* Merge pull request #11479 from wdirons/fix_define_for_ppc64_and_ppc64leCharles Harris2018-07-051-4/+6
|\ | | | | BUG: Fix #define for ppc64 and ppc64le
| * BUG: Fix #define for ppc64 and ppc64leWilliam D. Irons2018-07-021-4/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current logic for defining NPY_CPU_PPC64LE and NPY_CPU_PPC64 is incorrect for two reasons: 1) The elif defined for __powerpc__ is proceesed first so any ppc64le or ppc64 system is defined as NPY_CPU_PPC. 2) __ppc64le__ is not defined on a ppc64le system. __PPC64__ is defined and so is __powerpc64__ but the check for little or big endian needs to be done seperately. This pull request fixes the defines for ppc64le and ppc64. Note: This really isn't a issue in the numpy code base at this time because the only place this variable is referenced is in npy_endian.h as a fallback in case endian.h is not on the system. It would be good to fix in case future code does reference these defines.

|\ \ \ | | | | | | | | BUG: Advanced indexing assignment incorrectly took 1-D fastpath
| * | | BUG: Advanced indexing assignment incorrectly took 1-D fastpathSebastian Berg2018-07-023-20/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the index array was non contiguous and not 1D the assignment 1D fastpath (indexed array being 1D) was incorrectly taken (also the assignment value had to be 0D for this to happen). This caused the iteration to use the itemsize as a stride, since it incorrectly assumed the array must be contiguous. The commit additionally adds an assert to the STRIDE fetching macro. Closes gh-11467.

Also rather drastically rewrote, to use a new parser with simple conversion functions to replace part of the enormous switch/case structure, process out separately, and check for duplication after the parsing. Reduces the overhead as follows: ``` import numpy as np a = np.array(1) b = np.empty_like(a) %timeit np.positive(a) # 352->348 ns %timeit np.positive(a, subok=True) # 606->501 ns %timeit np.positive(a, where=True) # 586->503 ns %timeit np.positive(a, where=True, subok=True) # 695->531 ns %timeit np.positive(a, b) # 354->352 ns %timeit np.positive(a, out=b) # 557->480 ns %timeit np.positive(a, out=b, subok=True) # 668->506 ns %timeit np.positive(a, out=b, where=True, subok=True) # 752->536 ns ```

This isn't a straight revert, it restores to the 1.15.x version of the relevant code. Closes #11431.

| |_|_|/ |/| | | | | | | | | | | | | | | | | | | | | | | Overall, it likely doesn't matter much for performance, but it is more logical and more consistent with what python does: reverse operators are not called if the forward one of a given class already returned NotImplemented.
