I've written a compiler backend for lcc. I've done alot of micro tests, which worked fine, but on my first bigger programm i get the error:
error in _rule-- Bad goal nonterminal xxxxxx
where the xxxxxx varies each time i try to compile.
Is their any way to find out which nonterminal is missing in my backend?

Debug the compiler. Put a breakpoint in _rule and see what you are
compiling!
In this years working with lcc I have developed a pretty printer for
lcc's intermediate language, and a sixth (or seventh) sense for
getting at the missing rule.
