def check_api_version(apiversion, codegen_dir):

Emits a MismatchCAPIWarning if the C API version needs updating.

def check_for_right_shift_internal_compiler_error(cmd):

On our arm CI, this fails with an internal compilation error

The failure looks like the following, and can be reproduced on ARM64 GCC 5.4:

<source>: In function 'right_shift': <source>:4:20: internal compiler error: in expand_shift_1, at expmed.c:2349

ip1[i] = ip1[i] >> in2;

^

Please submit a full bug report, with preprocessed source if appropriate. See <http://gcc.gnu.org/bugs.html> for instructions. Compiler returned: 1

This function returns True if this compiler bug is present, and we need to turn off optimization for the function

def check_long_double_representation(cmd):

Undocumented

def fname2def(name):

Undocumented

def get_api_versions(apiversion, codegen_dir):

Return current C API checksum and the recorded checksum.

Return current C API checksum and the recorded checksum for the given version of the C API version.

def is_released(config):

Return True if a released version of numpy is detected.

def long_double_representation(lines):

Given a binary dump as given by GNU od -b, look for long double representation.

def pyod(filename):

Python implementation of the od UNIX utility (od -b, more exactly).

Parameters

filename : str: name of the file to get the dump from.

Returns

out : seq: list of lines of od output

Notes

We only implement enough to get the necessary information for long double representation, this is not intended as a compatible replacement for od.
