Function Documentation

bool for_each_index	(	tree *	addr_p,
		bool(*)(tree, tree *, void *)	cbck,
		void *	data
	)

Calls CBCK for each index in memory reference ADDR_P. There are two kinds situations handled; in each of these cases, the memory reference and DATA are passed to the callback:

Access to an array: ARRAY_{RANGE_}REF (base, index). In this case we also pass the pointer to the index to the callback.

Pointer dereference: INDIRECT_REF (addr). In this case we also pass the pointer to addr to the callback.

If the callback returns false, the whole search stops and false is returned. Otherwise the function returns true after traversing through the whole reference *ADDR_P.

If the component has varying offset, it behaves like index as well.
