I am not sure what you mean by freeing up TYPE_CANONICAL again :) but I was playing with idea of streaming the alias sets from WPA to ltrans. It may simplify things especially if our canonical type logic gets more complex... In particular I would eventually like to avoid pesimizing C/C++ code just becuase we worry about compatibility with Fortran and such and had some patches for this direction but so far there was more pressing issues with TBAA than this. We do not really use TYPE_CANONICAL outside of tree-ssa-alias and alias.c Honza > from FEs which use it before and recompute it possibly in different > ways ... > > Richard.
