--- Comment #10 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Try https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69896#c8 ? I'm bootstrapping/regtesting it now on x86_64-linux and i686-linux, if it fixes even this testcase for you and you could bootstrap/regtest it on powerpc64*-linux, it would be appreciated.
