Subject: [PATCH 19/24] gdb: make aarch64_za_offsets_from_regnum return za_offsets
Date: Fri, 1 Dec 2023 11:27:32 -0500 [thread overview]
Message-ID: <20231201162751.741751-20-simon.marchi@efficios.com> (raw)
In-Reply-To: <20231201162751.741751-1-simon.marchi@efficios.com>
This is not necessary, but it seems more natural to me to make
aarch64_za_offsets_from_regnum return a za_offsets object, rather than
fill an instance passed by parameter.
Change-Id: I40a185f055727da887ce7774be193eef1f4b9147
