[PATCH v2 4/5] or1k: Add the l.muld, l.muldu, l.macu, l.msbu insns
- From: Stafford Horne <shorne at gmail dot com>
- To: binutils at sourceware dot org

- Subject: [PATCH v2 4/5] or1k: Add the l.muld, l.muldu, l.macu, l.msbu insns
- References: <20181001071001.20446-1-shorne@gmail.com>
From: Richard Henderson <rth@redhat.com>
Also fix the incorrect definitions of multiply and divide carry and
overflow float.
Changes to the instructions are made in the .cpu file, then we
regenerate the binutils and sim files.
The changes also required a few fixups for tests and additional sim helpers.
yyyy-mm-dd Richard Henderson <rth@twiddle.net>
