I see the same test failing on trunk and the gcc 12 commit mentions it being a
backport.  The test is not in gcc 13 currently.

Yes, I stopped my backporting efforts when I became aware that it's failing on
ARM. I'll get to PPC ASAP and then continue with the backports.

--- Comment #3 from Matthias Kretz (Vir) <mkretz at gcc dot gnu.org> ---
I need help on how to reproduce this error. Your first lines say that the test
was compiled with `-maltivec -mpower9-vector -O2 -Wno-psabi` but that it only
happens with POWER 10? Do I need different compiler flags?

I have an idea why it might break, but then that doesn't explain why it doesn't
break for POWER 7/8/9 as well. Is there a chance that the __builtin_vec_cntm
signature changes incompatibly with POWER 10?

With -mcpu=power10 I see the issue. The problem has been there all the time and
only surfaced with this test. (It should also have shown on `make check-simd`
in libstdc++.)

You should backport to N-1 first, only then to N-2, etc.  Sanity is nice :-)

Next time :-)

Yup, you should never use -mpower9-vector and friends.  Such options are handy
*during development* but are heavily problematic later; they should never have
existed in mainline.

What is the actual problem here?  Or do you want to build up the suspense and
only show it in the patch you will send :-)

That was my intent. My workflow had not yet adapted to the existence of
releases/gcc-13. Fixed.

> never use -mpower9-vector and friends

I use -mpcu in my dejagnu boards (and the equivalent for 'check-simd'). IIUC
the -maltivec -mpower9-vector flags are added by
check_vect_support_and_set_flags in lib/target-supports.exp.

The problem was a branch that I apparently never tested (because the check-simd
testsuite wants to compile *and* run).

The `vec_cntm(__to_intrin(__kv), 1)` call uses an incorrect type for the first
argument. The compiler message isn't very helpful, though. Patch coming up.

This patch allows unsigned intrinsic types and calls vec_cntm correctly.

            * include/experimental/bits/simd.h (__intrinsic_type): If
            __ALTIVEC__ is defined, map gnu::vector_size types to their
            corresponding __vector T types without losing unsignedness of
            integer types. Also prefer long long over long.
            * include/experimental/bits/simd_ppc.h (_S_popcount): Cast mask
            object to the expected unsigned vector type.

--- Comment #13 from Matthias Kretz (Vir) <mkretz at gcc dot gnu.org> ---
Resolved on trunk and gcc-12 (for the other backports I reordered the commits
so that the test should never fail on bisect)
