+# SHA256/512 block procedure for PA-RISC.
+
+# June 2009.
+#
+# SHA256 performance is >75% better than gcc 3.2 generated code on
+# PA-7100LC. Compared to code generated by vendor compiler this
+# implementation is almost 70% faster in 64-bit build, but delivers
+# virtually same performance in 32-bit build on PA-8600.
+#
+# SHA512 performance is >2.9x better than gcc 3.2 generated code on
+# PA-7100LC, PA-RISC 1.1 processor. Then implementation detects if the
+# code is executed on PA-RISC 2.0 processor and switches to 64-bit
+# code path delivering adequate peformance even in "blended" 32-bit
+# build. Though 64-bit code is not any faster than code generated by
+# vendor compiler on PA-8600...
