micro-ops in port 0, B in port 2, C in port 3 and D in port 4".
520 The number in () is the delay (if any).
521 - the "compute lighting part" must done first, because of the "fistp f8" mem writes that must
522 be place far away from the "mov eax, f8" read in clamp lighting part
523 (else seems that it crashes all the //ism)
524 - No need to Interleave on Pentium2+. But prevents "write/read stall" by putting the write
525 far away from the next read. Else stall of 3 cycles + BIG BREAK OF //ism (I think).
526 This had save me 120 cycles / 240 !!!
527
528 BenchResults:
529 - The "transform vertex part" and "all next part" cost 42 cycles, but is somewhat optimal:
530 63 uop (=> min 21 cycles), but 36 uop in the P0 port (=> this is the bottleneck)
531 - The lighting part adds 1 cycle only ????? (44 cycles) But still relevant and optimal:
532 43 uop in port P0!!!!
533 - The UV part adds 4 cycles (47) (should not since 0 in Port P0), still acceptable.
534 - The clamp part adds 3 cycles (50), and add 11 cycles in "P0 or P1" (but heavy dependency)
535 If we assume all goes into P1, it should takes 0... still acceptable (optimal==43?)
536 - The alpha part adds 2 cycles (52, optimal=45). OK.
537 - The modulate part adds 15 cycles. OK
538
539 TOTAL: 67 cycles in theory (write in RAM, no cache miss problem)
540 BENCH: ASM version: 91 cycles (Write in AGP, some cache miss problems, still good against 67)
541 C version: 316 cycles.
