…ythonGH-155219) They were emitted in the iteration order of a set of group identifiers. The identifiers of the groups before the required parameters are small negative integers, -1 and -2 have the same hash, so their order depended on the size of Py_hash_t, and the code generated on a 32-bit platform differed from the checked in one. They are now emitted in the order of the parameters.

They were emitted in the iteration order of a set of group identifiers.
The identifiers of the groups before the required parameters are small
negative integers, -1 and -2 have the same hash, so their order depended
on the size of Py_hash_t, and the code generated on a 32-bit platform
differed from the checked in one.
They are now emitted in the order of the parameters.
