+       * aes.c (aes_encrypt): Don't unroll the innerloop.
+       (aes_encrypt): Don't unroll the loop for the final round.
+       (aes_decrypt): Likewise, no loop unrolling.
+
+       * aes-set-key.c (aes_set_key): Reversed the order of the inverted
+       subkeys. They are now stored in the same order as they are used.
+
+       * aes-tables.c (itable): New bigger table, generated by aesdata.c. 
+
+       * aes.c (aes_decrypt): Rewrote to use the bigger tables.

+       * aes.c (aes_encrypt): Interleave computation and output in the
+       final round.
+
+       * aes-internal.h (AES_SMALL): New macro.
+
+       * aes.c (aes_encrypt): Optionally use smaller rotating inner loop.
+
+       * aes-tables.c (dtbl): Replaced with table generated by aesdata.
+
+       * aes.c (aes_encrypt): Rewrite, now uses larger tables in order to
+       avoid rotates.
+
        * sparc/aes.asm (aes_encrypt): Strength reduced on j, getting rid
        of one register and one instruction in the inner loop.
