Integer Overflow IA 32

Question

How does overflow work in ia-32?

For instance, what would happen to the following code? What flags would it throw?

movl $0x1, %eax
addl $7fffffff, %eax

Thanks!

Answer 1

If memory serves, addition sets the overflow flag is set when the sign bit changes without the carry bit being set. 1 + 0x7FFFFFFF would set overflow, clear carry, and clear zero.
