Subject: [PATCH 3/4] gdb: Migrate frame unwinders to use C++ classes
Date: Wed, 6 Mar 2024 13:51:34 +0100 [thread overview]
Message-ID: <20240306125135.766567-4-blarsen@redhat.com> (raw)
In-Reply-To: <20240306125135.766567-1-blarsen@redhat.com>
Frame unwinders have historically been a structure populated with
callback pointers, so that architectures (or other specific unwinders)
could install their own way to handle the inferior. However, since
moving to c++, we could use polymorphism to get the same functionality
in a more readable way. Polymorphism also makes it simpler to add new
functionality to all frame unwinders, since all that's required is
adding it to the base class.
As part of the changes to add support to disabling frame unwinders,
this commit makes the first baby step in using polymorphism for the
frame unwinders, by making frame_unwind a virtual class, and adds a
couple of new classes. The main class added is frame_unwind_legacy,
which works the same as the previous structs, using function pointers
as callbacks. This class was added to allow the transition to happen
piecemeal. New unwinders should instead follow the lead of the other
classes implemented.
2 of the others, frame_unwind_python and frame_unwind_trampoline, were added
because it seemed simpler at the moment to do that instead of reworking
the dynamic allocation to work with the legacy class, and can be used as
an example to future implementations.
Finally, the cygwin unwinder was converted to a class since it was most
of the way there already.
