10# SHA2 block procedures for MIPS.
11
12# October 2010.
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.
19
20# September 2012.
21#
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));
49# ($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7)=map("\$$_",(16..23));
50# ($gp,$sp,$fp,$ra)=map("\$$_",(28..31));
