can gdb support record of execution of function?

Hi,

Can gdb record the executed function names, but not only backtrace?
Such as:

main()
{
a();
b();
c();

breakpoint.
}

Then when it stops on breakpoint, I can issue a command to print it
has executed from a() to c(), which can't be got by backtrace.

Thanks.
Bin

No (at least not yet).

Usually this is done by using various logging techniques.

There is also a concept of "reverse debugging", which would allow
you to go back and see that c() was called, and go back further to
see that b() was also called, etc.

There is even a debugger that implements it: http://undo-software.com/

There is also talk of adding such functionality to gdb:
http://sourceware.org/gdb/news/reversible.html
but it's not there yet.
