+# SHA512 block procedure for ARMv4. September 2007.

+# This code is ~4.5 (four and a half) times faster than code generated

+
+# Byte order [in]dependence. =========================================
+#
+# Caller is expected to maintain specific *dword* order in h[0-7],
+# namely with most significant dword at *lower* address, which is
+# reflected in below two parameters. *Byte* order within these dwords
+# in turn is whatever *native* byte order on current platform.
