This should not be needed since have no ".set noreorder" in the file, so the assembler should add a nop in the delay slot, after "jr s1". I have this on an objdumped relocate_kernel.o, so the assembler does add the nop: [...] 000000a4 <done>: a4: 02200008 jr s1 a8: 00000000 nop [...] Regards, -- Nicolas Schichan
