Hi, this ones for the compiler gurus. 

I'm writing a simple compiler based on a C-like language. Everythings
doing alright as far as using Flex and Bison to parse the input. But
now I've got to generating code and stumbled, mainly in the area of
reducing expressions - as far as wanting to reduce 2*2 to 4 but
generate code for 2*var. Anyone that could simply explain how to do
this in Bison/Yacc I'd appreciate it, or a decent website/book on
compilers that is relatively simple and straightforward. I've tried
the GCC source, but I can't seem to get the big picture when it comes
to looking over c-parse.y

Thanks all, please reply by email as well if possible.

Cheers,
Brett
