+# Keccak-1600 for AVX2.
+#
+# July 2017.
+#
+# To paraphrase Gilles Van Assche, if you contemplate Fig. 2.3 on page
+# 20 of The Keccak reference [or Fig. 5 of FIPS PUB 202], and load data
+# other than A[0][0] in magic order into 6 [256-bit] registers, *each
+# dedicated to one axis*, Pi permutation is reduced to intra-register
+# shuffles...
+#
+# It makes other steps more intricate, but overall, is it a win? To be
+# more specific index permutations organized by quadruples are:
+#
+#       [4][4] [3][3] [2][2] [1][1]<-+
+#       [0][4] [0][3] [0][2] [0][1]<-+
+#       [3][0] [1][0] [4][0] [2][0]  |
+#       [4][3] [3][1] [2][4] [1][2]  |
+#       [3][4] [1][3] [4][2] [2][1]  |
+#       [2][3] [4][1] [1][4] [3][2]  |
+#       [2][2] [4][4] [1][1] [3][3] -+
+#
+# This however is highly impractical for Theta and Chi. What would help
+# Theta is if x indices were aligned column-wise, or in other words:
+#
+#       [0][4] [0][3] [0][2] [0][1]
+#       [3][0] [1][0] [4][0] [2][0]
+#vpermq([4][3] [3][1] [2][4] [1][2], 0b01110010)
+#       [2][4] [4][3] [1][2] [3][1]
+#vpermq([4][2] [3][4] [2][1] [1][3], 0b10001101)
+#       [3][4] [1][3] [4][2] [2][1]
+#vpermq([2][3] [4][1] [1][4] [3][2], 0b01110010)
+#       [1][4] [2][3] [3][2] [4][1]
+#vpermq([1][1] [2][2] [3][3] [4][4], 0b00011011)
+#       [4][4] [3][3] [2][2] [1][1]
+#
+# So here we have it, lines not marked with vpermq() represent the magic
+# order in which data is to be loaded and maintained. [And lines marked
+# with vpermq() represent Pi circular permutation in chosen layout. Note
+# that first step is permutation-free.] A[0][0] is loaded to register of
+# its own, to all lanes. [A[0][0] is not part of Pi permutation or Rho.]
+# Digits in variables' names denote right-most coordinates:
+
+my ($A00,	# [0][0] [0][0] [0][0] [0][0]		# %ymm0
+    $A01,	# [0][4] [0][3] [0][2] [0][1]		# %ymm1
+    $A20,	# [3][0] [1][0] [4][0] [2][0]		# %ymm2
+    $A31,	# [2][4] [4][3] [1][2] [3][1]		# %ymm3
+    $A21,	# [3][4] [1][3] [4][2] [2][1]		# %ymm4
+    $A41,	# [1][4] [2][3] [3][2] [4][1]		# %ymm5
+    $A11) =	# [4][4] [3][3] [2][2] [1][1]		# %ymm6
+    map("%ymm$_",(0..6));
+
+# We also need to map the magic order into offsets within structure:
+
+my @A_jagged = ([0,0], [1,0], [1,1], [1,2], [1,3],	# [0][0..4]
+		[2,2], [6,0], [3,1], [4,2], [5,3],	# [1][0..4]
+		[2,0], [4,0], [6,1], [5,2], [3,3],	# [2][0..4]
+		[2,3], [3,0], [5,1], [6,2], [4,3],	# [3][0..4]
+		[2,1], [5,0], [4,1], [3,2], [6,3]);	# [4][0..4]
+   @A_jagged = map(8*($$_[0]*4+$$_[1]), @A_jagged);	# ... and now linear
+
+# But on the other hand Chi is much better off if y indices were aligned
+# column-wise, not x. For this reason we have to shuffle data prior
+# Chi and revert it afterwards. Prior shuffle is naturally merged with
+# Pi itself:
+#
+#       [0][4] [0][3] [0][2] [0][1]
+#       [3][0] [1][0] [4][0] [2][0]

+#       [3][1] [1][2] [4][3] [2][4]
+#vpermq([4][2] [3][4] [2][1] [1][3], 0b10001101)
+#vpermq([3][4] [1][3] [4][2] [2][1], 0b11100100) = 0b10001101
+#       [3][4] [1][3] [4][2] [2][1]
+#vpermq([2][3] [4][1] [1][4] [3][2], 0b01110010)
+#vpermq([1][4] [2][3] [3][2] [4][1], 0b01110010) = 0b00011011
+#       [3][2] [1][4] [4][1] [2][3]
+#vpermq([1][1] [2][2] [3][3] [4][4], 0b00011011)
+#vpermq([4][4] [3][3] [2][2] [1][1], 0b10001101) = 0b01110010
+#       [3][3] [1][1] [4][4] [2][2]
+#
+# And reverse post-Chi permutation:
