             Bug #: 54150
           Summary: [4.8 Regression] gimple dumps no longer honor -blocks
    Classification: Unclassified
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
        AssignedTo: unassig...@gcc.gnu.org
        ReportedBy: rgue...@gcc.gnu.org
                CC: stevenb....@gmail.com


gimple dumps now by default dump a RTL-like bb header:

;;   basic block 2, loop depth 0
;;    pred:       ENTRY
  D.1602_12 = (sizetype) m_5(D);
  D.1603_13 = D.1602_12 * 4;
  goto <bb 6>;

;;    succ:       6

previously TDF_blocks was required for that (and I'd like to have that back).
Also notice the extra newline before ;; succ: which seems to be caused by
pp_base_flush which does not only flush but also prints a newline, and that
independent on whether pp_needs_newline is set.

That said, the tree dumps still look remarkably ugly by default now.
