Re: [PATCH] Modify altivec-regs.exp testcase for AIX

Hi Ulrich,

Thank you for the reply. This was useful. While I was exploring other stuff related to this test case,

In the line gdb_continue_to_breakpoint "func2 breakpoint here, first time",


What does "first time" in the command gdb_continue_to_breakpoint here mean?? I can see a marker with name func2 breakpoint.. Does it mean continue to execute till that marker hits for the first time??

I am curious to know it. It will be helpful. Kindly let me know.

Have a nice day ahead.

Thanks and regards,
Aditya.

Hard-coding the fact that there need to be exactly
two "next" iterations is not really a good idea.

Usually this is done by placing a marker comment
in the source code at the target location, and
then using something like:

        gdb_breakpoint [gdb_get_line_number "func2 breakpoint here"]
        gdb_continue_to_breakpoint "func2 breakpoint here, first time"

(example from gdb.base/watchpoint.exp).

Bye,
Ulrich
