            Bug ID: 88369
           Summary: [9 regression] g++.dg/vect/pr33426-ivdep.cc etc. FAIL
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: dmalcolm at gcc dot gnu.org, schwab at gcc dot gnu.org
  Target Milestone: ---
            Target: sparc*-sun-solaris2.*, ia64-suse-linux-gnu

Between 20180928 (r264685) and 20180929 (r264715), two tests started to regress
on SPARC and IA-64:
+FAIL: g++.dg/vect/pr33426-ivdep-2.cc  -std=c++11 (test for excess errors)
+FAIL: g++.dg/vect/pr33426-ivdep-2.cc  -std=c++14 (test for excess errors)
+FAIL: g++.dg/vect/pr33426-ivdep-2.cc  -std=c++98 (test for excess errors)

Excess errors:
/vol/gcc/src/hg/trunk/local/gcc/testsuite/g++.dg/vect/pr33426-ivdep-2.cc:12:3:
optimized:  loop versioned for vectorization to enhance alignment
