in arch/mips/Makefile, we use the -mcpu=r4600 flag for MIPS32. What's interesting is that the use of this flag can cause the toolchain to generate incorrect code. For example: la k0, 1f nop 1: nop The la macro is split into a lui and a daddiu. The daddiu is not correct for a mips32 cpu. Getting rid of the -mcpu=4600 fixes the problem and the daddiu is then changed addiu. Is there a truly correct -mcpu option for a mips32 cpu? Pete
