How Difficult is it to Write a Compiler?

If you're writing a real honest-to-God compiler (source language to hardware execution, not a Java/Ruby/Python VM targeted language) these years, and you don't start with LLVM (http://llvm.org) as a basis for code generation, you're really missing the boat.

As an old compiler hacker (from the early 70s), what I've seen of LLVM is that it's a world-class foundation.

Unfortunately, it doesn't do exceptions well - certainly not Windows SEH, and it relies on DWARF2 exception tables + specific runtime library unwinding support.

Apart from that, and the slowness of its instruction selector, though, it's pretty good.
