--- Comment #6 from Segher Boessenkool <segher at gcc dot gnu.org> --- (In reply to Matthias Kretz (Vir) from comment #4) > 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++.) 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 :-)
