Subject: [PATCH 24/34] Add backpointer from windows_thread_info to windows_process_info
Date: Wed, 8 May 2024 00:42:23 +0100 [thread overview]
Message-ID: <20240507234233.371123-25-pedro@palves.net> (raw)
In-Reply-To: <20240507234233.371123-1-pedro@palves.net>
The next patch will move some duplicated code in gdb and gdbserver to
gdb/nat/windows-nat.c, where it would be convenient to get at the
Windows process info of a given Windows thread info, from within a
windows_thread_info method.
I first thought of passing down the windows_process_info pointer as
argument to the windows_thread_info method, but that looked a bit odd.
I think it looks better to just add a back pointer, so that's what
this patch does. The following patch will then add a use of it.
I suspect this will help moving more duplicated code to
gdb/nat/windows-nat.c in the future, too.
