◆ try_evaluate_pointer_comparison()

static std::optional< exprt > try_evaluate_pointer_comparison	(	const irep_idt &	operation,
		const symbol_exprt &	symbol_expr,
		const exprt &	other_operand,

	)

static

Try to evaluate a simple pointer comparison.

Parameters

operation	ID_equal or ID_not_equal
symbol_expr	The symbol expression in the condition
other_operand	The other expression in the condition; we only support an address of expression, a typecast of an address of expression or a null pointer, and return an empty std::optional in all other cases
value_set	The value-set for looking up what the symbol can point to
language_mode	The language mode
ns	A namespace

Returns: If we were able to evaluate the condition as true or false then we return that, otherwise we return an empty std::optional
