I noticed the functions declared in cli-dump.h aren't used anywhere
outside cli-dump.c.
The original patch that introduced cli-dump.c didn't include this header:
http://sourceware.org/ml/gdb-patches/2002-03/msg00518.html
But for some reason that I couldn't find from reading the archives around
that patch's discussion, cli-dump.h was introduced in the final checkin,
at:
http://sourceware.org/ml/gdb-patches/2002-03/msg00596.html
There seems to be no point in keeping this around nowadays.

This fixes some derivation.exp regressions with "dwz -m".
The bug here is that the imported PU is given language_minimal.
However, it ought to be C++.
The "pretend language" machinery exists to solve this problem, but it
wasn't handled in process_psymtab_comp_unit. So, this patch adds it
there.
Built and regtested, both normally and using "dwz -m", on x86-64
Fedora 18.

With "dwz -m", "main" appears in both the PU and the importing CU when
running anon-struct.exp. However, the PU does not have a file name.
So, find_main_filename returns the empty string, making
deduce_language_from_filename return language_unknown.
This patch fixes this problem by changing gdb to use the ordinary
symbol-lookup functions to find "main"'s symbol. Then, it examines the
symbol's language.
I think this is cleaner than the current approach. For one thing it
avoids trying to guess the language based on the source file name,
instead deferring to the presumably more reliable debuginfo.
Another possible fix would have been to change how the file name is
found via the "qf" methods. However, I think the approach given is
preferable for the reason outlined above.
This required a minor test suite change, as now a symtab is expanded
during the search for "main".
Built and regtested (both ways) on x86-64 Fedora 18.
* symfile.c (set_initial_language): Look up "main" symbol
and use its language.

Doug pointed out a while ago that in the final dwz -m patch, nothing
ever set symtab::user.
This patch fixes this oversight and adds a test case showing why it is
important.
Built and regtested (both ways) on x86-64 Fedora 18.
The new test unconditionally tests the partial unit machinery, which I
think is an added plus.
* dwarf2read.c (recursively_compute_inclusions): Add
"immediate_parent" argument. Set symtab's "user" field

The bug here is that, with dwz -m, a function (and a label) appear in
both a PU and a CU when running cplabel.exp. So, a breakpoint gets
two locations:
(gdb) break foo::bar:to_the_top
Breakpoint 2 at 0x400503: foo::bar:to_the_top. (2 locations)
What is especially wacky is that both locations are at the same place:
(gdb) info b
Num Type Disp Enb Address What
1 breakpoint keep y <MULTIPLE>
1.1 y 0x000000000040051c foo::bar:get_out_of_here
1.2 y 0x000000000040051c foo::bar:get_out_of_here
This happens due to the weird way we run "dwz -m".
It's unclear to me that this would ever happen for real code.
While I think this borders on "diminishing returns" territory, the fix
is pretty straightforward: use the existing address-filtering function
in linespec to also filter when looking at labels.
Built and regtested (both ways) on x86-64 Fedora 18.
* linespec.c (convert_linespec_to_sals): Use maybe_add_address
when adding label symbols.

This is another patch in my ongoing series to "split" objfile to share
more read-only data across inferiors. See
http://sourceware.org/gdb/wiki/ObjfileSplitting
When symbols are finally shared, there will be no back-link from the
symbol to its containing objfile, because there may be more than one
such objfile. So, all such back-links must be removed.
One hidden back-link is the msymbol_objfile function. Since
(eventually) a symbol may appear in more than one objfile, trying to
look up the objfile given just a symbol cannot work.
This patch removes msymbol_objfile in favor of using a bound minimal
symbol. It introduces a new function to make this conversion simpler
in some spots.
The bonus of this patch is that using msymbol_objfile is slower than
simply looking up the owning objfile in the first place.

This patch fixes PR symtab/15719.
The bug is that "watch -location" crashes on a certain expression.
The problem is that fetch_subexp_value is catching an exception.

it is better for the exception to propagate.
