From: Tom Tromey Date: Wed, 10 Aug 2022 20:42:22 +0000 (-0600) Subject: Remove MI version 1 X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=975249ff4e26;p=binutils-gdb.git Remove MI version 1 MI version 1 is long since obsolete. Several years ago, I filed PR mi/23170 for this. I think it's finally time to remove this. Any users of MI 1 can and should upgrade to a newer version.
