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 removes the ALL_PSPACES macro. In this case it seemed cleanest
to change how program spaces are stored -- instead of using a linked
list, they are now stored in a std::vector.

I noticed that cp_canonicalize_string and friends copy a
unique_xmalloc_ptr to a std::string. However, this copy isn't
genuinely needed anywhere, and it serves to slow down DWARF psymbol
reading.
This patch removes the copy and updates the callers to adapt.
This speeds up the reader from 1.906 seconds (mean of 10 runs, of gdb
on a copy of itself) to 1.888 seconds (mean of 10 runs, on the same
copy as the first trial).

With target board debug-types, we have:
...
FAIL: gdb.cp/cpexprs.exp: list policy1::function
...
This is a regression triggered by commit 770479f223e "gdb: Fix toplevel types
with -fdebug-types-section".
However, the FAIL is caused by commit 4dedf84da98 "Change
decode_compound_collector to use std::vector" which changes a VEC_iterate loop
into a range loop:
...
- for (ix = 0; VEC_iterate (symbolp, sym_classes, ix, sym); ++ix)
+ unsigned int ix = 0;
+ for (const auto &sym : *sym_classes)
...
but fails to ensure that the increment of ix happens every iteration.
Fix this by calculating the index variable at the start of the loop body:
...
for (const auto &elt : *sym_classes)
{
unsigned int ix = &elt - &*sym_classes->begin ();
...
Tested on x86_64-linux, with native and target board debug-types.

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.

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 changes command_line_input to return a "const char *", which is
appropriate because the memory is owned by command_line_input. Then
it fixes up the users.
I looked at making command_line_input transfer ownership to its caller
instead, but this is complicated due to the way read_next_line is
called, so I decided against it.
Tested by rebuilding.

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.

It was observed that in some cases, placing a breakpoint in an
assembler file using filename:line-number syntax would result in the
breakpoint being placed at a different line within the file.
For example, consider this x86-64 assembler:
test:
push %rbp /* Break here. */
mov %rsp, %rbp
nop /* Stops here. */
The user places the breakpoint using file:line notation targeting the
line marked 'Break here', GDB actually stops at the line marked 'Stops
here'.
The reason is that the label 'test' is identified as the likely start
of a function, and the call to symtab.c:skip_prologue_sal causes GDB
to skip forward over the instructions that GDB believes to be part of
the prologue.
I believe however, that when debugging assembler code, where the user
has instruction-by-instruction visibility, if they ask for a specific
line, GDB should (as far as possible) stop on that line, and not
perform any prologue skipping. I don't believe that the behaviour of
higher level languages should change, in these cases skipping the
prologue seems like the correct thing to do.
In order to implement this change I needed to extend our current
tracking of when the user has requested an explicit line number. We
already tracked this in some cases, but not in others (see the changes
in linespec.c). However, once I did this I started to see some
additional failures (in tests gdb.base/break-include.exp
gdb.base/ending-run.exp gdb.mi/mi-break.exp gdb.mi/mi-reverse.exp
gdb.mi/mi-simplerun.exp) where we currently expected a breakpoint
placed at one file and line number to be updated to reference a
different line number, this was fixed by removing some code in
symtab.c:skip_prologue_sal. My concern here is that removing this
check didn't cause anything else to fail.
I have a new test that covers my original case, this is written for
x86-64 as most folk have access to such a target, however, any
architecture that has a prologue scanner can be impacted by this
change.
gdb/ChangeLog:
* linespec.c (decode_digits_list_mode): Set explicit_line to a
bool value.
(decode_digits_ordinary): Set explicit_line field in sal.
* symtab.c (skip_prologue_sal): Don't skip prologue for a
symtab_and_line that was set on an explicit line number in
assembler code. Do always update the recorded symtab and line if
we do skip the prologue.
gdb/testsuite/ChangeLog:
* gdb.arch/amd64-break-on-asm-line.S: New file.
* gdb.arch/amd64-break-on-asm-line.exp: New file.

I noticed some unnecessary casts of NULL. This removes all the
unnecessary ones, leaving only ones where we must ensure that NULL has
pointer type for passing through varargs.
I removed a couple of useless casts of 0 that I noticed while writing

The problem happens in linespec_lexer_lex_string when lexing
"b test_abi_tag_function[abi:\0" (using a notation where we make the implicit
terminating \0 explicit).
We arrrive here with (PARSER_STREAM (parser)) == ":\0":
...
/* Do not tokenize ABI tags such as "[abi:cxx11]". */
else if (PARSER_STREAM (parser) - start > 4
&& startswith (PARSER_STREAM (parser) - 4, "[abi"))
++(PARSER_STREAM (parser));
...
and consume ':', after which we end up here and consume '\0':
...
/* Advance the stream. */
++(PARSER_STREAM (parser));
...
after which (PARSER_STREAM (parser)) points past the end of the string.
Fix this by removing the first "++(PARSER_STREAM (parser))", and add an assert
to the second one to detect moving past the end-of-string.
Build and tested on x86_64-linux.

Adds an utility function to make it shorter to write the common case
of wrapping an xstrdup with a unique_xmalloc_ptr, and uses it
throughout.
Note: I tried to put this in common/common-utils.h near skip_spaces,
etc. but that is included in common/common-defs.h before
common/gdb_unique_ptr.h is included, so it would fail to compile
because gdb::unique_xmalloc_ptr isn't defined at that point yet. I
tried moving the gdb_unique_ptr.h inclusion before common-utils.h, but
that doesn't work because gdb_unique_ptr.h depends on common-utils.h
for xfree.

This replaces throw_exception with "throw;" when possible. This was
written by script. The rule that is followed is that uses of the
form:
catch (... &name)
{
...
throw_exception (name);
}
... can be rewritten. This should always be safe, because exceptions
are caught by const reference, and therefore can't be modified in the
body of the catch.

This renames the gdb exception types. The old types were only needed
due to the macros in common-exception.h that are now gone.
The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem
needed, so this patch removes it entirely.

This patch attempts to fix a bug dealing with setting breakpoints
in default symtabs that are symlinks. For example:
(gdb) list
11 GNU General Public License for more details.

13 You should have received a copy of the GNU General Public License
14 along with this program. If not, see <http://www.gnu.org/licenses/>. */

19 return 0; /* break here */
20 }
(gdb)
21
22 int
23 main (void)
24 {
25 return foo ();
26 }
(gdb) b 19
No line 19 in the current file.
Make breakpoint pending on future shared library load? (y or [n])
The problem here is that when create_sals_line_offset sets the default
symtab, it immediately calls symtab_to_fullname, passing that fullname
to collect_symtabs_from_filename to find all matching symtabs. This
fails because we end up looking for a symtab with the name of the
actual file on disk (which is different in this case because of the
symlink) instead of the one stored in the debug info.
Since we already have the lookup name of the default symtab, use it
instead of the fullname. [This fullname thing was originally added
in 2007 in a series dealing with *displaying* absolute file names.
Clearly, this instance has nothing to do with the display of file names.]

An upcoming sync with gcc's libiberty [1] will remove support for old
mangling schemes (GNU v2, Lucid, ARM, HP and EDG). It will remove the
cplus_demangle_opname function, so we need to get rid of its usages in
GDB (it's a GNU v2 specific function).
I think the changes are mostly relatively obvious, some hacks that were
necessary to support overloaded operators with GNU v2 mangling are not
needed anymore.
The change in stabsread.c is perhaps less obvious. I think we could get
rid of more code in that region that is specific to old mangling
schemes, but I chose to do only the minimal changes required to remove
the cplus_demangle_opname uses. There is also a detailed comment just
above that explaining how GNU v2 and v3 mangled symbols are handled, I
decided to leave it as-is, since I wasn't sure which part to remove,
change or leave there.

schemes.", specifically.

Fix leak by xfree-ing self->canonical_names in linespec_state_destructor.
The leak probably appeared with the patch 'Remove cleanup from linespec.c',
as there was a cleanup to xfree canonical_names before the patch.
Tested on Debian/amd64, native and under valgrind.

This commit applies all changes made after running the gdb/copyright.py
script.
Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.
gdb/ChangeLog:
Update copyright year range in all GDB files.

linespec_parser_new allocates a std::vector<symtab *> at line 2756, and stores
the pointer to this vector in PARSER_RESULT (parser)->file_symtabs. At 3
different places in linespec.c, another std::vector is assigned to a
linespec->file_symtabs, without first deleting the current value.
The leak is fixed by assigning the vector itself instead of the pointer.
Everything should be moved, so there is no significant data copy
involved.
Tested on debian/amd64, + a bunch of tests re-run under valgrind
(including the test that throws an error).

This fixes all the straightforward -Wshadow=local warnings in gdb. A
few standard approaches are used here:
* Renaming an inner (or outer, but more commonly inner) variable;
* Lowering a declaration to avoid a clash;
* Moving a declaration into a more inner scope to avoid a clash,
including the special case of moving a declaration into a loop header.
I did not consider any of the changes in this patch to be particularly
noteworthy, though of course they should all still be examined.

This change/patch substitues BLOCK_ENTRY_PC for BLOCK_START in
places where BLOCK_START is used to obtain the address at which
execution should enter the block. Since blocks can now contain
non-contiguous ranges, the BLOCK_START - which is still be the
very lowest address in the block - might not be the same as
BLOCK_ENTRY_PC.
There is a change to infrun.c which is less obvious and less mechanical.
