             Bug #: 14479
           Summary: no way to request gdb to load separate debuginfo
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: symtab
        AssignedTo: unassigned@sourceware.org
        ReportedBy: tromey@redhat.com
    Classification: Unclassified


I was debugging a program.
gdb suggested I install some separate debuginfo packages
(I think this is a Fedora extension -- but it doesn't matter
since the problem here is generic).
I wanted one of these, so in a separate window I ran debuginfo-install.

At this point I wanted to tell gdb to try again to load the
separate debuginfo.  However, there's no convenient way to do this.
"sharedlibrary" doesn't work.
"add-symbol-file" might work but it is a pain.

I think the simplest would be to make "sharedlibrary" do it.

For completeness, "sharedlibrary" might not, but I guess
"nosharedlibrary+sharedlibrary" would work.

Yeah, I thought of that (much) later.
It seems obscure though.

I happened to try this today.
The combo "nosharedlibrary" + "sharedlibrary .*" did work.
However, it made gdb forget my selected frame.
Perhaps a more targeted command could try harder to preserve
the selected frame.
