--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
CFG looks as follows:

Released 0 names, 0.00%, removed 0 holes
main ()
{
  int b;

  <bb 2> :
  b_2 = 0;
  goto <bb 4>; [INV]

  <bb 3> :
  b_3 = b_1 + 1;

  <bb 4> :
  # b_1 = PHI <b_2(2), b_3(3)>
  if (b_1 <= 0)
    goto <bb 3>; [INV]
  else
    goto <bb 5>; [INV]

  <bb 5> :
  return;
}

and line is mapped to:

pr83434.gcno:    01450000:  11:LINES
pr83434.gcno:                  block 2:`pr83434.c':1, 3, 4
pr85199.gcno:    01450000:   9:LINES
pr85199.gcno:                  block 4:`pr85199.c':4

which is slightly misleading. Setting low priority.
