David Malcolm <dmalcolm at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |dmalcolm at gcc dot gnu.org --- Comment #1 from David Malcolm <dmalcolm at gcc dot gnu.org> --- Doesn't need the "-x c++". Started somewhere between r229464 (unaffected) and r229470 (affected); probably r229470. Running into this for gcc 8 due to: 2572 if (flag_checking) 2573 check_rtl (true); Is this valid code? My asm-syntax knowledge isn't strong.
