------- Additional Comments From rth at gcc dot gnu dot org 2005-03-10 13:57 ------- I'll agree that modified_{in,between}_p need to check the address for changes, since that controls the ultimate value that is accessed.
I do not agree that alias.c needs to check the address for changes. In that case we're trying to determine if assigning a value to one memory reference can possibly change the value of another memory reference. Which is false for *all* read-only memory. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=20331
