Subject: Add rotation instructions to MIPS Allegrex CPU
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=d29b94fc9f365de8002a9566df5bd8a45c7c8f1d;p=binutils-gdb.git

Add rotation instructions to MIPS Allegrex CPU

The Allegrex CPU supports bit rotation instructions as described in the
MIPS32 release 2 CPU (even though it is a MIPS-2 based CPU).
