--- Comment #1 from Oleg Endo <olegendo at gcc dot gnu.org> 2013-03-04 23:44:09 UTC --- Created attachment 29581 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=29581 A possible patch This patch seems to fix the problem, although tested only with 'make all-gcc'. BTW, the 'call-table' option for -mdiv= hasn't been documented either. Will fix that, too.
