First of all, thanks for working on compiler optimizations. I think it's very important.
As of benchmark - there is a simple 3D ray tracer benchmark written on several languages including Pascal.
There is forum topic about it with source code:
There are also some optimizations made by hand e.g. loop unrolling etc. It may help to analyze optimizer results.
Best Regards, George

> Given my recent work with the peephole optimizer, one thing that sprung to mind is that I don't have a project that tests for performance gains in a 'real world' program, where little optimisations add up over time. Given that my x86-64 optimizer overhaul is rather substantial and makes a lot of improvements when it comes to conditional jumps and code efficiency, is there a benchmark that could be used to show the performance improvement compared to the trunk? There are small ones that test individual components, but nothing substantially large that I'm aware of.
