numpy.distutils.ccompiler_opt.CCompilerOpt.feature_untied

method

distutils.ccompiler_opt.CCompilerOpt.feature_untied(names) [source]

same as ‘feature_ahead()’ but if both features implied each other and keep the highest interest.

Parameters

‘names’: sequence

sequence of CPU feature names in uppercase.

Returns

list of CPU features sorted as-is ‘names’

Examples

>>> self.feature_untied(["SSE2", "SSE3", "SSE41"])
["SSE2", "SSE3", "SSE41"]
# assume AVX2 and FMA3 implies each other
>>> self.feature_untied(["SSE2", "SSE3", "SSE41", "FMA3", "AVX2"])
["SSE2", "SSE3", "SSE41", "AVX2"]
