+! 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

+!
+! 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
