-# Specific modes implementations for SPARC Architecture 2011. There
-# is T4 dependency though, an ASI value that is not specified in the
-# Architecture Manual. But as SPARC universe is rather monocultural,
-# we imply that processor capable of executing crypto instructions
-# can handle the ASI in question as well. This means that we ought to
-# keep eyes open when new processors emerge...
-#
-# As for above mentioned ASI. It's so called "block initializing
-# store" which cancels "read" in "read-update-write" on cache lines.
-# This is "cooperative" optimization, as it reduces overall pressure
-# on memory interface. Benefits can't be observed/quantified with
-# usual benchmarks, on the contrary you can notice that single-thread
-# performance for parallelizable modes is ~1.5% worse for largest
-# block sizes [though few percent better for not so long ones]. All
-# this based on suggestions from David Miller.
