MIPS Load Immediate

[denniss]

Hey guys, I am struggling right now to get an unsigned integer given a signed integer. I want to convert let's say

 

-1 to 4294967295

-2 to 4294967294

and so on

 

One way to do this is to

multiply the number given say -1 -> 1

and subtract it from 4294967296

 

(note this is for negative case only)

but the maximum is 4294967295

so I want to subtract 4294967295 with -1*(the number given)

and add 1 to it.

 

However, for some reason I cannot store 4294967295 into a register

li $t0, 0xFFFFFFFF will give me -1
