This was always the original idea to replace alignment propagation by bitwise ccp. I suppose we only have issue here because nonzero bits are not tracked for pointers so we need to feed the original lattices by hand? We could also make use of VR ranges and bits while evaultaing predicates in ipa-inline-analysis. I can look into it after returning from Leeds. Honza > in the end it's Martins/Honzas call here.
