Member Function Documentation

contains()

bool llvm::gsym::AddressRange::contains ( uint64_t  Addr ) const

inline

Definition at line 39 of file Range.h.

decode()

void AddressRange::decode	(	DataExtractor &	Data,
		uint64_t	BaseAddr,
		uint64_t &	Offset
	)

AddressRange objects are encoded and decoded to be relative to a base address.

This will be the FunctionInfo's start address if the AddressRange is directly contained in a FunctionInfo, or a base address of the containing parent AddressRange or AddressRanges. This allows address ranges to be efficiently encoded using ULEB128 encodings as we encode the offset and size of each range instead of full addresses. This also makes encoded addresses easy to relocate as we just need to relocate one base address.
