I made a previous attempt last August: PR gh-108500. It made _statistics._normal_dist_inv_cdf() 2x slower because of the usage of the legacy METH_VARARGS calling convention, instead of more recent and faster METH_FASTCALL. This new attempt keeps METH_FASTCALL thanks to recent Argument Clinic changes, and so it has no impact on performance. Or maybe it's a little bit faster thanks to inlining. |
Argument Clinic now inlines _PyArg_CheckPositional() for the limited C API. The generated code should be as fast or even a little bit faster.
