            Bug ID: 84005
           Summary: [8 regression] gcc.dg/vect/bb-slp-1.c etc. FAIL
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: tree-optimization
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
  Target Milestone: ---
            Target: sparc*-*-*, ia64-*-*, powerpc64-*-*

Between 20170702 (r249882) and 20170703 (r249926), gcc.dg/vect/bb-slp-1.c
started
to FAIL:

I'm seeing this on sparc-sun-solaris2.*, but according to gcc-testresults
postings
it also occurs on IA-64 and PowerPC.
