Yes. If you are using 4.3+, alias analysis is a TODO item, so it's run 
if a pass requests it. If you use -fdump-tree-salias-vops, you'll get 
the very first dump of alias analysis (after the creation of structure 
vars). Otherwise, just use -fdump-tree-all-vops. You can grep which 
passes requested alias analysis by grepping for 'points-to' in the dumps.

If you are using pre 4.3, then -fdump-tree-alias-vops will work.
