Debug Info

PDB and DWARF shares similar traits which are abstracted by the following classes:

C++

DebugInfo

class DebugInfo

This class provides a generic interface for accessing debug information from different formats such as DWARF and PDB.

Users can use this interface to access high-level debug features like resolving function addresses.

See: LIEF::pdb::DebugInfo, LIEF::dwarf::DebugInfo

Subclassed by LIEF::dwarf::DebugInfo, LIEF::pdb::DebugInfo

Public Types

enum class FORMAT

Values:

enumerator UNKNOWN = 0
enumerator DWARF
enumerator PDB

Public Functions

DebugInfo(std::unique_ptr<details::DebugInfo> impl)
virtual ~DebugInfo()
inline virtual FORMAT format() const
template<class T>
inline const T *as() const

This function can be used to down cast a DebugInfo instance:

std::unique_ptr<LIEF::Instruction> dbg = bin->debug_info();
if (const auto* dwarf = inst->as<LIEF::dwarf::DebugInfo>()) {
  dwarf->find_function("main");
}
virtual optional<uint64_t> find_function_address(const std::string &name) const = 0

Attempt to resolve the address of the function specified by name.

Friends

friend class Binary

debug_location_t

struct debug_location_t

This structure holds a debug location (source filename & line).

Public Members

std::string file
uint64_t line = 0

Python

DebugInfo

class lief.DebugInfo

Bases: object

This class provides a generic interface for accessing debug information from different formats such as DWARF and PDB.

Users can use this interface to access high-level debug features like resolving function addresses.

See: DebugInfo, lief.dwarf.DebugInfo

class FORMAT(*values)

Bases: Enum

DWARF = 1
PDB = 2
UNKNOWN = 0
from_value(arg: int) → lief.DebugInfo.FORMAT = <nanobind.nb_func object>
find_function_address(self, name: str) → int | None

Attempt to resolve the address of the function specified by name.

property format → lief.DebugInfo.FORMAT

The actual debug format (PDB/DWARF)

debug_location_t

class lief.debug_location_t

Bases: object

property file → str
property line → int
