Gareth,
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.
AFAIR Pascal version almost as fast as Java one and slightly faster than
Javascript.
Speaking of the optimiser overhaul, what are timings like for others?

Thanks George,
I've finished and debugged my optimizer overhaul, although performance
varies. It is predominantly faster than the existing peephole optimizer,
but not always as fast as I'd like (no more than a few seconds). I figure
I might have introduced one or two bottlenecks during my
Gareth, I like very much what you do about compiler optimizations.
From my point of view, execution speed is the most valuable, but of course 17%
of compilation speed increase is worth it!
If you want to have a big test case, and potentially find regressions, you may
try the TestSQL3 project
Well, compiling Lazarus is what I've been doing to test the compiler's
speed, and I've got some promising results:

Though the speed of the runs varies a lot depending on what my system is
doing, especially when I switch back and forth

Hi everyone,
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
