commit a0176d8d12161136bbdf73558d32407ac98c9753
Author: David Guillen Fandos <david@davidgf.net>
Date: Thu Jun 15 04:45:03 2023 +0100
Add additional missing Allegrex CPU instructions
Allegrex supports some MIPS32 and MIPS32r2 instructions (albeit with
some encoding differences) such as bit manipulation (ins/ext) and MLA
(madd/msub). It also features some new instructions like wsbw and
min/max or device-specific ones such as mfic.
