MIPS Shift Instruction

Question

In an sll instruction in MIPS, it can only take 5-bits. How would the shift work if the shift amount was more than 31? How do we represent that with 5-bits?

Thanks

If you're on a 32-bit CPU, 31 is the most bits you can shift. — Gabe, Oct 29 '11 at 03:39

You cannot. SLL is only for 32-bit values, where shifting more than 31 places makes no sense. Use DSLL/DSLL32 or DSLLV for 64-bit values.

Oh right - stupid question I'm sorry I got carried away with my complicated project that now I'm over-complicating everything. – darksky Oct 29 '11 at 17:02
