[question] why just replace the inline keyword with predefined macro?

[dzhwinter]

This is just a question about the source code. To improve the performance, it will be benefit to use inline function as many as possible. The MSHADOW_XINLINE is a force inline macro which defined in base.h. But sometimes inline key word appear here and there. for example, https://github.com/dmlc/mshadow/blob/master/mshadow/expression.h#L137 why just replace the inline keyword with predefined macro? Is it matter the performance? Or just use inline keywords where we can make sure that function will be execute in CPU .
