It is indeed such a complex system. I wouldn't say that I've identified
a bottleneck per se, but I've chosen to focus my improvements there. The
idea behind the overhaul is that it attempts to reduce the number of passes
during the peephole optimizer stage - given that I've managed to shave off
I’ve spent some time in the compiler sources now and I’m curious just where
people think the bottle necks for performance actually are. It’s such a
complicated system for anyone one person to have a good understanding of so
it’s not clear where to begin looking.

I'll have to look that one up. I might have reinvented the wheel a bit
with the binary search algorithm that I put on there ages ago, which is of
O(log n) and works even if the range of test values is sparse (I came up
with the algorithm originally for the case block in the peephole optimiser,
I think this was intended for the mailing list - I'm looking forward to it
too. Depends on what Florian says though.
The overhaul primarily increases the speed of compilation, but it makes
some minor improvements to conditional branches here and there.
Nevertheless, I'm always happy to find a

I'll give it a whirl when I next build FPC, since I play with win32 and
win64 optimisations quite a bit. Thanks Marco.
