A plan I had a while ago was to write the DWARF index in a worker
thread. This is why objfile::partial_symtabs is a shared_ptr.
However, it turned out that doing this required keeping the objfile
alive as well. Now that objfiles are managed using shared_ptr,
there's no need for partial_symtabs to be one as well, so this patch
reverts that change.

* objfiles.h (struct objfile) <partial_symtabs>: Now a
unique_ptr.

This changes objfiles to be managed using a shared_ptr. shared_ptr is
chosen because it enables the use of objfiles in background threads.
The simplest way to do this was to introduce a new iterator that will
return the underlying objfile, rather than a shared_ptr. (I also
tried changing the rest of gdb to use shared_ptr, but this was quite
large; and to using intrusive reference counting, but this also was
tricky.)

The idea behind this is that, in the long run, some code will need to
be able to hold onto an objfile after it is unlinked from the program
space. In particular, this is needed for some functionality to be
moved to worker threads -- otherwise the objfile can be deleted while
still in use.
So, this makes ~objfile private, replacing it with an "unlink" method,
making it more obvious which operation is intended at the calling
points.

This changes the objfile constructor to be private, changing the
callers to use a factory method. This isn't perhaps strictly needed
for the goal of this series -- changing the container model of
objfiles -- but is a nice symmetry.

This avoids a conflict with a system "struct bcache" on
Solaris (see e.g.
https://www.isi.edu/nsnam/archive/ns-users/webarch/2001/msg05393.html)
Note that the Solaris conflict for now only surfaces with
--enable-targets=all (which the build bot doesn't use).

I noticed an obsolete comment just before unlink_objfile, and then I
noticed that both unlink_objfile and put_objfile_before could be
static. This patch makes these changes, and also moves unlink_objfile
earlier, so that a forward declaration is not needed.
Tested by rebuilding.

This large patch removes the unnecessary bfd parameter from various
bfd section macros and functions. The bfd is hardly ever used and if
needed for the bfd_set_section_* or bfd_rename_section functions can
be found via section->owner except for the com, und, abs, and ind
std_section special sections. Those sections shouldn't be modified
anyway.
The patch also removes various bfd_get_section_<field> macros,
replacing their use with bfd_section_<field>, and adds
bfd_set_section_lma. I've also fixed a minor bug in gas where
compressed section renaming was done directly rather than calling
bfd_rename_section. This would have broken bfd_get_section_by_name
and similar functions, but that hardly mattered at such a late stage
in gas processing.

* objfiles.h (objfile): Add a comment describing partial symbols.
|
|
I touched symtab.h and was surprised to see how many files were
rebuilt. I looked into it a bit, and found that defs.h includes
gdbarch.h, which in turn includes many things.
gdbarch.h is only needed by a minority ofthe files in gdb, so this
patch removes the include from defs.h and updates the fallout.
I did "wc -l" on the files in build/gdb/.deps; this patch reduces the
line count from 139935 to 137030; so there are definitely future
build-time savings here.
Note that while I configured with --enable-targets=all, it's possible
that some *-nat.c file needs an update. I could not test all of
these. The buildbot caught a few problems along these lines.

This is the next patch in the ongoing series to move gdbsever to the
top level.
This patch just renames the "common" directory. The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top. This approach makes the patches a bit
more tractable.
I chose the name "gdbsupport" for the directory. However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.
Tested by the buildbot.

separate debug objfiles.

objfiles.h needs "struct bcache" to be complete, so it should include

Currently, minimal symbols are allocated on the per-BFD obstack.
However, it is also possible for multiple symbol readers to create
minimal symbols for a given objfile. In this case, the minimal
symbols will be reallocated on the obstack, leading to some waste of
storage.
This is a memory leak, but I think it won't be caught by tools like
valgrind, because valgrind doesn't know about obstacks.
This patch fixes the problem by using malloc to allocate the storage
for minimal symbols.

This changes objfile_per_bfd_storage::demangled_names_hash to be an

There's no reason that the objfile_per_bfd_storage must be allocated
via bfd_alloc. This patch changes objfile_per_bfd_storage to be
managed more simply, via ordinary new and delete; and moves some code
into its (new) destructor.
While doing this I also noticed an extra initialization of
language_of_main, and removed it.

I noticed that objfile_per_bfd_storage::demangled_hash_languages is a
std::vector, which seemed quite large for something that,
fundamentally, can be represented as a bitset. This patch

This somewhat C++-ifies bcache. It replaces bcache_xmalloc and

This simplifies the minimal symbol iterator, by using
minimal_symbol_count and just doing a somewhat ordinary array-like

references.

Previously, the psymtab obstack was just a pointer to the objfile
obstack. This patch changes psymtabs to use their own obstack,
instead. A gdb::optional is used to avoid unnecessary allocation when
the obstack is not needed.
After this patch, the psymtab code lifetime model is that, in the core
psymtab code, objects allocated on the psymtab obstack may point to
other such objects, or to objects on the per-BFD obstack -- but never
to the objfile obstack.
Note however that this invariant is only obeyed the core psymtab code,
and even there not quite fully: there is still a link from the psymtab
to the full symtab.
Symbol readers are free to work however they like; and in particular,
even after this patch, in practice all symbol readers violate this
invariant via the read_symtab_private field.

This introduces a new method, objfile::reset_psymtabs, and changes
reread_symbols to use it. This method simply destroys the existing
partial symbols and recreates the psymtab_storage object.
This patch fixes a latent bug -- namely, that reread_symbols should
clear objfile::psymbol_map, but does not. I can submit that
separately if you'd prefer.

* symfile.c (reread_symbols): Call objfile->reset_psymtabs.
* objfiles.h (objfile::reset_psymtabs): New method.
|
|
This introduces a new psymtab_storage class, which holds all
psymbol-related objects that are independent of the objfile. (This
latter contraint explains why psymbol_map was not moved; though this
could still be done with some work.)
This patch does not yet change where psymtab allocation is done --
that comes later. This just wraps everything in a single object to
make further transformations simpler.
Note that a shared_ptr is used to link from the objfile to the
psymtab_storage object. The end goal here is to allow a given symbol
reader to simply attach to the psymtab_storage object to the BFD, then
reuse it in later invocations; shared_ptr makes this simple to reason
about.

gdb/ChangeLog:
Update copyright year range in all GDB files
|
|
In Rust, virtual tables work a bit differently than they do in C++. In
C++, as you know, they are connected to a particular class hierarchy.
Rust, instead, can generate a virtual table for potentially any type --
in fact, one such virtual table for each trait (a trait is similar to an
abstract class or to a Java interface) that a type implements.
Objects that are referenced via a trait can't currently be inspected by
gdb. This patch implements the Rust equivalent of "set print object".
gdb relies heavily on the C++ ABI to decode virtual tables; primarily to
make "set print object" work; but also "info vtbl". However, Rust does
not currently have a specified ABI, so this approach seems unwise to
emulate.
Instead, I've changed the Rust compiler to emit some DWARF that
describes trait objects (previously their internal structure was
opaque), vtables (currently just a size -- but I hope to expand this in
the future), and the concrete type for which a vtable was emitted.
The concrete type is expressed as a DW_AT_containing_type on the
vtable's type. This is a small extension to DWARF.
This patch adds a new entry to quick_symbol_functions to return the
symtab that holds a data address. Previously there was no way in gdb to
look up a full (only minimal) non-text symbol by address. The psymbol
implementation of this method works by lazily filling in a map that is
added to the objfile. This avoids slowing down psymbol reading for a
feature that is likely to not be used too frequently.
I did not update .gdb_index. My thinking here is that the DWARF 5
indices will obsolete .gdb_index soon-ish, meaning that adding a new
feature to them is probably wasted work. If necessary I can update the
DWARF 5 index code when it lands in gdb.
Regression tested on x86-64 Fedora 25.

Summary:
- This is preparation for supporting wild name matching on C++ too.
- This is also preparation for TAB-completion fixes.
- Makes symbol name matching (think strcmp_iw) be based on a per-language method.
- Merges completion and non-completion name comparison (think
language_ops::la_get_symbol_name_cmp generalized).
- Avoid re-hashing lookup name multiple times
- Centralizes preparing a name for lookup (Ada name encoding / C++ Demangling),
both completion and non-completion.
- Fixes Ada latent bug with verbatim name matches in expressions
- Makes ada-lang.c use common|symtab.c completion code a bit more.
Ada's wild matching basically means that
"(gdb) break foo"
will find all methods named "foo" in all packages. Translating to
C++, it's roughly the same as saying that "break klass::method" sets
breakpoints on all "klass::method" methods of all classes, no matter
the namespace. A following patch will teach GDB about fullname vs
wild matching for C++ too. This patch is preparatory work to get
there.
Another idea here is to do symbol name matching based on the symbol
language's algorithm. I.e., avoid dependency on current language set.
This allows for example doing
(gdb) b foo::bar< int > (<tab>
and having gdb name match the C++ symbols correctly even if the
current language is C or Assembly (or Rust, or Ada, or ...), which can
easily happen if you step into an Assembly/C runtime library frame.
By encapsulating all the information related to a lookup name in a
class, we can also cache hash computation for a given language in the
lookup name object, to avoid recomputing it over and over.
Similarly, because we don't really know upfront which languages the
lookup name will be matched against, for each language we store the
lookup name transformed into a search name. E.g., for C++, that means
demangling the name. But for Ada, it means encoding the name. This
actually forces us to centralize all the different lookup name
encoding in a central place, resulting in clearer code, IMO. See
e.g., the new ada_lookup_name_info class.
The lookup name -> symbol search name computation is also done only
once per language.
The old language->la_get_symbol_name_cmp / symbol_name_cmp_ftype are
generalized to work with both completion, and normal symbol look up.
At some point early on, I had separate completion vs non-completion
language vector entry points, but a single method ends up being better
IMO for simplifying things -- the more we merge the completion /
non-completion name lookup code paths, the less changes for bugs
causing completion vs normal lookup finding different symbols.
The ada-lex.l change is necessary because when doing
(gdb) p <UpperCase>
then the name that is passed to write_ write_var_or_type ->
ada_lookup_symbol_list misses the "<>", i.e., it's just "UpperCase",
and we end up doing a wild match against "UpperCase" lowercased by
ada_lookup_name_info's constructor. I.e., "uppercase" wouldn't ever
match "UpperCase", and the symbol lookup fails.
This wouldn't cause any regression in the testsuite, but I added a new
test that would pass before the patch and fail after, if it weren't
for that fix.
This is latent bug that happens to go unnoticed because that
particular path was inconsistent with the rest of Ada symbol lookup by
not lowercasing the lookup name.
Ada's symbol_completion_add is deleted, replaced by using common
code's completion_list_add_name. To make the latter work for Ada, we
needed to add a new output parameter, because Ada wants to return back
a custom completion candidates that are not the symbol name.
With this patch, minimal symbol demangled name hashing is made
consistent with regular symbol hashing. I.e., it now goes via the
language vector's search_name_hash method too, as I had suggested in a
previous patch.
dw2_expand_symtabs_matching / .gdb_index symbol names were a
challenge. The problem is that we have no way to telling what is the
language of each symbol name found in the index, until we expand the
corresponding full symbol, which is off course what we're trying to
avoid. Language information is simply not considered in the index
format... Since the symbol name hashing and comparison routines are
per-language, we now have a problem. The patch sorts this out by
matching each name against all languages. This is inneficient, and
indeed slows down completion several times. E.g., with:
$ cat script.cmd
set pagination off
set $count = 0
while $count < 400
complete b string_prin
printf "count = %d\n", $count
set $count = $count + 1
end
$ time gdb --batch -q ./gdb-with-index -ex "source script-string_printf.cmd"
I get, before patch (-O2, x86-64):
real 0m1.773s
user 0m1.737s
sys 0m0.040s
While after patch (-O2, x86-64):
real 0m9.843s
user 0m9.482s
sys 0m0.034s
However, the following patch will optimize this, and will actually
make this use case faster compared to the "before patch" above:
real 0m1.321s
user 0m1.285s
sys 0m0.039s
