.set <flag>
Sets (and clears) various flags that affect generated code. The following table may not be a complete list.
Flag
noreorder
Turns off reordering of instructions. When on, t.i. when the assembler is reordering, it will put the last instruction before j or jr after the jump so it'll be in the branch delay slot. When off, you'll have to do it yourself. mips3
Tells the assembler that it can use the MIPS III instructions. Withouth it as simulates 64 bit instructions, and believe me, that's something you don't want. reorder
Allows the assembler to reorder instructions; see noreorder pop
Not really a flag but restores the state of the flags to what it was before the last .set push; see push. push
Nor really a flag but saves the status of the flags so it can be restored with .set pop. Not really useful (I think) outside inline assembly. Use in pairs with .set pop.
