◆ getUnique()

const RangeTy & llvm::AAPointerInfo::RangeList::getUnique ( ) const
inline

Return the unique range, assuming it exists.

References assert(), isUnique(), and Ranges.

◆ insert() [1/2]

std::pair< iterator, bool > llvm::AAPointerInfo::RangeList::insert ( const RangeTy & R)
inline

Insert the given range R, maintaining sorted order.

Returns
The place of insertion and true iff anything changed.

Definition at line 5969 of file Attributor.h.

References insert(), and Ranges.

◆ insert() [2/2]

std::pair< iterator, bool > llvm::AAPointerInfo::RangeList::insert ( iterator Pos,
const RangeTy & R )
inline

Insert R at the given iterator Pos, and merge if necessary.

This assumes that all ranges before Pos are LessThan R, and then maintains the sorted order for the suffix list.

Returns
The place of insertion and true iff anything changed.

References Ranges.

Referenced by addToAllOffsets(), and isUnknown().

References Ranges.

Referenced by getUnique().

◆ isUnknown()

bool llvm::AAPointerInfo::RangeList::isUnknown ( ) const
inline

Return true iff the list contains an unknown range.

Referenced by addToAllOffsets(), insert(), and merge().

◆ merge()

bool llvm::AAPointerInfo::RangeList::merge ( const RangeList & RHS)
inline

Merge the ranges in RHS into the current ranges.

  • Merging a list of unknown ranges makes the current list unknown.
  • Ranges with the same offset are merged according to RangeTy::operator&
    Returns
    true if the current RangeList changed.
