Stripped files

Stripped files

[Stephen & Linda Smith]

We've had a couple of discussions about stripped files here lately and 
so I want to know a couple of things from GDB's point of view.

Am I breaking any assumptions in the GDB code if the code running on a 
remote target is stripped and the code that GDB loads on the host has 
the symbolic information?  In other words is GDB likely to get confused 
by this situation?

If the situation in the above paragraph isn't a problem, would it be a 
good idea for GDB to sniff for the file with the symbolic information 
via an default extension.  For example the file that would be on the 
remote target would be something like libfoo.so and the file that that 
gdb would look for first on the host system would be 
libfoo.so-withsymbols and then fi that didn't exist it would look for 
libfoo.so.

What do you think of that?

No, this is normal.

The solution we've used for this before is .gnu_debuglink (see the GDB
and binutils manuals for more about that).  You can also use
sysroot / solib-search-path if the debug symbol file has the same name as the
target file.

Is there currently support for this in GDB both for the main executable 
and for any shared libraries (via the solib interface)?

Or does something need to be written?

It should already work.
