[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.
