When handling DWARF attributes of the form DW_FORM_strp the strings
should be placed in the .debug_str section, not .debug_string as they
currently are by the DWARF assembler (in lib/dwarf.exp).
I've added a test. This is as much to test the DWARF generator as it
is to test GDB as GCC makes frequent use of DW_FORM_strp so we can be
pretty sure this part of GDB is already well tested.
gdb/testsuite/ChangeLog:
* gdb.dwarf2/dw2-using-debug-str.c: New file.
* gdb.dwarf2/dw2-using-debug-str.exp: New file.
* lib/dwarf.exp (Dwarf::DW_FORM_strp): Create .debug_str section,
not .debug_string.

The 'all_dlls' list is global. This would cause the complete dll list
to be reported for individual processes. Move the list into the
process_info struct.
Currently the dll list is used only by the win32-low target, which
does not support the multi-process feature. Therefore, it practically
does not matter whether the list is global or per-process. However,
there may be targets that are outside the binutils-gdb repo (e.g. we,
at Intel, have such a target) that have multi-process and use the dll
list. So, it makes sense to do the right thing.

This patch finally changes gdb so that an objfile can have multiple
sources of partial symbols (or mixed partial symbols and other kinds
of indices).
This is done by having each symbol reader create its own
psymbol_functions object and add it to the 'qf' list in the objfile.

This changes objfile::qf to be a forward_list, and then updates all
the uses to iterate over the list. Note that there is still only ever
a single element in the list; this is handled by clearing the list
whenever an object is added.

This removes the last references to the partial_symtab via the objfile

psymbol_functions, and maintenance_print_psymbols is changed to use
dynamic_cast to verify that it is examining partial symbols.

This adds a new method, objfile::require_partial_symbols. This reuses

Partial symbols are read via the sym_fns::sym_read_psymbols function
pointer. In order to separate the partial symbols from the objfile,
this must instead be done via a virtual method on

This changes objfile so that it doesn't construct a psymtab_storage

Currently, the storage for partial symtabs is attached to the objfile.
Ultimately, though, this direct assocation will be removed, and the
storage will be owned by the psymbol_functions object.
This patch is a step toward this goal. The storage is already managed
as a shared_ptr, to enable cross-objfile sharing, so this adds a
reference from the psymbol_functions, and changes some code in
psymtab.c to use this reference instead.

This changes the DWARF reader to reference the psymtabs via the

This moves all the psymtab statistics printing code form symmisc.c to
psymtab.c. This changes the formatting of the output a little, but
considering that it is a maint command (and, I assume, a rarely used
one), this seems fine to me.
This change helps further dissociate the psymtab from the objfile. In
the end there will be no direct connect -- only via the
quick_symbol_functions interface.

Currently the DWARF index readers reuse the objfile's partial symbol
table in order to store an addrmap. We're going to be remove the
partial symbol object, so this patch changes the DWARF reader to store
this addrmap in the per_bfd object. This object is chosen, rather
than the quick_symbol_functions subclass, because the addrmap can be
shared across objfiles.

dwarf2_build_psymtabs sets per_bfd->partial_symtabs at its end, in
order to facilitate sharing.
However, in order to diassociate partial symtabs from the objfile, we
want to change the DWARF reader to reference partial symtabs via the
per_bfd. So, we want to set this reference before reading psymtabs.
This is safe to do because the assignment is done unconditionally.

Currently, all psymbol readers access the psymtab storage via the
objfile. This is done directly at any spot requiring the storage.
In order to move psymbols out of the objfile, the psymtab_storage must
be passed in explicitly. This patch consolidates the access of the
storage in a single place in these readers, updating various functions
to pass the storage object around. "Hidden" uses, like
"objfile->psymtabs ()", are also updated.
The DWARF reader is not yet touched. That requires more complicated
changes.

objfile::psymbol_map is used to implement a Rust feature. It is
currently specific to partial symbols -- it isn't used by the DWARF
indices.
This patch moves it out of objfile and into psymbol_functions, adding
a new method to quick_symbol_functions to handle the clearing case.
This is needed because the map holds unrelocated addresses.

This changes quick_symbol_functions to be a base class with pure
virtual methods, rather than a struct holding function pointers.
Then, objfile is changed to hold a unique_ptr to an instance of this
class.
struct psymbol_functions is put into psympriv.h, and not psymtab.c,
because that is convenient later in the series.

Currently the "partial" symbol reader is attached to the objfile's
symbol functions. However, in order to allow multiple separate
partial symbol readers, this association must be changed. This patch

We're currently seeing testing of native-extended-gdbserver hang while
testing the x86_64 architecture on both Fedora 34 and Fedora Rawhide.
The test responsible for the hang is gdb.threads/fork-plus-threads.exp.
While there is clearly a problem/bug with this test on F34 and
Rawhide, it's also the case that testing should not hang. This commit
prevents the hang by waiting with the "-nowait" flag in
close_gdbserver.
The -nowait flag is also used in the kill_wait_spawned_process proc in
gdb/testsuite/lib/gdb.exp, so there is precedent for doing this.
There are also 15 other uses of "wait -i" scattered throughout the
test suite. While it's tempting to change these to also use the
-nowait flag, I think it might be safer to defer doing so until we
actually see a problem.
I've tested this patch on Fedora 32, 33, 34, and Rawhide. Results are
comparable on Fedora 32 and 33. On Fedora 34 and Rawhide, with this
commit in place, testing completes when the target_board is
native-extended-gdbserver. On those OSes, when not using this commit,
testing usually hangs due to a problem with
gdb.threads/fork-plus-threads.exp. I've also tested on all of the
mentioned OSes with target_board=native-gdbserver; for that testing,
I achieved comparable results over a number of runs. (Unfortunately
results are rarely identical due to racy tests.)

* lib/gdbserver-support.exp (gdbserver_exit): Use the
"-nowait" flag when waiting for gdbserver to exit.

ld/elf: Ignore section symbols when matching linkonce with comdat
ignored section symbols when comparing symbols in 2 sections. Since all
references to debugging sections are done with section symbols, symbols
in debugging sections are ignored and we fail to match symbols in comdat
debugging sections. Also .gnu.debuglto_.debug_* sections aren't treated
as debugging sections.
1. Treate .gnu.debuglto_.debug_ section as debugging section unless it
is marked with SHF_EXCLUDE.
2. Revert commit 994b2513281 in elf_create_symbuf.
3. Ignore section symbols only when matching non-debugging sections or
linkonce section with comdat section.
