--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 47062 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=47062&action=edit gcc10-pr92140-wip.patch Slightly extended untested patch, which handles all the cases in the testcase at the start of the file. Originally reported tst3 still unhandled though.
