# register layout taken from Keccak Code Package. It's also as fast,
# in fact faster by 10-15% on some processors, and endian-neutral.
#
+# August 2017.
+#
+# Switch to KECCAK_2X variant for non-NEON code and merge almost 1/2
+# of rotate instructions with logical ones. This resulted in ~10%
+# improvement on most processors. Switch to KECCAK_2X effectively
+# minimizes re-loads from temporary storage, and merged rotates just
+# eliminate corresponding instructions. As for latter. When examining
+# code you'll notice commented ror instructions. These are eliminated
+# ones, and you should trace destination register below to see what's
+# going on. Just in case, why not all rotates are eliminated. Trouble
+# is that you have operations that require both inputs to be rotated,
+# e.g. 'eor a,b>>>x,c>>>y'. This conundrum is resolved by using
+# 'eor a,b,c>>>(x-y)' and then merge-rotating 'a' in next operation
+# that takes 'a' as input. And thing is that this next operation can
+# be in next round. It's totally possible to "carry" rotate "factors"
+# to the next round, but it makes code more complex. And the last word
+# is the keyword, i.e. "almost 1/2" is kind of complexity cap [for the
+# time being]...
