ChangeLog

+2002-02-12  Niels Mller  <nisse@cuckoo.hack.org>
+
+	* sparc/aes.asm (aes_encrypt): Strength reduced on j, getting rid
+	of one register and one instruction in the inner loop.
+
+	* sparc/aes.asm (idx, aes_encrypt): Multiplied tabled values by 4,
+	making it possible to get rid of some shifts in the inner loop.
+
+	* configure.in: Fixed spelling of --enable-assembler. Commented
+	out debug echo:s.
+
+	* asm.m4: New file. For now, only doing changequote and changecom.  
+
+	* sparc/aes.asm (aes_encrypt): Added comments.
+	(aes_encrypt): Cut off redundant instruction per block, also
+	saving one redundant register pointing to idx.
+	(idx_row): New macro. Include asm.m4.
+
+2002-02-11  Niels Mller  <nisse@cuckoo.hack.org>
+
+	* sparc/aes.asm (key_addition_8to32): Cleaned up.
+	Deleted gcc-generated debugging information.
+
+	* sparc/aes.asm (key_addition32): First attempt at optimization.
+	Made it slower ;-)
+
+	* sparc/aes.asm (key_addition32): Unrolled loop, gained 4%
+	speed, payed four instructions compared to gcc
+	generated code. 
+	
+	* Makefile.am (.asm.o): New rule for assembling via m4.
+	(libnettle_a_SOURCES): Added new rsa and aes files.
+
+	* configure.in: New command line option --enable-assembler.
+	Selects assembler code depending on the host system.
+
+	* rsa-decrypt.c, rsa-encrypt.c: New files for rsa pkcs#1
+	encryption. 
+
+	* aes-set-key.c, aes-tables.c: New files, split off from aes.c.
+	Tables are now not static, but use a _aes_ prefix on their names. 
+
+	* aes-internal.h: New file.
+
+	* cast128-meta.c (_NETTLE_CIPHER_FIX): Use _NETTLE_CIPHER_FIX. 
+
+	* 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.
+
+	* sparc/aes.asm: New file. Not yet tuned in any way (it's just the
+	code generated by gcc).
