I think Mark and Kenner would like to see GCC performance improve.
I think that is the case for every GCC developper.  However, limited
ressources mean things have to be assigned priority.  Optimizations
have high priorities (cf. regular patches and discussions about such
and such Intermdiate Language Tranformations).  It may be that
an optimization like alias analysis doesn't have the highest priority
but that doesn't mean notbody isn't consider it -- hey, isn't Mark who
implemented the type-based analysis in g++? ;-)
