This la
translates into a lui
followed by a ori
(just as we previously did by hand).
Here is a SPIM example using
la
.
To run it in SPIM,
first look in the settings menu and check
"allow pseudo instructions"
and remove the check from "bare machine".
## addEm.asm ## program to add two integers ## .text .globl main main: la $t0,val2 # put a 32-bit address into $t0 lw $t1,0($t0) # load first value, 2 lw $t2,4($t0) # load second value, 3 addu $t1,$t1,$t2 # calc. sum .data val0: .word 0 val1: .word 1 val2: .word 2 val3: .word 3 val4: .word 4 val5: .word 5 ## end of addEm.asm
Execute the program by pushing F10 for each machine instruction.
