%changelog
* Sat Apr 19 2014 mardnh@gmx.de
- add support for long-double precision
* Sat Apr 19 2014 mardnh@gmx.de
- update to version 3.3.4
  * New functions fftw_alignment_of (to check whether two arrays are equally
    aligned for the purposes of applying a plan) and fftw_sprint_plan
    (to output a description of plan to a string).
  * Bugfix in fftw-wisdom-to-conf; thanks to Florian Oppermann for the bug report.
  * Fixed manual to work with texinfo-5.
  * Increased timing interval on x86_64 to reduce timing errors.
  * Default to Win32 threads, not pthreads, if both are present.
  * Various build-script fixes.
- Drop obsoleted 1_man_macro.patch
* Sun Dec 16 2012 dhall@wustl.edu
- update to version 3.3.3
  * Fix deadlock bug in MPI transforms (thanks to Michael Pippig for the bug
    report and patch, and to Graham Dennis for the bug report).
  * Use 128-bit ARM NEON instructions instead of 64-bit instructions. This
    change appears to speed up even ARM processors with a 64-bit NEON pipe.
  * Speed improvements for single-precision AVX.
  * Speed up planner on machines without "official" cycle counters, such as ARM.
* Tue Jul  3 2012 coolo@suse.com
- update to 3.3.2 to fix crashes with gcc 4.7
  * Removed an archaic stack-alignment hack that was failing with
    gcc-4.7/i386.
  * Added stack-alignment hack necessary for gcc on Windows/i386.  We
    will regret this in ten years (see previous change).
  * Fix incompatibility with Intel icc which pretends to be gcc
    but does not support quad precision.
  * make libfftw{threads,mpi} depend upon libfftw when using libtool;
    this is consistent with most other libraries and simplifies the life
    of various distributors of GNU/Linux.
* Tue May 29 2012 tiwai@suse.de
- Enable AVX support (bnc#763657)
* Thu Apr 26 2012 adrian@suse.de
- fix build on %%arm
  * disable neon it would require --enable-single (precision)
- enable openmpi for %%arm
* Fri Mar 16 2012 alinm.elena@gmail.com
- source the mpi environment
* Tue Mar  6 2012 dhall@wustl.edu
- delete INSTALL file
* Tue Mar  6 2012 dhall@wustl.edu
- patch macros in man files
* Tue Mar  6 2012 dhall@wustl.edu
- add use of neon extensions on ARM
* Tue Mar  6 2012 dhall@wustl.edu
- updated to version 3.3.1
  * Reduced planning time in estimate mode for sizes with large prime factors.
  * Added AVX autodetection under Visual Studio. Thanks Carsten Steger for submitting
    the necessary code.
  * Modern Fortran interface now uses a separate fftw3l.f03 interface file for the
    long double interface, which is not supported by some Fortran compilers. Provided
    new fftw3q.f03 interface file to access the quadruple-precision FFTW routines
    with recent versions of gcc/gfortran.
  * Added support for the NEON extensions to the ARM ISA.
  * MPI code now compiles even if mpicc is a C++ compiler; thanks to Kyle Spyksma for
    the bug report.
* Mon Nov 28 2011 idoenmez@suse.de
- Ignore rpmlint fixed dependency errors
* Mon Nov 28 2011 ro@suse.de
- fix build on s390/s390x without openmpi
* Mon Nov 21 2011 jengelh@medozas.de
- Remove redundant/unwanted tags/section (cf. specfile guidelines)
- Employ shlib naming (fftw3 -> libfftw3)
* Sun Oct  9 2011 adrian@suse.de
- enable sse only on supported architectures
* Wed Sep 28 2011 dhall@wustl.edu
- enable sse2 and sse code generation
* Fri Aug  5 2011 dhall@wustl.edu
- specfile cleanup
  * Remove authors from description
  * use %%makeinstall
- fix devel and mpi-devel to include proper header files
* Wed Aug  3 2011 dhall@wustl.edu
- updated to version 3.3:
  * Compiling OpenMP support (--enable-openmp) now installs a fftw3_omp
    library, instead of fftw3_threads, so that OpenMP and POSIX threads
    (--enable-threads) libraries can be built and installed at the same time.
  * Add support for the AVX extensions to x86 and x86-64
  * Added Fortran 2003 interface
  * Added MPI distributed-memory transforms
  * Add support for quad-precision __float128 in gcc 4.6 or later (on x86.
    x86-64, and Itanium). The new routines use the fftwq_ prefix.
  * New convenience functions fftw_alloc_real and fftw_alloc_complex to use
    fftw_malloc for real and complex arrays without typecasts or sizeof.
  * New convenience functions fftw_export_wisdom_to_filename and
    fftw_import_wisdom_from_filename that export/import wisdom to a file, which
    don't require you to open/close the file yourself.
  * New function fftw_cost to return FFTW's internal cost metric for a given plan
  * Remove --enable-portable-binary flag: we new produce portable binaries by default.
  * Fixed build problem failure when srand48 declaration is missing
  * Fixed bug in fftw_set_timelimit: ensure that a negative timelimit is equivalent
    to no timelimit in all cases
  * Fixed stack-overflow problem on OpenBSD caused by using alloca with too
    large a buffer.
