Detailed Description

A helper containing a list of offsets computed for a Use.

Ideally this list should be strictly ascending, but we ensure that only when we actually translate the list of offsets to a RangeList.

merge()

bool llvm::AAPointerInfo::OffsetInfo::merge ( const OffsetInfo &  R )

inline

Copy offsets from R into the current list.

Ideally all lists should be strictly ascending, but we defer that to the actual use of the list. So we just blindly append here.
