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.

As for choice of MMX/SSE -# in particular, see comment at the end of the file... - -# May 2010 -# -# Add PCLMULQDQ version performing at 2.10 cycles per processed byte. -# The question is how close is it to theoretical limit? The pclmulqdq -# instruction latency appears to be 14 cycles and there can't be more -# than 2 of them executing at any given time. This means that single -# Karatsuba multiplication would take 28 cycles *plus* few cycles for -# pre- and post-processing. Then multiplication has to be followed by -# modulo-reduction. Given that aggregated reduction method [see -# "Carry-less Multiplication and Its Usage for Computing the GCM Mode" -# white paper by Intel] allows you to perform reduction only once in -# a while we can assume that asymptotic performance can be estimated -# as (28+Tmod/Naggr)/16, where Tmod is time to perform reduction -# and Naggr is the aggregation factor. -# -# Before we proceed to this implementation let's have closer look at -# the best-performing code suggested by Intel in their white paper. -# By tracing inter-register dependencies Tmod is estimated as ~19 -# cycles and Naggr chosen by Intel is 4, resulting in 2.05 cycles per -# processed byte. As implied, this is quite optimistic estimate, -# because it does not account for Karatsuba pre- and post-processing, -# which for a single multiplication is ~5 cycles. Unfortunately Intel -# does not provide performance data for GHASH alone. But benchmarking -# AES_GCM_encrypt ripped out of Fig. 15 of the white paper with aadt -# alone resulted in 2.46 cycles per byte of out 16KB buffer. Note that -# the result accounts even for pre-computing of degrees of the hash -# key H, but its portion is negligible at 16KB buffer size. -# -# Moving on to the implementation in question. Tmod is estimated as -# ~13 cycles and Naggr is 2, giving asymptotic performance of ... -# 2.16. How is it possible that measured performance is better than -# optimistic theoretical estimate? There is one thing Intel failed -# to recognize. By serializing GHASH with CTR in same subroutine -# former's performance is really limited to above (Tmul + Tmod/Naggr) -# equation. But if GHASH procedure is detached, the modulo-reduction -# can be interleaved with Naggr-1 multiplications at instruction level -# and under ideal conditions even disappear from the equation. So that -# optimistic theoretical estimate for this implementation is ... -# 28/16=1.75, and not 2.16. Well, it's probably way too optimistic, -# at least for such small Naggr. I'd argue that (28+Tproc/Naggr), -# where Tproc is time required for Karatsuba pre- and post-processing, -# is more realistic estimate. In this case it gives ... 1.91 cycles. -# Or in other words, depending on how well we can interleave reduction -# and one of the two multiplications the performance should be betwen -# 1.91 and 2.16. As already mentioned, this implementation processes -# one byte out of 8KB buffer in 2.10 cycles, while x86_64 counterpart -# - in 2.02. x86_64 performance is better, because larger register -# bank allows to interleave reduction and multiplication better. -# -# Does it make sense to increase Naggr? To start with it's virtually -# impossible in 32-bit mode, because of limited register bank -# capacity. Otherwise improvement has to be weighed agiainst slower -# setup, as well as code size and complexity increase. As even -# optimistic estimate doesn't promise 30% performance improvement, -# there are currently no plans to increase Naggr. -# -# Special thanks to David Woodhouse <dwmw2@infradead.org> for -# providing access to a Westmere-based system on behalf of Intel -# Open Source Technology Centre. - -# January 2010 -# -# Tweaked to optimize transitions between integer and FP operations -# on same XMM register, PCLMULQDQ subroutine was measured to process -# one byte in 2.07 cycles on Sandy Bridge, and in 2.12 - on Westmere. -# The minor regression on Westmere is outweighed by ~15% improvement -# on Sandy Bridge.

Latter means that table size is -# chosen depending on how much data is to be hashed in every given call, -# more data - larger table. Best reported result for Core2 is ~4 cycles -# per processed byte out of 64KB block. This number accounts even for -# 64KB table setup overhead. As discussed in gcm128.c we choose to be -# more conservative in respect to lookup table sizes, but how do the -# results compare? Minimalistic "256B" MMX version delivers ~11 cycles -# on same platform. As also discussed in gcm128.c, next in line "8-bit -# Shoup's" or "4KB" method should deliver twice the performance of -# "256B" one, in other words not worse than ~6 cycles per byte. It -# should be also be noted that in SSE2 case improvement can be "super- -# linear," i.e. more than twice, mostly because >>8 maps to single -# instruction on SSE2 register. This is unlike "4-bit" case when >>4 -# maps to same amount of instructions in both MMX and SSE2 cases. -# Bottom line is that switch to SSE2 is considered to be justifiable -# only in case we choose to implement "8-bit" method... +../openssl/./crypto/modes/asm/ghash-x86.pl

To address this problem (and -# prove that humans are still better than machines:-), the -# original code was overhauled, which resulted in following -# performance changes: -# -# compared with original compared with Intel cc -# assembler impl. generated code -# Pentium -16% +48% -# PIII/AMD +8% +16% -# P4 +85%(!) +45% -# -# As you can see Pentium came out as looser:-( Yet I reckoned that -# improvement on P4 outweights the loss and incorporate this -# re-tuned code to 0.9.7 and later. -# ---------------------------------------------------------------- -# <appro@fy.chalmers.se> - -# August 2009. -# -# George Spelvin has tipped that F_40_59(b,c,d) can be rewritten as -# '(c&d) + (b&(c^d))', which allows to accumulate partial results -# and lighten "pressure" on scratch registers. This resulted in -# >12% performance improvement on contemporary AMD cores (with no -# degradation on other CPUs:-). Also, the code was revised to maximize -# "distance" between instructions producing input to 'lea' instruction -# and the 'lea' instruction itself, which is essential for Intel Atom -# core and resulted in ~15% improvement. - -# October 2010. -# -# Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it -# is to offload message schedule denoted by Wt in NIST specification, -# or Xupdate in OpenSSL source, to SIMD unit. The idea is not novel, -# and in SSE2 context was first explored by Dean Gaudet in 2004, see -# http://arctic.org/~dean/crypto/sha1.html. Since then several things -# have changed that made it interesting again: -# -# a) XMM units became faster and wider; -# b) instruction set became more versatile; -# c) an important observation was made by Max Locktykhin, which made -# it possible to reduce amount of instructions required to perform -# the operation in question, for further details see -# http://software.intel.com/en-us/articles/improving-the-performance-of-the-secure-hash-algorithm-1/. - -# April 2011. -# -# Add AVX code path, probably most controversial... The thing is that -# switch to AVX alone improves performance by as little as 4% in -# comparison to SSSE3 code path. But below result doesn't look like -# 4% improvement... Trouble is that Sandy Bridge decodes 'ro[rl]' as -# pair of µ-ops, and it's the additional µ-ops, two per round, that -# make it run slower than Core2 and Westmere. But 'sh[rl]d' is decoded -# as single µ-op by Sandy Bridge and it's replacing 'ro[rl]' with -# equivalent 'sh[rl]d' that is responsible for the impressive 5.1 -# cycles per processed byte. But 'sh[rl]d' is not something that used -# to be fast, nor does it appear to be fast in upcoming Bulldozer -# [according to its optimization manual]. Which is why AVX code path -# is guarded by *both* AVX and synthetic bit denoting Intel CPUs. -# One can argue that it's unfair to AMD, but without 'sh[rl]d' it -# makes no sense to keep the AVX code path. If somebody feels that -# strongly, it's probably more appropriate to discuss possibility of -# using vector rotate XOP on AMD... - -###################################################################### -# Current performance is summarized in following table.

This is unlike on -# Opteron where compiler-generated code was only 15% behind 32-bit -# assembler, which originally made it hard to motivate the effort. -# There was suggestion to mechanically translate 32-bit code, but I -# dismissed it, reasoning that x86_64 offers enough register bank -# capacity to fully utilize SHA-1 parallelism. Therefore this fresh -# implementation:-) However! While 64-bit code does perform better -# on Opteron, I failed to beat 32-bit assembler on EM64T core. Well, -# x86_64 does offer larger *addressable* bank, but out-of-order core -# reaches for even more registers through dynamic aliasing, and EM64T -# core must have managed to run-time optimize even 32-bit code just as -# good as 64-bit one.

The idea behind it -# is to offload message schedule denoted by Wt in NIST specification, -# or Xupdate in OpenSSL source, to SIMD unit. See sha1-586.pl module -# for background and implementation details. The only difference from -# 32-bit code is that 64-bit code doesn't have to spill @X[] elements -# to free temporary registers. - -# April 2011. -# -# Add AVX code path.

On the -# contrary, 64-bit version, sha512_block, is ~30% *slower* than 32-bit -# sha256_block:-( This is presumably because 64-bit shifts/rotates -# apparently are not atomic instructions, but implemented in microcode. -# -# May 2012. -# -# Optimization including one of Pavel Semjanov's ideas, alternative -# Maj, resulted in >=5% improvement on most CPUs, +20% SHA256 and -# unfortunately -2% SHA512 on P4 [which nobody should care about -# that much]. -# -# June 2012. -# -# Add SIMD code paths, see below for improvement coefficients. SSSE3 -# code path was not attempted for SHA512, because improvement is not -# estimated to be high enough, noticeably less than 9%, to justify -# the effort, not on pre-AVX processors. [Obviously with exclusion -# for VIA Nano, but it has SHA512 instruction that is faster and -# should be used instead.] For reference, corresponding estimated -# upper limit for improvement for SSSE3 SHA256 is 28%. The fact that -# higher coefficients are observed on VIA Nano and Bulldozer has more -# to do with specifics of their architecture [which is topic for -# separate discussion]. -# -# November 2012. -# -# Add AVX2 code path. Two consecutive input blocks are loaded to -# 256-bit %ymm registers, with data from first block to least -# significant 128-bit halves and data from second to most significant. -# The data is then processed with same SIMD instruction sequence as -# for AVX, but with %ymm as operands. Side effect is increased stack -# frame, 448 additional bytes in SHA256 and 1152 in SHA512. - -###################################################################### -# Current performance in cycles per processed byte (less is better): -# -# SHA256 SSSE3 AVX/XOP(*) SHA512 AVX/XOP(*) -# -# AMD K8 14.9 - - 9.57 - -# P4 17.3 - - 30.8 - -# Core 2 15.6 13.8(+13%) - 9.97 - -# Westmere 14.8 12.3(+19%) - 9.58 - -# Sandy Bridge 17.4 14.2(+23%) 11.6(+50%(**)) 11.2 8.10(+38%(**)) -# Ivy Bridge 12.6 10.5(+20%) 10.3(+22%) 8.17 7.22(+13%) -# Haswell 12.2 9.28(+31%) 7.80(+56%) 7.66 5.40(+42%) -# Bulldozer 21.1 13.6(+54%) 13.6(+54%(***)) 13.5 8.58(+57%) -# VIA Nano 23.0 16.5(+39%) - 14.7 - -# Atom 23.0 18.9(+22%) - 14.7 - -# -# (*) whichever best applicable;

Because Linux targets were available first... -# -# In addition the script also "distills" code suitable for GNU -# assembler, so that it can be compiled with more rigid assemblers, -# such as Solaris /usr/ccs/bin/as. -# -# This translator is not designed to convert *arbitrary* assembler -# code from AT&T format to MASM one.

Adhere to Unix register and stack layout [see cross-reference -# ABI "card" at the end for explanation]. -# 2. Forget about "red zone," stick to more traditional blended -# stack frame allocation. If volatile storage is actually required -# that is. If not, just leave the stack as is. -# 3. Functions tagged with ".type name,@function" get crafted with -# unified Win64 prologue and epilogue automatically. If you want -# to take care of ABI differences yourself, tag functions as -# ".type name,@abi-omnipotent" instead. -# 4. To optimize the Win64 prologue you can specify number of input -# arguments as ".type name,@function,N." Keep in mind that if N is -# larger than 6, then you *have to* write "abi-omnipotent" code, -# because >6 cases can't be addressed with unified prologue. -# 5. Name local labels as .L*, do *not* use dynamic labels such as 1: -# (sorry about latter). -# 6. Don't use [or hand-code with .byte] "rep ret." "ret" mnemonic is -# required to identify the spots, where to inject Win64 epilogue! -# But on the pros, it's then prefixed with rep automatically:-) -# 7. Stick to explicit ip-relative addressing.

This poses a problem. It's -# possible to address it by registering custom language-specific -# handler that would restore processor context to the state at -# subroutine entry point and return "exception is not handled, keep -# unwinding" code. Writing such handler can be a challenge... But it's -# doable, though requires certain coding convention. Consider following -# snippet: -# -# .type function,@function -# function: -# movq %rsp,%rax # copy rsp to volatile register -# pushq %r15 # save non-volatile registers -# pushq %rbx -# pushq %rbp -# movq %rsp,%r11 -# subq %rdi,%r11 # prepare [variable] stack frame -# andq $-64,%r11 -# movq %rax,0(%r11) # check for exceptions -# movq %r11,%rsp # allocate [variable] stack frame -# movq %rax,0(%rsp) # save original rsp value -# magic_point: -# ... -# movq 0(%rsp),%rcx # pull original rsp value -# movq -24(%rcx),%rbp # restore non-volatile registers -# movq -16(%rcx),%rbx -# movq -8(%rcx),%r15 -# movq %rcx,%rsp # restore original rsp -# ret -# .size function,.-function -# -# The key is that up to magic_point copy of original rsp value remains -# in chosen volatile register and no non-volatile register, except for -# rsp, is modified. While past magic_point rsp remains constant till -# the very end of the function. In this case custom language-specific -# exception handler would look like this: -# -# EXCEPTION_DISPOSITION handler (EXCEPTION_RECORD *rec,ULONG64 frame, -# CONTEXT *context,DISPATCHER_CONTEXT *disp) -# { ULONG64 *rsp = (ULONG64 *)context->Rax; -# if (context->Rip >= magic_point) -# { rsp = ((ULONG64 **)context->Rsp)[0]; -# context->Rbp = rsp[-3]; -# context->Rbx = rsp[-2]; -# context->R15 = rsp[-1]; -# } -# context->Rsp = (ULONG64)rsp; -# context->Rdi = rsp[1]; -# context->Rsi = rsp[2]; -# -# memcpy (disp->ContextRecord,context,sizeof(CONTEXT)); -# RtlVirtualUnwind(UNW_FLAG_NHANDLER,disp->ImageBase, -# dips->ControlPc,disp->FunctionEntry,disp->ContextRecord, -# &disp->HandlerData,&disp->EstablisherFrame,NULL); -# return ExceptionContinueSearch; -# } -# -# It's appropriate to implement this handler in assembler, directly in -# function's module. In order to do that one has to know members' -# offsets in CONTEXT and DISPATCHER_CONTEXT structures and some constant -# values.

This essentially defines the SEH -# styling rule mentioned in the beginning. Position of this label is -# chosen in such manner that possible exceptions raised in the "gear" -# prologue would be accounted to caller and unwound from latter's frame. -# End of function is marked with respective .LSEH_end_{function_name} -# label. To summarize, .pdata segment would contain -# -# .rva .LSEH_begin_function -# .rva .LSEH_end_function -# .rva function_unwind_info -# -# Reference to function_unwind_info from .xdata segment is the anchor. -# In case you wonder why references are 32-bit .rvas and not 64-bit -# .quads. References put into these two segments are required to be -# *relative* to the base address of the current binary module, a.k.a. -# image base. No Win64 module, be it .exe or .dll, can be larger than -# 2GB and thus such relative references can be and are accommodated in -# 32 bits. -# -# Having reviewed the example function code, one can argue that "movq -# %rsp,%rax" above is redundant. It is not! Keep in mind that on Unix -# rax would contain an undefined value. If this "offends" you, use -# another register and refrain from modifying rax till magic_point is -# reached, i.e. as if it was a non-volatile register. If more registers -# are required prior [variable] frame setup is completed, note that -# nobody says that you can have only one "magic point." You can -# "liberate" non-volatile registers by denoting last stack off-load -# instruction and reflecting it in finer grade unwind logic in handler. -# After all, isn't it why it's called *language-specific* handler... -# -# Attentive reader can notice that exceptions would be mishandled in -# auto-generated "gear" epilogue. Well, exception effectively can't -# occur there, because if memory area used by it was subject to -# segmentation violation, then it would be raised upon call to the -# function (and as already mentioned be accounted to caller, which is -# not a problem). If you're still not comfortable, then define tail -# "magic point" just prior ret instruction and have handler treat it... -# -# (*) Note that we're talking about run-time, not debug-time. Lack of -# unwind information makes debugging hard on both Windows and -# Unix. "Unlike" referes to the fact that on Unix signal handler -# will always be invoked, core dumped and appropriate exit code -# returned to parent (for user notification). +.././openssl/crypto/perlasm/x86_64-xlate.pl
