#
# 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]
#vpermq([4][3] [3][1] [2][4] [1][2], 0b01110010)
#vpermq([2][4] [4][3] [1][2] [3][1], 0b00011011) = 0b10001101
# [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

#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:
#
# [0][4] [0][3] [0][2] [0][1]
# [3][0] [1][0] [4][0] [2][0]
#vpermq([3][1] [1][2] [4][3] [2][4], 0b00011011)
# [2][4] [4][3] [1][2] [3][1]
#vpermq([3][4] [1][3] [4][2] [2][1], 0b11100100) = nop :-)
# [3][4] [1][3] [4][2] [2][1]
