# 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.

# Purpose of these subroutines is to explicitly encode VIS instructions,

# extentions on compiler command line, e.g. -xarch=v9 vs. -xarch=v9a.
# Idea is to reserve for option to produce "universal" binary and let
# programmer detect if current CPU is VIS capable at run-time.
