Part 2: Weird Control Flow (10%)

  • Reverse all printf, scanf, and __builtin_puts statements in a basic block. If there are k such statements in a basic block, the first statement will be switched with the last statement, the second statement will be switched with the (k-1)th statement, and so on. At a function call such as scanf and printf, Gcc copies the arguments to a temporary variable. For the project, you need to move these copy statements with the call.
