            Bug ID: 106228
           Summary: [12 regression] r13-1457-g10b502fb78351a causes
                    bootstrap failure
           Product: gcc
           Version: 13.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: bootstrap
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seurer at gcc dot gnu.org
  Target Milestone: ---

This may be related to PR106219 but the fix for that did not fix this.

This is causing a bootstrap failure on power 7 BE.  Note that there is no
problem on power 8 BE.

Can you possibly attach preprocessed source and the -v output?  I'm going to
try building a cross up to target libgfortran to reproduce.

It is still failing though it looks like at a slightly different point:

The configure options may be making a difference.  Here are the ones I was
using:  --enable-languages=c,fortran,c++ --with-cpu=power7 --disable-bootstrap
--enable-multilib

Ah, so -mcpu=power7 is needed as well.  I notice that the test case compiles
with no errors using -mcpu=power{8,9,10}.

There are some test cases that started ICEing with r13-1575-gcf3a120084e946
which fail at the same place in tree-vectorizer.cc:1032.  These fail on LE on
power 8/9/10.

OK, it's vect_setup_realignment called from

  tree offset = NULL_TREE;
  if ((alignment_support_scheme == dr_explicit_realign_optimized
       || alignment_support_scheme == dr_explicit_realign)
      && !compute_in_loop)
    {
      /* If we have different first_stmt_info, we can't set up realignment
         here, since we can't guarantee first_stmt_info DR has been
         initialized yet, use first_stmt_info_for_drptr DR by bumping the
         distance from first_stmt_info DR instead as below.  */
      if (!diff_first_stmt_info)

The following fixes that ICE.

The testsuite FAILs seem to use -mdejagnu-cpu=power7 so likely are the same.

    tree-optimization/106228 - fix vect_setup_realignment virtual SSA handling

    The following adds missing assignment of a virtual use operand to a
    created load to vect_setup_realignment which shows as bootstrap
    failure on powerpc64-linux and extra testsuite fails for targets
    when misaligned loads are not supported or not optimal.

            * tree-vect-data-refs.cc (vect_setup_realignment): Properly
            set a VUSE operand on the emitted load.

    vectorizing a loop.
