whether this is an alias as opposed to ifunc attribute.

◆ validate_attr_args()

bool validate_attr_args	(	tree	node[2],

		tree	newargs[2] )

extern

Shared helpers used by the handlers.

Given a pair of NODEs for arbitrary DECLs or TYPEs, validate one or
two integral or string attribute arguments NEWARGS to be applied to
NODE[0] for the absence of conflicts with the same attribute arguments
already applied to NODE[1]. Issue a warning for conflicts and return
false.  Otherwise, when no conflicts are found, return true.
