>_PyInterpreterState_GET(): > mov rax,QWORD PTR [rip+0x22a7dd] # 0x743118 <_PyRuntime+568> > mov rax,QWORD PTR [rax+0x10] While working on bpo-39465, I wrote PR 20767 to optimize _PyInterpreterState_GET(): single instruction instead of two: * Add _PyRuntimeState.interp_current member: atomic variable * _PyThreadState_Swap() sets _PyRuntimeState.interp_current But I failed to measure any performance difference. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40522> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
