Subject: [PATCH 09/24] gdb: remove frame_register
Date: Wed, 8 Nov 2023 00:00:53 -0500 [thread overview]
Message-ID: <20231108051222.1275306-10-simon.marchi@polymtl.ca> (raw)
In-Reply-To: <20231108051222.1275306-1-simon.marchi@polymtl.ca>
From: Simon Marchi <simon.marchi@efficios.com>
I was going to change frame_register to take the "next frame", but I
realized that doing so would make it a useless wrapper around
frame_register_unwind. So, just remove frame_register and replace uses
with frame_register_unwind.
Change-Id: I185868bc69f8e098124775d0550d069220a4678a
