Member Function Documentation

◆ contains()

bool DWARFVerifier::DieRangeInfo::contains ( const DieRangeInfo & RHS ) const

Return true if ranges in this object contains all ranges within RHS.

Definition at line 94 of file DWARFVerifier.cpp.

References DieRangeInfo(), and Ranges.

◆ insert() [1/2]

DWARFVerifier::DieRangeInfo::die_range_info_iterator DWARFVerifier::DieRangeInfo::insert ( const DieRangeInfo & RI )

Inserts the address range info.

If any of its ranges overlaps with a range in an existing range info, the range info is not added and an iterator to the overlapping range info. If a duplicate entry is attempted to be added, the duplicate range will not actually be added and the returned iterator will point to end().

This is used for finding overlapping children of the same DIE.

References Children, DieRangeInfo(), and Ranges.

◆ insert() [2/2]

std::optional< DWARFAddressRange > DWARFVerifier::DieRangeInfo::insert ( const DWARFAddressRange & R )

Inserts the address range.

If the range overlaps with an existing range, the range that it overlaps with will be returned and the two address ranges will be unioned together in "Ranges". If a duplicate entry is attempted to be added, the duplicate range will not actually be added and the returned iterator will point to end().

This is used for finding overlapping ranges in the DW_AT_ranges attribute of a DIE. It is also used as a set of address ranges that children address ranges must all be contained in.

◆ intersects()

bool DWARFVerifier::DieRangeInfo::intersects ( const DieRangeInfo & RHS ) const

Return true if any range in this object intersects with any range in RHS.

Identical ranges are not considered to be intersecting.
