Subject: [PATCH 5/5] replace convert_load_instruction() by replace_with_pseudo()
Date: Sun, 29 Nov 2020 15:49:22 +0100 [thread overview]
Message-ID: <20201129144922.56209-6-luc.vanoostenryck@gmail.com> (raw)
In-Reply-To: <20201129144922.56209-1-luc.vanoostenryck@gmail.com>
These two functions are now exactly the same, so replace the
first one by the second one.
