bootstraps went fine.

Note the most important part of the command line is `-march=znver2 -O3` .

Reduced testcase

`-O3 -march=znver2 ` is enough with this testcase to reproduce it.

Hmm curious, does it work for you with --with-build-config='bootstrap-O3'
that's how I tested it before

vect_create_epilog_for_reduction needs to handle the case where the vectorizer
has picked a different exit than the main one.

fixes it. But would be good if I can reproduce the bootstrap issue. Will try
with provided options.

Will have a look. I'll try ignore the bootstrap failure and build userland
stuff now so we can get some other cases if any.

Did you have -march=<some ISA with good enough vector instructions> too? I
imagine bare '-O2' or '-O3' will be ok on amd64.

I built with the above configure args but also:
1. make -j32 -l32 'STAGE1_CFLAGS=-O3 -march=znver2 -pipe' 'BOOT_CFLAGS=-O3
-march=znver2 -pipe' ...
2. CFLAGS=... exported in the env

Re-confirmed after my fixes btw.

Yes I had to rerun my baseline after updating trunk. Will post patch once peak
finishes

Ok, the fix fixes the ICE but after rebasing to trunk I get a misscompile
during bootstrap which miscompiles the x86 backend.

This is likely related to https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113539
so tracking it down...

Ok, I've submitted the patch since the ICE and miscompare are unrelated.

I'll keep this ticket open in any case.  The miscompares didn't happen based on
commits from ~2 weeks ago, So this will give me a place to start.

Hopefully send a patch for those tomorrow.

    middle-end: fix epilog reductions when vector iters peeled [PR113364]

    This fixes a bug where vect_create_epilog_for_reduction does not handle the
    case where all exits are early exits.  In this case we should do like
induction
    handling code does and not have a main exit.

    This shows that some new miscompiles are happening (stage3 is likely
miscompiled)
    but that's unrelated to this patch and I'll look at it next.

    gcc/ChangeLog:

            PR tree-optimization/113364
            * tree-vect-loop.cc (vect_create_epilog_for_reduction): If all
exits all
            early exits then we must reduce from the first offset for all of
them.

    gcc/testsuite/ChangeLog:

            PR tree-optimization/113364
            * gcc.dg/vect/vect-early-break_107-pr113364.c: New test.

I'll continue with the miscompile in PR113539 which I think is a duplicate of
PR113467 which I'll verify now.
