◆ FOR_EACH_BB_REVERSE_FN

◆ FOR_EACH_EDGE

#define FOR_EACH_EDGE ( EDGE,
ITER,
EDGE_VEC )
Value:
for ((ITER) = ei_start ((EDGE_VEC)); \
ei_cond ((ITER), &(EDGE)); \
ei_next (&(ITER)))
#define ei_start(iter)
Definition basic-block.h:378
This macro serves as a convenient way to iterate each edge in a
  vector of predecessor or successor edges.  It must not be used when
  an element might be removed during the traversal, otherwise
  elements will be missed.  Instead, use a for-loop like that shown
  in the following pseudo-code:

  FOR (ei = ei_start (bb->succs); (e = ei_safe_edge (ei)); )
    {
       IF (e != taken_edge)
         remove_edge (e);
       ELSE
         ei_next (&ei);
    }

◆ STATIC_ASSERT()

STATIC_ASSERT ( sizeof(rtl_bb_info) >=sizeof(gimple_bb_info) )
This ensures that struct gimple_bb_info is smaller than
struct rtl_bb_info, so that inlining the former into basic_block_def
is the better choice.
