	precomputing the offset between src and dst.

	* tools/Makefile.in (.c.$(OBJEXT)): Removed redundant -I.. flag.

	* x86/arcfour-crypt.asm (nettle_arcfour_crypt): Replaced addb ->

	functions to not loop themselves.
	(display): Updated MB/s calculation.

	* testsuite/arcfour-test.c (test_main): Use test_cipher_stream.

	* testsuite/testutils.c (test_cipher_stream): New function, that

2003-09-21  Niels Mller  <nisse@cuckoo.hack.org>

	* testsuite/rsa-encrypt-test.c (test_main): Don't use gmp_printf,

	nettle_des_set_key for referring to Nettle's function.

	not replace it.

	* sparc/aes.asm: (_aes_crypt): Restore %fp at end of function, to

	* x86/machine.m4 (AES_SUBST_BYTE): New macro.

	* sparc/aes.asm: wtxt needs no register of it's own, as its

	allocated for wtxt, so that we stay clean of the reserved %g
	registers.

2002-05-14  Niels Mller  <nisse@cuckoo.hack.org>

	encrypt more than one block at a time.

2002-05-07  Niels Mller  <niels@s3.kth.se>
