15 # ====================================================================
21 # Code uses 1K[+256B] S-box and on single-issue core [such as R5000]
22 # spends ~68 cycles per byte processed with 128-bit key. This is ~16%
23 # faster than gcc-generated code, which is not very impressive. But
24 # recall that compressed S-box requires extra processing, namely
25 # additional rotations. Rotations are implemented with lwl/lwr pairs,
26 # which is normally used for loading unaligned data. Another cool
27 # thing about this module is its endian neutrality, which means that
28 # it processes data without ever changing byte order...
32 # Add MIPS32R2 (~10% less instructions) and SmartMIPS ASE (further
33 # ~25% less instructions) code. Note that there is no run-time switch,
34 # instead, code path is chosen upon pre-process time, pass -mips32r2

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