New issue 2814: _pypyjson should use SIMD when available to skip whitespace characters faster https://bitbucket.org/pypy/pypy/issues/2814/_pypyjson-should-use-simd-when-available
Omer Katz: RapidJSON has implemented whitespace skipping using a variety of SIMD interstices. For [SSE 4.2](https://github.com/Tencent/rapidjson/blob/master/include/rapidjson/reader.h#L281), [SSE 2](https://github.com/Tencent/rapidjson/blob/master/include/rapidjson/reader.h#L332) and [NEON for ARM](https://github.com/Tencent/rapidjson/blob/master/include/rapidjson/reader.h#L417). We can port these functions to C pretty easily and the license of RapidJSON is MIT so that's allowed. The challenge is to detect if the user running PyPy has support for such instructions. _______________________________________________ pypy-issue mailing list pypy-issue@python.org https://mail.python.org/mailman/listinfo/pypy-issue
