方法

distutils.ccompiler_opt.CCompilerOpt.feature_ahead(names)[source]#

返回“names”中移除任何隐含特性并保留原始特性的列表。

参数:

‘names’: 序列: 大写的 CPU 特性名称序列。

返回:

按“names”原样排序的 CPU 特性列表

示例

>>> 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"]
