ALL_BOUNDS

FOR_EACH_SUBRTX

#define FOR_EACH_SUBRTX	(		ITER,
			ARRAY,
			X,
			TYPE )

Value:

  for (subrtx_iterator ITER (ARRAY, X, TYPE##_BOUNDS); !ITER.at_end (); \
       ITER.next ())

Use ITER to iterate over const_rtx X and its recursive subrtxes,
using subrtx_iterator::array ARRAY as the storage for the worklist.
ARRAY can be reused for multiple consecutive iterations but shouldn't
be shared by two concurrent iterations.  TYPE is ALL if all subrtxes
are of interest or NONCONST if it is safe to ignore subrtxes of
constants.

FOR_EACH_SUBRTX_PTR

#define FOR_EACH_SUBRTX_PTR	(		ITER,
			ARRAY,
			X,
			TYPE )

Value:

  for (subrtx_ptr_iterator ITER (ARRAY, X, TYPE##_BOUNDS); !ITER.at_end (); \
       ITER.next ())

Like FOR_EACH_SUBRTX, but iterate over subrtx pointers of rtx pointer X.
For example, if X is &PATTERN (insn) and the pattern is a SET, iterate
over &PATTERN (insn), &SET_DEST (PATTERN (insn)), etc.

FOR_EACH_SUBRTX_VAR

			ARRAY,

Value:

  for (subrtx_var_iterator ITER (ARRAY, X, TYPE##_BOUNDS); !ITER.at_end (); \
       ITER.next ())

Like FOR_EACH_SUBRTX, but iterate over subrtxes of an rtx X.
