RE: [cdt-dev] [DSF-GDB] Pending breakpoint support

[Marc Khouzam <marc.khouzam@xxxxxxxxxxxx>]

I have committed the pending breakpoint solution for DSF-GDB.
It works for GDB >= 6.8

But now that we set pending breakpoints automatically, I was 
thinking that we may want this to also work when the user 
sets a breakpoint from the gdb console.

We can do this by using "set breakpoint pending on".

Note that CDI does not do this.  Consequently, if a user sets
a breakpoint in a dll using the console, it will not get set
if the dll is not loaded yet.

Anyone think this is a good idea?

Thanks

Marc
