struct AddressRange

Declaration

struct AddressRange { /* full declaration omitted */ };

Description

A class that represents an address range. The range is specified using a start and an end address.

¶AddressRange(uint64_t S, uint64_t E)

Declared at: llvm/include/llvm/DebugInfo/GSYM/Range.h:36

Parameters

uint64_t S

uint64_t E

¶bool contains(uint64_t Addr) const

Declared at: llvm/include/llvm/DebugInfo/GSYM/Range.h:38

Parameters

uint64_t Addr

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

Description

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. @ {
