Methods

¶DWARFDebugLoc(llvm::DWARFDataExtractor Data)

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLoc.h:102

Parameters

llvm::DWARFDataExtractor Data

¶void dump(llvm::raw_ostream& OS,
          const llvm::MCRegisterInfo* RegInfo,
          const llvm::DWARFObject& Obj,
          llvm::DIDumpOptions DumpOpts,
          Optional<uint64_t> Offset) const

Description

Print the location lists found within the debug_loc section.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLoc.h:106

Parameters

llvm::raw_ostream& OS

const llvm::MCRegisterInfo* RegInfo

const llvm::DWARFObject& Obj

llvm::DIDumpOptions DumpOpts

Optional<uint64_t> Offset

¶void dumpRawEntry(
    const llvm::DWARFLocationEntry& Entry,
    llvm::raw_ostream& OS,
    unsigned int Indent,
    llvm::DIDumpOptions DumpOpts,
    const llvm::DWARFObject& Obj) const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLoc.h:115

Parameters

const llvm::DWARFLocationEntry& Entry

llvm::raw_ostream& OS

unsigned int Indent

llvm::DIDumpOptions DumpOpts

const llvm::DWARFObject& Obj

¶llvm::Error visitLocationList(
    uint64_t* Offset,
    function_ref<
        bool(const llvm::DWARFLocationEntry&)>
        Callback) const

Description

Call the user-provided callback for each entry (including the end-of-list entry) in the location list starting at \p Offset. The callback can return false to terminate the iteration early. Returns an error if it was unable to parse the entire location list correctly. Upon successful termination\p Offset will be updated point past the end of the list.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLoc.h:110

Parameters

uint64_t* Offset

function_ref<bool( const llvm::DWARFLocationEntry&)> Callback
