* BUG, BLD: Generate the main dispatcher config header into the build dirSayed Adel2021-01-032-11/+29
| | | | | | | | | | The new path becomes `build/src.*/numpy/distutils/include/npy_cpu_dispatch_config.h` instead of `numpy/core/src/common/_cpu_dispatch.h`. The new path allows other projects to re-use the CPU dispatcher once we decide to expose the following headers: - `numpy/core/src/common/npy_cpu_dispatch.h` - `numpy/core/src/common/npy_cpu_features.h`
* MAINT: regex char class improveTyler Reddy2020-12-281-4/+4
| | | | | | | | | | | | | * replace superfluous single-character regex character classes with their literal string equivalents; this avoids the overhead associated with a character class when there's only a single character enclosed (so there's no benefit to the class overhead) * for more information see: Chapter 6 of: Friedl, Jeffrey. Mastering Regular Expressions. 3rd ed., O’Reilly Media, 2009.
* MAINT, TST: Serveral imporvments to _SIMD moduleSayed Adel2020-10-271-1/+1
| | | | | | | | | | | | | | | | | | - use plain variables - clean up aligned allocate - use `PyArg_ParseTuple` for empty args - use `Py_ssize_t` instead of `unsigned` and `size_t` - improve coding style - no need for a custom raises assertions - use parametrize instead of inner loops - leave a comment about nature of mode testing unit - shift to get max/min of int72 - add more info to repr of vector object - get ride of exec() and use type() instead - use `.inc` as extension for sub-headers instead of `.h` - add `FMA4` and drop `SSE41` from _SIMD targets Co-authored-by: Eric Wieser <wieser.eric@gmail.com>
* ENH: Expose the NumPy C SIMD vectorization interface "NPYV" to PythonSayed Adel2020-10-272-2/+18
| | | | | | | | | | | | | | | | '_simd' is a new module to bring the NumPy C SIMD vectorization interface "NPYV" The module is designed to be extremely flexible so that it can accommodate any kind intrinsics, also to generate a python interface almost similar to the C interface. The main purpose of this module is to test NPYV intrinsics in python, but still can be used as an effective solution in designing SIMD kernels. Also add a new command-line argument `--simd-test` to control of targeted CPU features for the `_simd` module.

* ENH: [3/7] enable multi-platform SIMD compiler optimizationsSayed Adel2020-06-153-5/+131
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Put `CCompilerOpt` in action through add two command line arguments that passed directly to `CCompilerOpt`'s parameters which explained as follows: * `--cpu-baseline` minimal set of required optimizations, default is 'min' which provides the minimum CPU features that can safely run on a wide range of users platforms. * `--cpu-dispatch` dispatched set of additional optimizations, default is 'max-xop-fma4' which enables all CPU features, except for AMD legacy features. the new arguments can be reached from `build`, `build_clib`, `build_ext`, if `build_clib` or `build_ext` are not specified by the user the arguments of `build` will be used, which also hold the default values. - Activate the new compiler dispatcher that comes with `CCompilerOpt`, through adding a hock inside `build_clib` and `build_ext` that works as a filter taking any C source files ends with `.dispatch.c` and pass it directly to `CCompilerOpt` and then take returned objects and linked to the final C lib. - Add a third command-line argument `--disable-optimization` which explicitly disable the whole new infrastructure, also It adds a new compiler definition called `NPY_DISABLE_OPTIMIZATION`. when `--disable-optimization` is enabled the dispatch-able sources that end with `.dispatch.c` will be treated as a normal C sources, also due to this disabling any C headers that generated by `CCompilerOpt` must guard it with `NPY_DISABLE_OPTIMIZATION`, otherwise, it will definitely break the build. - New auto-generated C header located at `core/include/numpy/_cpu_dispatch.h`, the new header contains all definitions and headers of CPU features that enabled according to specified configuration in `--cpu-baseline` and `--cpu-dispatch`.
* BLD: Avoid "visibility attribute not supported" warning (gh-16288)E. M. Bray2020-05-201-1/+4
| | | | | | | | | | | | I found that when building the latest master branch on Cygwin, while testing #16246, that thousands of warnings were generated at build time like: numpy/core/src/npysort/binsearch.c.src: In function ‘binsearch_left_bool’: numpy/core/src/npysort/binsearch.c.src:82:1: warning: visibility attribute not supported in this configuration; ignored [-Wattributes] Granted this is just a warning, so I don't think it's a serious issue. It seems the test that was supposed to check for __attribute__ support was not working as expected. The #pragmas only take effect if I provide a function body--they are ignored for bare declarations. I don't know if that's by intent, or if it's a GCC issue. For reference: $ gcc --version gcc (GCC) 7.4.0

* | MAINT: Remove implicit inheritance from object class (#15236)Jon Dufresne2020-01-051-1/+1
| | | | | | | | | | | | | | Inheriting from object was necessary for Python 2 compatibility to use new-style classes. In Python 3, this is unnecessary as there are no old-style classes. Dropping the object is more idiomatic Python.

* distutils: handle unlinkable object files in build_clib/build_ext, not gnuPauli Virtanen2017-09-022-26/+86
| | | | | | | | | | | | | | | | | | | | | | Add concept of unlinkable Fortran object files on the level of build_clib/build_ext. Make build_clib generate fake static libs when unlinkable object files are present, postponing the actual linkage to build_ext. This enables MSVC+gfortran DLL chaining to only involve those DLLs that are actually necessary for each .pyd file, rather than linking everything in to every file. Linking everything to everywhere has issues due to potential symbol clashes and the fact that library build order is unspecified. Record shared_libs on disk instead of in system_info. This is necessary for partial builds -- it is not guaranteed the compiler is actually called for all of the DLL files. Remove magic from openblas msvc detection. That this worked previously relied on the side effect that the generated openblas DLL would be added to shared_libs, and then being linked to all generated outputs.
* distutils: gnu: patch fcompilexoviat2017-09-022-81/+117
| | | | | | | | | | This allows mingw's gfortran to work with MSVC. DLLs are autogenerated using heuristics that should work with most cases. In addition, a libopenblas DLL is compiled from the static lib for use with MSVC. All generated DLLs have randomized names so that no clashes will occur.
