+* 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
+  3A1000 processor, The -march=loongson3a is an alias of -march=gs464 for
+  compatibility.
+
 Changes in 2.31:
 
 * Add support for disassembling netronome Flow Processor (NFP) firmware files.
