Detailed Description

Remove Indirect Function Calls.

Function Documentation

bool function_is_type_compatible	(	bool	return_value_used,
		const code_typet &	call_type,
		const code_typet &	function_type,
		const namespacet &	ns
	)

Returns true iff call_type can be converted to produce a function call of the same type as function_type.

bool has_function_pointers ( const goto_functionst & goto_functions )

returns true iff any of the given goto functions has function calls via a function pointer

bool has_function_pointers ( const goto_modelt & goto_model )

returns true iff the given goto model has function calls via a function pointer

void remove_function_pointer	(	message_handlert &	message_handler,
		symbol_tablet &	symbol_table,
		goto_programt &	goto_program,
		const irep_idt &	function_id,
		goto_programt::targett	target,
		const std::unordered_set< symbol_exprt, irep_hash > &	functions
	)

Replace a call to a dynamic function at location target in the given goto-program by a case-split over a given set of functions.

Parameters

message_handler	Message handler to print warnings
symbol_table	Symbol table
goto_program	The goto program that contains target
function_id	Name of function containing the target
target	location with function call with function pointer
