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 68 of file DWARFVerifier.cpp.

References 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.

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

Definition at line 53 of file DWARFVerifier.cpp.

References Ranges.

◆ insert() [2/2]

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".

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.

Definition at line 31 of file DWARFVerifier.cpp.

◆ intersects()

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

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

Definition at line 92 of file DWARFVerifier.cpp.

References Ranges.
