--- Comment #4 from Nick Clifton <nickc at redhat dot com> --- Created attachment 35123 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=35123&action=edit Disable the generation of real_jump insns This patch works around the problem by disabling the generation of the real_jump insns. I am not enough of a C6X expert to determine why these instruction patterns are not working, but they are definitely part of the problem.
