            Bug ID: 96109
           Summary: gcc.dg/vect/slp-47.c etc. FAIL
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: rguenth at gcc dot gnu.org
  Target Milestone: ---
            Target: sparc-sun-solaris2.11, arm*-*-*, ia64-suse-linux-gnu

The new gcc.dg/vect/slp-47.c and gcc.dg/vect/slp-48.c tests FAIL on various
targets, e.g. sparc-sun-solaris2.11 (both 32 and 64-bit):

+FAIL: gcc.dg/vect/slp-47.c -flto -ffat-lto-objects  scan-tree-dump-times vect
"vectorizing stmts using SLP" 2
+FAIL: gcc.dg/vect/slp-47.c scan-tree-dump-times vect "vectorizing stmts using
SLP" 2
+FAIL: gcc.dg/vect/slp-48.c -flto -ffat-lto-objects  scan-tree-dump-times vect
"vectorizing stmts using SLP" 2
+FAIL: gcc.dg/vect/slp-48.c scan-tree-dump-times vect "vectorizing stmts using
SLP" 2

IIUC the failure on SPARC is due to

/vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/vect/slp-47.c:12:19: missed: 
 not vectorized: unsupported unaligned load: y[_5]
/vol/gcc/src/hg/master/local/gcc/testsuite/gcc.dg/vect/slp-47.c:20:17: missed: 
 not vectorized: unsupported unaligned load: y[_2]

I'm attaching the dump for reference.
