+* The MIPS port now supports the Loongson 3A1000 processor, aka Loongson3a,
+ which implements the MIPS64r2 ISA, the Loongson-mmi ASE, Loongson-cam ASE
+ and Loongson-ext ASE instructions. Add -march=gs464 option for Loongson

+ compatibility.

Changes in 2.31:
* Add support for disassembling netronome Flow Processor (NFP) firmware files.
