+# This is AESNI-CBC+SHA256 stitch implementation. The idea, as spelled
+# in http://download.intel.com/design/intarch/papers/323686.pdf, is
+# that since AESNI-CBC encrypt exhibit *very* low instruction-level
+# parallelism, interleaving it with another algorithm would allow to
+# utilize processor resources better and achieve better performance.
+# SHA256 instruction sequences(*) are taken from sha512-x86_64.pl and
+# AESNI code is weaved into it. As SHA256 dominates execution time,
+# stitch performance does not depend on AES key length. Below are
+# performance numbers in cycles per processed byte, less is better,
+# for standalone AESNI-CBC encrypt, standalone SHA256, and stitched
+# subroutine:
+#
+# AES-128/-192/-256+SHA256 this(**)gain
+# Sandy Bridge 5.05/6.05/7.05+11.6 13.0 +28%/36%/43%

+# Bulldozer 5.77/6.89/8.00+13.7 13.7 +42%/50%/58%
+#
+# (*) there are XOP, AVX1 and AVX2 code pathes, meaning that
+# Westmere is omitted from loop, this is because gain was not
+# estimated high enough to justify the effort;
+# (**) these are EVP-free results, results obtained with 'speed
+# -evp aes-256-cbc-hmac-sha256' will vary by percent or two;
