+# SHA512 block transform for x86. September 2007.
+#
+# Performance in clock cycles per processed byte (less is better):
+#
+#		Pentium	PIII	P4	AMD K8	Core2
+# gcc		100	75	116	54	66
+# icc		97	77	95	55	57
+# x86 asm	61	56	82	36	40
+# SSE2 asm	-	-	38	24	20
+# x86_64 asm(*)	-	-	30	10.0	10.5
+#
+# (*) x86_64 assembler performance is presented for reference
+#     purposes.
+#
+# IALU code-path is optimized for elder Pentiums. On vanilla Pentium
+# performance improvement over compiler generated code reaches ~60%,
+# while on PIII - ~35%. On newer µ-archs improvement varies from 15%
+# to 50%, but it's less important as they are expected to execute SSE2
+# code-path, which is commonly ~2-3x faster [than compiler generated
+# code]. SSE2 code-path is as fast as original sha512-sse2.pl, even
+# though it does not use 128-bit operations. The latter means that
+# SSE2-aware kernel is no longer required to execute the code. Another
+# difference is that new code optimizes amount of writes, but at the
+# cost of increased data cache "footprint" by 1/2KB.
