* GH-100110: Specialize FOR_ITER for tuples (GH-100109)Ken Jin2022-12-094-12/+62
| | | * Specialize FOR_ITER for tuples
* gh-81057: Move Threading-Related Globals to _PyRuntimeState (#100084)Eric Snow2022-12-094-48/+24

* gh-81057: Move Ceval Trampoline Globals to _PyRuntimeState (gh-100083)Eric Snow2022-12-091-30/+14
| | | https://github.com/python/cpython/issues/81057
* GH-98831: Generate things in the input order (#100123)Guido van Rossum2022-12-081-237/+237
| | | | This makes it easier to see what changed in the generated code when converting an instruction to super or macro.
* gh-81057: Move time Globals to _PyRuntimeState (gh-100122)Eric Snow2022-12-081-0/+5
| | | https://github.com/python/cpython/issues/81057
* GH-98831: Typed stack effects, and more instructions converted (#99764)Guido van Rossum2022-12-082-469/+366
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Stack effects can now have a type, e.g. `inst(X, (left, right -- jump/uint64_t)) { ... }`. Instructions converted to the non-legacy format: * COMPARE_OP * COMPARE_OP_FLOAT_JUMP * COMPARE_OP_INT_JUMP * COMPARE_OP_STR_JUMP * STORE_ATTR * DELETE_ATTR * STORE_GLOBAL * STORE_ATTR_INSTANCE_VALUE * STORE_ATTR_WITH_HINT * STORE_ATTR_SLOT, and complete the store_attr family * Complete the store_subscr family: STORE_SUBSCR{,DICT,LIST_INT} (STORE_SUBSCR was alread half converted, but wasn't using cache effects yet.) * DELETE_SUBSCR * PRINT_EXPR * INTERPRETER_EXIT (a bit weird, ends in return) * RETURN_VALUE * GET_AITER (had to restructure it some) The original had mysterious `SET_TOP(NULL)` before `goto error`. I assume those just account for `obj` having been decref'ed, so I got rid of them in favor of the cleanup implied by `ERROR_IF()`. * LIST_APPEND (a bit unhappy with it) * SET_ADD (also a bit unhappy with it) Various other improvements/refactorings as well.

* gh-99741: Implement Multi-Phase Init for the _xxsubinterpreters Module ↵Eric Snow2022-12-051-56/+128
| | | | | | | (gh-99742) _xxsubinterpreters is an internal module used for testing. https://github.com/python/cpython/issues/99741
* bpo-15999: Accept arbitrary values for boolean parameters. (#15609)Serhiy Storchaka2022-12-032-5/+5
| | | builtins and extension module functions and methods that expect boolean values for parameters now accept any Python object rather than just a bool or int type. This is more consistent with how native Python code itself behaves.

| | | | | | | | | | | | | | Newly supported interpreter definition syntax: - `op(NAME, (input_stack_effects -- output_stack_effects)) { ... }` - `macro(NAME) = OP1 + OP2;` Also some other random improvements: - Convert `WITH_EXCEPT_START` to use stack effects - Fix lexer to balk at unrecognized characters, e.g. `@` - Fix moved output names; support object pointers in cache - Introduce `error()` method to print errors - Introduce read_uint16(p) as equivalent to `*p` Co-authored-by: Brandt Bucher <brandtbucher@gmail.com>
