* [3.11] gh-92228: disable the compiler's 'small exit block inlining' ↵Christian Heimes2022-07-071-0/+14
| | | | | | | | | | optimization for blocks that have a line number (GH-94592) (GH-94643) Inlining of code that corresponds to source code lines, can make it hard to distinguish later between code which is only reachable from except handlers, and that which is reachable in normal control flow. This caused problems with the debugger's jump feature. This PR turns off the inlining optimisation for code which has line numbers. We still inline things like the implicit "return None"..

* gh-92203: Add closure support to exec(). (#92204)larryhastings2022-05-062-19/+78
| | | Add a closure keyword-only parameter to exec(). It can only be specified when exec-ing a code object that uses free variables. When specified, it must be a tuple, with exactly the number of cell variables referenced by the code object. closure has a default value of None, and it must be None if the code object doesn't refer to any free variables.

* Use static inline function Py_EnterRecursiveCall() (#91988)Victor Stinner2022-05-043-434/+436
| | | | | | | | | | | | | | | | Currently, calling Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() may use a function call or a static inline function call, depending if the internal pycore_ceval.h header file is included or not. Use a different name for the static inline function to ensure that the static inline function is always used in Python internals for best performance. Similar approach than PyThreadState_GET() (function call) and _PyThreadState_GET() (static inline function). * Rename _Py_EnterRecursiveCall() to _Py_EnterRecursiveCallTstate() * Rename _Py_LeaveRecursiveCall() to _Py_LeaveRecursiveCallTstate() * pycore_ceval.h: Rename Py_EnterRecursiveCall() to _Py_EnterRecursiveCall() and Py_LeaveRecursiveCall() and _Py_LeaveRecursiveCall()

| | | | | | | | | Use FLAG_REF always for interned strings. Refcounts of interned string is very unstable. When compiling same source, refcounts of interned string in the output may be 1 or >1. It makes FLAG_REF usage unstable. To help reproducible build, use FLAG_REF for interned string even if refcnt(obj)==1.

| | | | | | | | | | | 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
