...ich the pointer is derived from. Take the following example. I know %0 = load i32, i32* %a, align 4, !tbaa !1 and store i32 %i.02, i32* %b, align 4, !tbaa !6 do not alias as their metadata !1 = !{!2, !3, i64 0} and !6 = !{!7, !3, i64 0} tell me that they are derived from different (incompatible) basetypes. However i can also walk up the IR chain and find out %a is point to basetype object of struct A and %b pointing to basetype object of struct B. Maybe, the metadata simplified the TBAA pass ?
