I am using the following assembly language program (doNothingProg.s) for

main:
          pushq   %rbp        # save caller's frame pointer
          movq    %rsp, %rbp  # establish our frame pointer
          movl    $0, %eax    # return 0 to caller
          movq    %rbp, %rsp  # restore stack pointer
          popq    %rbp        # restore caller's frame pointer
          ret                 # back to caller

I want to set a breakpoint at the first instruction (pushq %rbp) so
students can see how the stack frame is created.
break *&main

Thank you for the response Adam.

Actually, break *main worked for me. (Or just br *main). I'm not in Linux right now, but I will double check next time I log in.

I found this by using info gdb and some looking around. As usual, the answer is in the documentation, as I often told my students. :-[
