--- Comment #5 from DJ Delorie <dj at redhat dot com> 2011-01-18 01:46:00 UTC --- Created attachment 23014 --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=23014 alternate patch Alternate patch. The v850.md patch tests frame_related, which is set for REGS only to indicate that the value is a pointer, which "fixed" this bug only by coincidence. I think what's happening is that the v850 backend is generating a BB that starts with a label, so fixup_sched_groups uses prev_nonnote_nondebug_insn() and finds the label. However, the functions it calls expects only an INSN. This patch adds a check for an INSN, to avoid adding deps on labels.
