numpy.distutils.ccompiler_opt.CCompilerOpt.feature_implies

method

distutils.ccompiler_opt.CCompilerOpt.feature_implies(names, keep_origins=False) [source]

Return a set of CPU features that implied by ‘names’

Parameters

names: str or sequence of str

CPU feature name(s) in uppercase.

keep_origins: bool

if False(default) then the returned set will not contain any features from ‘names’. This case happens only when two features imply each other.

Examples

>>> self.feature_implies("SSE3")
{'SSE', 'SSE2'}
>>> self.feature_implies("SSE2")
{'SSE'}
>>> self.feature_implies("SSE2", keep_origins=True)
# 'SSE2' found here since 'SSE' and 'SSE2' imply each other
{'SSE', 'SSE2'}
