Mon Aug  1 22:03:49 UTC 2016 - mardnh@gmx.de

- update to version 3.3.5
  * New SIMD support:
    - Power8 VSX instructions in single and double precision.
      To use, add --enable-vsx to configure.
    - Support for AVX2 (256-bit FMA instructions).
      To use, add --enable-avx2 to configure.
    - Experimental support for AVX512 and KCVI. (--enable-avx512, --enable-kcvi)
      This code is expected to work but the FFTW maintainers do not have
      hardware to test it.
    - Support for AVX128/FMA (for some AMD machines) (--enable-avx128-fma)
    - Double precision Neon SIMD for aarch64.
      This code is expected to work but the FFTW maintainers do not have
      hardware to test it.
    - generic SIMD support using gcc vector intrinsics
  * Add fftw_make_planner_thread_safe() API    
  * fix #18 (disable float128 for CUDACC)
  * fix #19: missing Fortran interface for fftwq_alloc_real
  * fix #21 (don't use float128 on Portland compilers, which pretend to be gcc)
  * fix: Avoid segfaults due to double free in MPI transpose

-------------------------------------------------------------------
Sat Apr 19 19:16:23 UTC 2014 - mardnh@gmx.de

- add support for long-double precision

-------------------------------------------------------------------
Sat Apr 19 17:37:38 UTC 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 19:26:48 UTC 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.

- 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 14:43:58 CEST 2012 - tiwai@suse.de

- Enable AVX support (bnc#763657)

Tue Mar  6 00:12:32 UTC 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.

Wed Aug  3 13:58:49 UTC 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.
