Description (last modified by )
sage.rings.polynomial.polynomial_element.Polynomial
provides an implementation for _xgcd
. This implementation is not correct for polynomials over arbitrary rings. Therefore it should be moved to sage.rings.polynomial.polynomial_element_generic.Polynomial_generic_field
.
The way it currently is, doesn't cause any bugs (except for one which already has a stopgap warning) because only elements of a PID call the _xgcd
method.
