 # May version, >60% over original. Add AVX+shrd code path, >25%
 # improvement on Sandy Bridge over May version, 60% over original.
 #
+# May 2013.
+#
+# Replace AMD XOP code path with SSSE3 to cover more processors.
+# (Biggest improvement coefficient is on upcoming Atom Silvermont,
+# not shown.) Add AVX+BMI code path.
