Delete two more symbol/section related macros. This time it's
SYMBOL_SECTION and MSYMBOL_SECTION.
As with general_symbol_info::m_name it is not currently possible to
make general_symbol_info::m_section private as general_symbol_info
must remain a POD type.
But other than failing to make the new m_section private, this change
does what you'd expect, adds a get and set member function and updates
all users to use the new functions instead of the previous wrapper
macros.
There should be no user visible change after this commit.

Many spots incorrectly use only spaces for indentation (for example,
there are a lot of spots in ada-lang.c). I've always found it awkward
when I needed to edit one of these spots: do I keep the original wrong
indentation, or do I fix it? What if the lines around it are also
wrong, do I fix them too? I probably don't want to fix them in the same
patch, to avoid adding noise to my patch.
So I propose to fix as much as possible once and for all (hopefully).
One typical counter argument for this is that it makes code archeology
more difficult, because git-blame will show this commit as the last
change for these lines. My counter counter argument is: when
git-blaming, you often need to do "blame the file at the parent commit"
anyway, to go past some other refactor that touched the line you are
interested in, but is not the change you are looking for. So you
already need a somewhat efficient way to do this.
Using some interactive tool, rather than plain git-blame, makes this
trivial. For example, I use "tig blame <file>", where going back past
the commit that changed the currently selected line is one keystroke.
It looks like Magit in Emacs does it too (though I've never used it).
Web viewers of Github and Gitlab do it too. My point is that it won't
really make archeology more difficult.
The other typical counter argument is that it will cause conflicts with
existing patches. That's true... but it's a one time cost, and those
are not conflicts that are difficult to resolve. I have also tried "git
rebase --ignore-whitespace", it seems to work well. Although that will
re-introduce the faulty indentation, so one needs to take care of fixing
the indentation in the patch after that (which is easy).

The "n_psyms" statistic in the per-objfile stats is not really needed,
but its use requires passing the objfile to add_psymbol. This patch
removes the field in favor of counting the psyms when needed.
Note that this is not exactly equivalent -- in the old approach, a
psymbol can in theory be created and then the psymtab discarded, which
would increment the counter. This does not seem very important to me.
I rewrote the code to count partial symbols; though TBH I think that
this information is not really very useful.

Currently pointers to all partial symbols are stored in two vectors;
and then indices into these vectors are stored in each partial_symtab.
This patch changes this so that each partial symtab instead has
vectors of symbols. add_psymbol_to_list can now be changed into a
method on partial_symtab as well.
My main motivation for doing this is that I am looking into calling
sort_pst_symbols in the background. However, I haven't actually
implemented this yet. (Also this may make it more feasible to also
sort the static psymbols, though I haven't tried that either.)
Also, though, this lets us remove the "current_global_psymbols"
vector, because now the callers can simply refer directly to the
psymtab that they are modifying (formerly this was implicit).
The main drawback of this patch is that it increases the size of
partial symtab.

This commit changes the language_data::la_get_symbol_name_matcher
function pointer member variable into a member function of
language_defn.
There should be no user visible changes after this commit.
Before this commit access to the la_get_symbol_name_matcher function
pointer was through the get_symbol_name_matcher function, which looked
something like this (is pseudo-code):
<return-type>
get_symbol_name_matcher (language_defn *lang, <other args>)
{
if (current_language == ada)
current_language->la_get_symbol_name_matcher (<other args>);
else
lang->la_get_symbol_name_matcher (<other args>);
}
In this commit I moved the get_symbol_name_matcher as a non-virtual
function in the language_defn base class, I then add a new virtual
method that is only used from within get_symbol_name_matcher, this can
then be overridden by specific languages as needed. So we now have:
class language_defn
{
<return-type> get_symbol_name_matcher (<args>)
{
if (current_language == ada)
return current_language->get_symbol_name_matcher_inner (<args>);
else
return this->get_symbol_name_matcher_inner (<args>);
}
virtual <return-type> get_symbol_name_matcher_inner (<args>)
{
....
}
}

This series will cause partial symtabs to be shared across objfiles.
However, full symtabs and symbols will still be objfile-dependent, so
will be expanded separately for each objfile. So, a debug info reader
will need to know which objfile to consult when expanding a partial
symtab.
This patch adds an objfile parameter to the two relevant methods of
partial_symtab. Current implementations simply ignore them.

This adds a new overload of add_psymbol_to_list. This one takes an
already constructed psymbol and adds it to the bcache and the
appropriate list.
This seemed cleaner than continuing to add parameters to the existing

constructed.

When running test-case gdb.ada/dgopt.exp with target board
unix/-flto/-O0/-flto-partition=none/-ffat-lto-objects and gcc-8, gcc-9 or
gcc-10, and the fix for PR25700, we run into this regression:
...
(gdb) list x.adb:16, 16^M
No source file named x.adb.^M
(gdb) FAIL: gdb.ada/dgopt.exp: list x.adb:16, 16
...
The reason for the failure is that without the fix for PR25700, we
have an unshared psymtab:
...
{ psymtab gdb.ada/dgopt/x.adb ((struct partial_symtab *) $hex)^M
readin no^M
fullname (null)^M
text addresses 0x0 -- 0x0^M
psymtabs_addrmap_supported yes^M
globals (none)^M
statics (none)^M
dependencies (none)^M
}^M
...
and a shared psymtab (with user field set):
...
{ psymtab gdb.ada/dgopt/x.adb ((struct partial_symtab *) $hex)^M
readin no^M
fullname (null)^M
text addresses 0x0 -- 0x0^M
psymtabs_addrmap_supported yes^M
globals (none)^M
statics (none)^M
user <artificial>@0x159a ((struct partial_symtab *) 0x37b57c0)^M
dependencies (none)^M
}^M
...
The fix for PR25700 removes the unshared psymtab.
Then when trying to find a psymtab matching x.adb in
psym_map_symtabs_matching_filename, we run into this continue for the shared
psymtab:
...
for (partial_symtab *pst : require_partial_symbols (objfile, true))
{
/* We can skip shared psymtabs here, because any file name will be
attached to the unshared psymtab. */
if (pst->user != NULL)
continue;
...
and consequently cannot find the file.
Fix this by not skipping the shared symtab in
psym_map_symtabs_matching_filename.
Build and reg-tested on x86_64-linux.

This changes get_objfile_arch to be a new inline method,
objfile::arch.
To my surprise, this function came up while profiling DWARF psymbol
reading. Making this change improved performance from 1.986 seconds
to 1.869 seconds. Both measurements were done by taking the mean of
10 runs on a fixed copy of the gdb executable.

Consider this test-case, consisting of header file hello.h:
...
inline static const char*
foo (void)
{
return "foo";
}
...
and source file hello.c:
...
int
main (void)
{
printf ("hello: %s\n", foo ());
return 0;
}
...
compiled with -g:
...
$ gcc hello.c -g
...
When trying to expand the partial symtab for hello.h:
...
$ gdb -batch \
-iex "set language c" \
a.out \
-ex "maint expand-symtabs hello.h" \
-ex "maint info psymtabs"
...
we in fact find that the partial symtab for hello.h (and corresponding
includer partial symtab hello.c) have not been expanded:
...
{ psymtab hello.h ((struct partial_symtab *) 0x27cf070)
readin no
...
{ psymtab hello.c ((struct partial_symtab *) 0x2cf09e0)
readin no
...
This is due to the recursively_search_psymtabs call in
psym_expand_symtabs_matching:
...
if (recursively_search_psymtabs (ps, objfile, domain,
lookup_name, symbol_matcher))
...
which always returns false for symbolless partial symtabs.
The same problem occurs with CUs where the dwarf is generated by gas
--gdwarf-2 for a foo.S: if we read such a test-case with -readnow, we'll have
a symbolless symtab for foo.S. But if we read the test-case with partial
symtabs, and expand those using "maint expand-symtabs", the foo.S psymtab
remains unexpanded.
Fix this by passing a NULL symbol_matcher and lookup_name to
expand_symtabs_matching in maintenance_expand_symtabs, and skipping the call
to recursively_search_psymtabs if symbol_matcher == NULL and
lookup_name == NULL.
Build and tested on x86_64-linux, with native.
In addition, tested test-case with target boards cc-with-gdb-index.exp,
cc-with-debug-names.exp and readnow.exp.

Consider test-case inline.c, containing an inline function foo:
...
static inline int foo (void) { return 0; }
int main (void) { return foo (); }
...
And the test-case compiled with -O2 and debug info:
...
$ gcc -g inline.c -O2
...
This results in a DWARF entry for foo without pc info:
...
<1><114>: Abbrev Number: 4 (DW_TAG_subprogram)
<115> DW_AT_name : foo
<119> DW_AT_decl_file : 1
<11a> DW_AT_decl_line : 2
<11b> DW_AT_prototyped : 1
<11b> DW_AT_type : <0x10d>
<11f> DW_AT_inline : 3 (declared as inline and inlined)
...
When loading the executable in gdb, we create a partial symbol for foo, but
after expansion into a full symbol table no actual symbol is created,
resulting in a maint check-psymtab failure:
...
(gdb) maint check-psymtab
Static symbol `foo' only found in inline.c psymtab
...
Fix this by skipping this type of partial symbol during the check.
Note that we're not fixing this by not creating the partial symbol, because
this breaks setting a breakpoint on an inlined inline function in a CU for
which the partial symtab has not been expanded (test-case
gdb.dwarf2/break-inline-psymtab.exp).

When language is set to auto, part of loading an executable is to update the
language accordingly. This is implemented by set_initial_language.
The implementation of set_initial_language works as follows:
- check if any objfile in the progspace has name_of_main/language_of_main
set, and if so, use the first one found. [ This is what you get f.i. when
using dwarf with DW_AT_main_subprogram. ]
- otherwise, check for known names in the minimal symbols, and either:
- use the associated language if any (f.i. for ada), or
- lookup the symbol in the symtab for the name and use the symbol language
(f.i. for c/c++).
The symbol lookup can be slow though.
In the case of the cc1 binary from PR23710 comment 1, getting to the initial
prompt takes ~8s:
...
$ time.sh gdb cc1 -batch -ex "show language"
The current source language is "auto; currently c++".
maxmem: 1272260
real: 8.05
user: 7.73
system: 0.38
...
but if we skip guessing the initial language by setting it instead, it takes
only ~4s:
...
$ time.sh gdb -iex "set language c++" cc1 -batch -ex "show language"
The current source language is "c++".
maxmem: 498272
real: 3.99
user: 3.90
system: 0.15
...
In both cases, we load the partial symbols for the executable, but in the
first case only we also do a lookup of main, which causes the corresponding
partial symtab to be expanded into a full symtab.
Ideally, we'd like to get the language of the symbol without triggering
expansion into a full symtab, and get the speedup without having to set the
language manually.
There's a related fixme in the header comment of set_initial_language:
...
/* Set the initial language.
FIXME: A better solution would be to record the language in the
psymtab when reading partial symbols, and then use it (if known) to
set the language. This would be a win for formats that encode the
language in an easily discoverable place, such as DWARF. For
stabs, we can jump through hoops looking for specially named
symbols or try to intuit the language from the specific type of
stabs we find, but we can't do that until later when we read in
full symbols. */
void
set_initial_language (void)
...
Since we're already tracking the language of partial symbols, use this to set
the language for the main symbol.
Note that this search in partial symbol tables is not guaranteed to yield the
same result as the lookup_symbol_in_language call currently done in
set_initial_language.

lookup_name_info always copies the name that is passed in. However,
normally a copy is not needed. This patch changes this class to avoid
copying. This required changing the "name" method to return something
else; I chose a gdb::string_view, to avoid excessive calls to strlen
in the code using the lookup_name_info. However, as this class does
not allow an arbitrary string_view, I've also added a c_str method
that guarantees a \0-terminated result -- a pedantic difference but
one that respects the string_view contract, IMO.

I noticed that psymtab.c was always copying the search string in
psymtab_search_name, even when it wasn't necessary. This patch
removes this function in favor of using the make_ignore_params feature
of lookup_name_info.
Once I had done that, I noticed that lookup_partial_symbol was
creating a lookup_name_info. However, this function called in loops,
causing even more excess allocation. This patch further fixes this by
hosting the creation of the lookup_name_info into the callers.

This method calls partial_symtab::expand_psymtab on all dependencies of

The type struct partial_symtab contains two fields (disregarding field next)
that express relations with other symtabs: user and dependencies.
When using "maint print psymbols", we see both the dependencies and the user
fields:
...
Partial symtab for source file (object 0x35ef270)
...
Depends on 0 other partial symtabs.
Shared partial symtab with user 0x35d5f40
...
But with "maint info psymtabs", we only see dependencies:
...
{ psymtab ((struct partial_symtab *) 0x35ef270)
...
dependencies (none)
}
...
Add printing of the user field for "maint info psymtabs", such that we have:
...
{ psymtab ((struct partial_symtab *) 0x35ef270)
...
+ user hello.c ((struct partial_symtab *) 0x35d5f40)
dependencies (none)
}
...

Consider test-case gdb.dwarf2/imported-unit.exp.
It contains a CU with type int:
...
<0><129>: Abbrev Number: 2 (DW_TAG_compile_unit)
<12a> DW_AT_language : 4 (C++)
<12b> DW_AT_name : imported_unit.c
<1><13b>: Abbrev Number: 3 (DW_TAG_base_type)
<13c> DW_AT_byte_size : 4
<13d> DW_AT_encoding : 5 (signed)
<13e> DW_AT_name : int
...
which is imported in another CU:
...
<0><d2>: Abbrev Number: 2 (DW_TAG_compile_unit)
<d3> DW_AT_language : 4 (C++)
<d4> DW_AT_name : <artificial>
<1><e1>: Abbrev Number: 3 (DW_TAG_imported_unit)
<e2> DW_AT_import : <0x129> [Abbrev Number: 2]
...
However, if we print the partial symbols:
...
$ gdb -batch imported-unit -ex "maint print psymbols"
...
we see type int both in the importing CU:
...
Partial symtab for source file <artificial>@0xc7 (object 0x29f9b80)
...
Depends on 1 other partial symtabs.
0 0x2a24240 imported_unit.c
Global partial symbols:
`main', function, 0x4004b2
Static partial symbols:
`int', type, 0x0
...
and in the imported CU:
...
Partial symtab for source file imported_unit.c (object 0x2a24240)
...
Depends on 0 other partial symtabs.
Shared partial symtab with user 0x29f9b80
Static partial symbols:
`int', type, 0x0
...
This is an artefact resulting from the fact that all CUs in an objfile
share the same storage array for static partial symbols (and another array for
global partial symbols), using a range to describe their symbols.
Then when scanning the partial symbols of a CU and encountering an import, either:
- the referred CU has not been parsed yet, and will be parsed, and the range of
static partial symbols of the referred CU will be a subrange of the range of
static partial symbols of this CU, or
- the referred CU has already been parsed, and the range of static partial
symbols of the referred CU will not be a subrange of the range of static
partial symbols of this CU.
This is inconsistent handling, and confuses the notion of a symbol belonging to
a single symtab.
Furthermore, it might slow down searches, given that the symbol needs to be
skipped twice.
Finally, the same issue holds for global partial symbols, where the range of a
CU is sorted after parsing is finished. Obviously sorting the range of a CU
may invalidate subranges, effectively moving symbols in and out of imported
CUs.
Fix this for both static and global partial symbols, by gathering partial
symbols in a per-CU vector, and adding those symbols to the per-objfile
storage only once complete.
Tested on x86_64-linux, with native and board cc-with-dwz and cc-with-dwz-m.

This introduces a string cache on the per-BFD object, replacing the
macro and filename caches. Both of these caches just store strings,
so this consolidation by itself saves a little memory (about the size
of a bcache per objfile).
Then this patch switches some allocations on the objfile obstack to
use this bcache instead. This saves more space; and turns out to be a
bit faster as well.
Here are the before and after "maint time" + "maint space" results of
"file ./gdb":
Command execution time: 4.664021 (cpu), 4.728518 (wall)

I noticed a regression with board cc-with-dwz:
...
FAIL: gdb.cp/m-static.exp: static const int initialized elsewhere
FAIL: gdb.cp/m-static.exp: info variable everywhere
...
The problem started with commit 0494dbecdf "Consolidate partial symtab
dependency reading".
The commit replaces the dwarf2_psymtab::expand_psymtab specific reading of
dependencies, which contains a "dependencies[i]->user == NULL" test, with a
generic partial_symtab::read_dependencies call, which does not test the user
field.
This patch fixes the regression by adding back the test, in the generic
partial_symtab::read_dependencies.

Tested natively, as well as with boards cc-with-dwz and cc-with-dwz-m.

This patch removes the "readin" and "compunit_symtab" members from
partial_symtab, replacing them with methods. Then it introduces a new
"standard_psymtab" class, which restores these members; and changes
the symbol readers to use this intermediate class as the base class of
their partial symtab subclasses.
The reason for this is to make it possible for a symbol reader to
implement an alternate mapping between partial and full symbol tables.
This is important in order to be able to share psymtabs across
objfiles -- whether a psymtab has been "readin" is objfile-dependent,
as are the pointers to the full symbol tables.

This introduces a new partial_symtab::read_symtab method, and updates
the symbol readers to subclass partial_symtab and implement this
method. The old read_symtab and read_symtab_private members are
removed.
In practice, only DWARF and CTF are truly updated to take advantage of
the new setup. The other symbol readers are less actively maintained,
and so this patch also introduces a "legacy_psymtab", which
essentially works the same way as the old partial_symtab.
(Note that, without more knowledge of the interaction between these
symbol readers, fixing this to remove the new (small) overhead is not
trivial, because these readers copy the read_symtab pointer between
partial symtabs.)

psymtab_storage. However, eventually we want to subclass partial

This changes psymtabs to be allocated with new and destroyed with
delete. As a consequence, the psymtab free-list is also removed.
The motivation for this is to let symbol readers subclass
partial_symtab.

The pattern
objfile->section_offsets[SECT_OFF_TEXT (objfile)]
... appears very often, to get the offset of the text section of an
objfile. I thought it would be more readable to write it as:
objfile->text_section_offset ()
... so I added this method and used it where possible. I also added
data_section_offset, although it is not used as much.

I'd like to enable the -Wmissing-declarations warning. However, it
warns for every _initialize function, for example:
CXX dcache.o
/home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’:
/home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations]
_initialize_dcache (void)
^~~~~~~~~~~~~~~~~~
The only practical way forward I found is to add back the declarations,
which were removed by this commit:
commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9
Author: John Baldwin <jhb@FreeBSD.org>
Date: Sat Sep 9 11:02:37 2017 -0700
Remove unnecessary function prototypes.
I don't think it's a big problem to have the declarations for these
functions, but if anybody has a better solution for this, I'll be happy
to use it.

This changes section_offsets to be specialization of a std::vector and
updates all the users. It also removes the ANOFFSET and
SIZEOF_N_SECTION_OFFSETS macros.
Most of this is just a generic sort of cleanup, that reduces the
number of lines of code. However, a couple spots were doing weird
things.
objfile_relocate did:
- std::vector<struct section_offsets>
- new_debug_offsets (SIZEOF_N_SECTION_OFFSETS (debug_objfile->num_sections));
... which seems to greatly over-estimate the number of elements
needed.
This appeared in set_objfile_default_section_offset:
- std::vector<struct section_offsets> offsets (objf->num_sections,
- { { offset } });
... which makes sense due to type safety, but is also actively
confusing given that section_offsets was previously also a kind of
vector type.
Tested on x86-64 Fedora 30.

This also renames it to make it clearer that this is not a cheap
function (to compute_and_set_names). Also renames name to m_name
to make the implementation of the renamed function more readable.
Most of the places that access sym->m_name directly were also changed
to call linkage_name () instead, to make it clearer which name they
are accessing.

a new function general_symbol_info::set_language. symbol and minimal_symbol
already inherit from that struct so this works naturally.

Also renames the member variable to m_language to make code easier to read
when more functions become member functions.
I was originally hoping to eventually make m_language private (after a few
more patches), but unfortunately then it no longer counts as a POD type,
which means gdbsupport/poison.h won't let us use memset to initialize
this type, which psymtabs rely on to clear padding bytes so that bcache
can work properly.

This function is not just slower than xxhash, it is slower than
even libiberty's iterative_hash, so there does not seem to be
a reason for it to exist.

I went through most of the spots that include readline.h and, when
appropriate, either removed the include or changed it to include
tilde.h.
Note that remote-sim.c and bsd-kvm.c could probably include tilde.h
instead, but I did not change these. I think I can't build the
latter, and I didn't want to set up a sim build for the former.
Tested by rebuilding.

Add a new command 'info modules' that lists all of the modules GDB
knows about from the debug information.
A module is a debugging entity in the DWARF defined with
DW_TAG_module, currently Fortran is known to use this tag for its
modules. I'm not aware of any other language that currently makes use
of DW_TAG_module.
The output style is similar to the 'info type' output:
(gdb) info modules
All defined modules:
File info-types.f90:
16: mod1
24: mod2
(gdb)
Where the user is told the file the module is defined in and, on the
left hand side, the line number at which the module is defined along
with the name of the module.
This patch is a new implementation of an idea originally worked on by
Mark O'Connor, Chris January, David Lecomber, and Xavier Oro from ARM.

Just some code cleanup. This change has a few benefits:
- Shorter argument list in the functions
- If the caller needs to calculate the string, they no longer
need to explicitly call strlen
- It is easy to pass std::string to this (done in one place
currently)
This also updates a couple of places that were passing 0/1 to
a bool parameter.
