Detailed Description

Remove function returns.

Definition in file remove_returns.h.

Macro Definition Documentation

◆ RETURN_VALUE_SUFFIX

#define RETURN_VALUE_SUFFIX "#return_value"

Definition at line 21 of file remove_returns.h.

Typedef Documentation

◆ function_is_stubt

typedef std::function<bool(const irep_idt &)> function_is_stubt

Definition at line 34 of file remove_returns.h.

Function Documentation

◆ original_return_type()

code_typet original_return_type	(	const symbol_table_baset &	symbol_table,
		const irep_idt &	function_id
	)

Get code type of a function that has had remove_returns run upon it.

Parameters

symbol_table	global symbol table
function_id	function to get the type of

Returns: the function's type with its return_type() restored to its original value

Definition at line 300 of file remove_returns.cpp.

◆ remove_returns() [1/3]

void remove_returns	(	symbol_table_baset &	,
		goto_functionst &
	)

removes returns

Definition at line 261 of file remove_returns.cpp.

◆ remove_returns() [2/3]

void remove_returns	(	goto_model_functiont &	goto_model_function,
		function_is_stubt	function_is_stub
	)

Removes returns from a single function.

Only usable with Java programs at the moment; to use it with other languages, they must annotate their stub functions with ID_C_incomplete as currently done in java_bytecode_convert_method.cpp.

This will generate #return_value variables, if not already present, for both the function being altered and any callees.

Parameters

goto_model_function	function to transform
function_is_stub	function that will be used to test whether a given callee has been or will be given a body. It should return true if so, or false if the function will remain a bodyless stub.

Definition at line 280 of file remove_returns.cpp.

◆ remove_returns() [3/3]

void remove_returns ( goto_modelt & )

removes returns

Definition at line 289 of file remove_returns.cpp.

◆ restore_returns() [1/2]

void restore_returns	(	symbol_table_baset &	,
		goto_functionst &
	)

◆ restore_returns() [2/2]

void restore_returns ( goto_modelt & )

restores return statements
