# numpy.distutils.ccompiler_opt.CCompilerOpt.feature_ahead

method

distutils.ccompiler_opt.CCompilerOpt.feature_ahead(names)

  Return list of features in ‘names’ after remove any implied features and keep the origins.

  Parameters:
    ‘names’: sequence

      sequence of CPU feature names in uppercase.

  Returns:
    list of CPU features sorted as-is ‘names’

  Examples

      >>> self.feature_ahead(["SSE2", "SSE3", "SSE41"])
      ["SSE41"]
      # assume AVX2 and FMA3 implies each other and AVX2
      # is the highest interest
      >>> self.feature_ahead(["SSE2", "SSE3", "SSE41", "AVX2", "FMA3"])
      ["AVX2"]
      # assume AVX2 and FMA3 don't implies each other
      >>> self.feature_ahead(["SSE2", "SSE3", "SSE41", "AVX2", "FMA3"])
      ["AVX2", "FMA3"]
