ALT C/C++ function: int add(int a, int b) { if (a > 0 && b > 0) { // If both numbers are positive... if (a + b < 0) { // And the result is negative... puts("OH NO! An Integer Overflow!"); return 0; } } return a + b; } Was converted during compilation to (result of gcc -fdump-tree-all -O3): Removing basic block 3 Merging blocks 2 and 4 add (int a, int b) { int _12; <bb 2> : _12 = a_7(D) + b_8(D); return _12; }
