Is stack back trace possible if compiled with -fomit-frame-pointer?

Is stack back trace possible if compiled with -fomit-frame-pointer?

[Xin Zhao]

Also, I might want to know whether it is common case that linux apps
are compiled with  -fomit-frame-pointer swtich?

Thanks!
Xin

This is the Linux KERNEL development list.

Not Linux USERSPACE development list.

Find an appropriate list and ask your question there please.

Thanks for your reply.

But I am looking for a tool or method to do stack backtrace
automatically, not debug manually.

The tool listed on http://www.aivosto.com/visustin.html can only
generate control flow from source code. But I need a control flow
generator that can generate control flow from binary codes. One
example is EEL (Executable Edit Library). But it only works for SPARC
machine, not PC. :(

As for the question about the kernel development list, I am developing
a kernel module that supports stack backtrace and can analyze user app
binaries to enforce security policies. So this is still related to
Kernel development. :)

Barring gentoo/LFS/DIY distros, where no such assertions can be made, the 
answer is probably "no". Most distros don't strip out a useful source of 
userspace debugging for the sake of 'speed'.
