Debugging frameless code

[Nicolas.Thery@Symbian.com]

Hi,

GDB documentation states that gdb has limited ability to deal with code
compiled without frame pointer.

Does this limitation applies to every version of gdb and every kind of
binary/debug format?

To be more precise, is it possible to dump stack backtrace for frameless
code using a recent version of gdb and elf/dwarf2 (and gcc as the
compiler)?

I've been told that dwarf2 includes information that can help a debugger in
such a case, but I don't know whether gcc actually emits these information
and whether gdb is able to use them.

Thanks in advance
