Detailed Description

AddressesMap represents information about valid addresses used by debug information.

Valid addresses are those which points to live code sections. i.e. relocations for these addresses point into sections which would be/are placed into resulting binary.

Member Function Documentation

applyValidRelocs()

virtual bool llvm::AddressesMap::applyValidRelocs ( MutableArrayRef< char >  Data, uint64_t  BaseOffset, bool  IsLittleEndian  )

pure virtual

Apply the valid relocations to the buffer Data, taking into account that Data is at BaseOffset in the .debug_info section.

Returns

true whether any reloc has been applied.

clear()

virtual void llvm::AddressesMap::clear ( )

pure virtual

Erases all data.

getValidAddressRanges()

virtual RangesTy & llvm::AddressesMap::getValidAddressRanges ( )

pure virtual

Returns all valid functions address ranges(i.e., those ranges which points to sections with code).

hasValidRelocs()

virtual bool llvm::AddressesMap::hasValidRelocs ( )

pure virtual

Checks that there are valid relocations against a .debug_info section.

isLiveSubprogram()

virtual bool llvm::AddressesMap::isLiveSubprogram ( const DWARFDie &  DIE, CompileUnit::DIEInfo &  Info  )

pure virtual

Checks that the specified subprogram DIE references live code section.

Allowed kind of input die: DW_TAG_subprogram, DW_TAG_label.

Returns

true and sets Info.InDebugMap if it is the case.

isLiveVariable()

virtual bool llvm::AddressesMap::isLiveVariable ( const DWARFDie &  DIE, CompileUnit::DIEInfo &  Info  )

pure virtual

Checks that the specified variable DIE references live code section.

Allowed kind of input die: DW_TAG_variable, DW_TAG_constant.

Returns

true and sets Info.InDebugMap if it is the case.
