Earley parser from project cocom (http://cocom.sf.net) satisfies a lot
of your requirements


http://cocom.sourceforge.net/ammunition-13.html


It is a pretty fast parser (>100K lines of C per 1 sec on modern
processors) with minimal cost error recovering and abstract tree
generation described by simple syntax directed translation.


It can generate one abstract or all abstract trees (in a compact form)
for ambigious grammar languages. It also can generate minimal cost
abstract trees.
