If you can observe any different the the compiler is not allowed to remove the object. Discusses ways in which the Microsoft® Visual C++® compiler can optimize source code for speed and size and tells why code size matters. Even with g++ -O0 (yes, -O0 !), this happens. Open the project's Property Pages dialog box. For details, see How to: Open Project Property Pages. If you're on Windows, use AMD's CodeAnalyst. C++ run-time support routines obviously have a significant cost, because otherwise such behavior would have be inlined. GCC can use that data to optimize conditionals to perform as quickly as possible in the expected case, with slightly slower execution in the unexpected case. Can anyone help me to optimize this bubble sort program? The C++ Standard Template Library (STL) provides the template function sort that implements a comparison sort algorithm. 3.3.2 Optimization Considerations When Mixing C/C++ and Assembly 59 3.5.1 Use Caution With asm Statements in Optimized Code . I bet the Intel compiler does, too. Start your free 10-day trial of Safari. Both the current version of VC++ and GCC do tail call optimizations fairly well and even for mutually recursive calls.
