For the xor error,it seems the code has been optimized using lonngson specific instructs, a gcc 4.x is needed and -march,-mtune should be set to loongson.sorry I don't remember the exact flags. Ldc is for mips3 and aboves,your compiler is using mips1.use .set mips3 if it is assembly code, otherwise tweak the flags like the first one
