	* fftw/fftwf77.c, rfftw/rfftwf77.c, threads/fftw_f77_threads.c,
	threads/rfftw_f77_threads.c: whoops, missing Fortran wrappers,
	grr...thanks to Stuart Midgley

2003-03-15  Steven G. Johnson  <stevenj@ab-initio>

	* fftw/fftw.h.in: removed C99 complex stuff, since it breaks
	backwards compatibility

2003-03-08  Steven G. Johnson  <stevenj@ab-initio>

	* configure.in, acinclude.m4: warnings only in debug/maintainer
	mode

2003-01-15  Steven G. Johnson  <stevenj@ab-initio>

	* doc/fftw.texi: fixed typo (thanks to Andrew Young for the
	correction)

	* mpi/Makefile.am: whoops

	* acx_mpi.m4: added

	* FAQ/fftw-faq.bfnn: more FAQs

	* acinclude.m4, configure.in, fftw/config.h.in, fftw/f77_func.h,
	fftw/fftwf77.c, mpi/fftw_f77_mpi.h, rfftw/rfftwf77.c,
	threads/fftw_f77_threads.c, threads/rfftw_f77_threads.c: use
	autoconf's AC_F77_WRAPPERS instead of our own mangling code...the
	autoconf stuff is derived from ours, anyway

2002-10-24  Steven G. Johnson  <stevenj@ab-initio>

	* NEWS, configure.in: use acx_mpi.m4

	* mpi/Makefile.am: whoops

	* acx_mpi.m4: added

	* FAQ/fftw-faq.bfnn: more FAQs

	* acinclude.m4, configure.in, fftw/config.h.in, fftw/f77_func.h,
	fftw/fftwf77.c, mpi/fftw_f77_mpi.h, rfftw/rfftwf77.c,
	threads/fftw_f77_threads.c, threads/rfftw_f77_threads.c: use
	autoconf's AC_F77_WRAPPERS instead of our own mangling code...the
	autoconf stuff is derived from ours, anyway

	* configure.in: bumped version

	* gensrc/Makefile.fftw.am, gensrc/Makefile.rfftw.am: whoops

	* acinclude.m4, configure.in, gensrc/Makefile.fftw.am,
	gensrc/Makefile.rfftw.am, mpi/Makefile.am, tests/Makefile.am,
	threads/Makefile.am: eliminated SUBST_XXX hackery...it doesn't
	work with the latest autoconf, and doesn't seem to be needed any
	more either

	* acx_pthread.m4: sync with fftw3

2002-07-12  Steven G. Johnson  <stevenj@ab-initio>

	not work)

2001-04-21  Steven G. Johnson  <stevenj@fftw.org>

	* fortran/f77_test.F: more compilation notes

2001-04-01  fftw  <fftw@fftw.org>

	* acinclude.m4: Use -O3 instead of -O6 with gcc.  -O6 isn't a real
	flag anyway, and it is not recognized by some versions of gcc
	(notably, Apple's hacked-up version on MacOS X).

2001-03-08  fftw  <fftw@fftw.org>

	* acx_pthread.m4: check for -mt *after* -lpthread. -mt links only
	-lthread, but this sometimes mysteriously works, and I don't want
	to link in more than I have to or rely on something which seems to
	be undocumented(?).

2001-02-16  fftw  <fftw@fftw.org>

	* configure.in: Steven Berukoff reports that -lmpich is needed,
	even with mpicc, for some MPI installations.

2000-12-30  fftw  <fftw@fftw.org>

	* acx_pthread.m4: minor comment fix

	* acx_pthread.m4: clarified -mt effects

2000-12-21  Steven G. Johnson  <stevenj@fftw.org>

	* acx_pthread.m4: not sure if -mt uses -lpthread...

	* acx_pthread.m4: added -mt flag

2000-12-09  fftw  <fftw@fftw.org>

	* acx_pthread.m4: fixed position of AC_REQUIRE

	* FAQ/fftw-faq.bfnn: addressed finite-precision floating-point in
	FAQ

2000-10-22  fftw  <fftw@fftw.org>

	* acx_pthread.m4: fixed comment

	* gensrc/genfft.ml, gensrc/symmetry.ml: whoops, undo accidental
	commit

	* acx_pthread.m4, gensrc/genfft.ml, gensrc/symmetry.ml: many
	changes

2000-10-16  fftw  <fftw@fftw.org>

	* doc/fftw.texi: point rfftw users to fftw for prime sizes

2000-10-04  fftw  <fftw@fftw.org>

	* acinclude.m4: newer xlc versions reportedly accept -qarch=auto
	to automatically tune for the native host.

2000-07-03  fftw  <fftw@fftw.org>

	* acinclude.m4: Punt on guessing -qarch/-qtune flags for AIX,
	since there seems to be no good way to guess the CPU.

2000-06-26  Matteo Frigo  <athena@fftw.org>

	* fftw/fftwnd.c: Unrolled loop to expose more parallelism.

2000-06-07  fftw  <fftw@fftw.org>

	* configure.in: Added "mpcc" MPI compiler for IBM SP3.  thanks to
	Ferenc Molnar for the information.

2000-06-03  Matteo Frigo  <athena@fftw.org>

	* gensrc/complex.ml, gensrc/complex.mli, gensrc/genfft.ml,
	gensrc/symmetry.ml, gensrc/variable.ml: Implemented mp3mdct
	generation mode for generating the MDCT used in mp3.

2000-06-02  Matteo Frigo  <athena@fftw.org>

	* cilk/executor_cilk.cilk, cilk/fftw_cilk.cilkh,
	cilk/fftwnd_cilk.cilk, cilk/Makefile, cilk/test_cilk.cilk,
	cilk/time_cilk.cilk, fftw/malloc.c, fftw/planner.c, fftw/putils.c,
	fftw/rader.c, fftw/twiddle.c: Adapted (simplified) to the
	forthcoming Cilk-5.3

	* gensrc/exprdag.ml: Iterate optimization until convergence.
	Saves two fops in fhb_9.c

2000-05-29  fftw  <fftw@fftw.org>

	* acx_pthread.m4: The autoconf folks like the macro name to be
	quoted in AC_DEFUN.

2000-05-20  fftw  <fftw@fftw.org>

	* fftw/fftw.h.in: If the user includes <complex.h> before
	<fftw.h>, then use the new C99 complex type for fftw_complex.
	This way, all the arithmetic operators, etcetera, are available to
	the user.  The C99 complex type should be binary-compatible with
	FFTW's struct-based type.

	* gensrc/ast.ml: deleted unused file

2000-05-19  Steven G. Johnson  <stevenj@fftw.org>

	* acx_pthread.m4: synchronized with macro archive, and added in
	Sequent -Kthread support.

2000-04-05  Steven G. Johnson  <stevenj@fftw.org>

	* doc/fftw.texi: slight change for clarity

2000-03-31  Steven G. Johnson  <stevenj@fftw.org>

	* acx_pthread.m4: only have one @author line, in accordance with
	needs of the autoconf macro archive.

2000-03-24  fftw  <fftw@fftw.org>

	* acx_pthread.m4: check to see if threads work with no arguments
	before trying -kthread, to avoid compiler warnings on such
	systems.

2000-03-23  fftw  <fftw@fftw.org>

	* configure.in: output message change

2000-03-23  Steven G. Johnson  <stevenj@fftw.org>

	* acx_pthread.m4: minor change

	* acx_pthread.m4: try PTHREAD_LIBS and PTHREAD_CFLAGS environment
	variables first

	* acx_pthread.m4: Added FreeBSD LinuxThreads port (-llthread)
	support.  Thanks to Jonathan Wilkins for his time and the use of
	his machine.

2000-03-21  fftw  <fftw@fftw.org>

	* acx_pthread.m4: fixed AC_DEFINE for HAVE_PTHREAD

	* acx_pthread.m4: added acknowledgments

	* acx_pthread.m4: include description strings for AC_DEFINEs so
	that autoheader will work

	* acx_pthread.m4: check for pthread.h before checking for threads
	libraries

	* acx_pthread.m4: don't check for cc_r if threads weren't found

	* acx_pthread.m4: check for -kthread, then -lpthread, then
	-pthread

	* threads/fftw_threads_test.c: added missing newline to error
	message

	* doc/fftw.texi: documented --with-openmp and --with-sgimp

	* threads/fftw_threads.c: bug fix in compiler thread directive
	loop

2000-03-20  fftw  <fftw@fftw.org>

	* configure.in, fftw/config.h.in, threads/fftw_threads.c,
	threads/fftw_threads-int.h: added experimental support for openmp
	and sgi mp compiler directives for threads code

	* Makefile.am: make sure acx_pthread.m4 is included in the dist

	* acx_pthread.m4: minor rewording in comment

	* acx_pthread.m4, configure.in, fftw/config.h.in,
	threads/fftw_threads.c: Separated POSIX threads library checks
	into a separate macro (ACX_PTHREAD) for submission to the autoconf
	macro repository (replacing an earlier macro there by Alejandro
	Cuervo).  Also, added checks for -pthread compiler flag required
	on FreeBSD (thanks to Jonathan Wilkins for the use of his machine
	for testing).

2000-03-02  Steven G. Johnson  <stevenj@fftw.org>

	* ChangeLog: fixed email addresses

	mpi/rfftw_mpi_test.c, mpi/rfftwnd_mpi.c, mpi/TOMS_transpose.h:
	whoops, kill acx_pthread test code

Wed Feb 23 17:07:23 2000  fftw  <fftw@fftw.org>

	* mpi/README.f77: noted column-major slab decomposition

Tue Feb 22 00:23:44 2000  Matteo Frigo  <athena@fftw.org>

	* doc/fftw.texi: Changed ``@iftex\\@tex\\@end tex\\@end iftex'' to
	``@tex\\@end tex'' because nesting is broken with texi2dvi-3.12
	and texi2dvi-4.00.  I don't know whether this is a texi2dvi bug or
	our fault.  (Nesting works properly if one does not use texi2dvi.)

Mon Feb 14 19:41:37 2000  Matteo Frigo  <athena@fftw.org>

	* gensrc/rconfig_prelude: Removed copyright, because it is added
	by makerconfig.sh.

Fri Feb 11 07:15:05 2000  fftw  <fftw@fftw.org>

	* FAQ/fftw-faq.bfnn: Noted problems with DEC CC.  Thanks to Xavier
	Marduel for the bug report.

Sun Feb  6 20:01:52 2000  fftw  <fftw@fftw.org>

	* gensrc/Makefile.fftw.am, gensrc/Makefile.rfftw.am,
	mpi/Makefile.am, threads/Makefile.am: Use $(srcdir)/foo instead of
	$<, since according to GNU Makefile conventions document, many
	non-GNU 'make' implementations only set $< for implicit rules.

Thu Jan 27 16:18:03 2000  fftw  <fftw@fftw.org>

	* configure.in, gensrc/Makefile.fftw.am, gensrc/Makefile.rfftw.am,
	mpi/Makefile.am, threads/Makefile.am: Used $@, $< in Makefile
	rules for srfftw.h, etcetera.  This should fix things in VPATH
	builds; thanks to Michael Poole for the suggestion.

Wed Nov 10 20:01:40 1999  Steven G. Johnson  <stevenj@fftw.org>

	* threads/fftw_threads-int.h: Yikes!  Self-#include should be
	fftw_threads.h.

Mon Nov  8 00:53:35 1999  Steven G. Johnson  <stevenj@fftw.org>

	* NEWS: noted (expected) 2.1.3 release date

	* doc/texi2html, AUTHORS: Updated Matteo's email address.

	* README: Noted mailing list URL.

Sun Nov  7 19:15:52 1999  Steven G. Johnson  <stevenj@fftw.org>

	* doc/fftw.texi: Reference latest version of gcc bug report.

	* acinclude.m4: Updated stack alignment check to also check for
	misaligned main() (due to OS/libc/loader problems), and to
	reference latest version of gcc bug report.

Fri Nov  5 01:49:21 1999  Steven G. Johnson  <stevenj@fftw.org>

	* NEWS: Thanked Diab Jerius for CFLAGS patch.

	* NEWS: noted that configure no longer overrides CFLAGS.

	* acinclude.m4: Fixed code so that configure will not override the
	CFLAGS environment variable.

Tue Nov  2 23:52:02 1999  Steven G. Johnson  <stevenj@fftw.org>

	* rfftw/rfftwnd.c, doc/fftw.texi: Ugh, ugh, triple ugh!  Had to
	modify the rule for stride interpretation of in-place rfftwnd
	transforms to handle a pathological case.  Before, if you did
	howmany transforms of size 1 (stride=1, dist=1) both the r2c and
	c2r transforms would work okay, BUT: the input of the r2c
	transform would have the required "padding" elements to make room
	for the complex output, while the c2r transform would output real
	numbers *without* padding (because of the idist==1 -> odist_t=1
	rule).  Thus, we'd have the bizarre situation of r2c + c2r = input
	in different order (no padding).  This caused the rfftwnd_mpi
	tests to fail for Nx1 transforms (N > 2).  So, I've modified the
	rule slightly to idist==1 && idist < istride.  This should
	continue to make rfftwnd do what we want in all the ordinary
	cases, but fixes this case.

Mon Nov  1 22:31:14 1999  Steven G. Johnson  <stevenj@fftw.org>

	* NEWS: noted that gcc stack alignment bug was only on x86.

Sun Oct 31 23:17:12 1999  Steven G. Johnson  <stevenj@fftw.org>

	* mpi/test_transpose_mpi.c: got rid of unused variables.

	* mpi/test_sched.c: got rid of unused variable

	* mpi/rfftw_f77_mpi.c: fixed typo

	* configure.in: awk -F can't be followed by a space in older
	awk's.

	* mpi/Makefile.am: added README.f77 to distribution

	* mpi/README.f77: minor fixes

	* fortran/fftw_f77.i: changed "c" comments to "!" to accommodate
	f90 freeform mode.  Also added params for experimental MPI
	wrappers.

Fri Oct 29 21:41:59 1999  Steven G. Johnson  <stevenj@fftw.org>

	* mpi/README.f77, mpi/fftw_f77_mpi.h: minor additions to
	documentation

	* Makefile.am: disable autoheader here too (it was a problem once
	today; why not before?)

	* mpi/README.f77, NEWS: Added description of experimental MPI
	wrappers.

	* acinclude.m4, configure.in: Use AC_F77_LIBRARY_LDFLAGS when
	attempting to link Fortran with C code in ACX_F77_FUNC_MANGLE.

	* fftw/config.h.in, mpi/Makefile.am, mpi/fftw_f77_mpi.c,
	mpi/fftw_f77_mpi.h, mpi/rfftw_f77_mpi.c, configure.in: Added
	experimental Fortran-callable wrappers for the MPI transforms.

	* acinclude.m4: small fix

Thu Oct 28 19:53:33 1999  Steven G. Johnson  <stevenj@fftw.org>

	* doc/fftw.texi: Noted stack alignment bug in gcc 2.95.[012].

	* NEWS, acinclude.m4, configure.in: Work around buggy stack
	alignment in gcc-2.95.x.

	* acinclude.m4, configure.in: Reorganized macros in acinclude.m4
	somewhat.  New checks for -fstrict-aliasing and try to guess cpu
	type on powerpc by looking at /proc/cpuinfo (using -mcpu=750 makes
	a ~10% difference on a PowerPC G3).

Tue Oct 26 21:45:06 1999  Steven G. Johnson  <stevenj@fftw.org>

	* tests/test_main.c: Added obligatory new joke for 2.1.3 release.

	* threads/executor_threads.c, threads/rexec_threads.c,
	rfftw/rexec.c, rfftw/rexec2.c, gensrc/to_c.ml, fftw/executor.c,
	fftw/fftw-int.h: Technically, macros with empty argument lists
	invoke undefined behavior in ANSI C, although they will be allowed
	in the C99 language revision.  Fix HACK_ALIGN_STACK_* macros to
	remove this usage.

	* fftw/config.h.in, fftw/fftw-int.h, doc/fftw.texi, configure.in:
	--enable-i386-hacks is no longer needed in gcc-2.95+
	(i.e. versions which have the -mpreferred-stack-boundary flag).

	* fftw/fftw-int.h: Indented alignment #preprocessor statements to
	make them more readable.  Also, made it so that you can use
	--debug-alignment even without --enable-i386-hacks.

Tue Oct 26 16:17:51 1999  Matteo Frigo  <athena@fftw.org>

	* ChangeLog: Updated ChangeLog

Tue Oct 26 05:47:25 1999  Steven G. Johnson  <stevenj@fftw.org>

	* acinclude.m4: No point in doing both -mcpu and -mtune (-mcpu
	includes -mtune).

	* doc/fftw.texi: Some fixes in Fortran docs.

	* rfftw/rexec.c, rfftw/rplanner.c, fftw/config.h.in,
	fftw/executor.c, fftw/planner.c, configure.in: Vector recursion is
	now enabled by a --enable-vec-recurse flag (disabled by default).

	* NEWS: Added version number.

Tue Sep 28 09:13:39 1999  Steven G. Johnson  <stevenj@fftw.org>

	* rfftw/rplanner.c, fftw/planner.c: Disable vector recursion for
	now.

	* fftw/rader.c, fftw/twiddle.c, fftw/config.h.in, fftw/fftw-int.h,
	FAQ/fftw-faq.bfnn, NEWS, configure.in: Fixed overflow for (x*y)%p
	in Rader routines (for complex transforms of prime sizes).  Thanks
	to Ezio Riva (ERiva@artis-software.com) for the bug report.

Thu Aug 19 03:08:29 1999  Steven G. Johnson  <stevenj@fftw.org>

	* NEWS: Noted Matlab wrapper bug fix.

Tue Aug 17 18:46:54 1999  Steven G. Johnson  <stevenj@fftw.org>

	* matlab/fftw.c: Fixed bug (memory leak; a new plan is created on
	each call for the multi-dim.  transforms).  Thanks to Matthew
	Davis <m.davis2@physics.ox.ac.uk> for the bug report.

Wed Jul 28 19:12:15 1999  Steven G. Johnson  <stevenj@fftw.org>

	* NEWS, configure.in: Fixed configure script problems with
	--enable-threads on Digital Unix.

Tue Jul 27 20:03:22 1999  Steven G. Johnson  <stevenj@fftw.org>

	* fftw.spec.in: Many changes, including several based on
	suggestions by Keith Amidon <camalot@picnicpark.org>.  Now install
	into the "build root" at build time so that building the RPM does
	not affect existing FFTW installations (and doesn't require root
	privileges).  Compilation (and configuration) now only occurs
	during the build phase.  Post install and uninstall scripts run
	ldconfig to update the linker database, and warn the user if the
	install directory is not in /etc/ld.so.conf.  Finally, the
	double-precision libraries are installed into the standard [r]fftw
	names instead of under d[r]fftw.

	* tests/test_main.c: Minor cleanup.

Sat Jul 24 20:32:58 1999  Steven G. Johnson  <stevenj@fftw.org>

	* tests/test_main.c, tests/test_main.h: Added -1
	(--only-one-speed-test) option, as I'm tired of waiting for the 8
	different speed tests to run when I only want one.

	* threads/fftw_threads_test.c, threads/rfftw_threads_test.c,
	tests/fftw_test.c, tests/rfftw_test.c, tests/test_main.c,
	tests/test_main.h, rfftw/rplanner.c, mpi/fftw_mpi_test.c,
	mpi/rfftw_mpi_test.c, fftw/fftw-int.h, fftw/fftw.h.in,
	fftw/fftwnd.c, fftw/planner.c, fftw/putils.c, fftw/rader.c,
	fftw/wisdom.c, fftw/wisdomio.c: Implemented new
	FFTW_NO_VECTOR_RECURSE flag to inhibit use of vector recursion.
	This flag is used internally in the planner to prevent vector
	recursion at anything other than the top level of the plan
	(instead of the planner_depth stuff used previously), and insures
	that the correct wisdom is used.  (Note, however, that the wisdom
	is still not specific to the vector_size parameter; this needs to
	be fixed.)

Mon Jul 19 17:04:16 1999  Steven G. Johnson  <stevenj@fftw.org>

	* fftw/fftw-int.h: Added a comment about why we have macros for
	trig. functions.

Mon Jun 21 16:01:44 1999  fftw  <fftw@fftw.org>

	* FAQ/fftw-faq.bfnn: Noted that SGI MipsPro bugs seem to have been
	fixed.  Also mentioned problems with egcs-1.0.2 on the PowerPC.

Sat Jun 19 17:47:28 1999  fftw  <fftw@fftw.org>

	* FAQ/fftw-faq.bfnn: Noted incorrect code generation in Metrowerks
	CodeWarrior Pro 4 for the Macintosh.  (Maybe we should rename this
	FAQ question?)

Fri Jun 18 19:20:28 1999  fftw  <fftw@fftw.org>

	* FAQ/m-html.pl: Updated FFTW Manual bookmark.

Sat Jun 12 05:03:31 1999  fftw  <fftw@fftw.org>

	* doc/fftw.texi: Added clarifications to fftwnd reference, as
	suggested by John F. Gibson of Cornell.

Tue Jun  8 22:17:35 1999  fftw  <fftw@fftw.org>

	* threads/fftw_threads-int.h, tests/test_main.c, matlab/fftw.m,
	gensrc/README, matlab/README, fftw/fftw-int.h, doc/fftw.texi,
	FAQ/html.refs, FAQ/m-html.pl, cilk/README, FAQ/fftw-faq.bfnn,
	TODO, fftw.spec.in, Makefile.am, README: Great URL change: web
	page -> www.fftw.org, ftp -> ftp.fftw.org, email -> @fftw.org.
	Note that currently, this means that some of links in the
	documentation are broken (links to sub-pages within the main FFTW
	site).  This will be fixed once we get real hosting for fftw.org.

Mon Jun  7 23:36:19 1999  fftw  <fftw@fftw.org>

	* fftw/config.h.in, fftw/fftw-int.h: Added warnings to flaky MacOS
	nanosecond timer routines.  (The ordinary Mac timer routines, with
	microsecond accuracy (in theory) are okay.)

Tue Jun  1 21:52:50 1999  fftw  <fftw@fftw.org>

	* fftw/fftw-int.h: Oops, I declared fftw_time twice.

	* fftw/fftw-int.h: Incorporated new timer code by Sampo Niskanen.

Mon May 31 17:45:34 1999  Matteo Frigo  <athena@fftw.org>

	* acinclude.m4: Added -arch host to osf-alpha CFLAGS.

Sat May 29 20:38:03 1999  fftw  <fftw@fftw.org>

	* Makefile.am: slight reformatting.

	* Makefile.am: Make sure lynx doesn't attempt to reformat logo gif
	data.

	* NEWS: Noted the date of each release (plus or minus a day or
	two, in some cases).  Merged release notes for beta releases with
	those of final releases.

Sat May 29 04:28:29 1999  Steven G. Johnson  <stevenj@fftw.org>

	* ChangeLog: ChangeLog now reflects all revisions of FFTW (instead
	of starting at 6/11/98).

	* ChangeLog: Updated change log.

Sat May 29 03:25:59 1999  fftw  <fftw@fftw.org>

	* doc/fftw.texi: Fixed another typo.

	* doc/fftw.texi: Typo fix.

Fri May 28 19:33:41 1999  fftw  <fftw@fftw.org>

	* fftw.spec.in, Attic/fftw.spec, Makefile.am, configure.in: You
	can now build the RPM package by running 'make rpm' (as root)
	after 'make dist'.  fftw.spec is now kept in sync automatically
	with the version numbers in configure.in.

Thu May 27 05:48:57 1999  fftw  <fftw@fftw.org>

	* threads/rexec_threads.c, rfftw/rplanner.c,
	threads/executor_threads.c, rfftw/rexec2.c, rfftw/rfftw.h,
	rfftw/rexec.c, fftw/rader.c, fftw/wisdom.c, fftw/putils.c,
	fftw/planner.c, fftw/fftw.h.in, fftw/fftw-int.h, fftw/executor.c:
	Initial version of "vector recursion" in executor.  No vector
	codelets yet.  The threads code works, but does not do vector
	recursion.  No use of vector recursion for in-place howmany loops
	yet.

Wed May 26 18:06:47 1999  fftw  <fftw@fftw.org>

	* gensrc/complex.ml: In times_3_3 routine, got rid of infinite
	loop for multiplication by non-constants (was biting us during
	generation of twiddle codelets).

	* gensrc/number.ml, gensrc/magic.ml, gensrc/genfft.ml,
	gensrc/exprdag.ml, gensrc/complex.ml: Various cleanup

	* tests/test_main.c, fftw/config.h.in, fftw/fftw.h.in: Centralized
	tests for Windows (in config.h.in) and use HAVE_WIN32 elsewhere.

Tue May 25 23:59:14 1999  fftw  <fftw@fftw.org>

	* NEWS: Removed extra period.

	* doc/fftw.texi: Noted possibility of "d" or "s" prefix in the
	tutorial (as requested by many users).

	* FAQ/fftw-faq.bfnn, Attic/fftw.spec, NEWS, configure.in: Bumped
	version number to 2.1.3, documented AIX threads fix.

	* threads/fftw_threads-int.h, threads/fftw_threads.c,
	fftw/fftw-int.h, configure.in, fftw/config.h.in, acinclude.m4:
	Fixed threads bug on AIX: pthread_create on AIX spawns detached
	(non-joinable) threads by default.  Also fixed much autoconf
	lossage on AIX.  Thanks to Jim Lindsay (lindsay@mill.acns.nwu.edu)
	for the bug report and for the use of Northwestern's SP2.

	* fftw/timer.c: Only use BSDgettimeofday if gettimeofday is not
	available (causes problems on some AIX systems).

	* tests/rfftw_test.c, tests/fftw_test.c, rfftw/rplanner.c,
	fftw/planner.c, fftw/fftw-int.h: Put (r)fftw_plan_hook in
	fftw-int.h, with a typedef, and used Andrew Sterian's DL_IMPORT
	macro to succor the lost souls using VC++.

Fri May 21 17:58:30 1999  fftw  <fftw@fftw.org>

	* tests/test_main.c: Fixed typo in help string.

Tue May 18 23:39:07 1999  fftw  <fftw@fftw.org>

	* threads/rfftw_threads_test.c, tests/test_main.h,
	threads/fftw_threads_test.c, tests/test_main.c,
	tests/rfftw_test.c, tests/fftw_test.c, mpi/rfftw_mpi_test.c,
	mpi/fftw_mpi_test.c, FAQ/fftw-faq.bfnn, NEWS: Whoops, found the
	real source of the MPI bug that was supposedly fixed in 2.1.2.
	MPI_Init can modify argv (and does so, for processes other than
	the first), but we passed the original argv to getopt.  This is
	now fixed.  (This is a bug in the MPI test programs of 2.1.2 also,
	but as it's only in the test programs and doesn't seem to bite us
	on any known MPI implementation, it can wait until the next FFTW
	release.)  Sigh.

Mon May 17 23:09:31 1999  fftw  <fftw@fftw.org>

	* NEWS: Went into more detail regarding the generator changes.

Mon May 17 22:20:27 1999  Matteo Frigo  <athena@fftw.org>

	* gensrc/symmetry.ml, gensrc/genfft.ml, gensrc/fft.ml: Fixed
	modified DCT/DST generation (realeven2/realodd2) so that it works
	now.  The simplifier really sucks for this, at the moment.  Why?

Sun May 16 23:59:33 1999  fftw  <fftw@fftw.org>

	* gensrc/genfft.ml: Fixed real[even,odd]2 codelet node type
	output.

	* gensrc/variable.ml, gensrc/variable.mli, gensrc/symmetry.ml,
	gensrc/genfft.ml: Added generators realeven2 and realodd2 for the
	modified DCT and DST (i.e. transforms for real data that are
	even/odd about n=-1/2, not n=0).

	* gensrc/exprdag.ml: Memoized eval for speed reasons.

	* gensrc/util.ml, gensrc/exprdag.ml: Implemented better
	statistics.

	hard-coded DCT/DST routines of small sizes.

	* gensrc/variable.mli, gensrc/variable.ml, gensrc/symmetry.ml,
	gensrc/genfft.ml, gensrc/complex.mli, gensrc/complex.ml: Added
	realeven and realodd codelet generation options.  (They work.)

Mon May 10 02:48:14 1999  fftw  <fftw@fftw.org>

	* doc/fftw.texi: Noted how to force compiler choice via CC
	env. variable.  Also added "compiler" index entry.

Thu May  6 22:35:05 1999  fftw  <fftw@fftw.org>

	* tests/test_main.c: --help option no longer causes an exit with
	an error code.

	* tests/test_main.c, configure.in, fftw/config.h.in: Test programs
	now use GNU-ly correct long options if getopt_long is available.

	* FAQ/fftw-faq.bfnn, NEWS: MPICH bug fix is apparently not
	specific to Linux (it also fixed the same problem on some
	Ultrasparcs).

	* Attic/fftw.spec: Updated for 2.1.2.

	* mpi/fftw_mpi_test.c: --only-parallel argument hack should also
	only be accessed by process 0.

Wed May  5 23:02:12 1999  fftw  <fftw@fftw.org>

	* NEWS: Noted addition of omitted fftw_f77_threads_init function.

	* FAQ/fftw-faq.bfnn: Bug fix (dates need to have two digits for
	the day).

	* threads/rfftw_threads_test.c, threads/fftw_threads_test.c,
	tests/test_main.c, tests/test_main.h, tests/rfftw_test.c,
	tests/fftw_test.c, mpi/rfftw_mpi_test.c, mpi/test_transpose_mpi.c,
	FAQ/fftw-faq.bfnn, mpi/fftw_mpi_test.c, NEWS, configure.in: Fixed
	bug when running test programs under MPICH; prepared for 2.1.2
	release.

	omission).

Tue Apr  6 19:29:13 1999  Steven G. Johnson  <stevenj@fftw.org>

	* configure.in: Check for hcc in addition to mpicc (hcc is used by
	the LAM MPI implementation).

Wed Mar 31 00:54:20 1999  Steven G. Johnson  <stevenj@fftw.org>

	* NEWS, doc/fftw.texi, ChangeLog: Fixed credit for 2.1.1 bug fix
	(real credit goes to Ming-Chang Liu, according to Jeff
	Briedenbach, whose name was misspelled anyway).

Tue Mar 30 18:19:21 1999  Steven G. Johnson  <stevenj@fftw.org>

	* FAQ/fftw-faq.bfnn: Moderated language.

	* NEWS: This isn't LaTeX, Matteo; an en dash in a monospaced font
	is rendered the same as a hyphen (i.e. "-" not "--").

Mon Mar 29 19:23:24 1999  Matteo Frigo  <athena@fftw.org>

	* ChangeLog: Updated

	* NEWS: Minor change.

Sun Mar 28 20:24:30 1999  Matteo Frigo  <athena@fftw.org>

	check for real->complex and complex->real transforms

Sun Mar 28 00:11:47 1999  fftw  <fftw@fftw.org>

	* NEWS: Moderated language.  I do not want to claim that the bug
	occurs in `rare' circumstances.  A bug is a bug, period.

	* tests/fftw_test.c, rfftw/rplanner.c: Implemented paranoid check
	for in-place complex planners.  I still don't know how to check
	real->complex plans, though (apart from rewriting test_ergun for
	real->complex and complex->real)

Fri Mar 26 22:58:57 1999  Steven G. Johnson  <stevenj@fftw.org>

	* doc/fftw.texi, FAQ/fftw-faq.bfnn, NEWS: Updated documentation

	enter_paranoid_mode() to threads & MPI test programs.

	* fftw/planner.c: Slight modification for future safety (not
	necessary now).

	verification of every single plan.

Tue Mar 23 17:44:35 1999  Matteo Frigo  <athena@fftw.org>

	* fftw/generic.c: Array read out of bounds---fixed.  Thanks to

	* FAQ/fftw-faq.bfnn: Noted free-ness in "What is FFTW?"
	description.

Mon Mar  8 20:21:46 1999  Steven G. Johnson  <stevenj@fftw.org>

	* threads/fftw_threads.c: By default, don't even try to specify
	PTHREAD_SCOPE_SYSTEM, since it causes problems on @!#%$ IRIX 6.5
	(in which PTHREAD_SCOPE_SYSTEM is not supported, but
	pthread_attr_setscope doesn't return an error!!!).  Just use the
	default attributes (fftw_pthread_attributes_p == NULL).

	* threads/fftw_threads.c: Fixed typo in comment.

	* NEWS: Added 2.1 news.

Mon Mar  8 18:00:37 1999  fftw  <fftw@fftw.org>

	* tests/rfftw_test.c, tests/fftw_test.c: Fixed pow(8192, x) -->
	pow(8192.0, x) .  This failed on Digital unix, I don't know why.

	Matteo).

	* gensrc/Makefile.rfftw.am, mpi/Makefile.am, threads/Makefile.am,
	gensrc/Makefile.fftw.am: Got rid of hackery in header creation,
	since circular dependencies are gone.  Also added prefixed headers
	to CLEANFILES so they get deleted by 'make clean'.

	* configure.in: Used xyz for prefix1 instead of just x, to make
	future conflicts less likely.

Mon Feb 22 18:55:16 1999  Matteo Frigo  <athena@fftw.org>

	* configure.in: Fix for irix didn't work, let's try this

	* ChangeLog: Fixed typo

	* ChangeLog: Updated

	* configure.in: Accounted for irix thread lossage

	* tests/test_main.c: usage() must normally exit, otherwise the
	test programs tries to read argv[] out of bounds.

	* doc/Makefile.am: fftw.ps used compressed fonts

	* gensrc/Makefile.rfftw.am, gensrc/Makefile.fftw.am: rfftw.h
	didn't go into distribution.  Fixed

	* threads/Makefile.am, gensrc/Makefile.rfftw.am, mpi/Makefile.am,
	configure.in, gensrc/Makefile.fftw.am: Removed circular
	dependencies

	* configure.in: Fixed typo

Mon Feb 22 05:19:40 1999  Steven G. Johnson  <stevenj@fftw.org>

	floating-point precision for -v.

	* mpi/rfftw_mpi_test.c, threads/Makefile.am,
	gensrc/Makefile.rfftw.am, mpi/Makefile.am, mpi/fftw_mpi_test.c,
	gensrc/Makefile.fftw.am: Made sure header files are not deleted
	when no prefix is added.  (Also got rid of some extraneous
	newlines printed by mpi code.)

	* configure.in, NEWS: Renamed 2.1 -> 2.1-beta1.

	* doc/Makefile.am: make clean shouldn't remove rfftwnd.gif.

Sun Feb 21 20:33:51 1999  Steven G. Johnson  <stevenj@fftw.org>

	* NEWS: Feature set for 2.1 is now frozen (I think).

	* doc/fftw.texi: slight change

	* mpi/Makefile.am, threads/Makefile.am, gensrc/Makefile.fftw.am,
	gensrc/Makefile.rfftw.am: Whoops!  Don't include
	XXX_FFTW_PREFIX_XXX header files in CLEANFILES, because that will
	cause 'make clean' to delete irreplaceable files when no prefix is
	being used.

	gensrc/Makefile.rfftw.am: Fixed installed headers to use
	FFTW_PREFIX for their own header inclusions.

	* configure.in, doc/fftw.texi, NEWS: Documented
	--enable-type-prefix.

	* mpi/Makefile.am, tests/Makefile.am, threads/Makefile.am,
	gensrc/Makefile.fftw.am, gensrc/Makefile.rfftw.am, acinclude.m4,

Sun Feb 21 17:35:28 1999  fftw  <fftw@fftw.org>

	* tests/Makefile.am, configure.in, gensrc/Makefile.fftw.am,
	gensrc/Makefile.rfftw.am, acinclude.m4: (Preliminary) hack: allow
	user to change name of fftw library.

	* configure.in: Added rfftw_mpi.h to list of files to install for
	--enable-mpi.

Sat Feb 20 23:00:41 1999  Steven G. Johnson  <stevenj@fftw.org>

	* FAQ/fftw-faq.bfnn: The ascii and info (but not html) versions of
	the FAQ were chopping off the answer to the last question.  Rather
	than fix the bug, I just added a trailing comment like in the
	Linux FAQ, which seems to correct the problem.

	* FAQ/fftw-faq.bfnn: Minor fixes and updates for 2.1.

	* mpi/rfftw_mpi_test.c, mpi/fftw_mpi.h, mpi/fftw_mpi_test.c,
	mpi/fftw_mpi.c: Share plans between forward and backward fftw_mpi
	plans (and between other fftw_mpi plans of the same size).

	* tests/rfftw_test.c, tests/fftw_test.c: In -p test with rank > 1,
	reduce the size of the arrays for the plan.

	* mpi/transpose_mpi.c: Got rid of compiler warning (code was okay,
	though).

	* doc/fftw.texi: small fix.

Sat Feb 20 03:27:36 1999  fftw  <fftw@fftw.org>

	"manually" add better version of gif figure.

	* doc/fftw.texi: Added link.

	* doc/Makefile.am: Make sure to distribute rfftwnd.fig.

	* doc/fftw.texi: Some post-reorganization grooming.

	* configure.in: Whoops!  Use $enableval, not $withval, in
	AC_ARG_ENABLE.

Fri Feb 19 23:50:45 1999  Matteo Frigo  <athena@fftw.org>

	* doc/Makefile.am, doc/fftw.texi: Added picture to postscript
	manual

Fri Feb 19 23:29:07 1999  fftw  <fftw@fftw.org>

	* configure.in: Added fort77 to list of fortran compiler (linux
	f2c comes with a program with this name)

	* doc/rfftwnd.gif, doc/rfftwnd.fig, doc/Makefile.am:
	Reverse-engineered rfftwnd picture from postscirpt to fig, so I
	can edit it and produce smaller postscript. (Linux rules!)

	* doc/fftw.texi: Restructured manual

Fri Feb 19 20:32:13 1999  Steven G. Johnson  <stevenj@fftw.org>

	* fftw/config.h.in, threads/fftw_threads-int.h, configure.in,

	main manual.

	* mpi/transpose_mpi.c: bug fix: when a process didn't have any
	local data, we weren't able to distinguish between in-place and
	out-of-place transposes, and were also incorrectly thinking that
	all block sizes were equal.

Sun Feb 14 20:21:50 1999  Steven G. Johnson  <stevenj@fftw.org>

	* tests/test_main.h, tests/test_main.c,
	mpi/Attic/test_fftwnd_mpi.c, mpi/Attic/time_fftwnd_mpi.c,
	mpi/fftw_mpi_test.c, configure.in, mpi/Makefile.am: Use standard
	fftw test program template for MPI tests.

	mpi/fftwnd_mpi.c, mpi/fftw_mpi.h: Added option of doing
	out-of-place transpose, so that we can take advantage of
	MPI_Alltoall primitive if the user provides enough space.

	* threads/fftw_threads.c: Don't require system to support
	PTHREAD_SCOPE_SYSTEM (although we prefer this over
	PTHREAD_SCOPE_PROCESS).

	wrapper files in sources.

	* mpi/transpose_mpi.c, mpi/Attic/time_fftwnd_mpi.c,

	mpi/TOMS_transpose.h, mpi/fftwnd_mpi.c, mpi/Attic/Makefile:
	Updated MPI routines.  The new implementation is almost completely
	rewritten from before, and should (hopefully) be easier to manage
	and (maybe) faster in some cases.

	* configure.in: Check for pthread_create outside of -lpthread,
	since some systems may have threads built into the standard C
	libraries.

	* fftw/malloc.c: Allow allocation/freeing of 0-size blocks/NULL
	pointers (since that is ANSI-okay, after all).

	* cilk/executor_cilk.cilk: Use ntwiddle instead of r-1 in case
	twiddle policy changes.

	* mpi/Attic/time_fftwnd_mpi.c: Whoops!  don't pass uninitialized
	out parameter (shouldn't be a problem in any case since transform
	is in-place, but better safe than sorry).

Thu Feb 11 02:31:45 1999  Steven G. Johnson  <stevenj@fftw.org>

	* doc/fftw.texi: Noted necessity of linking threads-using code
	with -lpthread or whatever.

	fftw/f77_func.h, fftw/fftwf77.c, fftw/config.h.in, configure.in,
	doc/fftw.texi, NEWS, acinclude.m4: Fortran wrapper functions are
	now automatically included in the main FFTW libraries, unless the
	--without-fortran option is passed to configure.  They are also
	documented in the main manual.

	* doc/fftw.texi: Fixed broken cross-reference.

Wed Feb 10 22:47:01 1999  Steven G. Johnson  <stevenj@fftw.org>

	* threads/Attic/README, doc/fftw.texi, NEWS: Documented threads
	routines in the main FFTW manual.

	* threads/fftw_threads.c: Make sure spawn_loop handles nthreads ==
	0.

	* threads/fftw_threads-int.h, threads/rfftwnd_threads.c,
	threads/executor_threads.c: Set things up so that we could pass
	workspace to fftw_many_inplace_threads.

	* threads/fftw_threads.c: Improved load-balancing of threads
	slightly, although in practice it doesn't seem to make much
	difference.

	* threads/rfftwnd_threads.c, threads/rexec_threads.c,
	threads/rfftw_threads.h, threads/rfftw_threads_test.c: For greater
	consistency, make sure "threads" suffix always directly follows
	rfftw or rfftwnd.

	* threads/rfftwnd_threads.c, threads/rexec2_threads.c,
	threads/rexec_threads.c, threads/rfftw_threads.h,
	threads/fftw_threads-int.h, threads/fftw_threads.c,
	threads/fftwnd_threads.c, threads/executor_threads.c: Cleaned up
	loop-parallelizing interface considerably.

	threads/rexec_threads.c, threads/executor_threads.c,
	threads/fftw_threads-int.h, threads/fftw_threads.h, configure.in,
	threads/Makefile.am, NEWS: Added first stab at parallel (threads)
	rfftw.

	* rfftw/rfftwnd.c, rfftw/rexec.c: Slight stride/dist fix (to make
	behavior in in-place transforms more in line with what the manual
	says),

Fri Feb  5 22:53:13 1999  Steven G. Johnson  <stevenj@fftw.org>

	* tests/test_main.c: Noted -x and -f options in -h help.

	* threads/executor_threads.c: Yikes!  Use ntwiddle instead of r-1
	in twiddle_thread.  (This would have been a problem if we ever
	changed the twiddle policy.)

	* threads/fftwnd_threads.c, threads/executor_threads.c,
	threads/fftw_threads-int.h, fftw/config.h.in: Use autoconf to
	determine if alloca is available and use malloc/free if it is not.

	* NEWS: Noted improvements to <n> argument for test programs.

	* tests/fftw_test.c: Removed unnecessary testing of both real and
	imaginary impulses--this is unnecessary since we check linearity
	under multiplication by complex scalars.

	* tests/test_main.c: (Whoops!)  Turn interactive mode back off
	when getopt is available.

	* tests/test_main.c: Added support for new <n> format to

	automatically by configure when it is available.

Mon Oct 19 15:56:50 1998  Matteo Frigo  <athena@fftw.org>

	* tests/test_main.c: Replaced 2x2 linear system with fib() in
	timer iteration.  The linear system was converging to 0 in

	* configure.in: Fixed usage of ` in echo.

Tue Oct  6 04:46:04 1998  Steven G. Johnson  <stevenj@fftw.org>

	* gensrc/genfft.ml: Changed <athfft.h> -> "athfft.h"

	each new version.

	* README.hacks: Postponed computation of the phase of the moon
	until FFTW 17.0.

	* doc/fftw.texi: Explained "out of place" in tutorial.

	* doc/fftw.texi: Added a couple of clarifications to the
	installation on non-Unix section.

	* NEWS: Fixed typo.

	transforms.

	* tests/test_main.c: Added -b flag for testing really large
	transforms.

	* fftw/fftwnd.c: Initialize nwork to zero (not really necessary,
	but it doesn't hurt to make sure things are initialized).

	* rfftw/rfftwnd.c: Fixed another parenthesization problem which
	caused overflow problems with rank > 2 transforms.

Sat Sep 26 19:57:25 1998  Steven G. Johnson  <stevenj@fftw.org>

	* rfftw/rfftwnd.c: Yeow!  Integer precision overflow occurs for
	final dim. >= 2^16 due to inauspicious parenthesization.  Fixed.

Fri Sep 25 21:55:28 1998  Steven G. Johnson  <stevenj@fftw.org>

	installation for non-unix section.

Fri Sep 18 16:36:20 1998  Steven G. Johnson  <stevenj@fftw.org>

	* fftw/fftwnd.c: Modified buffered transforms to use a skew
	(padding) between buffers, and also to do contigous writes instead
	of reads when copying result from buffers back to array.  Thanks
	to Geert van Kempen for the tips.

	* fftw/fftw.h.in: Added Andrew Sterian's patch to allow FFTW to be
	used as a shared library more easily on Win32.

	now should work across all generations of gcc/egcs, whether
	building a shared library or not.

	* doc/fftw.texi: Noted use of fast algorithm for prime sizes in
	complex transforms.  Got rid of <MATH> tag everywhere (doesn't

	* doc/fftw.texi: Various fixes and modifications.

	* doc/fftw.texi: Added rfftwnd quick start.

	* doc/fftw.texi: public-domain -> freely-available (FFTW, along

	* doc/fftw.texi: Minor additions.

	* doc/fftw.texi: Wrote rfftw quick start.

	* fftw/twiddle.c, fftw/rader.c: Use FFTW_FORWARD instead of a

Wed Aug 19 23:55:39 1998  fftw  <fftw@fftw.org>

	* doc/fftw.texi: Changed reference in the introduction--an

	anything about DFTs.  Also some minor changes.  Alluded to a
	License and Copyright section.

	* gensrc/symmetry.ml, gensrc/magic.ml, gensrc/fft.ml,
	gensrc/exprdag.mli, gensrc/exprdag.ml, gensrc/expr.mli,
	gensrc/expr.ml: Implemented three-phase simplifier.

	* gensrc/symmetry.ml, gensrc/magic.ml, gensrc/fft.ml: Reset

	properly.

	* gensrc/number.ml, gensrc/magic.ml, gensrc/genfft.ml,
	gensrc/fft.ml, gensrc/exprdag.mli, gensrc/exprdag.ml,
	gensrc/Makefile.sources, gensrc/Makefile.genfft: Disabled new
	convolution hack for n >= 17, since the naive algorithm is better.
	The hack is similar to Rader's variant 4 in Tolimieri's book, and
	the growth of the operation count is also documented in that book.

	* TODO: Updated to reflect the fact that we have now rewritten
	rfftw.

	* fortran/Attic/README: Fixed erroneous listing of rfftwnd.

	fortran/Attic/README: Added rfftw wrappers.

Tue Aug 18 23:52:19 1998  fftw  <fftw@fftw.org>

	* gensrc/exprdag.ml, gensrc/expr.ml, gensrc/Makefile.genfft:
	Another horrible hack in the generator speeds up n=13 by a lot.

	* rfftw/Attic/rfftwint.h: Whoops!  Deleted extraneous characters.

	* rfftw/rplanner.c, rfftw/rgeneric.c, rfftw/rfftwnd.c,
	rfftw/Attic/rfftwint.h, rfftw/rfftw.h, rfftw/rexec2.c,
	rfftw/rexec.c, gensrc/Makefile.rfftw.am: Added invoke_many routine
	for rfftw, and split hacks into separate header file (rfftwint.h).

	* gensrc/magic.ml, gensrc/genfft.ml, gensrc/fft.ml,
	gensrc/exprdag.ml, gensrc/Makefile.sources: Implemented new way of
	doing Rader's algorithm.

	* NEWS: Noted fftw_one, etcetera.

	* ChangeLog: Line-wrapped entries.

	* tests/rfftw_test.c, rfftw/rfftwnd.c: Yikes!  Bug fix.  In the
	future, be sure to try running the test program with the -m
	option, since the rfftwnd specific planner operates signficantly
	differently under FFTW_MEASURE than under FFTW_ESTIMATE.

Mon Aug 17 23:27:23 1998  fftw  <fftw@fftw.org>

	* tests/test_main.c: Also sprach g++: the `gets' function is
	dangerous and should not be used.

	* rfftw/rfftwnd.c, fftw/rader.c, fftw/malloc.c: Made g++ happy

	* rfftw/rplanner.c, fftw/putils.c, ChangeLog: Fixed wrong

	fftw/fftwnd.c, fftw/fftw.h.in, fftw/fftw-int.h: Added
	FFTW_THREADSAFE flag, which is intended to guarantee that the plan
	be read-only, making it safe to use the same plan in parallel from
	multiple threads.  Currently, it only has an effect in the
	multi-dimensional transforms (the 1d plans are already read-only).

	* tests/Makefile.am, rfftw/rfftw.h, rfftw/rexec2.c, rfftw/rexec.c,
	fftw/executor.c: Optimized the aligned _many loop.  Fixed
	alignments in rexec2.c

	* rfftw/rexec.c, fftw/fftw-int.h, fftw/executor.c: Reorganized
	alignment hacks to be more robust with different compilers and
	compiler flags.

	* tests/Makefile.am: automake TESTS variable expects the names of
	actual executables, not simple 'make' dependencies.  Fixed by
	overriding 'make check' behavior instead of using TESTS.

	* tests/test_main.c, tests/Makefile.am: Added 'make check'
	feature, along with flag to test programs to limit the number of
	iterations.

	* tests/test_main.h, tests/test_main.c, tests/rfftw_test.c,
	tests/fftw_test.c, rfftw/rfftwnd.c, rfftw/rfftw.h, rfftw/rexec.c,
	fftw/fftwnd.c, fftw/fftw.h.in, fftw/executor.c: Added fftw_one and
	friends, and modified the test programs to check them.

	* doc/fftw.texi: Capitalization changes, clarifications, and other
	minor changes.

	* doc/texi2html, doc/fftw.texi: Restructured manual (still
	incomplete)

	rfftw/rexec.c, fftw/twiddle.c, fftw/timer.c, fftw/rader.c,
	fftw/putils.c, fftw/planner.c, fftw/malloc.c, fftw/generic.c,
	fftw/fftwnd.c, fftw/fftw-int.h, fftw/executor.c, fftw/config.h.in:
	Many cosmetic changes.  ``optimized'' rexecutor slightly.

	* fftw/rader.c: Calls fftw_executor_simple directly instead of
	calling fftw().

	* tests/test_main.h, tests/test_main.c, tests/rfftw_test.c: Fixed
	(hopefully) a problem with roundoff errors sometimes exceeding the
	tolerance.

Sun Aug 16 22:55:43 1998  fftw  <fftw@fftw.org>

	* rfftw/rgeneric.c: ``optimized'' rgeneric codelets (kind of)

	* fftw/fftw-int.h, fftw/config.h.in, configure.in: Added separate
	--enable-debug-alignment flags for debugging x86 alignments (the
	--enable-debug flag also changes the compiler flags, which we
	don't want to do).

	* rfftw/rplanner.c, fftw/putils.c: Bug fix--make sure to only call
	rgeneric codelets for odd n.

	* rfftw/rexec2.c, gensrc/Makefile.sources: Fixed x86 alignments.

	* tests/test_main.c: -s now interacts with -d 1 in the same way
	that -c and -a do.

	* NEWS: Slight clarification.

	* rfftw/rplanner.c: Planner can now decide on the best place to
	use generic codelets.

	* fftw/planner.c: Planner now decides the best place to put
	generic/Rader codelets.

	* fftw/putils.c: Changed message for Rader print_plan.

	* tests/rfftw_test.c, fftw/rader.c, fftw/putils.c, fftw/fftw.h.in:
	Modified Rader to use only a single plan for forward and backward
	transforms of the convolution.

Sat Aug 15 22:35:05 1998  fftw  <fftw@fftw.org>

	* NEWS: Noted the news.

	* threads/Attic/Makefile, tests/Makefile.am, mpi/Attic/Makefile,
	matlab/Makefile, gensrc/config, gensrc/README, fftw/fftw-int.h,
	doc/fftw.texi, cilk/README, cilk/Makefile, FAQ/fftw-faq.bfnn,
	configure.in, README.hacks, Makefile.am, INSTALL: The great
	directory renaming: src -> fftw.

	* fftw/twiddle.c, fftw/rader.c, fftw/putils.c, fftw/fftw.h.in,
	fftw/fftw-int.h, fftw/executor.c: Added sharing of Rader data and
	twiddles between different plans (and within the same plan).

	* tests/test_main.c, fftw/malloc.c, fftw/fftw.h.in: When debugging
	is enabled, keep track of the peak memory usage (and report it in
	the test programs).

	* fftw/rader.c: Rader is now prepared to share data between
	forward and backward transforms.

	* fftw/rader.c, fftw/fftw.h.in, fftw/fftw-int.h, fftw/executor.c:
	Whoops, forgot to add rader.c to the repository.  Also got rid of
	an unused variable and include prototypes for the *_ops functions
	in fftw-int.h.

	* fftw/twiddle.c, fftw/putils.c, fftw/planner.c, fftw/fftw.h.in,
	fftw/fftw-int.h, fftw/executor.c, gensrc/Attic/Makefile.am: Added
	Rader codelets to handle large prime factors.

	* fftw/putils.c, fftw/planner.c, fftw/fftw.h.in, fftw/fftw-int.h,
	rfftw/rplanner.c, rfftw/rgeneric.c, rfftw/rexec.c,
	gensrc/Makefile.rfftw.am: Implemented generic codelet. (inverse
	does not work yet)

	* fftw/putils.c, fftw/generic.c, fftw/fftw.h.in, fftw/fftw-int.h,
	rfftw/rplanner.c, rfftw/rfftw.h, rfftw/rexec2.c, rfftw/rexec.c:
	Split NOTW from HC2REAL and TWIDDLE from HC2HC, to avoid horrible
	type confusion and let me modify the various codelts type
	separately

	* tests/rfftw_test.c: Fixed bug in in-place testnd.  (It's working
	now...hooray!)

	* tests/test_main.h: CHECK now calls fftw_die instead of exit
	(mainly to make it easier to breakpoint).

	* fftw/wisdom.c, fftw/twiddle.c, fftw/timer.c, fftw/putils.c,
	fftw/planner.c, fftw/malloc.c, fftw/generic.c, fftw/fftwnd.c,
	fftw/fftw.h.in, fftw/fftw-int.h, fftw/config.h.in,
	fftw/.indent.pro, rfftw/rplanner.c, rfftw/rfftwnd.c,
	rfftw/rfftw.h, rfftw/.indent.pro, gensrc/.indent.pro: Moved code
	around to avoid unnecessary linking dependencies.

	* tests/rfftw_test.c, fftw/putils.c, fftw/planner.c,
	fftw/generic.c, fftw/fftw-int.h, fftw/.indent.pro,
	rfftw/rplanner.c, rfftw/rfftwnd.c, rfftw/rfftw.h, rfftw/rexec2.c,
	rfftw/rexec.c, rfftw/.indent.pro, gensrc/Attic/Makefile.am,
	gensrc/.indent.pro: Splitted planner.c into two files, so that the
	liker does not load the complex codelets if only rfftw is used.
	Renamed rfftw_plan->fftw_plan, since they are the same and we do
	not seem able to maintain consistency internally.

	* ChangeLog: Updated changelog

	* fftw/executor.c, rfftw/rexec2.c: Removed redundant test

	* tests/rfftw_test.c, rfftw/rfftwnd.c: Fixed more bugs in in-place

	* tests/test_main.c: test -d 1 -a now uses nd routines, consistent
	with -d 1 -c <n>.

	* fftw/malloc.c: Need to flush(stdout) before printing to stderr,
	or messages sometimes come in the wrong order.  Also, should pass
	EXIT_FAILURE instead of 1 to exit().

	* fftw/executor.c, rfftw/rexec.c: Fixed those damned alignments.

	* tests/test_main.h, tests/test_main.c, tests/rfftw_test.c,
	tests/fftw_test.c: Multi-dimensional tests are getting closer to
	working...

	* rfftw/rfftwnd.c, rfftw/rexec2.c: Bug fixes.

	* fftw/fftw-int.h, fftw/executor.c, rfftw/rexec.c, gensrc/to_c.ml,

	rfftw/rfftwnd.c, rfftw/rexec2.c, rfftw/rexec.c, rfftw/.indent.pro,
	configure.in: Added extra wisdom flag.  Renamed to V2.0.

	* tests/Makefile.am: Registered testmain.h with automake, so that
	it gets distributed

	* Makefile.am: Compile rfftw before tests (otherwise make fails)

	* tests/rfftw_test.c: Fixed in-place testing bug.

	codelets.

	INCOMPATIBLE CHANGE: hc2hc codelets are marked FFTW_HC2HC instead
	of FFTW_HC2HC_FORWARD and FFTW_HC2HC_BACKWARD.  The direction is
	given by the dir flag.

	* gensrc/schedule.ml: Added some comments

	* gensrc/schedule.ml, gensrc/dag.mli, gensrc/dag.ml: Changed
	scheduler to work properly with DIF codelets.

	gensrc/fft.ml, gensrc/.indent.pro: genfft now generates real2hc
	codelets

Sat Aug  8 18:38:05 1998  fftw  <fftw@fftw.org>

	* threads/fftwnd_threads.c, tests/fftw_test.c, fftw/wisdom.c,

	* threads/fftwnd_threads.c, tests/fftw_test.c, fftw/wisdom.c,
	fftw/twiddle.c, fftw/planner.c, fftw/malloc.c,
	rfftw/Attic/rfftw.c, gensrc/makeconfig.sh, gensrc/genfft.ml: (foo
	*) 0 -> NULL, since the former is technically non-portable (it
	assumes that a NULL pointer is equivalent to the cast of an
	integer 0).

Fri Aug  7 21:38:54 1998  fftw  <fftw@fftw.org>

	* ChangeLog: Updated changelog

	* configure.in: test $CC is incorrect if CC contains a space.

	* doc/fftw.texi: configure -> ./configure

Thu Aug  6 07:14:42 1998  fftw  <fftw@fftw.org>

	* fftw/wisdomio.c, fftw/Attic/common_io.c,

	meet 8.3 filename restriction.  (sigh)

Sun Aug  2 20:42:25 1998  fftw  <fftw@fftw.org>

	* fftw/fftw-int.h: Got rid of PASTE(x,FFTW_REAL_SUFFIX) since
	invoking macros with empty arguments (e.g. the default value of
	FFTW_REAL_SUFFIX) produces undefined behavior in ANSI C (the 1989
	ISO standard).  (The C9X standard will fix this.)

Fri Jul 31 19:57:42 1998  fftw  <fftw@fftw.org>

	* tests/fftw_test.c: main() now returns 0 instead of calling
	exit(0).

	"accuracy" when describing the output of fftw_test -t.

	* ChangeLog: Added ChangeLog entry.  You can update the ChangeLog
	in emacs with M-x vc-update-change-log.  Then you can remove
	trivial comments from the log manually.

	* threads/Attic/time_threads.c, threads/Attic/test_threads.c,
	threads/fftwnd_threads.c, threads/fftw_threads.h,

	fftw_complex, fftw_real.

	--enable-debug option; supercedes old MALLOC_DEBUG flag in
	malloc.c.

	* gensrc/Attic/Makefile.am: Fixed bug in makefile

	* tests/Makefile.am, rfftw/Attic/Makefile.am, configure.in,
	ChangeLog: Added libtool support

	* tests/Attic/Makefile.in, tests/Makefile.am,
	gensrc/makemakefile.sh, gensrc/install.sh,
	gensrc/Attic/Makefile.in, gensrc/Attic/Makefile.am,

	threads/executor_threads.c, tests/fftw_test.c, rfftw/rfftwnd.c,
	mpi/Attic/test_fftwnd_mpi.c: Replaced "illegal" with "invalid."

	* fftw/twiddle.c, fftw/generic.c: Replaced double with FFTW_REAL
	in twiddle generation (to make it easier to use long double, etc.)

Tue May  5 14:56:51 1998  fftw  <fftw@fftw.org>

	* fftw/twiddle.c, fftw/executor.c: Replaced illegal->invalid.  To
	hell with the laywers.

Fri Apr 17 19:44:12 1998  fftw  <fftw@fftw.org>

	* configure.in: Fixed HPUX case pattern.

	* configure.in: Added HP-UX CFLAGS.

	* fortran/Attic/fftw_f77.c: Added HP/UX case (no underscore, all

	default.

Wed Apr 15 16:01:03 1998  fftw  <fftw@fftw.org>

	* gensrc/number.ml: Added a few more digits to twopi constant.
	(Not that it matters, since we will have to modify the
	float_to_num function to get more than 9 digits of accuracy.

Tue Apr 14 20:38:49 1998  fftw  <fftw@fftw.org>

	* doc/fftw.texi: Added new DARPA grant #.  Renamed arpa->darpa.
	Maybe we should write a macro

	\def\arpa{\ifnum\phaseofmoon1\then DARPA\else ARPA\fi}

	* threads/Attic/time_threads.c: Eeep!  Fixed bug that didn't allow
	you to call time_threads without passing a rank parameter.

Fri Apr 10 23:14:54 1998  fftw  <fftw@fftw.org>

	* FAQ/fftw-faq.bfnn: Fixed missing \}.

	* FAQ/fftw-faq.bfnn: Small changes.  Fixed grammatical error.

	* doc/fftw.texi: Small changes.

	compiling in single precision.

	* FAQ/fftw-faq.bfnn: Added (abbreviated) Sun SC4.0 warning back
	into the FAQ.

	* fftw/timer.c: Removed cast (void *)0 in gettimezone.
	Technically, this should be (struct timezone *)0.  ANSI C++
	forbids conversion from void * to other pointers in function
	arguments.  Just 0 should be fine, since 0 is valid syntax for the
	null pointer of any type.

	of spurious warnings

	* tests/fftw_test.c: Wording change in joke.

	* tests/fftw_test.c: Reduced maximum size for random 1D tests.

	* tests/fftw_test.c: Some new jokes.  Removed redundant
	Windows-specific joke.  (Why beat a dead horse?)

	checking twiddle by n followed by no_twiddle of size 1 (unless
	there is no other plan yet).  (There is no way that this is going
	to be faster than no_twiddle of size n, for example.)
