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

.text
.globl main
.type main, @function
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. :-[
