Member Function Documentation

◆ address()

result< uint64_t > LIEF::dwarf::Function::address ( ) const

Return the address of the function (DW_AT_entry_pc or DW_AT_low_pc).

◆ debug_location()

debug_location_t LIEF::dwarf::Function::debug_location ( ) const

Original source code location.

◆ is_artificial()

bool LIEF::dwarf::Function::is_artificial ( ) const

Whether this function is created by the compiler and not present in the original source code.

◆ is_external()

bool LIEF::dwarf::Function::is_external ( ) const

Whether the function is defined outside the current compilation unit (DW_AT_external).

◆ linkage_name()

std::string LIEF::dwarf::Function::linkage_name ( ) const

The name of the function which is used for linking (DW_AT_linkage_name).

This name differs from name() as it is usually mangled. The function return an empty string if the linkage name is not available.

◆ name()

std::string LIEF::dwarf::Function::name ( ) const

The name of the function (DW_AT_name)

◆ parameters()

parameters_t LIEF::dwarf::Function::parameters ( ) const

Return the function's parameters (including any template parameter)

◆ ranges()

std::vector< range_t > LIEF::dwarf::Function::ranges ( ) const

Ranges of virtual addresses owned by this function.

◆ scope()

std::unique_ptr< Scope > LIEF::dwarf::Function::scope ( ) const

Return the scope in which this function is defined.

◆ size()

uint64_t LIEF::dwarf::Function::size ( ) const

Return the size taken by this function in the binary.

◆ thrown_types()

thrown_types_t LIEF::dwarf::Function::thrown_types ( ) const

List of exceptions (types) that can be thrown by the function.

For instance, given this Swift code:

func summarize(_ ratings: [Int]) throws(StatisticsError) {
// ...
}

thrown_types() returns one element associated with the Type: StatisticsError.

◆ type()

std::unique_ptr< Type > LIEF::dwarf::Function::type ( ) const

Return the dwarf::Type associated with the return type of this function.

◆ variables()

vars_it LIEF::dwarf::Function::variables ( ) const

Return an iterator of variables (DW_TAG_variable) defined within the scope of this function. This includes regular stack-based variables as well as static ones.
