Unfortunately, as no stitch implementation # was observed to perform significantly better than the sum of the # components on contemporary CPUs, the effort was deemed impossible to # justify. This module is based on combination of Intel submissions, # [1] and [2], with MOVBE twist suggested by Ilya Albrekht and Max # Locktyukhin of Intel Corp. who verified that it reduces shuffles # pressure with notable relative improvement, achieving 1.0 cycle per # byte processed with 128-bit key on Haswell processor, 0.74 - on # Broadwell, 0.63 - on Skylake... [Mentioned results are raw profiled # measurements for favourable packet size, one divisible by 96. # Applications using the EVP interface will observe a few percent # worse performance.] # # Knights Landing processes 1 byte in 1.25 cycles (measured with EVP). # # [1] http://rt.openssl.org/Ticket/Display.html?id=2900&user=guest&pass=guest # [2] http://www.intel.com/content/dam/www/public/us/en/documents/software-support/enabling-high-performance-gcm.pdf # Generated once from # https://github.com/openssl/openssl/blob/5ffc3324/crypto/modes/asm/aesni-gcm-x86_64.pl # and modified for ICP.
