so I've come across a problem with my PCSpim program, after looking I still cannot find the right solution, I thought it may be the 'align' directive, either I'm missing one or I am missing it.
Here is the beginning of the program, initializing the array
.data
.align 2 # Let's make sure that it's aligned
Z: .word 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22, 23,
# above we allocated and initialized 13
# elements of array Z
.space 80 # here we allocated space here for 20 elements
.text
.globl main
main: # main has to be a global label
addu $s7, $0, $ra # save the return address
# in a global register
la $s3, Z # $s3 has the starting address of Z
===============================================================
I think it is around here where is messed up
#-------------------------------------Compute Z[12] = Z[k] + z[k+j]
.text
.align 2
la $t3, Z # put address of Z into $t3
li $t5, 12 # put the index into $t5
add $t5, $t2, $t3 # combine the two components of the address
sw $t4, 0($t1) # store the value into the array cell
#-----------------------------------printing Z[12] = Z[k] + z[k+j] on the console
.data
.globl message4
message4: .asciiz "\nZ[12] = " #string to print
.text li $v0, 4 # print_str (system call 4)
la $a0, message # takes the address of string as an argument
syscall
li $v0, 1 # print_int (system call 1)
add $a0, $0, $t1 # put value to print in $a0
syscall
Any suggestions would be greatly appreciated! :)
