###################################################################
#
# September 2011.
#
# Started as transliteration to "perlasm" the original code has
# undergone following changes:
#
# - code was made position-independent;
# - rounds were folded into a loop resulting in >5x size reduction
#   from 12.5KB to 2.2KB;
# - above was possibile thanks to mixcolumns() modification that
#   allowed to feed its output back to aesenc[last], this was
#   achieved at cost of two additional inter-registers moves;
# - some instruction reordering and interleaving;
# - this module doesn't implement key setup subroutine, instead it
#   relies on conversion of "conventional" key schedule as returned
#   by AES_set_encrypt_key (see discussion below);
# - first and last round keys are treated differently, which allowed
#   to skip one shiftrows(), reduce bit-sliced key schedule and
#   speed-up conversion by 22%;
# - support for 192- and 256-bit keys was added;
#
# Resulting performance in CPU cycles spent to encrypt one byte out
# of 4096-byte buffer with 128-bit key is:
#
#		Emilia's	this(*)		difference
#
# Core 2    	9.30		8.69		+7%
# Nehalem(**) 	7.63		6.88		+11%
# Atom	    	17.1		16.4		+4%
# Silvermont	-		12.9
#
# (*)	Comparison is not completely fair, because "this" is ECB,
#	i.e. no extra processing such as counter values calculation
#	and xor-ing input as in Emilia's CTR implementation is
#	performed. However, the CTR calculations stand for not more
#	than 1% of total time, so comparison is *rather* fair.
#
# (**)	Results were collected on Westmere, which is considered to
#	be equivalent to Nehalem for this code.
#
# As for key schedule conversion subroutine. Interface to OpenSSL
# relies on per-invocation on-the-fly conversion. This naturally
# has impact on performance, especially for short inputs. Conversion
# time in CPU cycles and its ratio to CPU cycles spent in 8x block
# function is:
#
# 		conversion	conversion/8x block
# Core 2	240		0.22
# Nehalem	180		0.20
# Atom		430		0.20
#
# The ratio values mean that 128-byte blocks will be processed
# 16-18% slower, 256-byte blocks - 9-10%, 384-byte blocks - 6-7%,
# etc. Then keep in mind that input sizes not divisible by 128 are
# *effectively* slower, especially shortest ones, e.g. consecutive
# 144-byte blocks are processed 44% slower than one would expect,
# 272 - 29%, 400 - 22%, etc. Yet, despite all these "shortcomings"
# it's still faster than ["hyper-threading-safe" code path in]
# aes-x86_64.pl on all lengths above 64 bytes...
#
# October 2011.
#
# Add decryption procedure. Performance in CPU cycles spent to decrypt
# one byte out of 4096-byte buffer with 128-bit key is:
#
# Core 2	9.98
# Nehalem	7.80
# Atom		17.9
# Silvermont	14.0
#
# November 2011.
#
# Add bsaes_xts_[en|de]crypt. Less-than-80-bytes-block performance is
# suboptimal, but XTS is meant to be used with larger blocks...
