                   uint16_t Version)

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLoc.h:122

Parameters

llvm::DWARFDataExtractor Data

uint16_t Version

¶void dumpRange(uint64_t StartOffset,
               uint64_t Size,
               llvm::raw_ostream& OS,
               const llvm::MCRegisterInfo* MRI,
               const llvm::DWARFObject& Obj,
               llvm::DIDumpOptions DumpOpts)

Description

Dump all location lists within the given range.

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLoc.h:130

Parameters

uint64_t StartOffset

uint64_t Size

llvm::raw_ostream& OS

const llvm::MCRegisterInfo* MRI

const llvm::DWARFObject& Obj

llvm::DIDumpOptions DumpOpts

¶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:135

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:125

Parameters

uint64_t* Offset

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