Note, the total - # use of U0, and the total use of L0 (after attending to the stores). - # which is part of the reason why.... - # - # This is a great schedule for the d_cache, a poor schedule for the - # b_cache. The lockup on U0 means that any stall can't be recovered - # from. Consider a ldq in L1. say that load gets stalled because it - # collides with a fill from the b_Cache. On the next cycle, this load - # gets priority. If first looks at L0, and goes there. The instruction - # we intended for L0 gets to look at L1, which is NOT where we want - # it. It either stalls 1, because it can't go in L0, or goes there, and - # causes a further instruction to stall. - # - # So for b_cache, we're likely going to want to put one or more cycles - # back into the code! And, of course, put in prefetches. For the - # accumulator, lds, intent to modify. For the multiplier, you might - # want ldq, evict next, if you're not wanting to use it again soon. Use - # 256 ahead of present pointer value. At a place where we have an mt - # followed by a bookkeeping, put the bookkeeping in upper, and the - # prefetch into lower. - # - # Note, the usage of physical registers per cycle is smoothed off, as - # much as possible. - # - # Note, the ldq's and stq's are at the end of the quadpacks. note, we'd - # like not to have a ldq or stq to preceded a conditional branch in a - # quadpack. The conditional branch moves the retire pointer one cycle - # later. - # - # Optimization notes: - # Callee-saves regs: $9 $10 $11 $12 $13 $14 $15 $26 ?$27? - # Reserved regs: $29 $30 $31 - # Free caller-saves regs in unrolled code: $24 $25 $28 - # We should swap some of the callee-saves regs for some of the free - # caller-saves regs, saving some overhead cycles. - # Most importantly, we should write fast code for the 0-7 case. - # The code we use there are for the 21164, and runs at 7 cycles/limb - # on the 21264. Should not be hard, if we write specialized code for - # 1-7 limbs (the one for 0 limbs should be straightforward). We then just - # need a jump table indexed by the low 3 bits of the count argument. - - .set noreorder - .set noat - .text - - .globl __mpn_addmul_1 - .ent __mpn_addmul_1 -__mpn_addmul_1: - .frame $30,0,$26,0 -
