Hi Bob,
what course u are teaching out there? give me the link to it, perhaps
i will learn there something useful as i am also a student.
I retired from teaching in 2004, but I keep my book, Introduction to
Computer Architecture, updated. It is available on my web site:
bob.cs.sonoma.edu
I checked info gdb. Under Source->Specify Location I found an entry for
`*ADDRESS'. Apparently, the *ADDRESS form is for C, C++, Java,
Objective-C, Fortran, minimal, and assembly. The *&ADDRESS' form is for
Pascal and Modula-2. However, it seems that gdb is forgiving between
these two forms. And, from my personal experience, this can differ
between versions and can change over time.

I am using the following assembly language program

movl $0, %eax # return 0 to caller

I want to set a breakpoint at the first instruction (pushq

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. :-[
