GDB support for 'Run to Line'

GDB support for 'Run to Line'

[Marc Khouzam]

Hi,

I'm trying to figure out if GDB has support for the 'Run to Line'
feature
of Eclipse, where the user selects a line and the inferior resumes until
that
line.

GDB's 'until' does not seem to be the right choice since it only stops
if the
location is in the same frame.

GDB's 'advance' is better, but it stops if the current frame exists.

Anything else that I could use to 'run to line' anywhere in the program?

Thanks

Isn't this just tbreak + continue?

If it was a question and not a feature request then:

cat >>~/.gdbinit <<EOH
define runto
	tbreak $arg0
	cont
end
EOH

Problem is that if another breakpoint is hit first, this temporary one
will remain and will hit later, unexpectedly to the user.  I would have to remove
that temp bp myself in that case.
 
Of course, one way to do run to line is to disable all other bps until that line is reached.
This is a preference in Eclipse, so I have to support both ways.
Now, with non-stop, I don't think disabling all bps (even for a short while) is a good 
idea anymore.  I would need to disable all bps for a particular thread only.  I don't think
GDB allows me to do this.  This was doing to be a future question of mine on the list :-)
 
But if tbreak + continue + cleanup is my best option, that is what I'll look into.
 
Thanks
