1.
Convert the following C code to MIPS
. for (i=0; i < n; i++) {
A[i] = A[i] + i;
}
Solution
main()
{
int A[10],i,n;
for (i=0; i < n; i++)
{
A[i] = A[i] + i;
}
}
code in mips i have so far:
main:
@ args = 0, pretend = 0, frame = 48
@ frame_needed = 1, uses_anonymous_args = 0
@ link register save eliminated.
