	systems.

2006-03-04  Steven G. Johnson  <stevenj@fftw.org>

	* doc/fftw3.texi: whoops

	* doc/fftw3.texi: note that we align the stack ourselves if
	necessary, with gcc and icc

	* doc/fftw3.texi: clearer distinction between static and automatic
	storage in C

2006-02-26  Steven G. Johnson  <stevenj@fftw.org>

	* libbench2/verify-lib.c: rm unused var

2006-02-25  Matteo Frigo  <athena@fftw.org>

	* libbench2/my-getopt.c: Improved usage of goto (Dijkstra miserere
	nostri)

2006-02-12  Matteo Frigo  <athena@fftw.org>

	* dft/simd/Makefile.am, dft/simd/codelets/Makefile.am,
	dft/simd/t3b.h, dft/simd/t3f.h, genfft/algsimp.ml,
	genfft/annotate.ml, genfft/c.ml, genfft/c.mli, genfft/complex.ml,

	* dft/simd/Makefile.am, dft/simd/codelets/Makefile.am,
	dft/simd/t1s.c, dft/simd/t1s.h, dft/simd/ts.c, dft/simd/ts.h,
	genfft/twiddle.ml: Added support for t2-style simd split-complex
	codelets.

2006-02-10  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_openmp.m4: *** empty log message ***

	* m4/ax_openmp.m4: punctuation

	* api/f77api.c, api/f77funcs.h: windows DLL stuff for Fortran
	interface

2006-02-10  Matteo Frigo  <athena@fftw.org>

	* configure.ac: Bumped version to 3.1.1

	* kernel/ifftw.h: Precompute array indices on x86-64.  Speeds up
	Pentium IV and makes no appreciable difference on AMD.

2006-02-08  Matteo Frigo  <athena@fftw.org>

	* simd/Makefile.am, simd/sse.c, simd/sse2.c, simd/x86-cpuid.h:

	* kernel/primes.c: whoops, fixed assert (y <= x)

	* kernel/primes.c: note that safe_mulmod requires {x,y} < p (or at
	least < 2p), and added assert

2006-01-30  Matteo Frigo  <athena@fftw.org>

	* libbench2/bench-user.h, libbench2/timer.c: fixed aix/xlc lossage

	* libbench2/verify-lib.c: In the impuse test, normalize the
	impulse so that the impulse and the random vectors have roughly
	the same L2 norm.  This change reduces the number of bits that we
	lose because of floating-point cancellation, so that we can focus
	on the bits that we lose because of bugs.

	* rdft/dht-rader.c: Compute omega in trigreal precision, as
	opposed to R.

2006-01-28  Steven G. Johnson  <stevenj@fftw.org>

	* Makefile.am, configure.ac, tests/Makefile.am,
	threads/Makefile.am, tools/Makefile.am: add
	--with-combined-threads option as workaround to Windows inability
	to build shared libs with dependencies

2006-01-27  Steven G. Johnson  <stevenj@fftw.org>

	* threads/Makefile.am: libfftw3_threads should *not* used
	-no-undefined because, in fact, it is not true -- this library
	depends on -lfftw3, and is not self-contained

	* NEWS: updated

2006-01-27  Matteo Frigo  <athena@fftw.org>

	* api/apiplan.c, dft/bluestein.c, dft/buffered.c, dft/ct.c,

	threads/rdft-vrank-geq1.c, threads/vrank-geq1-rdft2.c: Added
	paranoid stack alignment when awaking plans.  While I was at it,
	removed obsolete, redundant AWAKE macro.

	* NEWS: Updated for 3.1.

	* TODO, libbench2/bench-main.c: ditched one alignment check and
	noted that we should eliminate the rest as well

2006-01-26  Matteo Frigo  <athena@fftw.org>

	* libbench2/bench-main.c: alignment hack

	* m4/ax_gcc_archflag.m4: detect pentium M

2006-01-25  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_gcc_archflag.m4: don't trust host_cpu if it claims we are
	on i386/i486, and call cpuid anyway (if it fails we use no arch
	flag).  This is needed on FreeBSD

	* kernel/kalloc.c: suggest --with-our-malloc16 in error message

	* configure.ac: ditto for -no-gcc

	* configure.ac: flags required for successfull compilation should
	be added even if the user overrides CFLAGS

2006-01-24  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_openmp.m4: upcoming gcc OpenMP support uses -fopenmp

	* m4/ax_openmp.m4: note that PGI uses -mp as well

2006-01-23  Matteo Frigo  <athena@fftw.org>

	* kernel/cycle.h, simd/sse.c, simd/sse2.c: my best guess at how to
	fix the microsoft crap du jour

2006-01-23  Steven G. Johnson  <stevenj@fftw.org>

	* configure.ac, kernel/cycle.h: use -Masmkeyword for PGI cycle
	counter, grr

2006-01-22  Matteo Frigo  <athena@fftw.org>

	* configure.ac: Bumped version number to 3.1.

2006-01-21  Matteo Frigo  <athena@fftw.org>

	* configure.ac: Report that --enable-k7 is incompatible with
	--enable-shared.

	* Makefile.am: Do not use empty libraries in LIBADD, since
	otherwise the linker fails on Solaris.

2006-01-18  Steven G. Johnson  <stevenj@fftw.org>

	* bootstrap.sh: warn end-users away from this file

2006-01-17  Matteo Frigo  <athena@fftw.org>

	* simd/simd-sse.h: Gcc sucks.

	* tests/hook.c: Disabled checks that may turn out to be too
	paranoid.

	* tests/hook.c: Some paranoid checks.

	* libbench2/ovtpvt.c: Flush stdout after printing.

	* kernel/alloc.c, tests/bench.c: Run the leak detector in all
	cases, not just when verbose > 2.

	* api/mapflags.c: Eliminate calls to pow(), rint().

2006-01-17  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/ifftw.h: put # in first column, for stylistic consistency

2006-01-17  Matteo Frigo  <athena@fftw.org>

	* api/mapflags.c, kernel/ifftw.h, kernel/planner.c: Made timeout
	part of impatience flags, in order to improve the usability of
	wisdom.  Also, fixed bogus error recovery logic in
	planner.c:imprt().

2006-01-17  Steven G. Johnson  <stevenj@fftw.org>

	* api/apiplan.c, api/fftw3.h, doc/fftw3.texi, kernel/planner.c:
	make timelimit < 0 .eq. FFTW_NO_TIMELIMIT

2006-01-17  Matteo Frigo  <athena@fftw.org>

	* api/apiplan.c, api/fftw3.h, api/the-planner.c, doc/fftw3.texi,
	kernel/planner.c, tests/bench.c: Eliminated the FFTW_TIMELIMIT
	flag in favor of this simpler logic: fftw_set_timelimit(0)
	disables time limit.  fftw_set_timelimit(X), X>0 sets the time
	limit to X.

2006-01-16  Matteo Frigo  <athena@fftw.org>

	* api/apiplan.c: Force the use of the estimator when wisdom fails
	because of md5 collisions, otherwise the planner takes forever.

	* kernel/ifftw.h: Ranted about how broken gcc-4 is.

2006-01-16  Steven G. Johnson  <stevenj@fftw.org>

	* api/apiplan.c, api/fftw3.h, doc/fftw3.texi, tests/bench.c:
	change fftw_timelimit global var to fftw_set_timelimit(double)
	function, for simpler usage with shared libraries and for
	consistency with e.g. set_numthreads

2006-01-16  Matteo Frigo  <athena@fftw.org>

	* doc/fftw3.texi: Minor tweaks.

2006-01-15  Matteo Frigo  <athena@fftw.org>

	* libbench2/timer.c: tweaks to make sure that time_n() is always
	called from the same stack position.

	* libbench2/bench.h, libbench2/speed.c, libbench2/timer.c,
	libbench2/timer2.c: Major simplification of the timer calibration
	logic.  Also, use an FFT as a unit of work instead of the old
	pointer chasing, because God knows how pointer chasing interacts
	with the idiotic cache-hit speculation on the Pentium IV.

	* kernel/align.c: Fixed broken aligment checks when sizeof(R)==12.

	* libbench2/timer2.c: Manual unrolling of loop.

	* libbench2/Makefile.am, libbench2/bench.h, libbench2/timer.c,
	libbench2/timer2.c: Various improvements to timer calibration
	routines.

	* libbench2/timer.c: cygwin defines __CYGWIN__, not __WIN32__ etc.

	* libbench2/bench-user.h, libbench2/speed.c, libbench2/timer.c,
	tests/bench.c: fixed confusion between libbench and user timers

	* configure.ac: Switched to -beta2.

2006-01-13  Matteo Frigo  <athena@fftw.org>

	* rdft/buffered.c, rdft/indirect.c, rdft/problem.c,
	rdft/rank0-rdft2.c, rdft/rdft.h, rdft/vrank3-transpose.c: Fixed
	technically correct but highly obfuscated use of the enum tag R2HC
	as a null pointer.

2006-01-13  Steven G. Johnson  <stevenj@fftw.org>

	* configure.ac: --enable-unsafe-mulmod is obsolete

2006-01-13  Matteo Frigo  <athena@fftw.org>

	* TODO: More thoughts.

	* rdft/buffered2.c: Removed loop unrolling because it slows things
	down on at least one powerpc and it generates clumsy x86 code.

2006-01-13  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/kalloc.c: tweaks

2006-01-12  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/ifftw.h: MacOSX x86 ABI specifies that the stack is kept
	16-byte aligned

2006-01-12  Matteo Frigo  <athena@fftw.org>

	* kernel/cycle.h: ``ret'' is a reserved word in the evil empire.

	* simd/sse2.c, simd/sse.c: Changed ret => result because ret ``is
	a reserved word'' in the evil empire.

	* simd/simd-sse2.h: Workaround Visual c++ lossage.

	* simd/simd-sse.h: Workaround visual c++ lossage.

	* libbench2/getopt-utils.c: isprint() is guaranteed to work for
	unsigned char + EOF only.

2006-01-11  Steven G. Johnson  <stevenj@fftw.org>

	* rdft/vrank3-transpose.c: rm obsolete fixme

	* rdft/vrank3-transpose.c: *** empty log message ***

	* rdft/vrank3-transpose.c: fix comment

2006-01-11  Matteo Frigo  <athena@fftw.org>

	* dft/bluestein.c, rdft/buffered2.c, rdft/dht-rader.c,
	rdft/rank0-rdft2.c, reodft/rodft00e-r2hc-pad.c: Paranoid use of
	K(x) for all constants x, to avoid runtime double->float
	conversions on sufficiently stupid compilers.

	* simd/simd-sse.h: Workaround to gcc nonsense.

2006-01-10  Steven G. Johnson  <stevenj@fftw.org>

	* rdft/vrank3-transpose.c: bug fix: infinite loop in transpose-cut
	planning

	* api/fftw3.h: clarified comment

	* tests/bench.c: more Windows decorations

	* support/Makefile.codelets: added FIXME comment

	* support/Makefile.codelets: 'make clean' should not delete
	codlist.c since it is included in the dist tarball

2006-01-10  Matteo Frigo  <athena@fftw.org>

	* dft/dftw-direct.c: Change threshold for ``large'' Cooley-Tukey
	to 256K from 64K, since it seems to benefit the Pentium IV with
	sse and the planning cost is not too horrible.

2006-01-10  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/ifftw.h: more missing Windows DLL decorations

	* rdft/dht-rader.c: remove unused var

	* threads/threads.c: allow compiler threads, if enabled, to take
	precedence over explicit threads

	* api/api.h, kernel/planner.c: *** empty log message ***

2006-01-10  Matteo Frigo  <athena@fftw.org>

	* kernel/planner.c: Fixed comment typo.

	* kernel/planner.c: Rearranged timeout checks so as to eliminate
	one of them.

	* kernel/plan.c: Converted residual CK() -> A().

	* kernel/planner.c: Maintain the invariant TIMED_OUT ==>
	NEED_TIMEOUT_CHECK.

	* tests/hook.c: Assertions.

2006-01-10  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/timer.c: some condensing

	* api/apiplan.c, kernel/ifftw.h, kernel/planner.c, kernel/timer.c:
	eliminate X(seconds) in favor of X(elapsed_since), in paranoia of
	clock wrap

	* kernel/timer.c: *** empty log message ***

	* kernel/timer.c: hmm, a bit more pessimistic about clock wrapping

2006-01-10  Matteo Frigo  <athena@fftw.org>

	* configure.ac, kernel/ifftw.h: Revert to md5uint = unsigned int
	whenever possible, so as to avoid wasting space for unsigned long
	on 64-bit machines.

2006-01-10  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/timer.c: note why clock() wrap should not be a concern

	* kernel/planner.c: bugfix in recent timeout changes - check for
	case where last solver times out

	* NEWS: started changes list from beta

2006-01-10  Matteo Frigo  <athena@fftw.org>

	* api/mapflags.c: Paranoia.

	* kernel/planner.c: Paranoid assertions.

	* tests/hook.c: Added FIXME comment stating the 64-bit
	uncleaniness of fftw_tensor_to_bench_tensor().

	* dft/simd/t.c: Another 64-bit bug.

2006-01-10  Steven G. Johnson  <stevenj@fftw.org>

	* api/api.h, kernel/ifftw.h, tests/hook.c: more Windows DLL
	nonsense

	* api/api.h, kernel/ifftw.h: some additional dllexport tags
	required to build the test program, due to internal stuff called
	by hook.c

	* api/fftw3.h: *** empty log message ***

	* api/fftw3.h: comment

	* api/fftw3.h, api/api.h: *** empty log message ***

	* api/fftw3.h: clarification

	* api/api.h: define FFTW_DLL if DLL_EXPORT (defined by libtool) is
	supplied

	* api/fftw3.h: whoops

	* api/fftw3.h: another stab at Windows DLL mess

2006-01-10  Matteo Frigo  <athena@fftw.org>

	* simd/simd-altivec.h, simd/simd-sse.h, simd/simd-sse2.h: 64-bit
	clean SIMD header file.  I missed those because sparse does not
	know vector types.  Grrr...

2006-01-10  Steven G. Johnson  <stevenj@fftw.org>

	* configure.ac: this option is called AC_DISABLE_SHARED in the
	documentation

2006-01-09  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_gcc_archflag.m4: fixed --with-gcc-arch to work when
	cross-compiling

2006-01-09  Matteo Frigo  <athena@fftw.org>

	* api/apiplan.c, kernel/ifftw.h, kernel/planner.c: Moved the
	timeout check back into the search loop, sicut erat in principio.
	This gives us a precise control over the timeout.  To avoid the
	overhead of X(seconds)(), only call X(seconds)() if some time
	measurement was taken since the last call to X(seconds)().

2006-01-09  Steven G. Johnson  <stevenj@fftw.org>

	* rdft/vrank3-transpose.c: comments

	* rdft/vrank3-transpose.c: generalized transpose-cut routine to be
	able to call transpose-gcd recursivly; TOMS follow-the-cycles
	algorithm now seems to be completely superseded

	* threads/threads.c: *** empty log message ***

	* threads/threads.c: ignore errors from setscope -- POSIX standard
	does not require PTHREAD_SCOPE_SYSTEM to be supported, and
	PTHREAD_SCOPE_PROCESS is usually okay in that case

2006-01-08  Steven G. Johnson  <stevenj@fftw.org>

	* rdft/vrank3-transpose.c: added TODO comment

	* rdft/vrank3-transpose.c: whoops

2006-01-08  Matteo Frigo  <athena@fftw.org>

	* NEWS: Boasted ``much faster altivec performance''.

	* configure.ac, dft/simd/codelets/Makefile.am, genfft/annotate.ml,
	genfft/magic.ml, genfft/schedule.ml, support/Makefile.codelets,
	support/twovers.sh: Added a new pass to the generator to schedule
	for the pipeline latency.  (This schedule modifies the ``optimal''
	cache-oblivious schedule and hence it uses more registers.)

	This pass is currently:

	* disabled for non-fma code, under the assumption that this will
	  run on a register-starved fma.

	* enabled for non-simd fma code, under the assumption that this
	  will run on a processor with 32 or more FP registers.  The
	  latency of 4 is conservative and does not introduce too much
	  register pressure.

	* enabled for simd fma code, under the assumption that this will
	  run on altivec.  The latency of 8 seems to produce the best
	  results.

2006-01-08  Steven G. Johnson  <stevenj@fftw.org>

	* rdft/vrank3-transpose.c: fixed estimator for vrank3-transpose

	* NEWS: more detail on VC++ workaround

	* rdft/vrank3-transpose.c: typo

	* rdft/vrank3-transpose.c: screw it, just use planner for all
	sub-transposes in vrank3-transpose (still just use memcpy for
	contiguous copies, though)

	* kernel/tile2d.c: add an assert

	* kernel/ifftw.h, rdft/rank0.c, rdft/vrank3-transpose.c:
	vrank3-transpose now uses planner to decide whether to use cpy2d,
	cpy2d_tiled, etc.

	* kernel/primes.c: too annoying to have isqrt unexpectedly fail
	for n==0

2006-01-07  Steven G. Johnson  <stevenj@fftw.org>

	* NEWS, doc/fftw3.texi: clarifications

	* rdft/vrank3-transpose.c: comment fix

	* doc/FAQ/fftw-faq.bfnn: more faq updates

	* configure.ac, doc/FAQ/fftw-faq.bfnn: enable fma on hppa, update
	FAQ entry

2006-01-07  Matteo Frigo  <athena@fftw.org>

	* dft/simd/t.c: Accomodate different semantics of 'const' in C and
	C++

	* NEWS: Altivec is called VMX in IBM land.

	* NEWS: Noted faster altivec support.

2006-01-07  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_cc_maxopt.m4: updated icc flag detection

2006-01-06  Matteo Frigo  <athena@fftw.org>

	* TODO: Note ``memoize triggen''.

	* mkdist.sh: Use --enable-threads to generate dependencies in the
	threads/ directory.

	* kernel/ifftw.h: Workaround to icc #defining __GNUC__.

	* configure.ac: Switched name to 3.1-beta1.

	* TODO: More thoughts.

	* TODO: Note wish that (block_size % 4) == 0.

	dft/simd/t.c, dft/simd/t1s.c, threads/ct.c, threads/hc2hc.c: Check
	alignment of mstart, mcount in SIMD codelets.

	* bootstrap.sh: Enable threads at bootstrap time, so I get the
	compiler warnings that I would otherwise ignore.

2006-01-05  Matteo Frigo  <athena@fftw.org>

	* threads/dft-vrank-geq1.c, threads/rdft-vrank-geq1.c,

	* kernel/planner.c: Commented the hash table lookup algorithm.

	* kernel/planner.c: Fixed infinite loop in hashtable
	lookup/insert.  Grrr...

	ct_desc_s, to make k7 asm code insensitive to -malign-double.  For
	consistency, changed struct hc2hc_desc_s in the same way.

	* kernel/planner.c: Wrong check for infeasible slvndx in imprt().

	* kernel/planner.c: Removed obsolete function
	invoke_solver_if_correct_kind().

	* kernel/primes.c: Faster implementation of safe_mulmod(),
	avoiding divisions altogether.  Works for 0 <= p <= INT_MAX.

	* api/mapflags.c: FFTW_ALLOW_LARGE_GENERIC must belong to
	flags->l, it cannot be overridden by fftw.

2005-12-24  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/primes.c: no more need for limits.h, add some explanatory
	comments

2005-12-23  Matteo Frigo  <athena@fftw.org>

	* dft/k7/k7.c: Paranoia.

	* kernel/ifftw.h, kernel/planner.c: Fixed subtle bug involving
	overflow of the slvndx field in flags_t.

	* NEWS: Note 64-bit clean.

	* threads/ct.c, threads/dft-vrank-geq1.c, threads/hc2hc.c,
	threads/rdft-vrank-geq1.c, threads/threads.h,
	threads/vrank-geq1-rdft2.c: Threads are now 64-bit clean

	* kernel/ifftw.h: Restored the old numbering TW_NEXT=3 etc,
	because the k7 code depends on it.

	* configure.ac, kernel/ifftw.h, kernel/primes.c: Portable
	implementation of MULMOD() and safe_mulmod().  Removed all
	unnecessary AC_CHECK_SIZEOF() from configure.ac.

2005-12-22  Matteo Frigo  <athena@fftw.org>

	* genfft/gen_r2r.ml: Inline the loop body in r2r codelets like we
	do everywhere else.

	* dft/conf.c: Oops.

	* dft/bluestein.c, dft/dftw-generic.c, dft/dftw-genericbuf.c,
	dft/rader.c, kernel/ifftw.h, kernel/trig.c, kernel/twiddle.c,

	kernel/ifftw.h, kernel/trig.c, kernel/trig1.c, kernel/twiddle.c,
	rdft/dht-rader.c: Somewhat faster generation of twiddle factors.

2005-12-21  Matteo Frigo  <athena@fftw.org>

	* kernel/md5.c: tweaks

	* dft/bluestein.c, dft/buffered.c, dft/ct.c, dft/ctsq.c,

	reodft/rodft00e-r2hc-pad.c, reodft/rodft00e-r2hc.c, tests/hook.c:
	Sped up planner, esp. in estimate mode.  The planner now
	classifies all solvers into DFT, RDFT, and RDFT2, and it only
	invokes solvers appropriate for the problem being planned.
	Because we have several hundred solvers, the overhead of calling
	irrelevant solvers is significant, and this modification mitigates
	the issue somewhat.

2005-12-20  Matteo Frigo  <athena@fftw.org>

	* kernel/print.c: Eliminated all calls to sprintf() in favor of
	own routines, so as not to force users to link stdio and the
	associated locale/pthreads crap.

	* kernel/ifftw.h, kernel/print.c: Implemented routine to print
	INT, removing the need for c99's %td format.

2005-12-19  Matteo Frigo  <athena@fftw.org>

	* kernel/alloc.c: info->n is size_t

2005-12-18  Matteo Frigo  <athena@fftw.org>

	* configure.ac, dft/problem.c, rdft/problem.c, rdft/problem2.c:
	Explicit casts in front of pointer difference in printf() context,
	just in case INT != ptrdiff_t.

2005-03-25  Matteo Frigo  <athena@fftw.org>

	* kernel/planner.c: Moved timeout check outside the search loop,
	because X(seconds) is expensive.

2005-03-20  Matteo Frigo  <athena@fftw.org>

	* dft/ct.c: Enable vector recursion for in-place problems,

	* dft/dftw-genericbuf.c: oops

	* dft/dftw-genericbuf.c: make solver UGLY for small N

	Added genfft flag -precompute-twiddles which moves the computation
	of the twiddle factors before the main schedule.  This flag
	produces smaller code everywhere, and slightly faster code on
	powerpc.  I observe no speed difference on x86.

2005-03-15  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/kalloc.c: sp

	* kernel/alloc.c: whoops, spelling error (thanks to Steve Eddins
	for bug report)

2005-03-12  Matteo Frigo  <athena@fftw.org>

	* dft/vrank-geq1.c, rdft/vrank-geq1-rdft2.c, rdft/vrank-geq1.c: Do

	guaranteed not to be a simple codelet.

2005-03-10  Matteo Frigo  <athena@fftw.org>

	* dft/direct.c: Relaxed applicability conditions.

2005-03-09  Matteo Frigo  <athena@fftw.org>

	* dft/dftw-generic.c: Minor optimization

	* libbench2/problem.c: Interpret <N>K to mean <N>*1024.  Similarly
	for <N>M.

	* kernel/primes.c: Hmm... somehow some previous commit got lost.

	* dft/ct.c: Paranoia

2005-03-07  Steven G. Johnson  <stevenj@fftw.org>

	* configure.ac: whoops

	* configure.ac, m4/ax_cc_maxopt.m4: move fftw-specific HP/UX tweak
	into configure.ac

	* configure.ac, m4/ax_cc_family.m4, m4/ax_cc_maxopt.m4,
	m4/ax_cc_vendor.m4: ax_cc_family -> ax_cc_vendor (vendor names are
	easier to remember), add checks for many new compilers, use in
	ax_cc_maxopt

2005-03-07  Matteo Frigo  <athena@fftw.org>

	* kernel/planner.c: Count FMA as one flop in estimator when
	HAVE_FMA

	* dft/dftw-generic.c: Do not try radix-2 generic.

2005-03-06  Matteo Frigo  <athena@fftw.org>

	* m4/ax_cc_maxopt.m4: Use -O3 for xlc now that we use -O for
	CODELET_OPTIM

	* configure.ac, m4/ax_cc_family.m4: New AX_CC_FAMILY macro, that
	detects the compiler based on symbols that it defines (as opposed
	to the name of the compiler).  We need to start use this strategy
	everywhere else.

	* dft/direct.c: Runtime checks to guarantee small strides.

	* dft/vrank-geq1.c, kernel/tensor7.c, rdft/rank0.c,
	rdft/vrank-geq1.c: Reduced the search space for rank-0 transforms

2005-03-04  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/primes.c: little assert

2005-03-01  Matteo Frigo  <athena@fftw.org>

	* dft/dft.h, dft/dftw-direct.c, dft/direct.c, dft/kdft.c:
	Implemented directbuf, enabled for now.

	* dft/Makefile.am, dft/dftw-direct.c, dft/dftw-directbuf.c,
	dft/kdft-dif.c, dft/kdft-dit.c: Unified dftw-direct,
	dftw-directbuf in an attempt to tame code growth

2005-02-27  Steven G. Johnson  <stevenj@fftw.org>

	* doc/fftw3.texi: fixed copyright

2005-02-27  Matteo Frigo  <athena@fftw.org>

	* rdft/rank0.c: silence warnings

	* rdft/rank0.c: oops

	* rdft/rank0.c: Tweaking while thinking about a higher-rank
	transposer (bitreverser)

	* dft/dftw-directbuf.c: Transposed the buffer, and skewed it.
	This allows for contiguous copy operations, and the codelet should
	not incur associativity conflicts if the buffer is large.

2005-02-26  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/tensor4.c: make tensor_max_index more reasonable (take
	maximum of input and output max indices, computed separately)

2005-02-26  Matteo Frigo  <athena@fftw.org>

	* rdft/vrank3-transpose.c: Use cpy2d instead of cpy2d_tiled,
	because vl may be too large.

	* genfft/annotate.ml: Fixed old bug that was introduced with
	yesterday's changes.

	* kernel/cpy1d.c: ``Interesting'' switch statement.

2005-02-25  Matteo Frigo  <athena@fftw.org>

	* support/Makefile.codelets: Disabled -reorder-loads
	-reorder-stores, since they seem to do nothing.

2005-02-25  Steven G. Johnson  <stevenj@fftw.org>

	* rdft/rank-geq2.c, dft/rank-geq2.c: Because of the recent changes
	to kernel/pickdim.c, splitrnk=0 is no longer equivalent to
	splitrnk=1 for rnk < 4, where the latter is the FFTW2 behavior.
	For small rnk, however, I observe the planner to pretty
	consistently choose the FFTW2 behavior (splitrnk=1), despite its
	not being asymptotically optimal in the cache oblivious sense.
	So, make splitrnk=1 instead of splitrnk=0 the default in
	FFTW_MEASURE and FFTW_ESTIMATE modes (rnk > 3 is pretty rare in
	practice anyway).

	* dft/indirect-transpose.c: tweak

	* dft/indirect-transpose.c: slight relaxation

	* dft/indirect-transpose.c: cruft

	* dft/Makefile.am, dft/conf.c, dft/dft.h,
	dft/indirect-transpose.c, dft/indirect.c, kernel/ifftw.h,
	kernel/tensor4.c: added experimental indirect-transpose solver:
	when transforming the columns of the matrix, allow us to do a
	transpose to make the DFTs contiguous

	* configure.ac: check for abort()

	* kernel/assert.c: call abort() on failed assertion

2005-02-25  Matteo Frigo  <athena@fftw.org>

	* kernel/primes.c: Forgot to change X(isqrt) -> isqrt_maybe

2005-02-25  Steven G. Johnson  <stevenj@fftw.org>

	* rdft/rank-geq2-rdft2.c, rdft/rank-geq2.c, dft/rank-geq2.c:
	require finite_rnk

2005-02-24  Matteo Frigo  <athena@fftw.org>

	* support/Makefile.codelets, support/twovers.sh,
	genfft/annotate.ml, genfft/magic.ml: Implemented reordering of
	loads and stores so that the real and imaginary part are
	loaded/stored together.  This should improve out-of-cache
	performance in the presence of associativity conflicts, and maybe
	worsen in-cache performance because of worse scheduling.  Enabled
	for now, for experimental purposes.

2005-02-24  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_gcc_aligns_stack.m4: fix comment

	* m4/ax_gcc_aligns_stack.m4: better message

	* m4/ax_gcc_aligns_stack.m4: use gcc version > 3.0 as fallback in
	check for alignment bug

	* m4/ax_gcc_aligns_stack.m4: don't use -malign-double
	unconditionally (it is only available on x86)

2005-02-24  Matteo Frigo  <athena@fftw.org>

	* kernel/transpose.c: Subtler selection of tilesz.

	* rdft/rank0.c: Call cpy2d_tiledbuf, not cpy2d_tiled.

	* kernel/cpy2d.c, kernel/transpose.c: buffer sizes were wrong :-(

	* kernel/cpy2d.c, kernel/ifftw.h, kernel/tile2d.c,
	kernel/transpose.c, rdft/rank0.c: Single function for computing
	tile size.  Eliminate spurious assertions.

	* kernel/tile2d.c: Do tiling recursively.

	* kernel/Makefile.am, kernel/cpy2d.c, kernel/ifftw.h,
	kernel/tile2d.c, kernel/transpose.c, rdft/rank0.c,
	rdft/vrank3-transpose.c: Reworked tiled transposes; provide tiling
	with and without buffering.  I can't believe that one has to waste
	his life with this @#$%.

	* kernel/pickdim.c: Clarified logic.  I am not sure why the code
	was so confusing to begin with.  The computation of *dp in the
	which_dim == 0 case was also wrong, returning e.g. *dp == -1 if
	sz->rnk == 1.

	* configure.ac: Enable aggressive inlining in codelets only, to
	avoid code bloat.

	* kernel/Makefile.am, kernel/cpy2d.c, kernel/ifftw.h,
	kernel/primes.c, kernel/transpose-rec.c, kernel/transpose.c,
	rdft/rank0.c, rdft/vrank3-transpose.c: Removed cache-oblivious
	copy/transpose algorithms in favor of explicitly blocked
	algorithms.  The cache-oblivious algorithms fail if there are
	associativity conflicts, in which case buffering is necessary, as
	per Carter and Gatlin.  Once you set the buffer size, there is no
	point whatsoever to do the algorithm recursively, and you may as
	well use blocking.

2005-02-23  Steven G. Johnson  <stevenj@fftw.org>

	* configure.ac: --disable-fortran now differs from
	--enable-fortran that fails

	* api/f77api.c: comment tweak

	* api/f77api.c: If a Fortran compiler was not detected, just make
	our best guess at what wrappers to use...I'm sick of dealing with
	user complaints from cases where wrapper detection fails for
	whatever reason.

	* api/f77funcs.h: fflush(stdout) after print_plan, in case F77
	doesn't

2005-02-23  Matteo Frigo  <athena@fftw.org>

	* mkdist.sh: --enable-sse is necessary after all, to generate all
	dependencies correctly.

	* dft/dftw-directbuf.c, kernel/Makefile.am, kernel/cpy2d-pair.c,
	kernel/ifftw.h: Put cpy2d_pair into its own file, so that I can
	experiment with buffering of nontwiddle codelets.

	* doc/Makefile.am: Copy rfftwnd.png from ${srcdir}, not $PWD

2005-02-22  Matteo Frigo  <athena@fftw.org>

	* rdft/rank0.c: Do not bother memcpy-ing complex numbers.

	* kernel/cpy2d.c, kernel/transpose-rec.c: Tighther layout of
	buffers.  I am not sure it matters, but just in case...

	* rdft/rank0.c: Usec cpy1d for rank-0 copies

	* kernel/Makefile.am, kernel/cpy1d.c, kernel/cpy2d.c,
	kernel/ifftw.h, kernel/transpose-rec.c, kernel/transpose.c,
	rdft/rank0.c, rdft/vrank3-transpose.c: Implemented in-place
	transposes with buffering.  Moved copy/transposition routines into
	own files, so that we can reuse them from multiple places.  TODO:
	merge vrank3-transpose.c with rank0.c, or rename
	vrank3-transpose.c to rank0-fancy.c or something like that; decide
	whether square in-place transposes should be in rank0.c or
	vrank3-transpose.c; apply FIXME's in vrank3-transpose.c.

	* kernel/print.c: Indentation should be printed after newline, not
	at the beginning of print()

2005-02-21  Matteo Frigo  <athena@fftw.org>

	* rdft/rank0.c: generalized in anticipation of more complicated
	solvers.

	* rdft/rank0.c: Implemented buffered recursive transpose

2005-02-20  Matteo Frigo  <athena@fftw.org>

	* rdft/rank0.c: Fixed comment

	* rdft/Makefile.am, rdft/conf.c, rdft/rank0-vrank2.c,
	rdft/rank0.c, rdft/rdft.h: grand unification of rank0 solvers

	* rdft/vrank3-transpose.c: manual tail-recursion optimization

2005-02-19  Matteo Frigo  <athena@fftw.org>

	* libbench2/verify-lib.c, libbench2/verify-r2r.c, tests/check.pl:
	implemented check for transpositions

	* libbench2/verify-lib.c: Previous fix was wrong for rdft2
	problems.

	* rdft/dft-r2hc.c: vecsz->rnk must be finite for this solver to
	apply.

	* rdft/vrank3-transpose.c: unified the various simple''
	transposers

	* libbench2/verify-lib.c, libbench2/verify-r2r.c,
	rdft/vrank3-transpose.c: Fixed stupid bug in rec_transpose_swap.
	Fixed stupid verifier that did not catch the bug.

	* rdft/vrank3-transpose.c: Minor cleanup of transposition
	routines.

	* dft/dftw-directbuf.c, rdft/hc2hc-directbuf.c: Make the batch
	size B=Theta(r) instead of B=Theta(1) in buffered twiddle solvers.
	Theory: for cache line size L, we want B = Omega(L) to utilize the
	cache line fully.  We also want B*r =O(Z), where Z is the size of
	the cache.  It is safe to assume that Z = Theta(L^2): cache
	designers will tend to make L as large as they can get away with,
	because they don't have to program the machines that they build,
	and Z < Theta(L^2) will screw up the little matrix transposition
	benchmarks that they use to design the cache.  Hence, B=Theta(r)
	is the right number.

2005-02-19  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_gcc_archflag.m4: for --enable-portable-binary, only try
	-mcpu=$arch and -m$arch on x86, since these generate non-portable
	code on every other target (and some other targets, like Alpha,
	don't support -mtune=$arch).

2005-02-18  Matteo Frigo  <athena@fftw.org>

	* kernel/ifftw.h: gcc/aix defines _POWER, not __powerpc__ like the
	rest of the world does.

2005-02-17  Matteo Frigo  <athena@fftw.org>

	* configure.ac: enable fma for ia64, since it seems to help with
	the hpux compiler.

	* TODO: *** empty log message ***

2005-02-16  Matteo Frigo  <athena@fftw.org>

	* simd/simd-altivec.h: Fixes for darwin

	* api/apiplan.c: Made the correctness of the code more obvious.

2005-02-16  Steven G. Johnson  <stevenj@fftw.org>

	* NEWS, m4/ax_cc_maxopt.m4:
	s/with-portable-binary/enable-portable-binary/ to be GNUlly
	correct; I'm sticking with --with-gcc-arch=arch, however, as
	--enable-gcc-arch=arch has the wrong connotations for me

	* api/apiplan.c: whoops

	* api/apiplan.c: bless wisdom with patience used to create it

	* api/apiplan.c: whoops

	* NEWS, TODO, api/apiplan.c, api/fftw3.h, doc/fftw3.texi,
	kernel/ifftw.h, kernel/planner.c, kernel/timer.c, tests/bench.c:
	added 'timed' planner option

2005-02-16  Matteo Frigo  <athena@fftw.org>

	* dft/simd/Makefile.am, simd/Makefile.am: Do not use SIMD_CFLAGS.
	The theory is that if taint.c is unsafe with SIMD_CFLAGS, then all
	files in this directory are as well.  Conversely, if these files
	require SIMD_CFLAGS because they include "simd.h", then taint.c
	requires SIMD_CFLAGS as well, and thus we need some other hack.

	* dft/codelets/standard/Makefile.am, dft/simd/Makefile.am,
	dft/simd/codelets/Makefile.am, rdft/codelets/hc2r/Makefile.am,
	rdft/codelets/r2hc/Makefile.am, rdft/codelets/r2r/Makefile.am,
	support/Makefile.codelets: Do not override CFLAGS in Makefile.am.

2005-02-15  Matteo Frigo  <athena@fftw.org>

	* configure.ac: Allow users to build long double version even if
	sizeof(long double) == sizeof(double)

	* commercialize.sh: Updated for 3.1

	* api/version.c: Oops, version.h is no longer used

2005-02-14  Matteo Frigo  <athena@fftw.org>

	* api/Makefile.am, api/version.c, configure.ac,

	rdft/codelets/r2hc/Makefile.am, rdft/codelets/r2r/Makefile.am,
	support/Makefile.am, support/Makefile.codelets,
	support/twovers.sh: unified fma and non-fma versions

	* configure.ac: forgot to remove inplace/Makefile from
	configure.ac

	* dft/codelet-dft.h, dft/codelets/Makefile.am,
	dft/codelets/inplace/Makefile.am,
	dft/codelets/standard/Makefile.am, dft/conf.c, Makefile.am: Merged
	dft/codelets/inplace with the main dft/codelets/standard
	directory.  This step makes dft codelets consistent with the rest
	of the naming conventions, and will simplify the eventual merge of
	fma and non-fma codelets.

	* simd/altivec.c, simd/simd-altivec.h: inline altivec constants,
	since gcc seems to generate better code this way.

2005-02-13  Matteo Frigo  <athena@fftw.org>

	* simd/altivec.c, simd/simd-altivec.h: group altivec constants
	into a single array, for faster access

	* genfft/c.ml, genfft/c.mli, genfft/simd.ml: code cleanup

	* genfft/c.ml, genfft/c.mli: removed some unused stuff

	* simd/simd-3dnow.h, simd/simd-altivec.h: New twiddle scheme for
	altivec, 3dnow

	* simd/simd-sse2.h: Implemented new twiddle scheme for sse2

	* dft/simd/Makefile.am, dft/simd/codelets/Makefile.am,
	dft/simd/q1b.h, dft/simd/q1f.h, dft/simd/t1b.h, dft/simd/t1f.h,
	dft/simd/t2b.h, dft/simd/t2f.h, simd/simd-sse.h: Implemented
	experimental t2* codelets, which store twiddle factors in a more
	convenient format, at the expense of twice the storage.  Currently
	only SSE works; I have to port SSE2, altivec, etc. to the new
	scheme.  After this, we will decide whether these codelets are
	worth the price.

2005-02-11  Matteo Frigo  <athena@fftw.org>

	* simd/simd-altivec.h: Forgot to define SIMD_STRIDE_OKPAIR

	* simd/simd-3dnow.h, simd/simd-altivec.h, simd/simd-sse.h,
	simd/simd-sse2.h: fixed sse2, 3dnow, and altivec, as promised

	* simd/simd-sse.h, dft/simd/n2b.c, dft/simd/n2f.c,
	genfft/annotate.ml, genfft/expr.ml, genfft/expr.mli,
	genfft/simd.ml: Generate n2?v_* codelets in such a way that we may
	or may not pair stores, depending on which mode happens to work
	best on a particular SIMD implementation.  sse2, 3dnow, and
	altivec are currently broken---will fix soon.

2005-02-10  Matteo Frigo  <athena@fftw.org>

	* simd/altivec.c, simd/simd-altivec.h: instantiate altivec
	constants only once

	* dft/simd/n2b.c, dft/simd/n2f.c: Fixed alignment checks for new
	SIMD scheme

	* dft/simd/codelets/Makefile.am, genfft/annotate.ml,
	genfft/annotate.mli, genfft/expr.ml, genfft/expr.mli,
	genfft/gen_notw_c.ml, genfft/genutil.ml, genfft/simd.ml,
	genfft/simdmagic.ml, simd/simd-3dnow.h, simd/simd-altivec.h,
	simd/simd-sse.h, simd/simd-sse2.h: Change n2?v_* codelets to store
	pairs of vectors, with implicit 2x2 transposition.  Works for
	2-way SIMD as well.  Tested with sse and sse2.  I haven't tried
	altivec yet, but I observed a huge speedup when I transformed one
	codelet by hand.

2005-02-09  Matteo Frigo  <athena@fftw.org>

	* dft/codelets/standard/Makefile.am: Resurrected old DIF codelets
	for experimental purposes.  They are disabled for now, but I am
	keeping the setup around for future reference.

2005-02-08  Matteo Frigo  <athena@fftw.org>

	* libbench2/bench-main.c: Silence warnings.

2005-02-08  Steven G. Johnson  <stevenj@fftw.org>

	* libbench2/getopt.h: when we compile our own getopt, change
	symbol names to avoid conflicts (e.g. avoid build failure on MacOS
	X with --enable-shared)

	* reodft/reodft00e-splitradix.c: grr, more bugfixes for in-place
	case

2005-02-08  Matteo Frigo  <athena@fftw.org>

	* dft/codelets/standard/Makefile.am: removed relics of FRANZ mode

2005-02-07  Matteo Frigo  <athena@fftw.org>

	* simd/altivec.c: Somehow xlc does not like ``vector int dummy;''

	* mkdist.sh: There is no need to enable sse to make the
	distribution.  This might have been true in the past but not
	anymore.

	* api/Makefile.am: Oops---included fortran file in C sources

	* api/Makefile.am, api/version.c: Set version string at ``make
	dist'' time, not at ``configure'' time, so we know whether a user
	is using the fma version or not.

2005-02-06  Matteo Frigo  <athena@fftw.org>

	* genfft/gen_hc2r_noinline.ml, genfft/gen_notw_noinline.ml,
	genfft/gen_notw_noinline_c.ml, genfft/gen_r2hc_noinline.ml:
	Removed useless files

	* configure.ac, dft/codelets/standard/Makefile.am,
	dft/simd/codelets/Makefile.am, genfft/Makefile.am, genfft/c.ml,
	genfft/c.mli, genfft/gen_hc2hc.ml, genfft/gen_hc2r.ml,
	genfft/gen_notw.ml, genfft/gen_notw_c.ml, genfft/gen_r2hc.ml,
	genfft/gen_twiddle.ml, genfft/gen_twiddle_c.ml,
	genfft/gen_twidsq.ml, genfft/gen_twidsq_c.ml, genfft/genutil.ml,
	genfft/simd.ml, kernel/ifftw.h, kernel/stride.c,
	rdft/codelets/hc2r/Makefile.am, rdft/codelets/r2hc/Makefile.am,
	support/Makefile.codelets: Different (simpler?) way to prevent the
	compiler from optimizing loop inductive variables.  We now
	explicitly corrupt stride variables by xor-ing them with another
	variable that happens to be zero (but the compiler does not know
	it).  In this way, the compiler does not attempt to extract a
	zillion loop indices from codelets, which would overflow the
	register set.  Set the -fno-loop-optimize flag to further help the
	process.

	Consequences: removed m* codelets.  Smaller library size.
	Slightly faster code with gcc/powerpc (including altivec).  Much
	faster code with xlc/powerpc.  No changes for gcc/pentium.  Maybe
	slightly faster with icc/pentium.

2005-02-05  Steven G. Johnson  <stevenj@fftw.org>

	* reodft/reodft00e-splitradix.c: paranoia about in-place rodft00
	plans

	* kernel/planner.c: don't believe pcost when using the
	estimator...there is no point, and it screws up estimator hacks to
	prefer in-codelet loops to vecloops

2005-02-05  Matteo Frigo  <athena@fftw.org>

	* m4/ax_cc_maxopt.m4: Reduced optimization level from -O3 to -O
	for xlc, since -O generates faster code.

2005-02-05  Steven G. Johnson  <stevenj@fftw.org>

	* reodft/reodft00e-splitradix.c: whoops, only applicable to
	redft00/rodft00 plans

	* reodft/reodft00e-splitradix.c: fixed in-place operation, and
	don't create size-0 sub-plans

2005-02-04  Matteo Frigo  <athena@fftw.org>

	* simd/altivec.c: Autodetect altivec on linux.  This code works
	with gcc-3.4 and -maltivec, with or without -mabi=altivec.  The
	code *should* work with gcc-3.3 without -mabi=altivec.  However,
	disabling -mabi=altivec on gcc-3.4 produces much worse code (I
	don't know why).

2005-01-28  Steven G. Johnson  <stevenj@fftw.org>

	* doc/fftw3.texi: update reference

2005-01-27  Steven G. Johnson  <stevenj@fftw.org>

	* doc/fftw3.texi: note that DCT-II/III are often called the''
	DCT/DCT

2005-01-21  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/cycle.h: added MSVC++ for ia64 (based on information at
	http://www.intel.com/cd/ids/developer/asmo-na/eng/19949.htm?prn=Y)

	* kernel/cycle.h: vc++ defines _M_AMD64 on x86-64, apparently

2005-01-19  Steven G. Johnson  <stevenj@fftw.org>

	* m4/acx_pthread.m4: avoid gratuitous breakage with -Werror,
	requested by Simon Perreault

2005-01-17  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_gcc_aligns_stack.m4: comment typo

2005-01-15  Steven G. Johnson  <stevenj@fftw.org>

	* configure.ac: bumped shared-lib revision#

	* api/fftw3.h, api/flops.c, kernel/ifftw.h, kernel/planner.c,
	tests/bench.c: add X(estimate_cost) to get estimator cost, and
	print from bench, to aid in tweaking estimator

	* doc/fftw3.texi: *** empty log message ***

	* doc/fftw3.texi: formatting fix

	* doc/fftw3.texi, reodft/Makefile.am, reodft/conf.c: tweaks

	* reodft/reodft00e-splitradix.c: use less buffer space

	* doc/fftw3.texi, reodft/Makefile.am, reodft/conf.c,
	reodft/redft00e-r2hc.c, reodft/reodft.h,
	reodft/reodft00e-splitradix.c, reodft/rodft00e-r2hc.c: added
	split-radix-based dct/dst I for odd n

	* api/fftw3.h: *** empty log message ***

	* api/fftw3.h: warn silly users who confuse CVS id with FFTW
	version

2005-01-14  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_gcc_archflag.m4: get sparc cpu type on solaris as well as
	with linux

	* m4/ax_gcc_archflag.m4: detect prescott mobile (f37)

2005-01-13  Steven G. Johnson  <stevenj@fftw.org>

	* bootstrap.sh, m4/ax_gcc_archflag.m4: use cpuid for x86_64 as
	well as i[56]86

	* m4/ax_gcc_archflag.m4: update with x86info 1.7 and other sources
	(identify k8, nocona, etc), handle nonzero leading bytes in eax

	* m4/acx_pthread.m4: compactified check for JOINABLE; use
	AC_DEFINE_UNQUOTED instead of AC_DEFINE for
	PTHREAD_CREATE_JOINABLE (thanks to Oliver Niekrenz for the bug
	report)

2005-01-12  Matteo Frigo  <athena@fftw.org>

	* genfft/annotate.ml: The scheduler hack was incorrect because it
	swapped instructions of the form A = *B and *B = C.  Fixed.

	* m4/ax_cc_maxopt.m4, m4/ax_gcc_archflag.m4: Quote expressions
	such as ``if test $FOO = yes'' when $FOO may be empty.  Also, $GCC
	is set to either ``yes'' or empty, never to ``no''.

	* TODO, configure.ac, simd/altivec.c: Hmm---somehow the previous
	commit did not work.

2005-01-11  Matteo Frigo  <athena@fftw.org>

	* simd/simd-altivec.h: Fixed various gcc-related problems on
	powerpc: - gcc-3.4 becomes totally confused by expressions like
	vec_add(a, vec_add(b, vec_add(c, ...)))  The compiler uses
	gigabytes of memory and then crashes, presumably because of the
	exponential-time search problem involved in typing the above
	expression (since vec_add can take either ints or floats).  I
	changed VADD and similar macros to be inline functions, thus
	constraining the type system.

	  - New flags --param inline-unit-growth=1000 --param
	      large-function-growth=1000 to work around limitations of the
	      gcc-3.4 inliner.

	* simd/simd-altivec.h: Check for HAVE_ALTIVEC_H

	* configure.ac, simd/altivec.c, simd/simd-altivec.h: Remove
	support for altivec using gcc builtins, since these keep changing
	across gcc versions.  These changes work on gcc-3.4/linux; I
	haven't tried MacOS X yet.  (The altivec ``spec'' differs between
	Motorola/Apple and gcc, grrr...)

2005-01-10  Matteo Frigo  <athena@fftw.org>

	* rdft/rank0-vrank2.c: Stylistic changes

	* rdft/dft-r2hc.c: Changed incorrect ugliness condition.

2005-01-10  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_gcc_archflag.m4: note x86info version number that was
	used, to make it easier to update the cpuid for changes in later
	versions

2005-01-10  Matteo Frigo  <athena@fftw.org>

	* rdft/dft-r2hc.c: Make dft-r2hc non-UGLY for rank-0 problems

	* m4/ax_gcc_archflag.m4: Do not use -mcpu=970 on power4
	processors, because power4 does not have altivec.

	* TODO: Note gcc-3.4 problem with inlining.

	* genfft/gen_hc2r_noinline.ml, genfft/gen_notw_noinline_c.ml:
	Oops, forgot to remove ``static'' from the declaration of
	noninlinable functions.

	* m4/ax_gcc_archflag.m4: Recognize power4.  Use ``head -n COUNT''
	instead of obsolete ``head -COUNT'' (which fails on gentoo).

	* TODO: Remind to add FAQ entry concerning gcc-3.4.[1-3] crashes.

2005-01-10  Steven G. Johnson  <stevenj@fftw.org>

	* m4/ax_gcc_version.m4: whoops

	* m4/ax_gcc_version.m4: support checking for
	major.minor.patchlevel

2005-01-10  Matteo Frigo  <athena@fftw.org>

	* configure.ac: Revert CODELET_OPTIM to -O on IA32, which is
	faster than -O2.

	* configure.ac: /bin/sh allows no spaces in assignments.

	* genfft/gen_hc2r_noinline.ml, genfft/gen_notw_noinline.ml,
	genfft/gen_notw_noinline_c.ml: Make non-inlinable functions
	external, so that gcc becomes confused and does not try to inline
	them.

2005-01-09  Matteo Frigo  <athena@fftw.org>

	* configure.ac: Add -fno-web to CFLAGS, because -fweb destroys
	FMAs.

	* m4/ax_gcc_archflag.m4: Allow -mcpu=970 besides -mcpu=G5

	* configure.ac: configure was not using -fno-schedule-insns :-(

	* kernel/planner.c: In mkplan() and elsewhere, use solver index
	instead of solver *pointer*, which looks marginally clearer.

	* TODO, kernel/ifftw.h, kernel/planner.c: Split planner hash table
	into two tables, for blessed and unblessed solutions respectively.
	Now an unblessed solution never overwrites a blessed solution,
	thus avoiding wisdom leakage by construction.  Further, forget()
	is now a O(1) operation, which speeds up the estimator when the
	wisdom table is large.

	* TODO: New TODO idea.

2005-01-06  Matteo Frigo  <athena@fftw.org>

	* kernel/planner.c: Split search() into two routines to make the
	UGLY/NO_UGLY logic obvious.

2004-12-17  Steven G. Johnson  <stevenj@fftw.org>

	* simd/3dnow.c, simd/sse.c, simd/sse2.c: push/pop 64-bit registers
	on ia64; thanks to Orion Poplawski for the fix

2004-12-10  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/kalloc.c: patch from FreeBSD ports - FreeBSD does not
	have memalign, but its malloc is 16-byte aligned

2004-11-23  Steven G. Johnson  <stevenj@fftw.org>

	* simd/Makefile.am: don't compile taint.c with SIMD_CFLAGS (fixed
	Debian bug #259612)

2004-11-18  Steven G. Johnson  <stevenj@fftw.org>

	* support/Makefile.codelets: revert incorrect change -- codlist.c
	should be rebuilt, but it is built in the build directory and not
	in the source directory

	* support/Makefile.codelets: $(CODLIST) should be rebuilt only if
	Makefile.am changes, or alternatively only in maintainer mode, to
	prevent stomping in the source directory during user builds.
	(Thanks to Grant Cook for the bug report.)

2004-11-13  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/cycle.h: corrected #ifdef for icc/ia64, thanks to Matt
	Boman

	* NEWS: spelling correction (Larsen, not Larson)

2004-11-08  Steven G. Johnson  <stevenj@fftw.org>

	* configure.ac, m4/ax_cc_maxopt.m4, m4/ax_openmp.m4: separate

	* m4/ax_gcc_archflag.m4: tweak

	* m4/ax_gcc_x86_cpuid.m4: comment

	m4/ax_gcc_version.m4, m4/ax_gcc_x86_cpuid.m4, m4/ocaml.m4: clean
	up m4 macros; try to detect correct gcc -march flag on x86; new
	--with-portable-binary, --with-gcc-arch=<arch> flags; use -O2 for
	codelets with gcc 3.4 to work around bug

2004-10-26  Steven G. Johnson  <stevenj@fftw.org>

	* libbench2/mp.c: rename cexp -> mcexp to avoid conflict with C99
	builtin

2004-10-25  Steven G. Johnson  <stevenj@fftw.org>

	* acinclude.m4: use basename , w/o args, for compiler-name
	comparisons; also detect Compaq ccc on alpha-linus

	* doc/FAQ/fftw-faq.bfnn: note recent icc problems

2004-10-24  Steven G. Johnson  <stevenj@fftw.org>

	* threads/threads.c: whoops, disable semaphores again (for now)

2004-04-07  Steven G. Johnson  <stevenj@fftw.org>

	* rdft/rank0-vrank2.c: whoops, extra alignment check

	* kernel/ifftw.h, rdft/rank0-vrank2.c, rdft/vrank3-transpose.c:
	disable most 2-float-as-double copying, add alignment check in one

	* kernel/transpose.c, kernel/tensor7.c: whoops

2004-03-31  Steven G. Johnson  <stevenj@fftw.org>

	* dft/dftw-generic.c, dft/vrank2-transpose.c,

2004-03-22  Matteo Frigo  <athena@fftw.org>

	* kernel/twiddle.c: Relax equality of twiddle description, since
	the `i' field is not used by TW_FULL or TW_HALF.

	* dft/dftw-generic.c, kernel/twiddle.c: Do not allocate tw_instr's

	The old solver was not applicable for out-of-place problems unless
	DESTROY_INPUT.  This is bogus.  As long as the subsolvers honor
	!DESTROY_INPUT, the solver is always applicable.

	Changed semantics of test program, so that PRESERVE_INPUT is
	always true unless the problem specifies destroy_input explicitly.
	Without this change, there is no way to test the new solver.

	* genfft/annotate.ml: New scheduling pass that keeps ``x = a + b''
	and ``y = a - b'' close together.  This property was no longer
	automatic for the dags generated in SIMD mode.

	I cannot measure any speed difference due to this change.
	However, the change is justified by a minimal-screwup argument.
	Moreover, the sse2 fftw library is now 1% smaller than it was

2003-07-03  Matteo Frigo  <athena@fftw.org>

	* genfft/magic.ml, genfft/schedule.ml: New experimental scheduler
	(currently disabled).

	The old scheduler is ``optimal'' in the sense that it minimizes
	register pressure.  The only way to reduce register pressure is to
	schedule dependent instructions as closely as possible, so as to
	minimize the life time of registers.  This strategy maximizes the
	number of pipeline stalls, however.  With enough registers and
	short enough pipelines, this tradeoff is fine.  This is no longer
	the case for the devilish pipeline of the Pentium IV or (probably)
	the PowerPC 970.

	The new scheduler switches to a ``list scheduler'' for dags
	smaller than a specified size.  The list scheduler executes a
	butterfly left to right one column at the time.  This amounts to
	the best possible pipeline utilization, and the worst possible
	register pressure.

	The ``specified size'' defaults to 0, i.e., no change from fftw2
	and fftw-3.0.  It seems like a value of 7--10 produces the best
	results for Pentium IV (probably screwing the G3/G4 powerpcs and
	sparc, but I haven't tried.)  As time goes by, we may want to
	increase this number to favor newer processors over older
	processors.

2003-06-25  Steven G. Johnson  <stevenj@fftw.org>

2003-02-07  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/planner.c: Added appropriate warning against likely
	future bug.

	* kernel/planner.c: Don't attempt to remove bogus wisdom entries.

2003-01-28  Matteo Frigo  <athena@fftw.org>

	* kernel/planner.c: Fixed a couple of very very very nasty
	bugs---pointers became invalid after the hash table was relocated.

	* tests/bench.c: Read wisdom at can_do() time, otherwise wisdom is
	destroyed.

	* kernel/planner.c: More conservative inheritance of blessings

	* dft/problem.c: Print the same info as it is hashed

2003-01-27  Matteo Frigo  <athena@fftw.org>

	* kernel/ifftw.h, kernel/planner.c: New NO_SEARCH planner flag,
	which avoids searching altogether.  A wisdom entry must lead to a
	NO_SEARCH-grade plan, or else the wisdom entry is bogus.

	* libbench2/verify-lib.c: Use cosl()/sinl() when appropriate

2003-01-26  Matteo Frigo  <athena@fftw.org>

	* kernel/planner.c, libbench2/problem.c, libbench2/speed.c,
	libbench2/verify.c: Use null pointers when estimating.  The
	estimator should never time anything.

2003-01-26  Steven G. Johnson  <stevenj@fftw.org>

	* api/f77api.c: note

	* api/Makefile.am, api/f77api.c, api/f77funcs.c, configure.ac:
	support multiple mangling schemes with g77

	* tests/check.pl: fixed verbose, made random tests only use
	selected rank, use rank <= 4, fixed final flush_problems call

	* tests/check.pl: fixed typo (count instead of maxcount)

	* configure.ac: hypot is no longer used

	* configure.ac, kernel/ifftw.h: check for _alloca (MSVC)

	* kernel/alloc.c: slight fix in assert

2003-01-26  Matteo Frigo  <athena@fftw.org>

	* libbench2/problem.c, libbench2/speed.c, libbench2/verify.c,
	tests/bench.c: Allocate problem in all cases--- can_do may need
	correct pointers.

	* tests/bench.c, tests/check.pl: Nastier checks

	* kernel/ifftw.h, kernel/plan.c, kernel/planner.c: X(use_plan) is
	a relic.

	* tests/Makefile.am: Print full pathname of the bench executable,
	so that I don't get confused when running multiple tests for
	different configurations.

	* libbench2/bench-main.c, libbench2/bench-user.h, tests/bench.c:
	Split done() into done() and cleanup(), in order to test multiple
	problems with the same planner from the command line.

	* kernel/alloc.c: Improved readability

2003-01-26  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/alloc.c: comment

	* kernel/alloc.c: added macos9 mpallocatealigned function

2003-01-25  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/alloc.c: sometimes __APPLE__ is defined instead of
	__MACOSX__

	* kernel/alloc.c: macos x malloc is already 16-byte aligned

2003-01-25  Matteo Frigo  <athena@fftw.org>

	* kernel/ifftw.h: Include <sys/types.h> because uintptr_t is
	defined there on solaris.

	* libbench2/Makefile.am, libbench2/getopt1.c: Oops---forgot
	getopt_long

	* configure.ac: Include default includes when checking for
	uintptr_t.  (Otherwise solaris breaks.)

	* tests/Makefile.am: distribute check.pl

	* tests/check.pl: Check split format, too.

	* tests/Makefile.am, tests/check.pl: New tests, added make check

2003-01-23  Matteo Frigo  <athena@fftw.org>

	* tests/check.pl: More tests

2003-01-22  Matteo Frigo  <athena@fftw.org>

	* libbench2/problem.c, api/mktensor-iodims.c,
	api/mktensor-rowmajor.c: Deal with rnk(sz)=-infinity

2003-01-21  Matteo Frigo  <athena@fftw.org>

	* TODO: Crazy idea

	* tests/check.pl: Test program, still barely worthy of the name.

2003-01-20  Matteo Frigo  <athena@fftw.org>

	* libbench2/problem.c: Stylistic changes

	* api/Makefile.am, api/fftw3.h, api/flops.c, tests/bench.c:
	Implemented flops api

2003-01-19  Steven G. Johnson  <stevenj@fftw.org>

	* libbench2/problem.c: cleanup

	* libbench2/problem.c: 'v' syntax now defaults to an 'internal'
	(stride 1) vector, which is a more interesting case and
	corresponds more closely to the intuitive notion of a 'vector'
	transform, while '*' does the old 'external' (stride n) vector

	* libbench2/problem.c: removed '/' overloading

	* libbench2/problem.c: get rid of '*' and ',' synonyms for 'x' in
	problem parser; there's no need to clutter the namespace with
	syntax we never use

2003-01-19  Matteo Frigo  <athena@fftw.org>

	* kernel/planner.c: Signed/unsigned fixes.

	* libbench2/bench-user.h, libbench2/verify-dft.c,
	libbench2/verify.c, libbench2/verify.h, tests/bench.c,
	tests/hook.c: Test split arrays.

	does not destroy arrays

2003-01-19  Matteo Frigo  <athena@fftw.org>

	* tests/bench.c: Clearer name

	libbench2/verify-dft.c, libbench2/verify-lib.c,

	not a problem flag

	* kernel/ifftw.h, kernel/planner.c: Maintain flags in canonical

	* kernel/ifftw.h, kernel/planner.c: In dramatic break with
	tradition, SUBSUME is now a partial order.  I swear.

	* kernel/planner.c: Added comment

	* kernel/ifftw.h, kernel/planner.c, tests/bench.c: Inverted
	ESTIMATE flag, renamed USE_SCORE for consistency with the

2002-09-17  Steven G. Johnson  <stevenj@fftw.org>

	* dft/indirect.c, kernel/ifftw.h, rdft/indirect.c, tests/bench.c:

2002-09-17  Matteo Frigo  <athena@fftw.org>

	* kernel/ifftw.h, kernel/planner.c: Yet another attempt at getting
	the planner right.

	* kernel/planner.c: Better coding.

	* kernel/ifftw.h, kernel/planner.c: NO_UGLY is no longer a flag,

2002-09-16  Steven G. Johnson  <stevenj@fftw.org>

	vs. ESTIMATE... ESTIMATE | IMPATIENT is a UI issue

	there's no reason we would want this flag to block plan reuse

	* kernel/ifftw.h: whoops, commas

	* kernel/ifftw.h: problem_flags == checked in applicable,
	planner_flags == checked in score

2002-09-14  Steven G. Johnson  <stevenj@fftw.org>

	* kernel/planner.c: string.h is used for more than strlen

2002-09-14  Matteo Frigo  <athena@fftw.org>

	* kernel/ifftw.h, kernel/planner.c: Reduced hashtable size by 1/6
	(on 32-bit machines) at the expense of messier planner.

	* tests/bench.c: Only print wisdom if verbose > 3

	* genfft-k7/variable.ml, genfft/variable.ml: Changed syntax of

2002-09-14  Steven G. Johnson  <stevenj@fftw.org>

2002-09-14  Matteo Frigo  <athena@fftw.org>

	* kernel/twiddle.c: Explicit cast

	* kernel/ifftw.h, kernel/planner.c, kernel/primes.c: Use

2002-08-26  Matteo Frigo  <athena@fftw.org>

	addressing in transpose routines.  (Seems to be slightly better on
	athlon.)

2002-08-26  Steven G. Johnson  <stevenj@fftw.org>

	* reodft/redft00e-r2hc.c, reodft/reodft11e-r2hc.c,

	dft/vrank-geq1.c, kernel/ifftw.h, rdft/vrank-geq1-rdft2.c,
	rdft/vrank-geq1.c: I had to add another planner flag to record
	whether pointers could become unaligned because of vrank-geq1
	solvers (these solvers only plan the first element of a vector
	problem, but the second element may have a different alignment).
	This addition is ugly, but I don't see any way around it.
