* GH-98831: Identify instructions that don't use oparg (#100957)Guido van Rossum2023-01-142-3/+13
| | | | | | | For these the instr_format field uses IX instead of IB. Register instructions use IX, IB, IBBX, IBBB, etc. Also: Include the closing '}' in Block.tokens, for completeness
* Don't double count misses. (GH-100984)Mark Shannon2023-01-131-0/+3

* GH-98831: Add some tests for generate_cases.py (#100763)Guido van Rossum2023-01-061-0/+310
| | | | | | - This doesn't cover everything (far from it) but it's a start. - This uses pytest, which isn't ideal, but was quickest to get started. Co-authored-by: Kumar Aditya <59607654+kumaraditya303@users.noreply.github.com>

| | | | | | | | (These aren't used yet, but may be coming soon, and it's easier to keep this tool the same between branches.) Added a sanity check for all this to compile.c. Co-authored-by: Irit Katriel <iritkatriel@yahoo.com>

* GH-98831: Add DECREF_INPUTS(), expanding to DECREF() each stack input (#100205)Guido van Rossum2022-12-171-1/+5
| | | | | | | | | | | | | | | | | | | The presence of this macro indicates that a particular instruction may be considered for conversion to a register-based format (see https://github.com/faster-cpython/ideas/issues/485). An invariant (currently unchecked) is that `DEOPT_IF()` may only occur *before* `DECREF_INPUTS()`, and `ERROR_IF()` may only occur *after* it. One reason not to check this is that there are a few places where we insert *two* `DECREF_INPUTS()` calls, in different branches of the code. The invariant checking would have to be able to do some flow control analysis to understand this. Note that many instructions, especially specialized ones, can't be converted to use this macro straightforwardly. This is because the generator currently only generates plain `Py_DECREF(variable)` statements, and cannot generate things like `_Py_DECREF_SPECIALIZED()` let alone deal with `_PyList_AppendTakeRef()`.

* gh-81057: Move _Py_RefTotal to the "Ignored Globals" List (gh-100203)Eric Snow2022-12-122-4/+7
| | | | | We can't move it to _PyRuntimeState because the symbol is exposed in the stable ABI. We'll have to sort that out before a per-interpreter GIL, but it shouldn't be too hard. https://github.com/python/cpython/issues/81057

* gh-81057: Move Threading-Related Globals to _PyRuntimeState (#100084)Eric Snow2022-12-092-6/+2

* GH-98831: Generate things in the input order (#100123)Guido van Rossum2022-12-081-24/+32
| | | | This makes it easier to see what changed in the generated code when converting an instruction to super or macro.

* GH-98831: Typed stack effects, and more instructions converted (#99764)Guido van Rossum2022-12-082-135/+179
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
