           Summary: gcc.dg/vect/slp-multitypes-2.c execution failure
           Product: gcc
           Version: 4.6.0
            Status: UNCONFIRMED
          Keywords: wrong-code
          Severity: normal
          Priority: P3
         Component: rtl-optimization
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: ebotcazou@gcc.gnu.org
            Target: sparc-*-*


gcc.dg/vect/slp-multitypes-2.c fails on SPARC 32-bit with -mcpu=v9.  This has
nothing to do with vectorization per se but is apparently a reload problem:
