llvm::DWARFDataExtractorSimple::getEncodedPointer

Extract a DWARF‐encoded pointer at Offset using Encoding.

Synopsis

Declared in <llvm/DebugInfo/DWARF/LowLevel/DWARFDataExtractorSimple.h>

std::optional<uint64_t>
getEncodedPointer(
    uint64_t* Offset,
    uint8_t Encoding,
    uint64_t PCRelOffset) const;

Description

There is a DWARF encoding that uses a PC‐relative adjustment. For these values, PCRelOffset is used to fix them, which should reflect the absolute address of this pointer.

Return Value

The decoded pointer value, or std::nullopt if omitted or unsupported.

Parameters

Name

Description

Offset

Offset into the data; advanced past the pointer on success.

Encoding

DWARF pointer encoding (DW_EH_PE_*).

PCRelOffset

Absolute address used to fix up PC‐relative encodings.
