--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Created attachment 32702 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=32702&action=edit gcc49-pr60971.patch Agreed, but I'd say the bug is in the tailc pass then, it assumes conversion from QImode integer type with 8-bit precision to QImode bool type with 1-bit precision doesn't need any code, when that is not true, during expansion in those cases we apply REDUCE_BIT_FIELD.
