17 # SHA2 block procedures for MIPS.
21 # SHA256 performance improvement on MIPS R5000 CPU is ~27% over gcc-
22 # generated code in o32 build and ~55% in n32/64 build. SHA512 [which
23 # for now can only be compiled for MIPS64 ISA] improvement is modest
24 # ~17%, but it comes for free, because it's same instruction sequence.
25 # Improvement coefficients are for aligned input.
29 # Add MIPS[32|64]R2 code (>25% less instructions).
31 ######################################################################
32 # There is a number of MIPS ABI in use, O32 and N32/64 are most
33 # widely used. Then there is a new contender: NUBI. It appears that if
34 # one picks the latter, it's possible to arrange code in ABI neutral
35 # manner. Therefore let's stick to NUBI register layout:
37 ($zero,$at,$t0,$t1,$t2)=map("\$$_",(0..2,24,25));
38 ($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
39 ($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7,$s8,$s9,$s10,$s11)=map("\$$_",(12..23));
40 ($gp,$tp,$sp,$fp,$ra)=map("\$$_",(3,28..31));
42 # The return value is placed in $a0. Following coding rules facilitate
45 # - never ever touch $tp, "thread pointer", former $gp [o32 can be
46 # excluded from the rule, because it's specified volatile];
47 # - copy return value to $t0, former $v0 [or to $a0 if you're adapting
49 # - on O32 populate $a4-$a7 with 'lw $aN,4*N($sp)' if necessary;
51 # For reference here is register layout for N32/64 MIPS ABIs:
53 # ($zero,$at,$v0,$v1)=map("\$$_",(0..3));
54 # ($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
55 # ($t0,$t1,$t2,$t3,$t8,$t9)=map("\$$_",(12..15,24,25));
56 # ($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7)=map("\$$_",(16..23));
57 # ($gp,$sp,$fp,$ra)=map("\$$_",(28..31));
59 # if $output doesn't have an extension, it's not an output file
