Member Function Documentation

◆ addUnit()

DWARFUnit * DWARFUnitVector::addUnit ( std::unique_ptr< DWARFUnit > Unit )

Add an existing DWARFUnit to this UnitVector.

This is used by the DWARF verifier to process unit separately.

Definition at line 121 of file DWARFUnit.cpp.

References llvm::sys::path::begin(), llvm::sys::path::end(), I, and llvm::upper_bound().

◆ addUnitsForDWOSection()

void DWARFUnitVector::addUnitsForDWOSection	(	DWARFContext &	C,
		const DWARFSection &	DWOSection,
		DWARFSectionKind	SectionKind,
		bool	Lazy = `false`
	)

Read units from a .debug_info.dwo or .debug_types.dwo section.

Calls made before finishedInfoUnits() are assumed to be for .debug_info.dwo sections, calls after finishedInfoUnits() are for .debug_types.dwo sections. Caller must not mix calls to addUnitsForSection and addUnitsForDWOSection.

◆ addUnitsForSection()

void DWARFUnitVector::addUnitsForSection	(	DWARFContext &	C,

		DWARFSectionKind	SectionKind
	)

Read units from a .debug_info or .debug_types section.

Calls made before finishedInfoUnits() are assumed to be for .debug_info sections, calls after finishedInfoUnits() are for .debug_types sections. Caller must not mix calls to addUnitsForSection and addUnitsForDWOSection.
