	substitute the value of ASM_MARK_NOEXEC_STACK at the end of each
	assembler file.

	* configure.ac (ASM_MARK_NOEXEC_STACK): Check if the C compiler
	generates a .note.GNU-stack section. If so, we should do the same
	in our assembler files.

	changes to the stack frame layout. Patch contributed by Henrik

	* x86/arcfour-crypt.asm: Likewise.
	* x86/aes-encrypt.asm: Likewise.

	* config.m4.in (ELF_STYLE): Substitute configure's ASM_ELF_STYLE.

	* asm.m4 (PROLOGUE, EPILOGUE): New macros, checking the value of

	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.

2005-10-03  Niels Möller  <nisse@lysator.liu.se>

	* x86/sha1-compress.asm (OFFSET): New macro.
	(F3): Eliminated a movl.

	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.

	* sha.h (_nettle_sha1_compress): Changed interface. Second
	argument is now a pointer to the input data in unaligned,
	big-endian form.

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

	* sha1.c (sha1_final): Call sha1_block, don't call the compression

	* configure.ac (RSA_EXAMPLES): Append $(EXEEXT) to the filenames.

2004-03-01  Niels Möller  <nisse@lysator.liu.se>

	* examples/rsa-keygen.c, examples/rsa-encrypt.c,

	* nettle-meta.h (nettle_crypt_func): Typedef moved to cbc.h.
	Include cbc.h instead.

	* cbc.c (cbc_encrypt, cbc_decrypt_internal, cbc_decrypt): Use it

	(SUFFIXES): Added .html.
	(.texinfo.html): Rewrote rule to use a traditional suffix target.
	
	* configure.ac (enable_assembler): Explicitly set
	enable_assembler=no, on architectures where we have no assembler
	files. 
	(ENABLE_ASSEMBLER, ENABLE_SHARED): New automake conditionals.

	* testsuite/testutils.c (xalloc): xalloc(0) should work also on

	* examples/rsa-encrypt-test: Use -r option when invoking
	rsa-encrypt. Needed for the test to work on systems with no
	/dev/urandom.

2004-02-12  Niels Möller  <niels@s3.kth.se>

	* configure.ac (CPPFLAGS, LDFLAGS): No spaces after -I and -L, as
	some C compilers, in particular True64 cc, don't like that.

2004-02-08  Niels Möller  <nisse@lysator.liu.se>

2004-02-07  Niels Möller  <nisse@lysator.liu.se>

	dependency on gmp.h.
	(pgp_put_mpi): Condition on HAVE_LIBGMP.

	* pgp.h: Don't include bignum.h, to make it possible to compile
	the non-bignum parts of pgp-encode.c without bignum support. Needs
	to be fixed properly before the pgp interface is advertised.

	* tools/sexp-conv.c (xalloc): New function.
	(main): Use xalloc.

	* tools/output.c (sexp_put_digest): Use TMP_DECL instead of alloca.

	of alloca, for better portability.

	* examples/io.c (xalloc): New function.

	* Makefile.am (nodist_libnettleinclude_HEADERS): nettle-types.h

	sha1-compress.asm.

	* configure.ac: Use assembler file sha1-compress.asm if available.

	* x86/sha1-compress.asm (EXPAND): Fixed the rotation part of the
	data expansion.

	(BENCH_INTERVAL): Decreased to 0.25s.

	* examples/nettle-benchmark.c (time_function): Loop around calling
	f, until 1s has elapsed. Returns seconds per call. Updated bench
	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
	tries dividing the input into varying size blocks before
	processing. 

	* x86/arcfour-crypt.asm (nettle_arcfour_crypt): Bug fix, half of
	the S array swap was forgotten.
	* arcfour.c (arcfour_stream): Likewise.
	* arcfour-crypt.c (arcfour_crypt): Likewise.

2004-02-05  Niels Möller  <niels@s3.kth.se>

	* x86/arcfour-crypt.asm (nettle_arcfour_crypt): Must store the new
	i, j at the end of the loop.

	* Makefile.am (EXTRA_DIST): Make sure x86 assembler files are
	distributed. 
	(DISTCLEANFILES): And that the symlinks and .s files are deleted.

	* x86/aes-encrypt.asm, x86/aes-decrypt.asm, x86/arcfour-crypt.asm:
	Fixed debug information.

	* x86/arcfour-crypt.asm: New file. About three times faster than
	the optimized C code.

	* configure.ac: Use assembler file arcfour-crypt.asm if available.

	* arcfour.c (arcfour_crypt): Moved function too...
	* arcfour-crypt.c (arcfour_crypt): New file.

	* arcfour.c (arcfour_crypt): Optimization suggested by Jonas
	Walldén. Makes arcfour up to 50% faster on x86 and ppc, and
	probably on other architectures as well.

2004-01-31  Niels Möller  <nisse@lysator.liu.se>

	* configure.ac (AX_CREATE_STDINT_H): Also look for uint32_t and
	friends in sys/types.h.

	comment describing the file format, and moved to rsa-session.h.

	* examples/rsa-decrypt.c (process_file): Finished this function.
	(main): Initialize x. Check the size of the session key after rsa
