Just a quick update. Here is the change list:

• Changed from using std::string to using const char * to improve overall speed
• Changed SuperRoot::PopProfile() and SuperStack::Pop() to accept a name parameter, this helps SuperProfiler to find any mismatches in pushes and pops
• Added SuperException which is thrown if an unmatched pop is detected (really useful actually)
• Added SUPER_PROFILE_PUSH and SUPER_PROFILE_POP macros which are useful if you want to access SuperProfile from a scripting langauge that doesn’t support RAII (cough, Lua, cough), Still use SUPER_PROFILE whenever you can however
• Fixed a bug when there was no SUPER_PROFILE in a root parent function call (such as a main function). I would suggest not profiling a main type function, anything that only returns at exit

SuperProfiler is a library I wrote to help us track down performance issues in Zero Gear. It is open source so anyone can use it (and hopefully help make it better!).

You simply place a piece of code at the start of any function you want to profile and SuperProfiler takes care of the rest.

An example…


void SomeFunction2(int var1)
{
    SUPER_PROFILE(”void SomeFunction2(int var1)”);
    var1++;
}

void main(void)
{
    SomeFunction1();
    SuperProfiler::TextOutput textOutput(”SuperProfilerResults.txt”);
    SuperProfiler::Root::OutputResults(textOutput));
}


and in SuperProfilerResults.txt is…
