Member Function Documentation

lower_instanceof() [1/3]

bool remove_instanceoft::lower_instanceof ( const irep_idt &  function_identifier, exprt &  expr, goto_programt &  goto_program, goto_programt::targett  this_inst  )

protected

Replaces an expression like e instanceof A with e.

@class_identifier == "A" or a big-or of similar expressions if we know of subtypes that also satisfy the given test.

Parameters

function_identifier	name of the goto function goto_program
expr	Expression to lower (the code or the guard of an instruction)
goto_program	program the expression belongs to
this_inst	instruction the expression is found at

Returns

true if any instanceof instructionw was replaced

Definition at line 101 of file remove_instanceof.cpp.

lower_instanceof() [2/3]

bool remove_instanceoft::lower_instanceof	(	const irep_idt &	function_identifier,
		goto_programt &	goto_program
	)

Replace every instanceof in the passed function body with an explicit class-identifier test.

Extra auxiliary variables may be introduced into symbol_table.

Parameters

function_identifier	name of the goto function goto_program
goto_program	The function body to work on.

Returns

true if one or more instanceof expressions have been replaced

Definition at line 278 of file remove_instanceof.cpp.

lower_instanceof() [3/3]

bool remove_instanceoft::lower_instanceof	(	const irep_idt &	function_identifier,
		goto_programt &	goto_program,
		goto_programt::targett	target
	)

Replaces expressions like e instanceof A with e.

@class_identifier == "A" or a big-or of similar expressions if we know of subtypes that also satisfy the given test. Does this for the code or guard at a specific instruction.

Parameters

function_identifier	name of the goto function goto_program
goto_program	program to process
target	instruction to check for instanceof expressions

Returns

true if an instanceof has been replaced

Definition at line 239 of file remove_instanceof.cpp.
