Build failure for sh64-unknown-linux-gnu

[Kaz Kojima]

Hi,

Mainline fails with a segfault on x86 cross sh64-unknown-linux-gnu
when building libraries.  The fault occurs at the first loop of
sbitmap.c:sbitmap_union_of_preds:

void
sbitmap_union_of_preds (sbitmap dst, sbitmap *src, int bb)
{
  basic_block b = BASIC_BLOCK (bb);
  unsigned int set_size = dst->size;
  edge e;
  unsigned ix;

  for (e = NULL, ix = 0; ix < EDGE_COUNT (b->preds); ix++)
    {
      if (e->src== ENTRY_BLOCK_PTR)
	continue;

Looks there is something missing.

Regards,
