For brevity, I chose the name "compunit" instead of "compunit_symtab"
the the field, getter and setter names. Since we are already in symtab

Make compunit_filetabs, used to iterate a compunit_symtab's filetabs, a
method of compunit_symtab. The name filetabs conflicts with the current
name of the field. Rename the field to m_filetabs, since at this point
nothing outside of compunit_symtab uses it, so we should treat it as
private (even though it's not actually private). Rename the
last_filetab field to m_last_filetab as well (it's only used on
compunit_symtab::add_filetab).
Adjust the COMPUNIT_FILETABS macro to keep its current behavior of
returning the first filetab.

I think it only really makes sense to call wrap_here with an argument
consisting solely of spaces. Given this, it seemed better to me that
the argument be an int, rather than a string. This patch is the
result. Much of it was written by a script.
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.
There are some loops in gdb that use ARRAY_SIZE (or a wordier
equivalent) to loop over a static array. This patch changes some of
these to use foreach instead.
Regression tested on x86-64 Fedora 34.
I noticed that global_symbol_searcher::expand_symtabs always passes a
file matcher to expand_symtabs_matching. However, if 'filenames' is
empty, then this always returns true. It's slightly more efficient to
pass a null file matcher in this case, because that lets the "quick"
symbol implementations skip any filename checks.
Regression tested on x86-64 Fedora 34.
I noticed that some methods in language_defn could use
unique_xmalloc_ptr<char> rather than a plain 'char *'. This patch
implements this change, fixing up the fallout and changing
gdb_demangle to also return this type. In one spot, std::string is
used to simplify some related code, and in another, an auto_obstack is
used to avoid manual management.
Regression tested on x86-64 Fedora 34.
Consider test-case gdb.trace/entry-values.exp with target board
unix/-fPIE/-pie.
Using this command we have an abbreviated version, and can see the correct
@entry values for foo:
...
$ gdb -q -batch outputs/gdb.trace/entry-values/entry-values \
-ex start \
-ex "break foo" \
-ex "set print entry-values both" \
-ex continue
Temporary breakpoint 1 at 0x679
Temporary breakpoint 1, 0x0000555555554679 in main ()
Breakpoint 2 at 0x55555555463e
Breakpoint 2, 0x000055555555463e in foo (i=0, i@entry=2, j=2, j@entry=3)
...
Now, let's try the same again, but run directly to foo rather than stopping at
main:
...
$ gdb -q -batch outputs/gdb.trace/entry-values/entry-values \
-ex "break foo" \
-ex "set print entry-values both" \
-ex run
Breakpoint 1 at 0x63e
Breakpoint 1, 0x000055555555463e in foo (i=0, i@entry=<optimized out>, \
j=2, j@entry=<optimized out>)
...
So, what explains the difference? Noteworthy, this is a dwarf assembly
test-case, with debug info for foo and bar, but not for main.
In the first case:
- we run to main
- this does not trigger expanding debug info, because there's none for main
- we set a breakpoint at foo
- this triggers expanding debug info. Relocated addresses are used in
call_site info (because the exec is started)
- we continue to foo, and manage to find the call_site info
In the second case:
- we set a breakpoint at foo
- this triggers expanding debug info. Unrelocated addresses are used in
call_site info (because the exec is not started)
- we run to foo
- this triggers objfile_relocate1, but it doesn't update the call_site
info addresses
- we don't manage to find the call_site info
We could fix this by adding the missing call_site relocation in
objfile_relocate1.
This solution however is counter-trend in the sense that we're trying to
work towards the situation where when starting two instances of an executable,
we need only one instance of debug information, implying the use of
unrelocated addresses.
So, fix this instead by using unrelocated addresses in call_site info.
Tested on x86_64-linux.
This fixes all remaining unix/-fno-PIE/-no-pie vs unix/-fPIE/-pie
regressions, like f.i. PR24892.

In commit b4c919f7525 "[gdb/symtab] Fix htab_find_slot call in
read_call_site_scope" , I removed the comment:
...
It must be the first field as we overload core_addr_hash and core_addr_eq for
it.
...
for field pc of struct call_site.
However, this was not tested, and when indeed moving field pc to the second
location, we run into a testsuite failure in gdb.trace/entry-values.exp.
This is caused by core_addr_eq (the eq_f function for the htab) being
called with a pointer to the pc field (as passed into htab_find_slot) and a
pointer to a hash table element. Now that pc is no longer the first field,
the pointer to hash table element no longer points to the pc field.
This could be fixed by simply reinstating the comment, but we're trying to
get rid of this kind of tricks that make refactoring more difficult.
Instead, fix this by:
- reverting commit b4c919f7525, apart from the comment removal, such that
we're passing a pointer to element to htab_find_slot
- updating the htab_find_slot call in compunit_symtab::find_call_site
in a similar manner
- adding a call_site_eq and call_site_hash, and using these in the hash table
instead of core_addr_eq and core_addr_hash.
Tested on x86_64-linux, both with and without a trigger patch that moves pc to
the second location in struct call_site.
String-like settings (var_string, var_filename, var_optional_filename,
var_string_noescape) currently take a pointer to a `char *` storage
variable (typically global) that holds the setting's value. I'd like to
"mordernize" this by changing them to use an std::string for storage.
An obvious reason is that string operations on std::string are often
easier to write than with C strings. And they avoid having to do any
manual memory management.
Another interesting reason is that, with `char *`, nullptr and an empty
string often both have the same meaning of "no value". String settings
are initially nullptr (unless initialized otherwise). But when doing
"set foo" (where `foo` is a string setting), the setting now points to
an empty string. For example, solib_search_path is nullptr at startup,
but points to an empty string after doing "set solib-search-path". This
leads to some code that needs to check for both to check for "no value".
Or some code that converts back and forth between NULL and "" when
getting or setting the value. I find this very error-prone, because it
is very easy to forget one or the other. With std::string, we at least
know that the variable is not "NULL". There is only one way of
representing an empty string setting, that is with an empty string.
I was wondering whether the distinction between NULL and "" would be
important for some setting, but it doesn't seem so. If that ever
happens, it would be more C++-y and self-descriptive to use
optional<string> anyway.
Actually, there's one spot where this distinction mattered, it's in
init_history, for the test gdb.base/gdbinit-history.exp. init_history
sets the history filename to the default ".gdb_history" if it sees that
the setting was never set - if history_filename is nullptr. If
history_filename is an empty string, it means the setting was explicitly
cleared, so it leaves it as-is. With the change to std::string, this
distinction doesn't exist anymore. This can be fixed by moving the code
that chooses a good default value for history_filename to
_initialize_top. This is ran before -ex commands are processed, so an
-ex command can then clear that value if needed (what
gdb.base/gdbinit-history.exp tests).
Another small improvement, in my opinion is that we can now easily
give string parameters initial values, by simply initializing the global
variables, instead of xstrdup-ing it in the _initialize function.
In Python and Guile, when registering a string-like parameter, we
allocate (with new) an std::string that is owned by the param_smob (in
Guile) and the parmpy_object (in Python) objects.
This patch started by changing all relevant add_setshow_* commands to
take an `std::string *` instead of a `char **` and fixing everything
that failed to build. That includes of course all string setting
variable and their uses.
string_option_def now uses an std::string also, because there's a
connection between options and settings (see
add_setshow_cmds_for_options).
The add_path function in source.c is really complex and twisted, I'd
rather not try to change it to work on an std::string right now.
Instead, I added an overload that copies the std:string to a `char *`
and back. This means more copying, but this is not used in a hot path
at all, so I think it is acceptable.

I noticed that pointer_type is declared in language.h and defined in
language.c. However, it really has to do with types, so it should
have been in gdbtypes.h all along.
This patch changes it to be a method on struct type. And, I went
through uses of TYPE_IS_REFERENCE and updated many spots to use the
new method as well. (I didn't update ones that were in arch-specific
code, as I couldn't readily test that.)
The compiler gives this warning when building symtab.c:
../../binutils-gdb/gdb/symtab.c:4247:28: warning: 'to_match' may be used uninitialized in this function [-Wmaybe-uninitialized]
This patch fixes the warning by adding a gdb_assert_not_reached.
Convert these three macros to methods of obj_section. The problem fixed
by the following patch is caused by an out of bound access of the
objfile::section_offsets vector. Since this is deep in macros, we don't
get a clear backtrace and it's difficult to debug. Changing that to
methods means we can step in them and break on them.
Because their implementation requires knowing about struct objfile, move
struct obj_section below struct objfile in objfiles.h.
The obj_section_offset was used in one place as an lvalue to set
offsets, in machoread.c. Replace that with a set_offset method.
Add the objfile::section_offset and objfile::set_section_offset methods
to improve encapsulation (reduce other objects poking into struct
objfile's internals).
gdb/ChangeLog:
* objfiles.h (struct obj_section): Move down.
<offset, set_offset, addr, endaddr>: New.
(obj_section_offset, obj_section_addr, obj_section_endaddr),
replace all users to use obj_section methods.
(struct objfile) <section_offset, set_section_offset>: New.

Currently the 'info sources' command lists all of the known source
files together, regardless of their source, e.g. here is a session
debugging a test application that makes use of a shared library:
(gdb) info sources
Source files for which symbols have been read in:
/tmp/info-sources/test.c, /usr/include/stdc-predef.h,
/tmp/info-sources/header.h, /tmp/info-sources/helper.c
Source files for which symbols will be read in on demand:
(gdb)
In this commit I change the format of the 'info sources' results so
that the results are grouped by the object file that uses that source
file. Here's the same session with the new output format:
(gdb) info sources
/tmp/info-sources/test.x:
/tmp/info-sources/test.c, /usr/include/stdc-predef.h,
/tmp/info-sources/header.h
/lib64/ld-linux-x86-64.so.2:
(Objfile has no debug information.)
system-supplied DSO at 0x7ffff7fcf000:
(Objfile has no debug information.)
/tmp/info-sources/libhelper.so:
/tmp/info-sources/helper.c, /usr/include/stdc-predef.h,
/tmp/info-sources/header.h
/lib64/libc.so.6:
(Objfile has no debug information.)
(gdb)
Notice that in the new output some source files are repeated,
e.g. /tmp/info-sources/header.h, as multiple objfiles use this source
file.
Further, some object files are tagged with the message '(Objfile has
no debug information.)', it is also possible to see the message '(Full
debug information has not yet been read for this file.)', which is
printed when some symtabs within an objfile have not yet been
expanded.
All of the existing regular expression based filtering still works.
An original version of this patch added the new format as an option to
'info sources', however, it was felt that the new layout was so much
better than the old style that GDB should just switch to the new
result format completely.

This commit adds a new option '--group-by-objfile' to the MI command
-file-list-exec-source-files. With this option the output format is
changed; instead of a single list of source files the results are now
a list of objfiles. For each objfile all of the source files
associated with that objfile are listed.
Here is an example of the new output format taken from the
documentation (the newlines are added just for readability):
-file-list-exec-source-files --group-by-objfile
^done,files=[{filename="/tmp/info-sources/test.x",
debug-info="fully-read",
sources=[{file="test.c",
fullname="/tmp/info-sources/test.c",
debug-fully-read="true"},
{file="/usr/include/stdc-predef.h",
fullname="/usr/include/stdc-predef.h",
debug-fully-read="true"},
{file="header.h",
fullname="/tmp/info-sources/header.h",
debug-fully-read="true"}]},
{filename="/lib64/ld-linux-x86-64.so.2",
debug-info="none",
sources=[]},
{filename="system-supplied DSO at 0x7ffff7fcf000",
debug-info="none",
sources=[]},
{filename="/tmp/info-sources/libhelper.so",
debug-info="fully-read",
sources=[{file="helper.c",
fullname="/tmp/info-sources/helper.c",
debug-fully-read="true"},
{file="/usr/include/stdc-predef.h",
fullname="/usr/include/stdc-predef.h",
debug-fully-read="true"},
{file="header.h",
fullname="/tmp/info-sources/header.h",
debug-fully-read="true"}]},
{filename="/lib64/libc.so.6",
debug-info="none",
sources=[]}]
In the above output the 'debug-info' field associated with each
objfile will have one of the values 'none', 'partially-read', or
'fully-read'. For example, /lib64/libc.so.6 has the value 'none',
this indicates that this object file has no debug information
associated with it, unsurprisingly then, the sources list of this
object file is empty.
An object file that was compiled with debug, for example
/tmp/info-sources/libhelper.so, has the value 'fully-read' above
indicating that this object file does have debug information, and the
information is fully read into GDB. At different times this field
might have the value 'partially-read' indicating that that the object
file has debug information, but it has not been fully read into GDB
yet.
Source files can appear at most once for any single objfile, but can
appear multiple times in total, if the same source file is part of
multiple objfiles, for example /tmp/info-sources/header.h in the above
output.
The new output format is hidden behind a command option to ensure that
the default output is unchanged, this ensures backward compatibility.
The behaviour of the CLI "info sources" command is unchanged after
this commit.

This commit extends the existing MI command
-file-list-exec-source-files to provide the same regular expression
based filtering that the equivalent CLI command "info sources"
provides.
The new command syntax is:
-file-list-exec-source-files [--basename | --dirname] [--] [REGEXP]
All options are optional, which ensures the command is backward
compatible.
As part of this work I have unified the CLI and MI code.
As a result of the unified code I now provide additional information
in the MI command output, there is now a new field 'debug-fully-read'
included with each source file. This field which has the values
'true' or 'false', indicates if the source file is from a compilation
unit that has had its debug information fully read. However, as this
is additional information, a well written front-end should just ignore
this field if it doesn't understand it, so things should still be
backward compatible.
gdb/ChangeLog:
* NEWS: Mention additions to -file-list-exec-source-files.
* mi/mi-cmd-file.c (print_partial_file_name): Delete.

In a future commit I'm going to be making some changes to the 'info
sources' command. While looking at the code I noticed that things
could be improved by making struct output_source_filename_data more
C++ like (private member variables, and more member functions).
That's what this commit does.
The 'info sources' filename filtering is split out into a separate
class in this commit. In a future commit this new filter
class (info_sources_filter) will move into the header file and be used
from the MI code.
There should be no user visible changes after this commit.

<output_source_filename_data>: New constructor. <regexp>: Delete,
this is now in info_sources_filter. <c_regexp>: Delete, this is

<filename_seen_cache>: Rename to m_filename_seen_cache, change
from being a pointer, to being an actual object. <first>: Rename

m_filename_seen_cache is no longer a pointer, and for other member

it's a member function and to take account of member variable
renaming.
(info_sources_command): Add a header comment, delete stack local
filename_seen_cache, initialization of output_source_filename_data
is now done by the constructor. Call print_header member function
instead of print_info_sources_header, call reset_output member
function instead of manually performing the reset.

Same idea as previous patch, but for add_alias_cmd. Remove the overload
that accepts the target command as a string (the target command name),
leaving only the one that takes the cmd_list_element.
gdb/ChangeLog:
* command.h (add_alias_cmd): Accept target as
cmd_list_element. Update callers.
Change-Id: I546311f411e9e7da9302322d6ffad4e6c56df266
Previously, the prefixname field of struct cmd_list_element was manually
set for prefix commands. This seems verbose and error prone as it
required every single call to functions adding prefix commands to
specify the prefix name while the same information can be easily
generated.
Historically, this was not possible as the prefix field was null for
many commands, but this was fixed in commit
3f4d92ebdf7f848b5ccc9e8d8e8514c64fde1183 by Philippe Waroquiers, so
we can rely on the prefix field being set when generating the prefix
name.
This commit also fixes a use after free in this scenario:
* A command gets created via Python (using the gdb.Command class).
The prefix name member is dynamically allocated.
* An alias to the new command is created. The alias's prefixname is set
to point to the prefixname for the original command with a direct
assignment.
* A new command with the same name as the Python command is created.
* The object for the original Python command gets freed and its
prefixname gets freed as well.
* The alias is updated to point to the new command, but its prefixname
is not updated so it keeps pointing to the freed one.

(add_abbrev_prefix_cmd): Ditto.
* cli/cli-decode.h (struct cmd_list_element): Replace the
prefixname member variable with a method which generates the
prefix name at runtime. Update all code reading the prefix
name to use the method, and remove all code setting it.
* python/py-cmd.c (cmdpy_destroyer): Remove code to free the
prefixname member as it's now a method.
(cmdpy_function): Determine if the command is a prefix by
looking at prefixlist, not prefixname.
Give a name to each observer, this will help produce more meaningful
debug message.
gdbsupport/ChangeLog:
* observable.h (class observable) <struct observer> <observer>:
Add name parameter.
<name>: New field.
<attach>: Add name parameter, update all callers.

This changes quick_symbol_functions::map_symbol_filenames to use a
function_view, and updates all the uses. It also changes the final
parameter to 'bool'. A couple of spots are further updated to use
operator() rather than a lambda.

* dwarf2/read.c
(dwarf2_base_index_functions::map_symbol_filenames): Update.
The current_top_target function is a hidden dependency on the current
inferior. Since I'd like to slowly move towards reducing our dependency
on the global current state, remove this function and make callers use
current_inferior ()->top_target ()
There is no expected change in behavior, but this one step towards
making those callers use the inferior from their context, rather than
refer to the global current inferior.
gdb/ChangeLog:
* target.h (current_top_target): Remove, make callers use the
current inferior instead.
* target.c (current_top_target): Remove.

This introduces wrappers for each function in quick_symbol_functions.
The wrappers are methods on objfile, and are defined in
symfile-debug.c, so that they can use the symfile_debug variable.
Places that call the quick functions are all updated to call these new
wrapper methods.

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.
