Well, there's a lot of stuff that can be done on the AST, but for things 
like peephole optimization, register allocation, constant folding, 
inlining of runtime routines, tail call elimination etc. you definitely 
need to consider the target code (which most often is an abstract 
assembler-like code which then gets translated to the real native code, 
at least nowadays).

In principle, you could also design your own AST representation of the 
target and apply your optimizations to that, but some kinds of 
optimizations are pretty hairy, so why reinvent the wheel when there's 
already something as comprehensive as LLVM out there?

No sweat. :) It would be cool if you could try Pure and provide some 
feedback on how well it works for your purposes.
