  13 #
  14 # SHA256 performance improvement on MIPS R5000 CPU is ~27% over gcc-
  15 # generated code in o32 build and ~55% in n32/64 build. SHA512 [which
  16 # for now can only be compiled for MIPS64 ISA] improvement is modest
  17 # ~17%, but it comes for free, because it's same instruction sequence.
  18 # Improvement coefficients are for aligned input.

  22 # Add MIPS[32|64]R2 code (>25% less instructions).

  25 # There is a number of MIPS ABI in use, O32 and N32/64 are most
  26 # widely used. Then there is a new contender: NUBI. It appears that if
  27 # one picks the latter, it's possible to arrange code in ABI neutral
  28 # manner. Therefore let's stick to NUBI register layout:
  29 #
  30 ($zero,$at,$t0,$t1,$t2)=map("\$$_",(0..2,24,25));
  31 ($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
  32 ($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7,$s8,$s9,$s10,$s11)=map("\$$_",(12..23));
  33 ($gp,$tp,$sp,$fp,$ra)=map("\$$_",(3,28..31));
  34 #
  35 # The return value is placed in $a0. Following coding rules facilitate
  36 # interoperability:
  37 #
  38 # - never ever touch $tp, "thread pointer", former $gp [o32 can be
  39 #   excluded from the rule, because it's specified volatile];
  40 # - copy return value to $t0, former $v0 [or to $a0 if you're adapting
  41 #   old code];
  42 # - on O32 populate $a4-$a7 with 'lw $aN,4*N($sp)' if necessary;
  43 #
  44 # For reference here is register layout for N32/64 MIPS ABIs:
  45 #
  46 # ($zero,$at,$v0,$v1)=map("\$$_",(0..3));
  47 # ($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
  48 # ($t0,$t1,$t2,$t3,$t8,$t9)=map("\$$_",(12..15,24,25));
