I noticed when running test-case gdb.ada/info_exc.exp with glibc debug info
installed, that the "info exceptions" command that lists all Ada exceptions
also expands non-Ada CUs, which includes CUs in
/lib64/ld-linux-x86-64.so.2 and /lib64/libc.so.6.
Fix this by:
- adding a new lang_matcher parameter to the expand_symtabs_matching
function, and
- using that new parameter in the expand_symtabs_matching call in
ada_add_global_exceptions.
The new parameter is a hint, meaning implementations are free to ignore it and
expand CUs with any language. This is the case for partial symtabs, I'm not
sure whether it makes sense to implement support for this there.
Conversely, when processing a CU with language C and name "<artificial>"
(as produced by GCC LTO), the CU may not really have a single language and we
should ignore the lang_matcher. See also commit d2f67711730
("Fix 'catch exception' with -flto").
Now that we have lang_matcher available, also use it to limit name splitting
styles and symbol matchers to those applicable to the matched languages.
Without this patch we have (with a gdb build with -O0):
...
$ time gdb -q -batch -x outputs/gdb.ada/info_exc/gdb.in.1 > /dev/null
real 0m1.866s
user 0m2.089s
sys 0m0.120s
...
and with this patch we have:
...
$ time gdb -q -batch -x outputs/gdb.ada/info_exc/gdb.in.1 > /dev/null
real 0m0.469s
user 0m0.777s
sys 0m0.051s
...
Or, to put it in terms of number of CUs, we have 1853 CUs:
...
$ gdb -q -batch -readnow outputs/gdb.ada/info_exc/foo \
-ex start \
-ex "maint info symtabs" \
| grep -c " name "
1853
...
Without this patch, we have:
...
$ gdb -q -batch outputs/gdb.ada/info_exc/foo \
-ex start \
-ex "info exceptions" \
-ex "maint info symtabs" \
| grep -c " name "
1393
...
so ~75% of the CUs is expanded, and with this patch we have:
...
$ gdb <same-as-above>
20
...
so ~1% of the CUs is expanded.
Tested on x86_64-linux.

This is a simple find / replace from "struct bound_minimal_symbol" to
"bound_minimal_symbol", to make things shorter and more consisten
througout. In some cases, move variable declarations where first used.

This changes quick_symbol_functions::lookup_global_symbol_language to
accept domain_search_flags rather than just a domain_enum, and fixes
up the fallout.
To avoid introducing any regressions, any code passing VAR_DOMAIN now
uses SEARCH_VFT.
That is, no visible changes should result from this patch. However,
it sets the stage to refine some searches later on.
|
|
This patch changes gdb to replace search_domain with
domain_search_flags everywhere. search_domain is removed.

This commit is the result of the following actions:
- Running gdb/copyright.py to update all of the copyright headers to
include 2024,
- Manually updating a few files the copyright.py script told me to
update, these files had copyright headers embedded within the
file,
- Regenerating gdbsupport/Makefile.in to refresh it's copyright
date,
- Using grep to find other files that still mentioned 2023. If
these files were updated last year from 2022 to 2023 then I've
updated them this year to 2024.
I'm sure I've probably missed some dates. Feel free to fix them up as
you spot them.

quick_symbol_functions::read_partial_symbols is no longer implemented,
so both it and quick_symbol_functions::can_lazily_read_symbols can be
removed. This allows for other functions to be removed as well.
Note that SYMFILE_NO_READ is now pretty much dead. I haven't removed
it here -- but could if that's desirable. I tend to think that this
functionality would be better implemented in the core; but whenever I
dive into the non-DWARF readers it is pretty depressing.

This adds a new compute_main_name method to quick_symbol_functions.
Currently there are no implementations of this, but a subsequent patch
will add one.
|
|
The only caller of quick_symbol_functions::expand_matching_symbols was
removed, so now this method and all implementations of it can be
removed.
|
|
This commit is the result of running the gdb/copyright.py script,
which automated the update of the copyright year range for all
source files managed by the GDB project to be updated to include
year 2023.

quick_symbol_functions::relocated is only needed for psymtabs, and
there it is only needed for Rust. However, because we've switched the
DWARF reader away from psymtabs, this means there's no longer a need
for this method at all.
|
|
This commit brings all the changes made by running gdb/copyright.py
as per GDB's Start of New Year Procedure.
For the avoidance of doubt, all changes in this commits were
performed by the script.

While working on my series to replace the DWARF psymbol reader, I
noticed that the expand_symtabs_matching has an undocumented
invariant. I think that, if this invariant is not followed, then GDB
will crash. So, this patch documents this in the relevant spots and
introduces some asserts to make it clear.
Regression tested on x86-64 Fedora 32.

Adds a new function to the quick_symbol_functions API to let us know
if there are any unexpanded symbols. This functionality is required
by a later commit. After this commit the functionality is unused, and
untested.
The new function objfile::has_unexpanded_symtabs is added to the
symfile-debug.c file which is a little strange, but this
is (currently) where many of the other objfile::* functions (that call
onto the quick_symbol_functions) are defined, so I'm reluctant to
break this pattern.
There should be no user visible changes after this commit.

quick_symbol_functions::map_matching_symbols is only used by the Ada
code. Currently, it both expands certain psymtabs and then walks over
the full symtabs -- including any already-expanded ones -- calling a
callback.
It appears to work lazily as well, in that if the callback returns
false, iteration stops. However, only the psymtab implementation does
this; the DWARF index implementations are not lazy. It turns out,
though, that the only callback that is ever passed here never returns
false.
This patch simplifies this method by removing the callback. The
method is also renamed. In the new scheme, the caller is responsible
for walking the full symtabs, which removes some redundancy as well.

Currently, expand_symtabs_matching only accepts a search_domain
parameter. However, lookup_symbol uses a domain_enum instead, and the
two, confusingly, do quite different things -- one cannot emulate the
other. So, this patch adds a domain_enum parameter to
expand_symtabs_matching, with UNDEF_DOMAIN used as a wildcard.
This is another step toward replacing lookup_symbol with
expand_symtabs_matching.

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.

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

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.
