[CRIS] dwarf2 frame sniffer problem?

After getting the CRIS port into shape without the dwarf2 frame sniffer,
I hooked it in and found that basic stuff like next over a function call
no longer works. (More specifically, after stepping into the function,
gdb sets the breakpoint on the jump instruction itself, rather than at
the instruction after.)
I do get a complaint "During symbol reading, Incomplete CFI data;
unspecified registers at 0x000802f6." already by the time I get to
main(), where 802f6 is the first address in main(), which is where the
subroutine pointer is pushed. Although there is a comment in
dwarf2-frame.c explaining the complaint, I'm not sure how seriously I
should take it.
Thanks for any idea on what might be the cause or where to start digging.
