Re: Making "info thread" sane

> First, the objective is to get something like what "info thread" does but with a frame that is outside of the switch code (which may mean  several frames up the stack).  I was considering a macro that would do a silent info thread followed by a loop on each discovered thread.  In your message yesterday you suggested something like:

"try" isn't seen cos the patch is sitting in the bug database :-(

I mentioned "try" as without it the command will abort on the first 
error (e.g., corrupt stack for bad memory access).

Can you post the output so we can see exactly what you mean here?

> Nice, would be the ability to print the final up result without doing the down first.  In fact this is really needed if it turns out that we are at the first frame which would be the case for the current thread.  Is that a command I missed?

You mean an abbreviated "info frame"?  Yes, using "up" to get that 
output isn't right.

What "info remote-process" command?
