!
! June 8, 2000.
!
! Version 2.0. 32/64-bit, PIC-ification, blended CPU adaptation
! by Andy Polyakov.
!
! January 1, 2003.
!
! Assembler version: Copyright Svend Olaf Mikkelsen.

!
! This code can be freely used by LibDES/SSLeay/OpenSSL users.

!
! To expand the m4 macros: m4 -B 8192 des_enc.m4 > des_enc.S
!
! Global registers 1 to 5 are used. This is the same as done by the

! Macro definitions:
! {ip_macro}
!
! The logic used in initial and final permutations is the same as in
! the C code. The permutations are done with a clever shift, xor, and
! technique.
!
! The macro also loads address sbox 1 to 5 to global 1 to 5, address
! sbox 6 to local6, and addres sbox 8 to out3.
!
! Rotates the halfs 3 left to bring the sbox bits in convenient positions.
!
! Loads key first round from address in parameter 5 to out0, out1.
!
! After the the original LibDES initial permutation, the resulting left
! is in the variable initially used for right and vice versa. The macro
! implements the possibility to keep the halfs in the original registers.
!
! parameter 1 left
! parameter 2 right
! parameter 3 result left (modify in first round)
! parameter 4 result right (use in first round)
! parameter 5 key address
! parameter 6 1/2 for include encryption/decryption
! parameter 7 1 for move in1 to in3
! parameter 8 1 for move in3 to in4, 2 for move in4 to in3
! parameter 9 1 for load ks3 and ks2 to in4 and in3

! {rounds_macro}
!
! The logic used in the DES rounds is the same as in the C code,
! except that calculations for sbox 1 and sbox 5 begin before
! the previous round is finished.
!
! In each round one half (work) is modified based on key and the
! other half (use).
!
! In this version we do two rounds in a loop repeated 7 times
! and two rounds seperately.
!
! One half has the bits for the sboxes in the following positions:
!
! 777777xx555555xx333333xx111111xx
!
! 88xx666666xx444444xx222222xx8888
!
! The bits for each sbox are xor-ed with the key bits for that box.
! The above xx bits are cleared, and the result used for lookup in
! the sbox table. Each sbox entry contains the 4 output bits permuted
! into 32 bits according to the P permutation.
!
! In the description of DES, left and right are switched after
! each round, except after last round. In this code the original
! left and right are kept in the same register in all rounds, meaning
! that after the 16 rounds the result for right is in the register
! originally used for left.
!
! parameter 1 first work (left in first round)
! parameter 2 first use (right in first round)
! parameter 3 enc/dec 1/-1
! parameter 4 loop label
! parameter 5 key address register
! parameter 6 optional address for key next encryption/decryption
! parameter 7 not empty for include retl
!
! also compares in2 to 8
