Nios/increment align

Write a function that increments a 32-bit word located in memory. The location to modify is passed as the first parameter to the function. This pointer is not necessarily 4-byte aligned, but your routine must only do properly aligned accesses.

void inc (int* p);

Expected solution length: Around 20 lines.

Sample Input

 Pointer: .word 1234

Sample Output

(memory changed to 1235)

.data
.byte 0    # Test with an unaligned word.
Pointer: .word 1234

.text
.global _start
_start:
    movia r4, Pointer
    call inc
