The module is, however, dual licensed under OpenSSL and +# CRYPTOGAMS licenses depending on where you obtain it. For further +# details see http://www.openssl.org/~appro/cryptogams/. +# ==================================================================== + +# December 2005 +# +# Pure SPARCv9/8+ and IALU-only bn_mul_mont implementation. The reasons +# for undertaken effort are multiple. First of all, UltraSPARC is not +# the whole SPARCv9 universe and other VIS-free implementations deserve +# optimized code as much. Secondly, newly introduced UltraSPARC T1, +# a.k.a. Niagara, has shared FPU and concurrent FPU-intensive pathes, +# such as sparcv9a-mont, will simply sink it. Yes, T1 is equipped with +# several integrated RSA/DSA accelerator circuits accessible through +# kernel driver [only(*)], but having decent user-land software +# implementation is important too. Finally, reasons like desire to +# experiment with dedicated squaring procedure. Yes, this module +# implements one, because it was easiest to draft it in SPARCv9 +# instructions... + +# (*) Engine accessing the driver in question is on my TODO list. +# For reference, acceleator is estimated to give 6 to 10 times +# improvement on single-threaded RSA sign. It should be noted +# that 6-10x improvement coefficient does not actually mean +# something extraordinary in terms of absolute [single-threaded] +# performance, as SPARCv9 instruction set is by all means least +# suitable for high performance crypto among other 64 bit +# platforms. 6-10x factor simply places T1 in same performance +# domain as say AMD64 and IA-64. Improvement of RSA verify don't +# appear impressive at all, but it's the sign operation which is +# far more critical/interesting. + +# You might notice that inner loops are modulo-scheduled:-) This has +# essentially negligible impact on UltraSPARC performance, it's +# Fujitsu SPARC64 V users who should notice and hopefully appreciate +# the advantage... Currently this module surpasses sparcv9a-mont.pl +# by ~20% on UltraSPARC-III and later cores, but recall that sparcv9a +# module still have hidden potential [see TODO list there], which is +# estimated to be larger than 20%... + +# int bn_mul_mont( +$rp="%i0"; # BN_ULONG *rp, +$ap="%i1"; # const BN_ULONG *ap, +$bp="%i2"; # const BN_ULONG *bp, +$np="%i3"; # const BN_ULONG *np, +$n0="%i4"; # const BN_ULONG *n0, +$num="%i5"; # int num); + +$bits=32; +for (@ARGV) { $bits=64 if (/\-m64/ || /\-xarch\=v9/); } +if ($bits==64) { $bias=2047; $frame=192; } +else { $bias=0; $frame=128; } + +$car0="%o0"; +$car1="%o1"; +$car2="%o2"; # 1 bit +$acc0="%o3"; +$acc1="%o4"; +$mask="%g1"; # 32 bits, what a waste... +$tmp0="%g4"; +$tmp1="%g5"; + +$i="%l0"; +$j="%l1"; +$mul0="%l2"; +$mul1="%l3"; +$tp="%l4"; +$apj="%l5"; +$npj="%l6"; +$tpj="%l7"; + +$fname="bn_mul_mont_int"; + +$code=<<___; +.section ".text",#alloc,#execinstr + +.global $fname +.align 32 +$fname: + cmp %o5,4 ! 128 bits minimum + bge,pt %icc,.Lenter + sethi %hi(0xffffffff),$mask + retl + clr %o0 +.align 32 +.Lenter: + save %sp,-$frame,%sp + sll $num,2,$num ! num*=4 + or $mask,%lo(0xffffffff),$mask + ld [$n0],$n0 + cmp $ap,$bp + and $num,$mask,$num + ld [$bp],$mul0 ! bp[0] + nop + + add %sp,$bias,%o7 ! real top of stack + ld [$ap],$car0 ! ap[0] ! redundant in squaring context + sub %o7,$num,%o7 + ld [$ap+4],$apj ! ap[1] + and %o7,-1024,%o7 + ld [$np],$car1 ! np[0] + sub %o7,$bias,%sp ! alloca + ld [$np+4],$npj ! np[1] + be,pt `$bits==32?"%icc":"%xcc"`,.Lbn_sqr_mont + mov 12,$j + + mulx $car0,$mul0,$car0 ! ap[0]*bp[0] + mulx $apj,$mul0,$tmp0 !prologue! ap[1]*bp[0] + and $car0,$mask,$acc0 + add %sp,$bias+$frame,$tp + ld [$ap+8],$apj !prologue! + + mulx $n0,$acc0,$mul1 !
