2002-02-25 Niels Möller <nisse@cuckoo.hack.org>
* sparc/aes.asm (_aes_crypt): Moved increment of src into the
source_loop. Also fixed stop condition, the loop was run 5 times,
not 4, as it should.
(_aes_crypt): Use src directly when accessing the source data,
don't use %o5.
(_aes_crypt): Renamed variables in source_loop.
(_aes_crypt): Changed stop condition in source_loop to not depend
on i. Finally reduced the source_loop to 16 instructions. Also
increased the alignment of the code to 16.
(_aes_crypt): In final_loop, use preshifted indices.
(_aes_crypt): In final_loop, construct the result in t0. Use t0-t3
for intermediate values.
(_aes_crypt): In final_loop, use the register idx.
(_aes_crypt): In final_loop, keep i multiplied by 4. Use key to
get to the current roundkey.
(_aes_crypt): In final_loop, use i for indexing.
(_aes_crypt): Update dst in the output loop. This yields a delay
slot that isn't filled yet.
(_aes_crypt): Decrement round when looping, saving yet some
instructions.
(_aes_crypt): Reformatted code as blocks of four instructions
each.
(_aes_crypt): Copy the addresses of the indexing tables into
registers at the start. No more need for the idx register.
(_aes_crypt): Deleted idx register.
(_aes_crypt): Some peep hole optimizations, duplicating some
instructions to fill nop:s, and put branch instructions on even
word addresses.
2002-02-22 Niels Möller <nisse@cuckoo.hack.org>
* sparc/aes.asm (_aes_crypt): Moved some more additions out of the
inner loop, using additional registers.

using the subkey pointer.
2002-02-19 Niels Möller <nisse@cuckoo.hack.org>

2002-02-16 Niels Möller <nisse@cuckoo.hack.org>
* sparc/aes.asm: Use that IDX2(j) == j ^ 2
* Makefile.am (libnettle_a_SOURCES): Reordered aes-decrypt.c and
aes-encrypt.c. For some strange reason it makes the benchmark go
faster...
* sparc/aes.asm (_aes_crypt): Use double-buffering, and no
separate loop for adding the round key.
(round): Keep round index muliplied by 16, so it can be used
directly for indexing the subkeys.
(_aes_crypt): In the final loop, use ctx+round to access the
subkeys, no need for an extra register.
2002-02-15 Niels Möller <nisse@cuckoo.hack.org>
* sparc/aes.asm (_aes_crypt): Renaming variables, allocating
locals starting from %l0.
(_aes_crypt): Consistently use %l4, aka i, as the variable for the
innermost loops.
(_aes_crypt): Moved reading of ctx->nrounds out of the loop.
(_aes_crypt): In final_loop, deleted a redundant mov, and use i as
loop variable.
(_aes_crypt): Started renumbering registers in the inner loop. The
computation for the table[j] sub-expression should be kept in
register %o[j].
(_aes_crypt): Renamed more variables in the inner loop. Now the
primary variables are t0, t1, t2, t3.
* sparc/aes.asm (_aes_crypt): Swapped register %i0 and %o5, %i1
and %o0, %i2 and %o4, %i3 and %o3, %i4 and %o2.
(_aes_crypt): wtxt was stored in both %l1 and %l2 for the entire
function. Freed %l2 for other uses.
(_aes_crypt): Likewise for tmp, freeing register %o1.
* sparc/machine.m4: New file, for sparc-specific macros.
* sparc/aes.asm (_aes_crypt): Hacked the source_loop, to get rid
of yet another redundant loop variable, and one instruction.
(_aes_crypt): Strength reduce loop variable in the
inner loop, getting rid of one register.
(_aes_crypt): Use pre-shifted indices (aes_table.idx_shift), to
avoid some shifts in the inner loop.
(_aes_crypt): Don't check for nrounds==0 at the start of the loop.
* asm.m4: Define and use structure-defining macros.
* Makefile.am (%.asm): Use a GNU pattern rule, to make %.o depend
on both %.asm and asm.m4.
* aes-internal.h (struct aes_table): New subtable idx_shift.
Updated tables in aes_encrypt.c and aes_decrypt.c.
* asm.m4: Use eval to compute values.
* sparc/aes.asm (_aes_crypt): Deleted commented out old version of
the code.
* asm.m4: Added constants for individual rows of the aes table.

structure of the idx table.

* testsuite/cbc-test.c (test_cbc_bulk): Use aes_set_encrypt_key
and aes_set_decrypt_key.
* sparc/aes.asm (_aes_crypt): Use symbolic names for the fucntion
arguments.
2002-02-14 Niels Möller <nisse@cuckoo.hack.org>
* sparc/aes.asm: Copied gcc assembler code for _aes_crypt.
* aesdata.c: New program for generating AES-related tables.
* testsuite/testutils.c (print_hex): New function (moved from
yarrow-test.c).
* testsuite/rsa-keygen-test.c (progress): Declare the ctx argument
as UNUSED.

* yarrow256.c: Replaced uses of aes_set_key with
aes_set_encrypt_key.
* nettle-meta.h (_NETTLE_CIPHER_SEP): New macro, useful for
algorithms with separate encyption and decryption key setup.
* aes-internal.h (struct aes_table): New structure, including all
constant tables needed by the unified encryption or decryption
function _aes_crypt.
* aes.c (_aes_crypt): New function, which unifies encryption and
decryption.
AES key setup now uses two separate functions for setting
encryption and decryption keys. Applications that don't do
decryption need no inverted subkeys and no code to generate them.
Similarly, the tables (about 4K each for encryption and
decryption), are put into separate files.
* aes.h (struct aes_ctx): Deleted space for inverse subkeys. For
decryption, the inverse subkeys replace the normal subkeys, and
they are stored _in the order they are used_.
* aes-set-key.c (aes_set_key): Deleted file, code moved...
* aes-set-decrypt-key.c, aes-set-encrypt-key.c: New files,
separated normal and inverse key setup.
* aes-tables.c: Deleted, tables moved elsewhere...
* aes-encrypt.c, aes-decrypt.c: New files; moved encryption and
decryption funktions, and needed tables, into separate files.
2002-02-13 Niels Möller <nisse@cuckoo.hack.org>
* 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.
2002-02-12 Niels Möller <nisse@cuckoo.hack.org>
* 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.

* cbc.c (cbc_decrypt_internal): New function, doing the real CBC
procesing and requiring that src != dst.
(cbc_decrypt): Use cbc_decrypt_internal. If src == dst, use a
buffer of limited size to copy the ciphertext.
* nettle-internal.c (nettle_blowfish128): Fixed definition, with
key size in bits.
* nettle-meta.h (_NETTLE_CIPHER_FIX): New macro, suitable for
ciphers with a fixed key size.
* examples/nettle-benchmark.c (display): New function for
displaying the results, including MB/s figures.
