-# SHA2 block procedures for MIPS.
-
-# October 2010.
-#
-# SHA256 performance improvement on MIPS R5000 CPU is ~27% over gcc-
-# generated code in o32 build and ~55% in n32/64 build. SHA512 [which
-# for now can only be compiled for MIPS64 ISA] improvement is modest
-# ~17%, but it comes for free, because it's same instruction sequence.
-# Improvement coefficients are for aligned input.

-# There is a number of MIPS ABI in use, O32 and N32/64 are most
-# widely used. Then there is a new contender: NUBI. It appears that if
-# one picks the latter, it's possible to arrange code in ABI neutral
-# manner. Therefore let's stick to NUBI register layout:
-#
-($zero,$at,$t0,$t1,$t2)=map("\$$_",(0..2,24,25));
-($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
-($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7,$s8,$s9,$s10,$s11)=map("\$$_",(12..23));
-($gp,$tp,$sp,$fp,$ra)=map("\$$_",(3,28..31));
-#
-# The return value is placed in $a0. Following coding rules facilitate
-# interoperability:
-#
-# - never ever touch $tp, "thread pointer", former $gp [o32 can be
-#   excluded from the rule, because it's specified volatile];
-# - copy return value to $t0, former $v0 [or to $a0 if you're adapting
-#   old code];
-# - on O32 populate $a4-$a7 with 'lw $aN,4*N($sp)' if necessary;
-#
-# For reference here is register layout for N32/64 MIPS ABIs:
-#
-# ($zero,$at,$v0,$v1)=map("\$$_",(0..3));
-# ($a0,$a1,$a2,$a3,$a4,$a5,$a6,$a7)=map("\$$_",(4..11));
-# ($t0,$t1,$t2,$t3,$t8,$t9)=map("\$$_",(12..15,24,25));
-# ($s0,$s1,$s2,$s3,$s4,$s5,$s6,$s7)=map("\$$_",(16..23));
-# ($gp,$sp,$fp,$ra)=map("\$$_",(28..31));
