What I've seen seems to be ad hoc stuff with code gen going done in a pass
or two. This is fine for simple languages like pascal and c, but I'm doing
Ada, so it really needs to be fairly aggressive.

[I'd think the aggressive stuff would be largely machine independent,
figuring out what's a constant so it can do stuff at compile time
rather than in the code. Once you've done that, adding two numbers
together or deferencing a pointer is pretty much the same in any
language. -John]
