Content-Type: text/plain; charset=us-ascii; format=flowed Content-Transfer-Encoding: 7bit X-SW-Source: 2004-03/txt/msg00239.txt.bz2 Message-ID: <20040319000900.JGtsHITDuuk5WBNeH8IshWq2qjse_VLIkSs7LzbYJf4@z> 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. -- Orjan Friberg Axis Communications
