* 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>

* 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>

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

* 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: 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

* 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

* 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).

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?)

* 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.

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>

improving.
* gensrc/symmetry.ml: Fixed comment.
* 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.
* gensrc/exprdag.ml: Improved complexity of network transposition
from O(n^2)=O(slow) to O(n) [times O(polylog)]

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.

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
for FFTW 2.1.1.

mpi/rfftw_mpi_test.c, mpi/fftw_mpi_test.c: Added definition of
enter_paranoid_mode() to threads & MPI test programs.

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) -->

* doc/fftw.texi: Added @cindex floating-point precision
* doc/fftw.texi: Updated index.
* doc/fftw.texi: typo fix: rfftwnd_threads_*_one ->
rfftwnd_threads_one_*
* doc/fftw.texi: Print table of contents at the end, as directed
by the texinfo manual, so that pagination is not screwed up when
the TOC has an odd number of pages.

* FAQ/fftw-faq.bfnn: Noted workaround for buggy SGI compilers.
* ChangeLog: Line-wrapped (I wish you would remember to do this,
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

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>

* 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.
* mpi/Makefile.am, threads/Makefile.am, gensrc/Makefile.fftw.am,
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,
configure.in: Use FFTW_PREFIX for all installed files.

* 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>
* doc/fftw.texi: Minor tweaks
Sat Feb 20 02:57:37 1999 Steven G. Johnson <stevenj@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,

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/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).
* gensrc/Makefile.fftw.am, gensrc/Makefile.rfftw.am: Include f77

mpi/Attic/fftwnd_mpi.h, mpi/sched.c, mpi/TOMS_transpose.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.

routines in the main FFTW manual.
* threads/fftw_threads.c: Make sure spawn_loop handles nthreads ==

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/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.
* threads/fftw_threads_test.c: Call fftw_threads_init when
starting up.
* threads/Attic/time_threads.c, threads/Attic/test_threads.c,
threads/fftwnd_threads.c, threads/fftw_threads.h,

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
interactive mode.
Fri Jan 29 00:09:00 1999 Matteo Frigo <athena@fftw.org>

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
floating point, and it caused underflow problems.
Wed Oct 7 16:15:39 1998 Steven G. Johnson <stevenj@fftw.org>
* configure.in: Fixed usage of ` in echo.
Tue Oct 6 04:46:04 1998 Steven G. Johnson <stevenj@fftw.org>
* configure.in: Got rid of message about enabling the x86 cycle
counter--why are we loudly suggesting a deprecated option?
Interested users can read the manual.

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

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
rader_min to 13, until I understand how to simplify the code
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.

rfftw.
* fortran/Attic/README: Fixed erroneous listing of rfftwnd.
* fortran/Attic/fortranize.h, fortran/Attic/README: Various
improvements.

Tue Aug 18 23:52:19 1998 fftw <fftw@fftw.org>
* gensrc/exprdag.ml, gensrc/expr.ml, gensrc/Makefile.genfft:

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
arguments in make_node_rgeneric. (Ouch!)
* tests/rfftw_test.c, tests/fftw_test.c, rfftw/rfftwnd.c,
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/rplanner.c, rfftw/rgeneric.c, rfftw/rfftw.h,
rfftw/rexec.c, fftw/twiddle.c, fftw/timer.c, fftw/rader.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.

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

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/.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

Tue Aug 11 22:40:02 1998 fftw <fftw@fftw.org>
* gensrc/variable.mli, gensrc/variable.ml, gensrc/makeconfig.sh,
gensrc/genfft.ml, gensrc/fft.ml: Added hc2real codelets
* gensrc/variable.ml, gensrc/fft.ml: Fixed a couple of bugs in the
generator
Mon Aug 10 22:57:14 1998 fftw <fftw@fftw.org>
* gensrc/variable.mli, gensrc/variable.ml, gensrc/to_c.mli,
gensrc/to_c.ml, gensrc/genfft.ml, gensrc/fft.ml,
gensrc/complex.mli, gensrc/complex.ml: Implemented hc2hc-forward
pass (not tested yet)
* gensrc/to_c.mli, gensrc/to_c.ml, gensrc/genfft.ml: renamed
confusing function `make_unparser'
* gensrc/variable.mli, gensrc/variable.ml, gensrc/genfft.ml,
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,
fftw/twiddle.c, fftw/planner.c, fftw/malloc.c,
rfftw/Attic/rfftw.c, gensrc/genfft.ml: Reverted NULL -> (foo *) 0
* 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 $CC is incorrect if CC contains a space.
Fixed to test "$CC"
* doc/fftw.texi: configure -> ./configure
Thu Aug 6 07:14:42 1998 fftw <fftw@fftw.org>
* fftw/wisdomio.c, fftw/Attic/common_io.c,
gensrc/Attic/Makefile.am: Changed common_io.c -> wisdomio.c to
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).
Tue Jul 28 23:04:55 1998 fftw <fftw@fftw.org>

control.
Thu Jun 11 23:24:31 1998 fftw <fftw@fftw.org>

decipher users' image and audio formats.
Wed May 6 16:44:13 1998 fftw <fftw@fftw.org>
* fftw/twiddle.c, fftw/fftw-int.h, gensrc/to_c.ml: Wrapped
constants in FFTW_KONST() and made a couple of other changes to
make it easier to use other floating point types.
* threads/Attic/time_threads.c, threads/Attic/test_threads.c,
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.)
Also removed spurious math.h inclusion from generic.c.
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.

* configure.in: Added HP-UX CFLAGS.
* fortran/Attic/fftw_f77.c: Added HP/UX case (no underscore, all
lower-case), and deleted Solaris case since it is the same as the
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.
Sat Apr 11 04:38:06 1998 fftw <fftw@fftw.org>

someone compiles FFTW with a mix of C and C++ compilers.
Fri Apr 10 23:14:54 1998 fftw <fftw@fftw.org>

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.

then copies tmp->in instead of the other way around...this gives a
speed gain for large multi-dim. transforms (I think...still need
to run the regular benchmark on various platforms).
