	install-sh when used in tools/Makefile.

	* tools/Makefile.in (INSTALL): Substitute INSTALL, INSTALL_DATA
	and friends here.
	* Makefile.in (INSTALL): Likewise.

2005-11-27  Niels Mller  <nisse@lysator.liu.se>

	executables.

2005-11-24  Niels Mller  <niels@s3.kth.se>

	* examples/nettle-benchmark.c (display): Use two decimal places.

	* sparc/arcfour-crypt.asm: Reorganized. Main loop unrolled four
	times. Uses aligned 32-bit write accesses at DST. Still uses 8-bit
	read accesses at SRC; could be improved int he case that SRC and
	DST have compatible alignment.

2005-10-19  Niels Mller  <niels@s3.kth.se>

	* testsuite/arcfour-test.c (test_main): New testcase with 512
	bytes of data.

2005-10-19  Niels Mller  <nisse@lysator.liu.se>

2005-10-18  Niels Mller  <nisse@lysator.liu.se>

	* sparc/arcfour-crypt.asm: Special unrolled code if SRC and DST
	have compatible alignment. Improves performance by 20%, but I'm
	not sure it's worth the extra complexity.

	* bignum.c (nettle_mpz_from_octets): Removed sign argument. If
	mpz_import is available, define nettle_mpz_from_octets as a macro
	calling mpz_import.
	(nettle_mpz_from_octets): Start by setting x to zero; callers no
	longer need to do that.
	(nettle_mpz_set_str_256_s): New logic for the handling of negative
	numbers. Convert in the same way as for positive numbers, and then
	subtract the appropriate power of two.

2005-10-17  Niels Mller  <nisse@lysator.liu.se>

	* bignum.c (nettle_mpz_from_octets): Improved loop. Removed the
	digit temporary (suggested by Torbjrn Granlund).

	version is now libnettle.so.2.4, soname still libnettle.so.2.

	* examples/nettle-benchmark.c (main): Reordered hash benchmarks.

	* x86/sha1-compress.asm (EXPAND): Use % 16 instead of & 15 to
	compute offsets mod 16, since m4 on FreeBSD 49.RELEASE and NetBSD
	doesn't implement & correctly in eval.

	option is used to say what the clock frequency is.

	* sha1.c (sha1_block): Don't convert data from uint8_t to
	uint32_t, that's now the responsibility of _nettle_sha1_compress.

	argument is now a pointer to the input data in unaligned,
	big-endian form.

2005-09-28  Niels Mller  <niels@s3.kth.se>
