behavior of finish within command set in gdb5.0

behavior of finish within command set in gdb5.0

[Smita]

I am trying to specify command set for a breakpoint, like this:

break funtion_name
commands
 finish
continue
end

1. In gdb4.17 (netbsd), it results in a behavior where gdb stops at the
function, prints the return value, and contiues.
2. In gdb5.0 (netbsd), it stops at the function, prints the return value,
and then stops at the gdb prompt, expecting input from the user.

What's the correct behavior of finish? (1) or (2)?

Thanks
Smita

The correct behavior, that is the behavior documented in the GDB
documentation, is (2). The documentation also explains why they chose
(2).

command?

how to find function size?

[Smita]

Hi,
 I was wondering if there is a way to determine the size of a function
given the symbol table?

commands after finish

[Smita]

Hi,
 Is there a way to specify commands when finish stops at the return
address? for example:

break function1
finish
end

Q1: Is there a way to specify commands when fucntion1 returns after finish
command?
Q2: If function1 calls another function then the finish command for
function won't take effect. Am I right?

Thanks
Smita

breakpoint at function return

[Smita]

Hi,
 Is there a way to put a breakpoint at a function's return point
"statically"?
 I know I can put a breakpoint at *(*(*$r1+4)). But $r1 can
be determined only "dynamically" when the function is called.

Thanks a lot!
