* GH-98831: Implement array support in cases generator (#100912)Guido van Rossum2023-01-171-47/+55
| | | | | | | | You can now write things like this: ``` inst(BUILD_STRING, (pieces[oparg] -- str)) { ... } inst(LIST_APPEND, (list, unused[oparg-1], v -- list, unused[oparg-1])) { ... } ``` Note that array output effects are only partially supported (they must be named `unused` or correspond to an input effect).

* 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: Modernize a ton of simpler instructions (#100545)Guido van Rossum2022-12-281-127/+126

* Revert "gh-100288: Specialise LOAD_ATTR_METHOD for managed dictionaries ↵Ken Jin2022-12-231-25/+0
| | | | | (GH-100289)" (#100468) This reverts commit c3c7848a48b74a321632202e4bdcf2f465fb1cc6.

* GH-98522: Add version number to code objects. (GH-98525)Mark Shannon2022-12-091-0/+1
| | | | | | * Add version number to code object for better versioning of functions. * Improves specialization for closures and list comprehensions.
* GH-100110: Specialize FOR_ITER for tuples (GH-100109)Ken Jin2022-12-091-0/+23
| | | * Specialize FOR_ITER for tuples
* 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-98831: Typed stack effects, and more instructions converted (#99764)Guido van Rossum2022-12-081-244/+245
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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-98831: Add `macro` and `op` and their implementation to DSL (#99495)Guido van Rossum2022-11-231-43/+60
| | | | | | | | | | | | | | 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>
