IIUC, GDB can use this information when it is available and when the target requests the use of the DWARF frame sniffer. Look for calls to dwarf2_append_unwinders; this will tell you which targets are already capable of using it. Petr> Just go to binutils web and search for my name in the patch tracker. Petr> Oh wait, they do not have one. Maybe this is the reason they forgot to Petr> reply to my patches. You have to ping patches, not just for binutils but also gdb and gcc. It isn't a great system but it does have its advantages. One or two weeks after an initial submission, if there has been no answer, just send a ping message as a follow-up to your patch. Then do it every week. Tom
