mips r6 (an incompatible isa from traditional mips) removes the hi and lo registers used for mul/div results. older gcc versions accepted them in the clobber list for asm, but their presence is incorrect and breaks on later versions. in the process of fixing this, the clobber list for 32-bit mips syscalls has been deduplicated via a macro like on mips64 and n32.
