Subject: Handle new v9 insn argument codes, and delete support for obsolete ones.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=93fd00fbbf104fc022215ecff7cef252bd4babb8;p=binutils-gdb.git

Handle new v9 insn argument codes, and delete support for obsolete ones.
Otherwise not updated or tested, since v9 support is obviously incomplete,
and it can't possibly work right without some effort.
