Subject: [PATCH 02/30] Split create_addrmap_from_aranges
Date: Wed, 25 Aug 2021 20:19:09 -0600 [thread overview]
Message-ID: <20210826021937.1490292-3-tom@tromey.com> (raw)
In-Reply-To: <20210826021937.1490292-1-tom@tromey.com>
This patch splits create_addrmap_from_aranges into a wrapper function
and a worker function. The worker function is then used in a later
patch.
