* Correct bug in configure script: --enable-portable-binary option was ignored!
* Threads compilation fix on AIX: prefer xlc_r to cc_r, and don't use
either if we are using gcc.
* Updated FAQ to note that Apple gcc 4.0.1 on MacOS/Intel is broken,
and suggest a workaround. configure script now detects Core/Duo arch.
* Use -maltivec when checking for altivec.h.
* Performance improvements for Intel EMT64.
* Performance improvements for large-size transforms with SIMD.
* Cycle counter support for Intel icc and Visual C++ on x86-64.
* In fftw-wisdom tool, replaced obsolete --impatient with --measure.
* Fixed compilation failure with AIX/xlc; thanks to Joseph Thomas.
* Windows DLL support for Fortran API (added missing __declspec(dllexport)).
* SSE/SSE2 code works properly (i.e. disables itself) on older 386 and 486
CPUs lacking a CPUID instruction; thanks to Eric Korpela.
* Faster FFTW_ESTIMATE planner.
* New (faster) algorithm for REDFT00/RODFT00 (type-I DCT/DST) of odd size.
* "4-step" algorithm for faster FFTs of very large sizes (> 2^18).
* Faster in-place real-data DFTs (for R2HC and HC2R r2r formats).
* Faster in-place non-square transpositions (FFTW uses these internally
for in-place FFTs, and you can also perform them explicitly using
the guru interface).
* Faster prime-size DFTs: implemented Bluestein's algorithm, as well
as a zero-padded Rader variant to limit recursive use of Rader's algorithm.
* SIMD support for split complex arrays.
* Much faster Altivec/VMX performance.
* New fftw_set_timelimit function to specify a (rough) upper bound to the
planning time (does not affect ESTIMATE mode).
* Removed --enable-3dnow support; use --enable-k7 instead.
* FMA (fused multiply-add) version is now included in "standard" FFTW,
and is enabled with --enable-fma (the default on PowerPC and Itanium).
* Automatic detection of native architecture flag for gcc. New
configure options: --enable-portable-binary and --with-gcc-arch=<arch>,
for people distributing compiled binaries of FFTW (see manual).
* Automatic detection of Altivec under Linux with gcc 3.4 (so that
same binary should work on both Altivec and non-Altivec PowerPCs).
* Compiler-specific tweaks/flags/workarounds for gcc 3.4, xlc, HP/UX,
Solaris/Intel.
* Various documentation clarifications.
* 64-bit clean. (Fixes a bug affecting the split guru planner on
64-bit machines, reported by David Necas.)
* Fixed Debian bug no.259612: inadvertent use of SSE instructions on
non-SSE machines (causing a crash) for --enable-sse binaries.
* Fixed bug that caused HC2R transforms to destroy the input in
certain cases, even if the user specified FFTW_PRESERVE_INPUT.
* Fixed bug where wisdom would be lost under rare circumstances,
causing excessive planning time.
* FAQ notes bug in gcc-3.4.[1-3] that causes FFTW to crash with SSE/SSE2.
* Fixed accidentally exported symbol that prohibited simultaneous
linking to double/single multithreaded FFTW (thanks to Alessio Massaro).
* Support Win32 threads under MinGW (thanks to Alessio Massaro).
framework. The list of changes include:
* Modify compiler.mk so that "c" is always prepended to USE_LANGUAGES,
so we no longer need to say it in package Makefiles. Packages
should now append to USE_LANGUAGES instead of setting it.
* Create mk/compiler/f2c.mk which implements another pseudo-compiler
"f2c" that may be used with any C compiler backend, e.g.
PKGSRC_COMPILER= f2c ccache gcc
* Teach the various "real" compiler files, e.g., sunpro.mk, mipspro.mk,
etc., to use f2c if the native Fortran compiler isn't present.
Packages that use Fortran should now simply include the line:
USE_LANGUAGES+= fortran
in the package Makefile.
in the process. (More information on tech-pkg.)
Bump PKGREVISION and BUILDLINK_DEPENDS of all packages using libtool and
installing .la files.
Bump PKGREVISION (only) of all packages depending directly on the above
via a buildlink3 include.
* Some speed improvements in SIMD code.
* --without-cycle-counter option is removed. If no cycle counter is found,
then the estimator is always used. A --with-slow-timer option is provided
to force the use of lower-resolution timers.
* Added missing static keyword that prevented simultaneous linkage
of different-precision versions; thanks to Rasmus Larson for the bug report.
* Corrected accidental omission of f77_wisdom.f file; thanks to Alan Watson.
* Removed non-portable use of 'tempfile' in fftw-wisdom-to-conf script;
thanks to Nicolas Decoster for the patch.
* Added 'make smallcheck' target in tests/ directory, at the request of
James Treacy.
Major goals of this release:
* Speed: often 20% or more faster than FFTW 2.x, even without SIMD (see below).
* Complete rewrite, to make it easier to add new algorithms and transforms.
* New API, to support more general semantics.
Other enhancements:
* SIMD acceleration on supporting CPUs (SSE, SSE2, 3DNow!, and AltiVec).
(With special thanks to Franz Franchetti for many experimental prototypes
and to Stefan Kral for the vectorizing generator from fftwgel.)
* True in-place 1d transforms of large sizes (as well as compressed
twiddle tables for additional memory/cache savings).
* More arbitrary placement of real & imaginary data, e.g. including
interleaved (as in FFTW 2.x) as well as separate real/imag arrays.
* Efficient prime-size transforms of real data.
* Multidimensional transforms can operate on a subset of a larger matrix,
and/or transform selected dimensions of a multidimensional array.
* By popular demand, simultaneous linking to double precision (fftw),
single precision (fftwf), and long-double precision (fftwl) versions
of FFTW is now supported.
* Cycle counters (on all modern CPUs) are exploited to speed planning.
* Efficient transforms of real even/odd arrays, a.k.a. discrete
cosine/sine transforms (types I-IV). (Currently work via pre/post
processing of real transforms, ala FFTPACK, so are not optimal.)
* DHTs (Discrete Hartley Transforms), again via post-processing
of real transforms (and thus suboptimal, for now).
* Support for linking to just those parts of FFTW that you need,
greatly reducing the size of statically linked programs when
only a limited set of transform sizes/types are required.
* Canonical global wisdom file (/etc/fftw/wisdom) on Unix, along
with a command-line tool (fftw-wisdom) to generate/update it.
* Fortran API can be used with both g77 and non-g77 compilers
simultaneously.
* Multi-threaded version has optional OpenMP support.
* Authors' good looks have greatly improved with age.
