--- Comment #2 from Richard Biener <rguenth at gcc dot gnu.org> --- So the easiest thing is to move the last forwprop pass across phiopt and after fold_builtins. Another possibility would be to get rid of the redundant second __builtin_assume_aligned as soon as we discover that (in CCP). Testing the latter.
