| 17 | # "[Re]written" was achieved in two major overhauls. In 2004 BODY_*
|
|---|
| 18 | # functions were re-implemented to address P4 performance issue [see
|
|---|
| 19 | # commentary below], and in 2006 the rest was rewritten in order to
|
|---|
| 20 | # gain freedom to liberate licensing terms.

|

| 22 | # January, September 2004.
|
|---|
| 23 | #
|
|---|
| 24 | # It was noted that Intel IA-32 C compiler generates code which
|
|---|
| 25 | # performs ~30% *faster* on P4 CPU than original *hand-coded*
|
|---|
| 26 | # SHA1 assembler implementation. To address this problem (and
|
|---|
| 27 | # prove that humans are still better than machines:-), the
|
|---|
| 28 | # original code was overhauled, which resulted in following
|
|---|
| 29 | # performance changes:
|
|---|
| 30 | #
|
|---|
| 31 | # compared with original compared with Intel cc
|
|---|
| 32 | # assembler impl. generated code
|
|---|
| 33 | # Pentium -16% +48%
|
|---|
| 34 | # PIII/AMD +8% +16%
|
|---|
| 35 | # P4 +85%(!) +45%
|
|---|
| 36 | #
|
|---|
| 37 | # As you can see Pentium came out as looser:-( Yet I reckoned that
|
|---|
| 38 | # improvement on P4 outweighs the loss and incorporate this
|
|---|
| 39 | # re-tuned code to 0.9.7 and later.
|

|
|---|
| 44 | # George Spelvin has tipped that F_40_59(b,c,d) can be rewritten as
|
|---|
| 45 | # '(c&d) + (b&(c^d))', which allows to accumulate partial results
|
|---|
| 46 | # and lighten "pressure" on scratch registers. This resulted in
|
|---|
| 47 | # >12% performance improvement on contemporary AMD cores (with no
|
|---|
| 48 | # degradation on other CPUs:-). Also, the code was revised to maximize
|
|---|
| 49 | # "distance" between instructions producing input to 'lea' instruction
|
|---|
| 50 | # and the 'lea' instruction itself, which is essential for Intel Atom
|
|---|
| 51 | # core and resulted in ~15% improvement.
|
|---|
| 52 |
|
|---|
| 53 | # October 2010.
|
|---|
| 54 | #
|
|---|
| 55 | # Add SSSE3, Supplemental[!] SSE3, implementation. The idea behind it
|
|---|
| 56 | # is to offload message schedule denoted by Wt in NIST specification,
|
|---|
| 57 | # or Xupdate in OpenSSL source, to SIMD unit. The idea is not novel,
|
|---|
| 58 | # and in SSE2 context was first explored by Dean Gaudet in 2004, see
|
|---|
| 59 | # http://arctic.org/~dean/crypto/sha1.html. Since then several things
|
|---|
| 60 | # have changed that made it interesting again:
|
|---|
| 61 | #
|
|---|
| 62 | # a) XMM units became faster and wider;
|
|---|
| 63 | # b) instruction set became more versatile;
|
|---|
| 64 | # c) an important observation was made by Max Locktykhin, which made
|
|---|
| 65 | # it possible to reduce amount of instructions required to perform
|
|---|
| 66 | # the operation in question, for further details see
|
|---|
| 67 | # http://software.intel.com/en-us/articles/improving-the-performance-of-the-secure-hash-algorithm-1/.

|
|---|
| 70 | #
|
|---|
| 71 | # Add AVX code path, probably most controversial... The thing is that
|
|---|
| 72 | # switch to AVX alone improves performance by as little as 4% in
|
|---|
| 73 | # comparison to SSSE3 code path. But below result doesn't look like
|
|---|
| 74 | # 4% improvement... Trouble is that Sandy Bridge decodes 'ro[rl]' as
|
|---|
| 75 | # pair of µ-ops, and it's the additional µ-ops, two per round, that
|
|---|
| 76 | # make it run slower than Core2 and Westmere. But 'sh[rl]d' is decoded
|
|---|
| 77 | # as single µ-op by Sandy Bridge and it's replacing 'ro[rl]' with
|
|---|
| 78 | # equivalent 'sh[rl]d' that is responsible for the impressive 5.1
|
|---|
| 79 | # cycles per processed byte. But 'sh[rl]d' is not something that used
|
|---|
| 80 | # to be fast, nor does it appear to be fast in upcoming Bulldozer
|
|---|
| 81 | # [according to its optimization manual]. Which is why AVX code path
|
|---|
| 82 | # is guarded by *both* AVX and synthetic bit denoting Intel CPUs.
|
|---|
| 83 | # One can argue that it's unfair to AMD, but without 'sh[rl]d' it
|
|---|
| 84 | # makes no sense to keep the AVX code path. If somebody feels that
|
|---|
| 85 | # strongly, it's probably more appropriate to discuss possibility of
|
|---|
| 86 | # using vector rotate XOP on AMD...
|
|---|
| 87 |
|
|---|
| 88 | # March 2014.
|
|---|
| 89 | #
|
|---|
| 90 | # Add support for Intel SHA Extensions.
