* gh-91719: Add pycore_opcode.h internal header file (#91906)Victor Stinner2022-04-26
| | | | | | | | | | | Move the following API from Include/opcode.h (public C API) to a new Include/internal/pycore_opcode.h header file (internal C API): * EXTRA_CASES * _PyOpcode_Caches * _PyOpcode_Deopt * _PyOpcode_Jump * _PyOpcode_OpName * _PyOpcode_RelativeJump
* GH-91719: Make MSVC generate somewhat faster switch code (#91718)Guido van Rossum2022-04-21
| | | | | | | | | | | Apparently a switch on an 8-bit quantity where all cases are present generates a more efficient jump (doing only one indexed memory load instead of two). So we make opcode and use_tracing uint8_t, and generate a macro full of extra `case NNN:` lines for all unused opcodes. See https://github.com/faster-cpython/ideas/issues/321#issuecomment-1103263673
