Function &	set_address (uint64_t addr)
	Set the address of this function by defining DW_AT_entry_pc
Function &	set_low_high (uint64_t low, uint64_t high)
	Set the upper and lower bound addresses for this function. This assumes that the function is contiguous between low and high.
Function &	set_ranges (const std::vector< range_t > &ranges)
	Set the ranges of addresses owned by the implementation of this function by setting the DW_AT_ranges attribute.
Function &	set_external ()
	Set the function as external by defining DW_AT_external to true. This means that the function is imported by the current compilation unit.
Function &	set_return_type (const Type &type)
	Set the return type of this function.
std::unique_ptr< Parameter >	add_parameter (const std::string &name, const Type &type)
	Add a parameter to the current function.
std::unique_ptr< Variable >	create_stack_variable (const std::string &name)
	Create a stack-based variable owned by the current function.
std::unique_ptr< LexicalBlock >	add_lexical_block (uint64_t start, uint64_t end)
	Add a lexical block with the given range.
std::unique_ptr< Label >	add_label (uint64_t addr, const std::string &label)
	Add a label at the given address.

Member Function Documentation

add_label()

std::unique_ptr< Label > LIEF::dwarf::editor::Function::add_label	(	uint64_t	addr,
		const std::string &	label )

Add a label at the given address.

add_lexical_block()

std::unique_ptr< LexicalBlock > LIEF::dwarf::editor::Function::add_lexical_block	(	uint64_t	start,
		uint64_t	end )

Add a lexical block with the given range.

add_parameter()

std::unique_ptr< Parameter > LIEF::dwarf::editor::Function::add_parameter	(	const std::string &	name,
		const Type &	type )

Add a parameter to the current function.

create_stack_variable()

std::unique_ptr< Variable > LIEF::dwarf::editor::Function::create_stack_variable

(

const std::string &

name

)

Create a stack-based variable owned by the current function.

set_address()

Function & LIEF::dwarf::editor::Function::set_address

(

uint64_t

addr

)

Set the address of this function by defining DW_AT_entry_pc

set_external()

Function & LIEF::dwarf::editor::Function::set_external

(

)

Set the function as external by defining DW_AT_external to true. This means that the function is imported by the current compilation unit.

set_low_high()

Function & LIEF::dwarf::editor::Function::set_low_high	(	uint64_t	low,
		uint64_t	high )

Set the upper and lower bound addresses for this function. This assumes that the function is contiguous between low and high.

Underneath, the function defines DW_AT_low_pc and DW_AT_high_pc

set_ranges()

Function & LIEF::dwarf::editor::Function::set_ranges

(

const std::vector< range_t > &

ranges

)

Set the ranges of addresses owned by the implementation of this function by setting the DW_AT_ranges attribute.

This setter should be used for non-contiguous function.

set_return_type()

Function & LIEF::dwarf::editor::Function::set_return_type

(

const Type &

type

)

Set the return type of this function.
