| | | | | | | | 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).

| | | | | | | | (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.
