Hi everyone,
This has been something that has been on my mind for a while now, but
with my increasingly more complex optimisations being developed for the
Free Pascal Compiler and the code becoming an ever bigger spiderweb of
conditions, it got me to start wondering... might compiler optimisat
This is an interesting idea indeed.

That's fair. Currently in my eyes it's more of an academic curiosity

I wouldn't advocate a neural network within FPC since, yes, it would be
unbelievably slow, very difficult to port and even more difficult to
maintain and verify... not just to confirm correct output (e.g. BSR is
good as an approximation to the expression "floor(log2(x))", but it has
some awkwar

An alternative could be to specify the peephole optimizations in a

I'm liking these discussions!
I have done some refactoring, such as attempting to 'factor out' common
conditions (sometimes a matching instruction, but also commonly the
operand types). Sometimes I choose not to factor - for example,
sometimes I try to compute relatively cheap conditions firs
