Function Documentation

get_cover_config() [1/2]

cover_configt get_cover_config	(	const optionst &	options,
		const irep_idt &	main_function_id,
		const symbol_tablet &	symbol_table,
		message_handlert &	message_handler )

Include options that depend on the main function specified by the user.

Parameters

options	command-line options
main_function_id	symbol of the user-specified main program function
symbol_table	global symbol table
message_handler	used to log incorrect option specifications

Returns

a cover_configt on success, or null otherwise.

Definition at line 247 of file cover.cpp.
