From 8c2e4e0689ea244d0ed979171a3d09c9176b8175 Mon Sep 17 00:00:00 2001 From: Simon Marchi Date: Sun, 12 Jul 2020 22:58:51 -0400 Subject: [PATCH] gdb: add accessors to struct dynamic_prop Add setters, to ensure that the kind and value of the property are always kept in sync (a caller can't forget one or the other). Add getters, such that we can assert that when a caller accesses a data bit of the property, the property is indeed of the corresponding kind. Note that because of the way `struct dynamic_prop` is allocated currently, we can't make the `m_kind` and `m_data` fields private. That would make the type non-default-constructible, and we would have to call the constructor when allocating them. However, I still prefixed them with `m_` to indicate that they should not be accessed from outside the class (and also to be able to use the name `kind` for the method). gdb/ChangeLog: * gdbtypes.h (struct dynamic_prop) : New methods. : Rename to... : ... this. Update all users to use the new methods instead. : Rename to... : ... this. Update all users to use the new methods instead.
