# Keccak-1600 for AVX-512F.
#
# July 2017.
#
# Below code is KECCAK_1X_ALT implementation (see sha/keccak1600.c).
# Pretty straightforward, the only "magic" is data layout in registers.
# It's impossible to have one that is optimal for every step, hence
# it's changing as algorithm progresses. Data is saved in order that
# benefits Chi, but at the same time is easily convertible to order
# that benefits Theta. Conversion from Chi layout to Theta is
# explicit and reverse one is kind of fused with Pi...

########################################################################
# Coordinates below correspond to those in sha/keccak1600.c. Layout
# suitable for Chi is one with y coordinates aligned column-wise. Trick
# is to add regular shift to x coordinate, so that Chi can still be
# performed with as little as 7 instructions, yet be converted to layout
# suitable for Theta with intra-register permutations alone. Here is
# "magic" layout for Chi (with pre-Theta shuffle):
#
# [4][4] [3][3] [2][2] [1][1] [0][0]>4.3.2.1.0>[4][4] [3][3] [2][2] [1][1] [0][0]
# [4][0] [3][4] [2][3] [1][2] [0][1]>3.2.1.0.4>[3][4] [2][3] [1][2] [0][1] [4][0]
# [4][1] [3][0] [2][4] [1][3] [0][2]>2.1.0.4.3>[2][4] [1][3] [0][2] [4][1] [3][0]
# [4][2] [3][1] [2][0] [1][4] [0][3]>1.0.4.3.2>[1][4] [0][3] [4][2] [3][1] [2][0]
# [4][3] [3][2] [2][1] [1][0] [0][4]>0.4.3.2.1>[0][4] [4][3] [3][2] [2][1] [1][0]
#
# Layout suitable to Theta has x coordinates aligned column-wise
# [it's interleaved with Pi indices transformation for reference]:
#
# [4][4] [3][3] [2][2] [1][1] [0][0] $A00
##[0][4] [0][3] [0][2] [0][1] [0][0]
# [3][4] [2][3] [1][2] [0][1] [4][0] $A01
##[2][3] [2][2] [2][1] [2][0] [2][4]
# [2][4] [1][3] [0][2] [4][1] [3][0] $A02
##[4][2] [4][1] [4][0] [4][4] [4][3]
# [1][4] [0][3] [4][2] [3][1] [2][0] $A03
##[1][1] [1][0] [1][4] [1][3] [1][2]
# [0][4] [4][3] [3][2] [2][1] [1][0] $A04
##[3][0] [3][4] [3][3] [3][2] [3][1]
#
# Pi itself is performed by blending above data and finally shuffling it
# to original Chi layout:
#
# [1][1] [2][2] [3][3] [4][4] [0][0]>1.2.3.4.0>[4][4] [3][3] [2][2] [1][1] [0][0]
# [2][3] [3][4] [4][0] [0][1] [1][2]>2.3.4.0.1>[4][0] [3][4] [2][3] [1][2] [0][1]
# [3][0] [4][1] [0][2] [1][3] [2][4]>3.4.0.1.2>[4][1] [3][0] [2][4] [1][3] [0][2]
# [4][2] [0][3] [1][4] [2][0] [3][1]>4.0.1.2.3>[4][2] [3][1] [2][0] [1][4] [0][3]
# [0][4] [1][0] [2][1] [3][2] [4][3]>0.1.2.3.4>[4][3] [3][2] [2][1] [1][0] [0][4]
#
# As implied, data is loaded in Chi layout. Digits in variables' names
