2021-03-08Introduce class operationTom Tromey1-0/+36
This patch introduces class operation, the new base class for all expression operations. In the new approach, an operation is simply a class that presents a certain interface. Operations own their operands, and management is done via unique_ptr. The operation interface is largely ad hoc, based on the evolution of expression handling in GDB. Parts (for example, evaluate_with_coercion) are probably redundant; however I took this approach to try to avoid mixing different kinds of refactorings. In some specific situations, rather than add a generic method across the entire operation class hierarchy, I chose instead to use dynamic_cast and specialized methods on certain concrete subclasses. This will appear in some subsequent patches. One goal of this work is to avoid the kinds of easy-to-make errors that affected the old implementation. To this end, some helper subclasses are also added here. These helpers automate the implementation of the 'dump', 'uses_objfile', and 'constant_p' methods. Nearly every concrete operation that is subsequently added will use these facilities. (Note that the 'dump' implementation is only outlined here, the body appears in the next patch.) gdb/ChangeLog 2021-03-08 Tom Tromey <tom@tromey.com> * expression.h (expr::operation): New class.
