Question
Give me answer fast please.
Consider the high level code:
int f, g, y //global 64-bit variables
int sum (int a, int b) { // at memory address
XO+1000.
return (a +b)
}
int main (void) // at memory address XO +
800
{
f=2;
g=3;
y= sum (f, g);
return y;
}
Convert this code to LEGV8, making valid
assumptions about registers and register
use. Note
that brackets and global variable
declarations are not affecting the addresses
of the instructions
in memory.
