Function Documentation

static bool CheckAsmLValue	(	const Expr *	E,
		Sema &	S
	)		[static]

CheckAsmLValue - GNU C has an extremely ugly extension whereby they silently ignore "noop" casts in places where an lvalue is required by an inline asm. We emulate this behavior when -fheinous-gnu-extensions is specified, but provide a strong guidance to not use it.

This method checks to see if the argument is an acceptable l-value and returns false if it is a case we can handle.
