1999-05-17  fftw  <fftw@glauke.lcs.mit.edu>

        * NEWS: Noted codelet generator speed.

        * gensrc/symmetry.ml, gensrc/genfft.ml, gensrc/fft.ml: Improved
        real{even|odd}2 transforms

        * doc/fftw.texi: Fixed typo.

        * gensrc/exprdag.ml: Improved simplifier for DCT-type transforms.

        * TODO: Noted that the transpose routines for MPI could use
        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?

1999-05-16  fftw  <fftw@glauke.lcs.mit.edu>

        * 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)]

        * TODO: Noted that the generator can now output efficient
        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.)

1999-05-10  fftw  <fftw@glauke.lcs.mit.edu>

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

1999-05-07  fftw  <fftw@glauke.lcs.mit.edu>

        * TODO, NEWS: Updated TODO.

        * README: Fixed Cilk URL.

        * NEWS: Noted GNU-style long options in the test programs.

1999-05-06  fftw  <fftw@glauke.lcs.mit.edu>

        * 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).

        * fftw.spec: Updated for 2.1.2.

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

1999-05-05  fftw  <fftw@glauke.lcs.mit.edu>

        * 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.

        * tests/test_main.c: Added joke.

1999-04-10  fftw  <fftw@glauke.lcs.mit.edu>

        * FAQ/fftw-faq.bfnn: Added linker FAQ entry.

1999-04-07  stevenj  <stevenj@glauke.lcs.mit.edu>

        * threads/fftw_f77_threads.c: Added missing fftw_f77_threads_init
        function (thanks to V. Sundararajan for pointing out the
        omission).

1999-04-06  stevenj  <stevenj@glauke.lcs.mit.edu>

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

1999-03-31  stevenj  <stevenj@glauke.lcs.mit.edu>

        * 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).

1999-03-30  stevenj  <stevenj@glauke.lcs.mit.edu>

        * 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 "--").

1999-03-29  Matteo Frigo  <athena@supertech.lcs.mit.edu>

        * ChangeLog: Updated

        * NEWS: Minor change.

1999-03-28  Matteo Frigo  <athena@supertech.lcs.mit.edu>

        * tests/rfftw_test.c, tests/fftw_test.c:
        Implemented paranoid check for real->complex and complex->real
        transforms

1999-03-28  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * 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)

1999-03-26  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * doc/fftw.texi, FAQ/fftw-faq.bfnn, NEWS:
        Updated documentation for FFTW 2.1.1.

        * configure.in:
        Updated version number for 2.1.1 (as well as shared lib. version).

        * threads/Makefile.am, mpi/Makefile.am: Fixed typo in comment.

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

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

1999-03-25  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * tests/test_main.c, tests/test_main.h, tests/rfftw_test.c,
        tests/fftw_test.c, fftw/planner.c:
        Added hooks for paranoid verification of every single plan.

1999-03-23  Matteo Frigo  <athena@stern.lcs.mit.edu>

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

1999-03-09  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

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

1999-03-08  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * 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.

1999-03-08  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * 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.

1999-03-08  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * ChangeLog: Updated

        * configure.in: Updated version number

1999-03-07  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * doc/fftw.texi: a_slow_array --> a_bad_array

        * doc/fftw.texi:
        Removed all reference to performance from "Dynamic Arrays--The
        Wrong Way" section.

        Clarified output parameter of Fortran multi-dimensional in-place
        transforms.

        Thanks to Erik Scheirer (boom@sonyx.com) for testing the Mach C
        threads code.

1999-03-06  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * mpi/fftw_mpi_test.c: Added undocumented --only-parallel flag.

        * threads/rfftw_f77_threads.c, threads/fftw_f77_threads.c,

        Added Fortran-callable wrappers for the multi-threaded routines.

1999-02-25  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * threads/fftw_threads.c, threads/fftw_threads-int.h:
        Made pthreads code more tolerant if user doesn't call
        fftw_threads_init.

        * tests/rfftw_test.c, tests/fftw_test.c, mpi/rfftw_mpi_test.c,
        mpi/fftw_mpi_test.c:
        Reduced array sizes somewhat for planner tests.

        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.

1999-02-23  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * doc/fftw.texi: Fixed typo.

        * doc/fftw.texi: Indentation fix.

1999-02-22  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * ChangeLog: Updated

1999-02-22  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * 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.

1999-02-22  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * 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

1999-02-22  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * tests/test_main.c:
        Added some new jokes.  Also, print out floating-point precision
        for -v.

        * 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

        * 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

1999-02-21  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * 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.

        * 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: Use g77 in preference to fort77.

1999-02-21  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * tests/Makefile.am: Fixed forgotted XXX_FFTW_NAME_XXX

        * configure.in: Allowed user specification of [r]fftw-name

1999-02-21  fftw  <fftw@stern.lcs.mit.edu>

        * 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: Incremented shared library version number.

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

1999-02-20  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * 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.

1999-02-20  fftw  <fftw@stern.lcs.mit.edu>

        * doc/fftw.texi: Minor tweaks

1999-02-20  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * doc/Makefile.am, doc/rfftwnd.gif: fig2dev gif output stinks;
        "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.

1999-02-19  Matteo Frigo  <athena@stern.lcs.mit.edu>

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

1999-02-19  fftw  <fftw@stern.lcs.mit.edu>

        * 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

1999-02-19  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * fftw/config.h.in, threads/fftw_threads-int.h, configure.in,
        doc/fftw.texi, NEWS: Added untested support for Mach C threads.
        Also changed three --with options to --enable.

        * doc/rfftwnd.gif, doc/fftw.texi, doc/Makefile.am: Added rfftwnd
        illustration to the manual (HTML version only).

1999-02-18  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * doc/fftw.texi: rfftwnd_mpi documentation bug fix.

1999-02-16  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * doc/fftw.texi: Noted library requirements of 1D MPI.

        * mpi/fftw_mpi.h, mpi/fftw_mpi.c, doc/fftw.texi: Added scrambled
        input/output options (flags) for 1d mpi transforms.

        Caltech.

        * NEWS, doc/fftw.texi: Documented real MPI transforms.

        * mpi/rfftw_mpi_test.c: Small fix.

1999-02-15  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * mpi/rfftw_mpi_test.c, mpi/rfftwnd_mpi.c, mpi/fftw_mpi_test.c,
        mpi/rfftw_mpi.h, configure.in, mpi/Makefile.am: Added rfftw MPI
        transforms.

        * mpi/transpose_mpi.h: this header file is now part of fftw_mpi.h

        * 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.

1999-02-14  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

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

        * fftw/malloc.c: Whoops!

        * fftw/malloc.c: fixed omission from last checkin.

        * configure.in: Fixed typo and updated version number to 2.1.

        * mpi/transpose_mpi.c, mpi/time_fftwnd_mpi.c,
        mpi/test_transpose_mpi.c, mpi/test_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
        wrapper files in sources.

        * mpi/transpose_mpi.c, mpi/test_transpose_mpi.c,
        mpi/time_fftwnd_mpi.c, mpi/fftwnd_mpi.h, mpi/sched.c,

        mpi/test_transpose_mpi.c, mpi/time_fftwnd_mpi.c, mpi/sched.h,
        mpi/test_fftwnd_mpi.c, mpi/test_sched.c, mpi/fftwnd_mpi.h,
        mpi/sched.c, mpi/TOMS_transpose.c, mpi/TOMS_transpose.h,
        mpi/fftwnd_mpi.c, mpi/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/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).

1999-02-11  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

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

        * rfftw/rfftwf77.c, fortran/rfftw_f77.c, fortran/fortranize.h,

        fortran/f77_test.F, 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.

1999-02-10  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * doc/fftw.texi: Small fixes to multi-threaded FFTW section.

        * threads/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/rfftwnd_threads.c, threads/rfftw_threads.h,
        threads/rfftw_threads_test.c, threads/rexec2_threads.c,
        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),

1999-02-05  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

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

        tests/test_main.h, tests/rfftw_test.c, configure.in,
        tests/fftw_test.c: Made the threads test program follow the model
        of the uniprocessor test programs.

        * doc/fftw.texi: Documented --with-threads configure option.

        * threads/time_threads.c, threads/Makefile.am, threads/README,
        threads/fftw_threads.h, threads/test_threads.c, threads/Makefile,
        configure.in, fftw/config.h.in, Makefile.am, NEWS: Autoconfiscated
        threads stuff.

1999-02-01  fftw  <fftw@stern.lcs.mit.edu>

        * FAQ/fftw-faq.bfnn: Added entry about VC++ 5.0

1999-01-29  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * 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
        interactive mode.

1999-01-29  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * tests/test_main.c, tests/test_main.h, tests/rfftw_test.c,
        tests/fftw_test.c, tests/Makefile.am, tests/README, ChangeLog:
        Allow specification of dimensions in ND test program.

1998-12-11  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * fftw/malloc.c: Use typedefs consistently for fftw_*_hook.

        * doc/fftw.texi: Updated Cilk URL.

1998-11-11  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * tests/test_main.c: Print FFTW version on -v.

        * tests/Makefile.am: Removed explicit -lm -- it is added
        automatically by configure when it is available.

1998-10-19  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * 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.

1998-10-07  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

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

1998-10-06  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * 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.

1998-10-01  Matteo Frigo  <athena@stern.lcs.mit.edu>

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

1998-09-29  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * FAQ/fftw-faq.bfnn, README: Don't mention the current version
        number, so that we don't have to keep updating these files with
        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.

1998-09-28  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * tests/test_main.c: Deleted some unused variables.

1998-09-28  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * fftw/wisdom.c, fftw/config.h.in, fftw/executor.c, Makefile.am,
        configure.in: Moved version number to configure.in and tweaked
        make dist to change config.h with the right version number.

1998-09-27  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * FAQ/fftw-faq.bfnn, NEWS: Noted bug fixes for large rfftwnd
        transforms in 2.0.1.

        * tests/rfftw_test.c: Fixed bug in -s for large multi-dimensional
        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.

1998-09-26  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

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

1998-09-25  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * NEWS: Some small changes to 2.0.1 release notes.

1998-09-25  Matteo Frigo  <athena@stern.lcs.mit.edu>

        * gensrc/Makefile.rfftw.am, gensrc/exprdag.ml,
        gensrc/Makefile.fftw.am, NEWS, configure.in, ChangeLog: Changed
        version numbers for 2.0.1 release.

        * tests/fftw_test.c: Added FFTW_OUT_OF_PLACE to flags just in case
        we forget it again in the header file.

        * gensrc/magic.ml, gensrc/genfft.ml, gensrc/exprdag.ml: Added a
        couple of hacks useful for athenafft

1998-09-24  Matteo Frigo  <athena@theory.lcs.mit.edu>

1998-09-23  Matteo Frigo  <athena@theory.lcs.mit.edu>

        * fftw/fftw.h.in, doc/fftw.texi: Added definition of
        FFTW_OUT_OF_PLACE and fixed typo.

1998-09-23  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * doc/fftw.texi: Noted how to compile in single precision in
        installation for non-unix section.

1998-09-18  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * 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.

1998-09-17  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * tests/test_main.c, tests/test_main.h, tests/rfftw_test.c,
        tests/fftw_test.c: Added -e flag to use FFTW_ESTIMATE in speed
        tests.
        
1998-09-16  Matteo Frigo  <athena@theory.lcs.mit.edu>

        * rfftw/rplanner.c, fftw/planner.c: Do not use twiddle(1)
        codelets, even if somebody (like me :-)) includes them
        accidentally in [r]config.c.

1998-09-15  Matteo Frigo  <athena@theory.lcs.mit.edu>

        * doc/fftw.texi: Fixed typo 0 <= i instead of 0 < i

1998-09-15  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * doc/fftw.texi: Added hyphen.

1998-09-15  Matteo Frigo  <athena@theory.lcs.mit.edu>

        * gensrc/variable.ml, gensrc/number.ml, gensrc/exprdag.ml: Better
        hashing scheme for variables.  Removed caching of float value of
        Numbers since it makes little difference with the new hashing
        scheme.

1998-09-15  Matteo Frigo  <athena@theory.lcs.mit.edu>

        * gensrc/number.ml, gensrc/exprdag.ml: Made oracle smarter (as it
        was in 2.0)

1998-09-14  Matteo Frigo  <athena@theory.lcs.mit.edu>

        * gensrc/variable.mli, gensrc/number.ml, gensrc/variable.ml,

        gensrc/magic.ml, gensrc/exprdag.ml, gensrc/Makefile.genfft: Added
        informative messages

        * gensrc/variable.mli, gensrc/to_c.ml, gensrc/variable.ml,
        gensrc/fft.ml, gensrc/exprdag.ml, gensrc/exprdag.mli,
        gensrc/expr.ml, gensrc/expr.mli, gensrc/complex.mli,
        gensrc/asched.ml, gensrc/complex.ml: Added LittleSimplifier to do
        a first quick simplification pass.  This speeds up the algebraic
        simplifier a lot.

1998-09-14  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * doc/fftw.texi: Fixed library ordering for -lrfftw.

1998-09-13  Matteo Frigo  <athena@theory.lcs.mit.edu>

        * gensrc/number.mli, gensrc/fft.ml, gensrc/number.ml,
        gensrc/exprdag.mli, gensrc/complex.mli, gensrc/exprdag.ml,
        gensrc/complex.ml: Improved speed of generator

1998-09-11  Matteo Frigo  <athena@theory.lcs.mit.edu>

        * acinclude.m4: Dec's compiler does not like -malign-double.

1998-09-11  Steven G. Johnson  <stevenj@stern.lcs.mit.edu>

        * acinclude.m4: Make sure ACX_PROG_CC_EGCS is called.

1998-09-11  Matteo Frigo  <athena@theory.lcs.mit.edu>

        rfftw/rfftwint.h, rfftw/rexec2.c, rfftw/rexec.c, fftw/executor.c:
        Inlined i386 hacks.  This is almost completely portable because of
        the new alloca() trick.  Code is much cleaner now.

        * doc/fftw.texi: Described rfftwnd complex format, and discussed
        meaning of stride/dist for in-place transforms.

        * doc/fftw.texi: Made it clear that halfcomplex applies to
        one-dimensional rfftw only.

        * doc/fftw.texi: Fixed html versions of halfcomplex dfn.

        * doc/texi2html, doc/fftw.texi: Added a few missing html formulas

        * doc/fftw.texi: Some minor changes.  Removed mention of
        "halfcomplex" in reference to rfftwnd outputs, since we define
        that word in terms of the rfftw output format.

        * doc/fftw.texi: Added What RFFTW Really Computes section

        * doc/fftw.texi, doc/Makefile.am: Added index

        * rfftw/rexec.c, fftw/fftw-int.h, fftw/executor.c,
        fftw/config.h.in, configure.in: I386_HACK Done Right.  The hack
        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
        seem to be well-defined in the HTML standard).

        * rfftw/rfftw.h: Changed rfftw.h to reflect the manual.

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

        with the shared library.

        * doc/texi2html: @math used to translate to italics, which looked
        ugly in HTML; now does nothing.

        * doc/fftw.texi: Several small changes.  Gave uref's readable
        titles.  Removed @inforef, which looked ugly in non-info docs.

        * doc/fftw.texi: Worked on installation guide

        * doc/fftw.texi: Added draft or real-complex reference.

        * doc/texi2html, doc/fftw.texi: Upgraded to latest texi2html.

        * configure.in: Use -qansialias on RS/6000 (seems to cause a
        miniscule improvement).

        * doc/fftw.texi: Several small changes.

1998-08-24  fftw  <fftw@stern.lcs.mit.edu>

        a decent way to incorporate them back.

        * FAQ/fftw-faq.bfnn: Added entry for broken linuxthreads.

        * doc/fftw.texi: Updated introduction

1998-08-21  fftw  <fftw@stern.lcs.mit.edu>

        * gensrc/util.mli, gensrc/util.ml, gensrc/symmetry.ml,
        gensrc/fft.ml: Fixes to improve speed of generator and op count
        for n not squarefree.

1998-08-20  fftw  <fftw@stern.lcs.mit.edu>

        * doc/fftw.texi: Grammar fix.

        * doc/fftw.texi: Recommend that quick starts be read in order.

        * rfftw/rfftwnd.c: dist parameter for in-place transforms now
        works more closely like what you might expect.

        * 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: Wrote rfftw quick start.

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

1998-08-19  fftw  <fftw@stern.lcs.mit.edu>

        * doc/fftw.texi: Changed reference in the introduction--an
        introductory book is a better reference for people who don't know
        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.

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

        * fortran/README: Fixed erroneous listing of rfftwnd.

        * fortran/fortranize.h, fortran/README: Various improvements.

        fortran/fftw_f77.c, fortran/README: Added rfftw wrappers.

1998-08-18  fftw  <fftw@stern.lcs.mit.edu>

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

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

        * rfftw/rplanner.c, rfftw/rgeneric.c, rfftw/rfftwnd.c,
        rfftw/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.

1998-08-17  fftw  <fftw@stern.lcs.mit.edu>

        * 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/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.

1998-08-16  fftw  <fftw@stern.lcs.mit.edu>

        * 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.

1998-08-15  fftw  <fftw@stern.lcs.mit.edu>

        * NEWS: Noted the news.

        * threads/Makefile, tests/Makefile.am, mpi/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.

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

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

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

        * src/rader.c, src/fftw.h.in, src/fftw-int.h, src/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.

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

1998-08-14  fftw  <fftw@stern.lcs.mit.edu>

        * rfftw/rgeneric.c: rgeneric seems to work!

        * rfftw/rgeneric.c: Fixed yet another bug in rgeneric.

        * rfftw/rexec.c: Fixed wrong union field.

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

        * src/putils.c, src/generic.c, src/fftw.h.in, src/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).

        * src/wisdom.c, src/twiddle.c, src/timer.c, src/putils.c,
        src/planner.c, src/malloc.c, src/generic.c, src/fftwnd.c,
        src/fftw.h.in, src/fftw-int.h, src/config.h.in, src/.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, src/putils.c, src/planner.c, src/generic.c,
        src/fftw-int.h, src/.indent.pro, rfftw/rplanner.c,
        rfftw/rfftwnd.c, rfftw/rfftw.h, rfftw/rexec2.c, rfftw/rexec.c,
        rfftw/.indent.pro, gensrc/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

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

        * tests/rfftw_test.c, rfftw/rfftwnd.c: Fixed more bugs in in-place
        rfftwnd (not done yet...sigh).

        * rfftw/rfftwnd.c, rfftw/rexec2.c, rfftw/rexec.c: Fixed bug in
        rfftwnd for ((n+1)/2)%4 == 0.

1998-08-13  fftw  <fftw@stern.lcs.mit.edu>

        * rfftw/rexec2.c: Removed redundant statement.

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

        * src/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().

        * src/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.

        * src/fftw-int.h, src/executor.c, rfftw/rexec.c, gensrc/to_c.ml,
        gensrc/magic.ml, gensrc/genfft.ml, gensrc/Makefile.sources: Added
        automatic alignment checker --- this will make life easier on the
        x86

        * src/wisdom.c: Fixed incorrect order of arguments.

        * src/wisdom.c, src/twiddle.c, src/planner.c, src/fftw-int.h,
        src/executor.c, src/.indent.pro, rfftw/rplanner.c,
        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.

        * tests/rfftw_test.c: Fixed bug in test.

        * tests/rfftw_test.c: First version of rfftw_test (incomplete).

        * tests/test_main.h, tests/test_main.c, tests/fftw_test.c,
        tests/Makefile.am, rfftw/rfftwnd.c: Initial version of rfftw_test
        (incomplete).

        * gensrc/Makefile: 'make clean' now gets rid of files from aborted
        make install.

        * gensrc/Makefile.rfftw.am: Added rfftwnd & friends to makefile.

        * tests/test_main.h, tests/test_main.c, tests/fftw_test.c,
        tests/Makefile.am: Split off main portion of fftw_test.c so that
        it can be reused for rfftw_test.

        * src/fftwnd.c, src/fftw-int.h, rfftw/rfftwnd.c, rfftw/rfftw.h,
        rfftw/rexec2.c, rfftw/rexec.c: Added preliminary rfftwnd.c,
        modifying other files as necessary.

        * gensrc/number.mli, gensrc/number.ml, gensrc/exprdag.ml,
        gensrc/expr.mli, gensrc/expr.ml: Added post-optimization pass to
        simplify K1*(K2*A+K3*B), where Ki is a number

        * rfftw/rfftw.h, rfftw/rexec2.c, rfftw/rexec.c: Added rexec2 in
        preparation for rfftwnd transforms.

        * rfftw/README: Removed out-of-date rfftw/README.  We will need to
        add a couple of sections to the main manual.

1998-08-12  fftw  <fftw@stern.lcs.mit.edu>

        * src/twiddle.c, src/planner.c, src/fftw.h.in, src/fftw-int.h,

        gensrc/config_prelude, gensrc/Makefile.rfftw.am,
        gensrc/Makefile.am, gensrc/Makefile, configure.in: First version
        of rfftw executor and friends.

        * gensrc/config, gensrc/Makefile.sources: Updated for real
        transforms

        * gensrc/polygen.ml, gensrc/poly.ml, gensrc/factorizer.ml,
        gensrc/Makefile.genfft: Removed old unused files

        * gensrc/variable.mli, gensrc/variable.ml, gensrc/symmetry.ml,
        gensrc/genfft.ml, gensrc/fft.ml, gensrc/complex.mli,
        gensrc/complex.ml, gensrc/Makefile.genfft: Added hc2hc_backward
        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/variable.mli, gensrc/variable.ml, gensrc/magic.ml,
        gensrc/genfft.ml, gensrc/dag.ml, gensrc/Makefile.genfft: Removed
        old junk code.

        * gensrc/twiddle.ml, gensrc/genfft.ml, gensrc/fft.ml,
        gensrc/Makefile.genfft: Separated twiddle policies into new file.
        Added DIF twiddle code.

1998-08-11  fftw  <fftw@stern.lcs.mit.edu>

        * 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

1998-08-10  fftw  <fftw@stern.lcs.mit.edu>

        * 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

1998-08-08  fftw  <fftw@stern.lcs.mit.edu>

        * threads/fftwnd_threads.c, tests/fftw_test.c, src/wisdom.c,
        src/twiddle.c, src/planner.c, src/malloc.c, rfftw/rfftw.c,
        gensrc/genfft.ml: Reverted NULL -> (foo *) 0

        * threads/fftwnd_threads.c, tests/fftw_test.c, src/wisdom.c,
        src/twiddle.c, src/planner.c, src/malloc.c, rfftw/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).

1998-08-07  fftw  <fftw@stern.lcs.mit.edu>

        * ChangeLog: Updated changelog

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

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

1998-08-06  fftw  <fftw@stern.lcs.mit.edu>

        * src/wisdomio.c, src/common_io.c, gensrc/Makefile.am: Changed
        common_io.c -> wisdomio.c to meet 8.3 filename restriction.
        (sigh)

1998-08-02  fftw  <fftw@stern.lcs.mit.edu>

        * src/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.)

1998-07-31  fftw  <fftw@stern.lcs.mit.edu>

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

1998-07-28  fftw  <fftw@stern.lcs.mit.edu>

        * configure.in: Note default CFLAGS in configure message when
        machine is unknown.

        * doc/fftw.texi: Added more concrete example of how to save &
        restore plans using wisdom.

1998-07-03  fftw  <fftw@stern.lcs.mit.edu>

        * threads/fftw_threads.h: Noted that nthreads is modified by the
        spawn_loop macro.

1998-06-25  fftw  <fftw@stern.lcs.mit.edu>

        * FAQ/fftw-faq.bfnn: Noted that you shouldn't recreate the plan
        before every transform.

1998-06-15  fftw  <fftw@stern.lcs.mit.edu>

        * src/fftw-int.h: Fixed bug in pentium timer runes

1998-06-14  fftw  <fftw@stern.lcs.mit.edu>

        policy

        * doc/fftw.texi, doc/Makefile.am, doc/Makefile, configure.in,
        Makefile.am: Put documentation under automake control.

1998-06-11  fftw  <fftw@stern.lcs.mit.edu>

        * NEWS: V, V. -> Version

        * INSTALL: Added FFTW-specific introduction.  I'm still not happy
        with this file.

        * Makefile.am: Added cilk/ to list of distributed directories

        * doc/fftw.texi: Minor fixes.

        * tests/fftw_test.c: Used the word "consistency" rather than
        "accuracy" when describing the output of fftw_test -t.

        * src/malloc.c, src/config.h.in, configure.in: Added
        --enable-debug option; supercedes old MALLOC_DEBUG flag in
        malloc.c.

        * gensrc/Makefile.am: Fixed bug in makefile

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

1998-06-11  Matteo Frigo  <athena@glauke.lcs.mit.edu>

        * Added libtool support for shared libraries
