RE: [dsdp-dd-dev] GDB source lookup issues

Pawel and all,

The following may be helpful if you decide to implement the source
lookup that extracts the source information from modules. It's a part of
my discussion with Daniel Jacobowitz, I don't think he would mind me
posting it.

DJ: I believe that it will return all source files for all loaded
objects, no matter where they come from.
GDB doesn't know anything about shared libraries before they are loaded
- it's just too difficult to guess which copy of a shared library will
be loaded at runtime.  So I guess you would have to rerun the command
when libraries are loaded or unloaded.  We could add a command to list
source files for a particular shared object only.

DJ: I really dislike changing the behaviour of existing commands - we
don't know what front ends might be using.  If you don't mind I'll post
this issue to the GDB mailing list and copy you?

Subject: [dsdp-dd-dev] GDB source lookup issues

Hi Tobias and All,
I'm want to cross-post the following discussion from cdt-dev, which we
mentioned in this mornings DSF-GDB meeting:

It seems that Windows and cross platform development with GDB could be
much improved if this source lookup issue was addressed.  If after
fixing bug 219920 source lookup continues to be a problem for your use
cases, I recommend that you follow up and contribute to fixing this
issue in CDT.
