Methods

¶DWARFLocationTable(llvm::DWARFDataExtractor Data)

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLoc.h:48

Parameters

llvm::DWARFDataExtractor Data

¶bool dumpLocationList(
    uint64_t* Offset,
    llvm::raw_ostream& OS,
    Optional<object::SectionedAddress> BaseAddr,
    const llvm::MCRegisterInfo* MRI,
    const llvm::DWARFObject& Obj,
    llvm::DWARFUnit* U,
    llvm::DIDumpOptions DumpOpts,
    unsigned int Indent) const

Description

Dump the location list at the given \p Offset. The function returns true iff it has successfully reched the end of the list. This means that one can attempt to parse another list after the current one (\p Offset will be updated to point past the end of the current list).

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLoc.h:64

Parameters

uint64_t* Offset

llvm::raw_ostream& OS

Optional<object::SectionedAddress> BaseAddr

const llvm::MCRegisterInfo* MRI

const llvm::DWARFObject& Obj

llvm::DWARFUnit* U

llvm::DIDumpOptions DumpOpts

unsigned int Indent

¶virtual 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:78

Parameters

const llvm::DWARFLocationEntry& Entry

llvm::raw_ostream& OS

unsigned int Indent

llvm::DIDumpOptions DumpOpts

const llvm::DWARFObject& Obj

¶llvm::Error visitAbsoluteLocationList(
    uint64_t Offset,
    Optional<object::SectionedAddress> BaseAddr,
    std::function<
        Optional<object::SectionedAddress>(
            uint32_t)> LookupAddr,
    function_ref<bool(
        Expected<llvm::DWARFLocationExpression>)>
        Callback) const

Declared at: llvm/include/llvm/DebugInfo/DWARF/DWARFDebugLoc.h:70

Parameters

uint64_t Offset

Optional<object::SectionedAddress> BaseAddr

std::function<Optional<object::SectionedAddress>( uint32_t)> LookupAddr

function_ref<bool( Expected<llvm::DWARFLocationExpression>)> Callback

¶virtual 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:56

Parameters

uint64_t* Offset

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