Subject: [PATCH] lib/ida: remove abandoned macros
Date: Tue, 21 Jan 2020 16:34:05 +0800 [thread overview]
Message-ID: <1579595645-251250-1-git-send-email-alex.shi@linux.alibaba.com> (raw)
3 IDA_ started macros aren't used from commit f32f004cddf8 ("ida: Convert
to XArray"). so better to remove them.
