+# SHA256 block transform for x86. September 2007.
+#
+# Performance in clock cycles per processed byte (less is better):

+#		Pentium	PIII	P4	AMD K8	Core2
+# gcc		46	36	41	27	26
+# icc		57	33	38	25	23	
+# x86 asm	40	30	35	20	20
+# x86_64 asm(*)	-	-	21	15.8	16.5
+#
+# (*) x86_64 assembler performance is presented for reference
+#     purposes.
+#
+# Performance improvement over compiler generated code varies from
+# 10% to 40% [see above]. Not very impressive on some µ-archs, but
+# it's 5 times smaller and optimizies amount of writes.
