For further +# details see http://www.openssl.org/~appro/cryptogams/. +# ==================================================================== +# +# Version 4.3. +# +# You might fail to appreciate this module performance from the first +# try. If compared to "vanilla" linux-ia32-icc target, i.e. considered +# to be *the* best Intel C compiler without -KPIC, performance appears +# to be virtually identical... But try to re-configure with shared +# library support... Aha! Intel compiler "suddenly" lags behind by 30% +# [on P4, more on others]:-) And if compared to position-independent +# code generated by GNU C, this code performs *more* than *twice* as +# fast! Yes, all this buzz about PIC means that unlike other hand- +# coded implementations, this one was explicitly designed to be safe +# to use even in shared library context... This also means that this +# code isn't necessarily absolutely fastest "ever," because in order +# to achieve position independence an extra register has to be +# off-loaded to stack, which affects the benchmark result. +# +# Special note about instruction choice. Do you recall RC4_INT code +# performing poorly on P4? It might be the time to figure out why. +# RC4_INT code implies effective address calculations in base+offset*4 +# form. Trouble is that it seems that offset scaling turned to be +# critical path... At least eliminating scaling resulted in 2.8x RC4 +# performance improvement [as you might recall]. As AES code is hungry +# for scaling too, I [try to] avoid the latter by favoring off-by-2 +# shifts and masking the result with 0xFF<<2 instead of "boring" 0xFF. +# +# As was shown by Dean Gaudet <dean@arctic.org>, the above note turned +# void. Performance improvement with off-by-2 shifts was observed on +# intermediate implementation, which was spilling yet another register +# to stack... Final offset*4 code below runs just a tad faster on P4, +# but exhibits up to 10% improvement on other cores. +# +# Second version is "monolithic" replacement for aes_core.c, which in +# addition to AES_[de|en]crypt implements AES_set_[de|en]cryption_key. +# This made it possible to implement little-endian variant of the +# algorithm without modifying the base C code. Motivating factor for +# the undertaken effort was that it appeared that in tight IA-32 +# register window little-endian flavor could achieve slightly higher +# Instruction Level Parallelism, and it indeed resulted in up to 15% +# better performance on most recent µ-archs... +# +# Third version adds AES_cbc_encrypt implementation, which resulted in +# up to 40% performance imrovement of CBC benchmark results. 40% was +# observed on P4 core, where "overall" imrovement coefficient, i.e. if +# compared to PIC generated by GCC and in CBC mode, was observed to be +# as large as 4x:-) CBC performance is virtually identical to ECB now +# and on some platforms even better, e.g. 17.6 "small" cycles/byte on +# Opteron, because certain function prologues and epilogues are +# effectively taken out of the loop... +# +# Version 3.2 implements compressed tables and prefetch of these tables +# in CBC[!] mode. Former means that 3/4 of table references are now +# misaligned, which unfortunately has negative impact on elder IA-32 +# implementations, Pentium suffered 30% penalty, PIII - 10%. +# +# Version 3.3 avoids L1 cache aliasing between stack frame and +# S-boxes, and 3.4 - L1 cache aliasing even between key schedule. The +# latter is achieved by copying the key schedule to controlled place in +# stack.

Firstly, of 256 S-box elements at most 160 +# are referred to in single 128-bit block operation. Well, in C +# implementation with 4 distinct tables it's actually as little as 40 +# references per 256 elements table, but anyway... Secondly, even +# though S-box elements are clustered into smaller amount of cache- +# lines, smaller than 160 and even 40, it turned out that for certain +# plain-text pattern[s] or simply put chosen plain-text and given key +# few cache-lines remain unaccessed during block operation. Now, if +# attacker can figure out this access pattern, he can deduct the key +# [or at least part of it]. The natural way to mitigate this kind of +# attacks is to minimize the amount of cache-lines in S-box and/or +# prefetch them to ensure that every one is accessed for more uniform +# timing. But note that *if* plain-text was concealed in such way that +# input to block function is distributed *uniformly*, then attack +# wouldn't apply. Now note that some encryption modes, most notably +# CBC, do mask the plain-text in this exact way [secure cipher output +# is distributed uniformly]. Yes, one still might find input that +# would reveal the information about given key, but if amount of +# candidate inputs to be tried is larger than amount of possible key +# combinations then attack becomes infeasible. This is why revised +# AES_cbc_encrypt "dares" to switch to larger S-box when larger chunk +# of data is to be processed in one stroke. The current size limit of +# 512 bytes is chosen to provide same [diminishigly low] probability +# for cache-line to remain untouched in large chunk operation with +# large S-box as for single block operation with compact S-box and +# surely needs more careful consideration... +# +# As for asynchronous attacks. There are two flavours: attacker code +# being interleaved with AES on hyper-threading CPU at *instruction* +# level, and two processes time sharing single core. As for latter. +# Two vectors. 1. Given that attacker process has higher priority, +# yield execution to process performing AES just before timer fires +# off the scheduler, immediately regain control of CPU and analyze the +# cache state. For this attack to be efficient attacker would have to +# effectively slow down the operation by several *orders* of magnitute, +# by ratio of time slice to duration of handful of AES rounds, which +# unlikely to remain unnoticed. Not to mention that this also means +# that he would spend correspondigly more time to collect enough +# statistical data to mount the attack. It's probably appropriate to +# say that if adeversary reckons that this attack is beneficial and +# risks to be noticed, you probably have larger problems having him +# mere opportunity. In other words suggested code design expects you +# to preclude/mitigate this attack by overall system security design. +# 2. Attacker manages to make his code interrupt driven. In order for +# this kind of attack to be feasible, interrupt rate has to be high +# enough, again comparable to duration of handful of AES rounds. But +# is there interrupt source of such rate? Hardly, not even 1Gbps NIC +# generates interrupts at such raging rate... +# +# And now back to the former, hyper-threading CPU or more specifically +# Intel P4. Recall that asynchronous attack implies that malicious +# code instruments itself. And naturally instrumentation granularity +# has be noticeably lower than duration of codepath accessing S-box. +# Given that all cache-lines are accessed during that time that is. +# Current implementation accesses *all* cache-lines within ~50 cycles +# window, which is actually *less* than RDTSC latency on Intel P4! + +$0 =~ m/(.*[\/\\])[^\/\\]+$/; $dir=$1; +push(@INC,"${dir}","${dir}../../perlasm"); +require "x86asm.pl"; + +$output = pop; +open OUT,">$output"; +*STDOUT=*OUT; + +&asm_init($ARGV[0],"aes-586.pl",$x86only = $ARGV[$#ARGV] eq "386"); +&static_label("AES_Te"); +&static_label("AES_Td"); + +$s0="eax"; +$s1="ebx"; +$s2="ecx"; +$s3="edx"; +$key="edi"; +$acc="esi"; +$tbl="ebp"; + +# stack frame layout in _[x86|sse]_AES_* routines, frame is allocated +# by caller +$__ra=&DWP(0,"esp"); # return address +$__s0=&DWP(4,"esp"); # s0 backing store +$__s1=&DWP(8,"esp"); # s1 backing store +$__s2=&DWP(12,"esp"); # s2 backing store +$__s3=&DWP(16,"esp"); # s3 backing store +$__key=&DWP(20,"esp"); # pointer to key schedule +$__end=&DWP(24,"esp"); # pointer to end of key schedule +$__tbl=&DWP(28,"esp"); # %ebp backing store + +# stack frame layout in AES_[en|crypt] routines, which differs from +# above by 4 and overlaps by %ebp backing store +$_tbl=&DWP(24,"esp"); +$_esp=&DWP(28,"esp"); + +sub _data_word() { my $i; while(defined($i=shift)) { &data_word($i,$i); } } + +$speed_limit=512; # chunks smaller than $speed_limit are + # processed with compact routine in CBC mode +$small_footprint=1; # $small_footprint=1 code is ~5% slower [on + # recent µ-archs], but ~5 times smaller! + # I favor compact code to minimize cache + # contention and in hope to "collect" 5% back + # in real-life applications... + +$vertical_spin=0; # shift "verticaly" defaults to 0, because of + # its proof-of-concept status... +# Note that there is no decvert(), as well as last encryption round is +# performed with "horizontal" shifts.

Compiler never uses +// variable 'shr' which is pairable with 'extr'/'dep' instructions. +// Then it uses 'zxt' which is an I-type, but can be replaced with +// 'and' which in turn can be assigned to M-port [there're double as +// much M-ports as there're I-ports on Itanium 2]. By sacrificing few +// registers for small constants (255, 24 and 16) to be used with +// 'shr' and 'and' instructions I can achieve better ILP, Instruction +// Level Parallelism, and performance. This code outperforms GCC 3.3 +// generated code by over factor of 2 (two), GCC 3.4 - by 70% and +// HP C - by 40%. Measured best-case scenario, i.e. aligned +// big-endian input, ECB timing on Itanium 2 is (18 + 13*rounds) +// ticks per block, or 9.25 CPU cycles per byte for 128 bit key. + +// Version 1.2 mitigates the hazard of cache-timing attacks by +// a) compressing S-boxes from 8KB to 2KB+256B, b) scheduling +// references to S-boxes for L2 cache latency, c) prefetching T[ed]4 +// prior last round. As result performance dropped to (26 + 15*rounds) +// ticks per block or 11 cycles per byte processed with 128-bit key. +// This is ~16% deterioration.

This is ~16% +# faster than gcc-generated code, which is not very impressive. But +# recall that compressed S-box requires extra processing, namely +# additional rotations. Rotations are implemented with lwl/lwr pairs, +# which is normally used for loading unaligned data. Another cool +# thing about this module is its endian neutrality, which means that +# it processes data without ever changing byte order... + +# September 2012 +# +# Add MIPS32R2 (~10% less instructions) and SmartMIPS ASE (further +# ~25% less instructions) code.

Keep in mind that z-CPUs are +# *strictly* in-order execution and issued instruction [in this case +# load value from memory is critical] has to complete before execution +# flow proceeds. S-boxes are compressed to 2KB[+256B]. +# +# As for hardware acceleration support. It's basically a "teaser," as +# it can and should be improved in several ways. Most notably support +# for CBC is not utilized, nor multiple blocks are ever processed. +# Then software key schedule can be postponed till hardware support +# detection... Performance improvement over assembler is reportedly +# ~2.5x, but can reach >8x [naturally on larger chunks] if proper +# support is implemented. + +# May 2007. +# +# Implement AES_set_[en|de]crypt_key. Key schedule setup is avoided +# for 128-bit keys, if hardware support is detected. + +# Januray 2009. +# +# Add support for hardware AES192/256 and reschedule instructions to +# minimize/avoid Address Generation Interlock hazard and to favour +# dual-issue z10 pipeline. This gave ~25% improvement on z10 and +# almost 50% on z9. The gain is smaller on z10, because being dual- +# issue z10 makes it improssible to eliminate the interlock condition: +# critial path is not long enough. Yet it spends ~24 cycles per byte +# processed with 128-bit key. +# +# Unlike previous version hardware support detection takes place only +# at the moment of key schedule setup, which is denoted in key->rounds. +# This is done, because deferred key setup can't be made MT-safe, not +# for keys longer than 128 bits. +# +# Add AES_cbc_encrypt, which gives incredible performance improvement, +# it was measured to be ~6.6x. It's less than previously mentioned 8x, +# because software implementation was optimized. + +# May 2010. +# +# Add AES_ctr32_encrypt. If hardware-assisted, it provides up to 4.3x +# performance improvement over "generic" counter mode routine relying +# on single-block, also hardware-assisted, AES_encrypt. "Up to" refers +# to the fact that exact throughput value depends on current stack +# frame alignment within 4KB page. In worst case you get ~75% of the +# maximum, but *on average* it would be as much as ~98%. Meaning that +# worst case is unlike, it's like hitting ravine on plateau. + +# November 2010. +# +# Adapt for -m31 build. If kernel supports what's called "highgprs" +# feature on Linux [see /proc/cpuinfo], it's possible to use 64-bit +# instructions and achieve "64-bit" performance even in 31-bit legacy +# application context. The feature is not specific to any particular +# processor, as long as it's "z-CPU". Latter implies that the code +# remains z/Architecture specific. On z990 it was measured to perform +# 2x better than code generated by gcc 4.3. + +# December 2010. +# +# Add support for z196 "cipher message with counter" instruction. +# Note however that it's disengaged, because it was measured to +# perform ~12% worse than vanilla km-based code... + +# February 2011. +# +# Add AES_xts_[en|de]crypt. This includes support for z196 km-xts-aes +# instructions, which deliver ~70% improvement at 8KB block size over +# vanilla km-based code, 37% - at most like 512-bytes block size. + +$flavour = shift;

References to them are scheduled for L2 cache latency, meaning +# that the tables don't have to reside in L1 cache. Once again, this +# is an initial draft and one should expect more countermeasures to +# be implemented... +# +# Version 1.1 prefetches T[ed]4 in order to mitigate attack on last +# round. +# +# Even though performance was not the primary goal [on the contrary, +# extra shifts "induced" by compressed S-box and longer loop epilogue +# "induced" by scheduling for L2 have negative effect on performance], +# the code turned out to run in ~23 cycles per processed byte en-/ +# decrypted with 128-bit key. This is pretty good result for code +# with mentioned qualities and UltraSPARC core. Compared to Sun C +# generated code my encrypt procedure runs just few percents faster, +# while decrypt one - whole 50% faster [yes, Sun C failed to generate +# optimal decrypt procedure].

As SHA256 dominates execution time, +# stitch performance does not depend on AES key length.

For processors that +# can schedule aes[enc|dec] every cycle optimal interleave factor +# equals to corresponding instructions latency. 8x is optimal for +# * Bridge, but it's unfeasible to accommodate such implementation +# in XMM registers addreassable in 32-bit mode and therefore maximum +# of 6x is used instead... + +sub aesni_generate2 +{ my $p=shift; + + &function_begin_B("_aesni_${p}rypt2"); + &$movekey ($rndkey0,&QWP(0,$key)); + &shl ($rounds,4); + &$movekey ($rndkey1,&QWP(16,$key)); + &xorps ($inout0,$rndkey0); + &pxor ($inout1,$rndkey0); + &$movekey ($rndkey0,&QWP(32,$key)); + &lea ($key,&DWP(32,$key,$rounds)); + &neg ($rounds); + &add ($rounds,16); + + &set_label("${p}2_loop"); + eval"&aes${p} ($inout0,$rndkey1)"; + eval"&aes${p} ($inout1,$rndkey1)"; + &$movekey ($rndkey1,&QWP(0,$key,$rounds)); + &add ($rounds,32); + eval"&aes${p} ($inout0,$rndkey0)"; + eval"&aes${p} ($inout1,$rndkey0)"; + &$movekey ($rndkey0,&QWP(-16,$key,$rounds)); + &jnz (&label("${p}2_loop")); + eval"&aes${p} ($inout0,$rndkey1)"; + eval"&aes${p} ($inout1,$rndkey1)"; + eval"&aes${p}last ($inout0,$rndkey0)"; + eval"&aes${p}last ($inout1,$rndkey0)"; + &ret(); + &function_end_B("_aesni_${p}rypt2"); +} + +sub aesni_generate3 +{ my $p=shift; + + &function_begin_B("_aesni_${p}rypt3"); + &$movekey ($rndkey0,&QWP(0,$key)); + &shl ($rounds,4); + &$movekey ($rndkey1,&QWP(16,$key)); + &xorps ($inout0,$rndkey0); + &pxor ($inout1,$rndkey0); + &pxor ($inout2,$rndkey0); + &$movekey ($rndkey0,&QWP(32,$key)); + &lea ($key,&DWP(32,$key,$rounds)); + &neg ($rounds); + &add ($rounds,16); + + &set_label("${p}3_loop"); + eval"&aes${p} ($inout0,$rndkey1)"; + eval"&aes${p} ($inout1,$rndkey1)"; + eval"&aes${p} ($inout2,$rndkey1)"; + &$movekey ($rndkey1,&QWP(0,$key,$rounds)); + &add ($rounds,32); + eval"&aes${p} ($inout0,$rndkey0)"; + eval"&aes${p} ($inout1,$rndkey0)"; + eval"&aes${p} ($inout2,$rndkey0)"; + &$movekey ($rndkey0,&QWP(-16,$key,$rounds)); + &jnz (&label("${p}3_loop")); + eval"&aes${p} ($inout0,$rndkey1)"; + eval"&aes${p} ($inout1,$rndkey1)"; + eval"&aes${p} ($inout2,$rndkey1)"; + eval"&aes${p}last ($inout0,$rndkey0)"; + eval"&aes${p}last ($inout1,$rndkey0)"; + eval"&aes${p}last ($inout2,$rndkey0)"; + &ret(); + &function_end_B("_aesni_${p}rypt3"); +} + +# 4x interleave is implemented to improve small block performance, +# most notably [and naturally] 4 block by ~30%.

All above results are consistently better. This +# module also provides better performance for block sizes smaller than +# 128 bytes in points *not* represented in the above table. +# +# Looking at the results for 8-KB buffer. +# +# CFB and OFB results are far from the limit, because implementation +# uses "generic" CRYPTO_[c|o]fb128_encrypt interfaces relying on +# single-block aesni_encrypt, which is not the most optimal way to go. +# CBC encrypt result is unexpectedly high and there is no documented +# explanation for it. Seemingly there is a small penalty for feeding +# the result back to AES unit the way it's done in CBC mode. There is +# nothing one can do and the result appears optimal. CCM result is +# identical to CBC, because CBC-MAC is essentially CBC encrypt without +# saving output. CCM CTR "stays invisible," because it's neatly +# interleaved wih CBC-MAC. This provides ~30% improvement over +# "straghtforward" CCM implementation with CTR and CBC-MAC performed +# disjointly. Parallelizable modes practically achieve the theoretical +# limit. +# +# Looking at how results vary with buffer size. +# +# Curves are practically saturated at 1-KB buffer size. In most cases +# "256-byte" performance is >95%, and "64-byte" is ~90% of "8-KB" one. +# CTR curve doesn't follow this pattern and is "slowest" changing one +# with "256-byte" result being 87% of "8-KB." This is because overhead +# in CTR mode is most computationally intensive. Small-block CCM +# decrypt is slower than encrypt, because first CTR and last CBC-MAC +# iterations can't be interleaved. +# +# Results for 192- and 256-bit keys. +# +# EVP-free results were observed to scale perfectly with number of +# rounds for larger block sizes, i.e. 192-bit result being 10/12 times +# lower and 256-bit one - 10/14. Well, in CBC encrypt case differences +# are a tad smaller, because the above mentioned penalty biases all +# results by same constant value. In similar way function call +# overhead affects small-block performance, as well as OFB and CFB +# results. Differences are not large, most common coefficients are +# 10/11.7 and 10/13.4 (as opposite to 10/12.0 and 10/14.0), but one +# observe even 10/11.2 and 10/12.4 (CTR, OFB, CFB)... + +# January 2011 +# +# While Westmere processor features 6 cycles latency for aes[enc|dec] +# instructions, which can be scheduled every second cycle, Sandy +# Bridge spends 8 cycles per instruction, but it can schedule them +# every cycle. This means that code targeting Westmere would perform +# suboptimally on Sandy Bridge. Therefore this update. +# +# In addition, non-parallelizable CBC encrypt (as well as CCM) is +# optimized. Relative improvement might appear modest, 8% on Westmere, +# but in absolute terms it's 3.77 cycles per byte encrypted with +# 128-bit key on Westmere, and 5.07 - on Sandy Bridge. These numbers +# should be compared to asymptotic limits of 3.75 for Westmere and +# 5.00 for Sandy Bridge. Actually, the fact that they get this close +# to asymptotic limits is quite amazing. Indeed, the limit is +# calculated as latency times number of rounds, 10 for 128-bit key, +# and divided by 16, the number of bytes in block, or in other words +# it accounts *solely* for aesenc instructions. But there are extra +# instructions, and numbers so close to the asymptotic limits mean +# that it's as if it takes as little as *one* additional cycle to +# execute all of them. How is it possible? It is possible thanks to +# out-of-order execution logic, which manages to overlap post- +# processing of previous block, things like saving the output, with +# actual encryption of current block, as well as pre-processing of +# current block, things like fetching input and xor-ing it with +# 0-round element of the key schedule, with actual encryption of +# previous block. Keep this in mind... +# +# For parallelizable modes, such as ECB, CBC decrypt, CTR, higher +# performance is achieved by interleaving instructions working on +# independent blocks. In which case asymptotic limit for such modes +# can be obtained by dividing above mentioned numbers by AES +# instructions' interleave factor. Westmere can execute at most 3 +# instructions at a time, meaning that optimal interleave factor is 3, +# and that's where the "magic" number of 1.25 come from. "Optimal +# interleave factor" means that increase of interleave factor does +# not improve performance. The formula has proven to reflect reality +# pretty well on Westmere... Sandy Bridge on the other hand can +# execute up to 8 AES instructions at a time, so how does varying +# interleave factor affect the performance? Here is table for ECB +# (numbers are cycles per byte processed with 128-bit key): +# +# instruction interleave factor 3x 6x 8x +# theoretical asymptotic limit 1.67 0.83 0.625 +# measured performance for 8KB block 1.05 0.86 0.84 +# +# "as if" interleave factor 4.7x 5.8x 6.0x +# +# Further data for other parallelizable modes: +# +# CBC decrypt 1.16 0.93 0.74 +# CTR 1.14 0.91 0.74 +# +# Well, given 3x column it's probably inappropriate to call the limit +# asymptotic, if it can be surpassed, isn't it? What happens there? +# Rewind to CBC paragraph for the answer. Yes, out-of-order execution +# magic is responsible for this. Processor overlaps not only the +# additional instructions with AES ones, but even AES instuctions +# processing adjacent triplets of independent blocks. In the 6x case +# additional instructions still claim disproportionally small amount +# of additional cycles, but in 8x case number of instructions must be +# a tad too high for out-of-order logic to cope with, and AES unit +# remains underutilized... As you can see 8x interleave is hardly +# justifiable, so there no need to feel bad that 32-bit aesni-x86.pl +# utilizies 6x interleave because of limited register bank capacity. +# +# Higher interleave factors do have negative impact on Westmere +# performance. While for ECB mode it's negligible ~1.5%, other +# parallelizables perform ~5% worse, which is outweighed by ~25% +# improvement on Sandy Bridge. To balance regression on Westmere +# CTR mode was implemented with 6x aesenc interleave factor. + +# April 2011 +# +# Add aesni_xts_[en|de]crypt. Westmere spends 1.25 cycles processing +# one byte out of 8KB with 128-bit key, Sandy Bridge - 0.90.

Data alignment in parallelizable modes is +# handled with VSX loads and stores, which implies MSR.VSX flag being +# set. It should also be noted that ISA specification doesn't prohibit +# alignment exceptions for these instructions on page boundaries. +# Initially alignment was handled in pure AltiVec/VMX way [when data +# is aligned programmatically, which in turn guarantees exception- +# free execution], but it turned to hamper performance when vcipher +# instructions are interleaved. It's reckoned that eventual +# misalignment penalties at page boundaries are in average lower +# than additional overhead in pure AltiVec approach. +# +# May 2016 +# +# Add XTS subroutine, 9x on little- and 12x improvement on big-endian +# systems were measured. +# +###################################################################### +# Current large-block performance in cycles per byte processed with +# 128-bit key (less is better). +# +# CBC en-/decrypt CTR XTS +# POWER8[le] 3.96/0.72 0.74 1.1 +# POWER8[be] 3.75/0.65 0.66 1.0 + +$flavour = shift; + +if ($flavour =~ /64/) { + $SIZE_T =8; + $LRSAVE =2*$SIZE_T; + $STU ="stdu"; + $POP ="ld"; + $PUSH ="std"; + $UCMP ="cmpld"; + $SHL ="sldi"; +} elsif ($flavour =~ /32/) { + $SIZE_T =4; + $LRSAVE =$SIZE_T; + $STU ="stwu"; + $POP ="lwz"; + $PUSH ="stw"; + $UCMP ="cmplw"; + $SHL ="slwi"; +} else { die "nonsense $flavour"; } + +$LITTLE_ENDIAN = ($flavour=~/le$/) ? $SIZE_T : 0; + +$0 =~ m/(.*[\/\\])[^\/\\]+$/; $dir=$1; +( $xlate="${dir}ppc-xlate.pl" and -f $xlate ) or +( $xlate="${dir}../../perlasm/ppc-xlate.pl" and -f $xlate) or +die "can't locate ppc-xlate.pl"; + +open STDOUT,"| $^X $xlate $flavour ".shift || die "can't call $xlate: $!"; + +$FRAME=8*$SIZE_T; +$prefix="aes_p8"; + +$sp="r1"; +$vrsave="r12"; + +######################################################################### +{{{ #

The +# module is endian-agnostic in sense that it supports both big- and +# little-endian cases. As does it support both 32- and 64-bit modes +# of operation. Latter is achieved by limiting amount of utilized +# registers to 16, which implies additional NEON load and integer +# instructions.

On Cortex-A53, an in-order +# execution core, this costs up to 10-15%, which is partially +# compensated by implementing dedicated code path for 128-bit +# CBC encrypt case.
