Function Documentation

remove_exceptions() [1/2]

void remove_exceptions	(	goto_programt &	goto_program,
		symbol_table_baset &	symbol_table,
		message_handlert &	message_handler,
		remove_exceptions_typest	type
	)

removes throws/CATCH-POP/CATCH-PUSH from a single GOTO program, replacing them with explicit exception propagation.

Note this is somewhat less accurate than the whole-goto-model version, because we can't inspect other functions to determine whether they throw or not, and therefore must assume they do and always introduce post-call exception dispatch.

Parameters

goto_program	program to remove exceptions from
symbol_table	global symbol table. The @inflight_exception global may be added if not already present. It will not be initialised; that is the caller's responsibility.
message_handler	logging output
type	specifies whether instanceof operations generated by this pass should be lowered to class-identifier comparisons (using remove_instanceof).
