           Summary: Huge code size regression for all ARM configurations
           Product: gcc
           Version: 4.7.0
            Status: UNCONFIRMED
          Severity: major
          Priority: P3
         Component: rtl-optimization
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: rearnsha@gcc.gnu.org


SVN rev 171649 has caused huge code size (>3%) regressions on ARM, particularly
when compiling for Thumb2 or when using VFP.  This is equivalent to reversing
all the improvements of the last 2 years.

How to reproduce

Use the CSiBE benchmark. (ttp://www.inf.u-szeged.hu/csibe/)
