| | | | | | | | (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-100146: Steal references from stack when building a list (#100147)L. A. F. Pereira2023-01-031-5/+2
| | | | | | | | | | When executing the BUILD_LIST opcode, steal the references from the stack, in a manner similar to the BUILD_TUPLE opcode. Implement this by offloading the logic to a new private API, _PyList_FromArraySteal(), that works similarly to _PyTuple_FromArraySteal(). This way, instead of performing multiple stack pointer adjustments while the list is being initialized, the stack is adjusted only once and a fast memory copy operation is performed in one fell swoop.

* GH-98831: Add DECREF_INPUTS(), expanding to DECREF() each stack input (#100205)Guido van Rossum2022-12-171-18/+13
| | | | | | | | | | | | | | | | | | | 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-98831: Typed stack effects, and more instructions converted (#99764)Guido van Rossum2022-12-081-225/+121
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | 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>
