gdb: move struct ui and related things to ui.{c,h}
I'd like to move some things so they become methods on struct ui. But
first, I think that struct ui and the related things are big enough to
deserve their own file, instead of being scattered through top.{c,h} and
event-top.c.

gdbsupport: make gdb_abspath return an std::string
I'm trying to switch these functions to use std::string instead of char arrays, as much as possible. Some callers benefit from it (can avoid doing a copy of the result), while others suffer (have to make one more copy). Change-Id: Iced49b8ee2f189744c5072a3b217aab5af17a993 |

gdb: make string-like set show commands use std::string variable
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.

Introduce scoped_restore_signal
We currently have scoped_restore_sigttou and scoped_restore_sigpipe doing basically the same thing -- temporarily ignoring a specific signal. This patch introduce a scoped_restore_signal type that can be used for both. This will become more important for the next patch which changes how the signal-ignoring is implemented. scoped_restore_sigpipe is a straight alias to scoped_restore_signal<SIGPIPE> on systems that define SIGPIPE, and an alias to scoped_restore_signal_nop (a no-op version of scoped_restore_signal) otherwise. scoped_restore_sigttou is not a straight alias because it wants to check the job_control global. gdb/ChangeLog: yyyy-mm-dd Pedro Alves <pedro@palves.net> * gdbsupport/scoped_ignore_signal.h: New. * compile/compile.c: Include gdbsupport/scoped_ignore_signal.h instead of <signal.h>.

gdb: make add_com_alias accept target as a cmd_list_element
The alias creation functions currently accept a name to specify the target command. They pass this to add_alias_cmd, which needs to lookup the target command by name. Given that: - We don't support creating an alias for a command before that command exists. - We always use add_info_alias just after creating that target command, and therefore have access to the target command's cmd_list_element. ... change add_com_alias to accept the target command as a cmd_list_element (other functions are done in subsequent patches). This ensures we don't create the alias before the target command, because you need to get the cmd_list_element from somewhere when you call the alias creation function. And it avoids an unecessary command lookup. So it seems better to me in every aspect. gdb/ChangeLog: * command.h (add_com_alias): Accept target as cmd_list_element. Update callers.

gdb: generate the prefix name for prefix commands on demand
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

Don't pass empty options to GCC
On aarch64-linux, I noticed the compile command didn't work at all. It always gave the following error: aarch64-linux-gnu-g++: error: : No such file or directory Turns out we're passing an empty argv entry to GCC (because aarch64 doesn't have a -m64 option), and GCC's behavior is to think that is a file it needs to open. One can reproduce it like so: gcc "" "" "" "" gcc: error: : No such file or directory gcc: error: : No such file or directory gcc: error: : No such file or directory gcc: error: : No such file or directory gcc: fatal error: no input files compilation terminated. The solution is to check for an empty string and skip adding that to argv. Regression tested on aarch64-linux/Ubuntu 18.04/20.04. gdb/ChangeLog: 2021-03-29 Luis Machado <luis.machado@linaro.org> * compile/compile.c (get_args): Don't add empty argv entries. |

Avoid crash in compile_to_object
PR 23672 points out a crash in compile_to_object. This crash came in during a C++-ization. This patch avoids the crash. The PR also points out another weird behavior in this code, but that one requires some setup that I don't have here, and it seems to date back to the introduction of the compile feature. So, it isn't addressed here. I will leave the PR open so this bug isn't forgotten. gdb/ChangeLog 2021-01-09 Tom Tromey <tom@tromey.com> PR compile/23672 * compile/compile.c (compile_to_object): Avoid crash when osabi_triplet_regexp returns NULL. |

gdb: Convert la_name and la_natural_name to methods
Convert the two language_data member variables la_name and la_natural_name to virtual methods in language_defn struct called name and natural_name respectively. The virtual methods in the language_defn base class are pure virtual, as every language must implement these, and as every language has a unique name there's no sensible default here. Given that every language must implement these methods I did wonder about making this data passed into the base class constructor, but in the end I went with the virtual method approach. I'm open to changing this approach if people prefer the constructor approach. During updating the calls to language_defn::name I found in add_set_language_command a place where we took la_name and then capitalised the first letter to create a language name that could be used in the documentation string. I replaced this with a use of natural_name instead as this seemed a better choice, in most cases this will make no difference, as for most languages the natural_name is just the name with the first character in upper case, but for some languages, for example 'Open-CL' and 'Objective-C' this is not the case. In the case of asm_language the name is 'asm', while the natural_name was previously 'assembly'. I changed the natural name to 'Assembly', this makes the documentation string case above cleaner, however, this will change the MI output for -var-info-expression, where the 'lang' field will change from 'assembly' to 'Assembly'. It is possible this could be a breaking change if a front-end is relying on the existing name. gdb/ChangeLog: * ada-lang.c (ada_language_data): Remove la_name and la_natural_name initializers.

Change gcc_target_options to return std::string
This patch was inspired by a recent review that recommended using std::string in a new implementation of the gcc_target_options gdbarch function. It changes this function to return std::string rather than an ordinary xmalloc'd string. I believe this caught a latent memory leak in compile.c:get_args. Tested on x86-64 Fedora 29. gdb/ChangeLog 2019-10-15 Tom Tromey <tromey@adacore.com> * gdbarch.h, gdbarch.c: Rebuild. * gdbarch.sh (gcc_target_options): Change return type to std::string. * compile/compile.c (get_args): Update. * nios2-tdep.c (nios2_gcc_target_options): Return std::string. * arm-linux-tdep.c (arm_linux_gcc_target_options): Return std::string. * aarch64-linux-tdep.c (aarch64_linux_gcc_target_options): Return std::string. * arch-utils.c (default_gcc_target_options): Return std::string. * arch-utils.h (default_gcc_target_options): Return std::string. * s390-tdep.c (s390_gcc_target_options): Return std::string.

Make first and last lines of 'command help documentation' consistent.
With this patch, the help docs now respect 2 invariants: * The first line of a command help is terminated by a '.' character. * The last character of a command help is not a newline character. Note that the changes for the last invariant were done by Tom, as part of : [PATCH] Remove trailing newlines from help text https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html but some occurrences have been re-introduced since then. Some help docs had to be rephrased/restructured to respect the above invariants. Before this patch, print_doc_line was printing the first line of a command help documentation, but stopping at the first '.' or ',' character. This was giving inconsistent results : * The first line of command helps was sometimes '.' terminated, sometimes not. * The first line of command helps was not always designed to be readable/understandable/unambiguous when stopping at the first '.' or ',' character. This e.g. created the following inconsistencies/problems: < catch exception -- Catch Ada exceptions < catch handlers -- Catch Ada exceptions < catch syscall -- Catch system calls by their names < down-silently -- Same as the `down' command while the new help is: > catch exception -- Catch Ada exceptions, when raised. > catch handlers -- Catch Ada exceptions, when handled. > catch syscall -- Catch system calls by their names, groups and/or numbers. > down-silently -- Same as the `down' command, but does not print anything. Also, the command help doc should not be terminated by a newline character, but this was not respected by all commands. The cli-option -OPT framework re-introduced some occurences. So, the -OPT build help framework was changed to not output newlines at the end of %OPTIONS% replacement. This patch changes the help documentations to ensure the 2 invariants given above. It implied to slightly rephrase or restructure some help docs. Based on the above invariants, print_doc_line (called by 'apropos' and 'help' commands to print the first line of a command help) now outputs the full first line of a command help. This all results in a lot of small changes in the produced help docs. There are less code changes than changes in the help docs, as a lot of docs are produced by some code (e.g. the remote packet usage settings). gdb/ChangeLog 2019-08-07 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-decode.h (print_doc_line): Add for_value_prefix argument. * cli/cli-decode.c (print_doc_line): Likewise.

Use _() in calls to build_help
Currently some code in gdb uses build_help with N_(), like:
static const std::string compile_print_help
= gdb::option::build_help (N_("\
I believe this is incorrect. The N_ macro is used to mark text that
should end up in the message catalog, but which will be translated by
a later call to gettext.
However, in this case, there is no later call to gettext, so (if gdb
had translations), this text would remain untranslated.
Instead, I think using the ordinary _() macro is correct here.
Translators will have to know to preserve "%OPTIONS%" in the text --
but that seems both unavoidable and fine.
Tested by rebuilding as there's not much else to do.

Rename common to gdbsupport
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. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

Fix gdb build with -std=gnu++11
The options framework series broken the build with gcc 4.8, or any
other compiler were we end up forcing -std=gnu++11, causing errors
like these:
../../binutils-gdb/gdb/compile/compile.c: In function gdb::option::option_def_group make_compile_options_def_group(compile_options*):
../../binutils-gdb/gdb/compile/compile.c:266:44: error: could not convert (const gdb::option::option_def*)(& compile_command_option_defs) from const gdb::option::option_def* to gdb::array_view<const gdb::option::option_def>
return {compile_command_option_defs, opts};
^
CXX copying.o
../../binutils-gdb/gdb/compile/compile.c:267:1: error: control reaches end of non-void function [-Werror=return-type]
}
^
This is a C++11 vs C++14 difference -- C++14 relaxed the rules for
eliding braces.
This commit fixes it by adding the missing (in C++11) braces. Tested
with g++ 4.8.
gdb/ChangeLog:
2019-06-13 Pedro Alves <palves@redhat.com>
* compile/compile.c (make_compile_options_def_group): Add braces
around array_view initializer.
* thread.c (make_thread_apply_all_options_def_group)
(make_thread_apply_all_options_def_group): Likewise.

Migrate rest of compile commands to new options framework
As I was in the neighbourhood, I converted the other "compile"
subcommands to the new options framework too. Specifically, "compile
code" and "compile file".
The user-visible changes are:
- All abbreviations of "-raw" are accepted now, instead of just -r.
Obviously that means "-ra" is now accepted.
- Option completion now works.
- "compile file" did not have a completer yet, and now it knows to
complete on filenames.
- You couldn't use "compile file" with a file named "-something".
You can now, with "compile file -- -something".
gdb/ChangeLog:
2019-06-13 Pedro Alves <palves@redhat.com>
* compile/compile.c (struct compile_options): New.
(compile_flag_option_def, compile_command_option_defs)
(make_compile_options_def_group): New.
(compile_file_command): Handle options with
gdb::option::process_options.
(compile_file_command_completer): New function.
(compile_code_command): Handle options with
gdb::option::process_options.
(compile_code_command_completer): New function.
(_initialize_compiler): Install completers for "compile code" and
"compile file". Mention available options in "compile code" and
"compile code"'s help.
* completer.c (advance_to_completion_word): New, factored out from
...
(advance_to_expression_complete_word_point): ... this.
(advance_to_filename_complete_word_point): New.
* completer.h (advance_to_filename_complete_word_point): New
declaration.
gdb/testsuite/ChangeLog:

Make "print" and "compile print" support -OPT options
This patch adds support for "print -option optval --", etc.
Likewise for "compile print".
We'll get:
~~~~~~
(gdb) help print
Print value of expression EXP.
Usage: print [[OPTION]... --] [/FMT] [EXP]
Options:
-address [on|off]
Set printing of addresses.
-array [on|off]
Set pretty formatting of arrays.
-array-indexes [on|off]
Set printing of array indexes.
-elements NUMBER|unlimited
Set limit on string chars or array elements to print.
"unlimited" causes there to be no limit.
-max-depth NUMBER|unlimited
Set maximum print depth for nested structures, unions and arrays.
When structures, unions, or arrays are nested beyond this depth then they
will be replaced with either '{...}' or '(...)' depending on the language.
Use "unlimited" to print the complete structure.
-null-stop [on|off]
Set printing of char arrays to stop at first null char.
-object [on|off]
Set printing of C++ virtual function tables.
-pretty [on|off]
Set pretty formatting of structures.
-repeats NUMBER|unlimited
Set threshold for repeated print elements.
"unlimited" causes all elements to be individually printed.
-static-members [on|off]
Set printing of C++ static members.
-symbol [on|off]
Set printing of symbol names when printing pointers.
-union [on|off]
Set printing of unions interior to structures.
-vtbl [on|off]
Set printing of C++ virtual function tables.
Note: because this command accepts arbitrary expressions, if you
specify any command option, you must use a double dash ("--")
to mark the end of option processing. E.g.: "print -o -- myobj".
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I want to highlight the comment above about "--".
At first, I thought we could make the print command parse the options,
and if the option wasn't recognized, fallback to parsing as an
expression. Then, if the user wanted to disambiguate, he'd use the
"--" option delimiter. For example, if you had a variable called
"object" and you wanted to print its negative, you'd have to do:
(gdb) print -- -object
After getting that working, I saw that gdb.pascal/floats.exp
regressed, in these tests:
gdb_test "print -r" " = -1\\.2(499.*|5|500.*)"
gdb_test "print -(r)" " = -1.2(499.*|5|500.*)"
gdb_test "print -(r + s)" " = -3\\.4(499.*|5|500.*)"
It's the first one that I found most concerning. It regressed because
"-r" is the abbreviation of "-raw". I realized then that the behavior
change was a bit risker than I'd like, considering scripts, wrappers
around gdb, etc., and even user expectation. So instead, I made the
print command _require_ the "--" options delimiter if you want to
specify any option. So:
(gdb) print -r
is parsed as an expression, and
(gdb) print -r --
is parsed as an option.
I noticed that that's also what lldb's expr (the equivalent of print)
does to handle the same problem.
Going back the options themselves, note that:
- you can shorten option names, as long as unambiguous.
- For boolean options, 0/1 stand for off/on.
- For boolean options, "true" is implied.
So these are all equivalent:
(gdb) print -object on -static-members off -pretty on -- foo
(gdb) print -object -static-members off -pretty -- foo
(gdb) print -object -static-members 0 -pretty -- foo
(gdb) print -o -st 0 -p -- foo
TAB completion is fully supported:
(gdb) p -[TAB]
-address -elements -pretty -symbol
-array -null-stop -repeats -union
-array-indexes -object -static-members -vtbl
Note that the code is organized such that some of the options and the
"set/show" commands code is shared. In particular, the "print"
options and the corresponding "set print" commands are defined with
the same structures. The commands are installed with the
gdb::option::add_setshow_cmds_for_options function.

Update copyright year range in all GDB files.
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. |

Simple -Wshadow=local fixes
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. gdb/ChangeLog 2018-10-04 Tom Tromey <tom@tromey.com> * ctf.c (SET_ARRAY_FIELD): Rename "u32". * p-valprint.c (pascal_val_print): Split inner "i" variable. * xtensa-tdep.c (xtensa_push_dummy_call): Declare "i" in loop header. * xstormy16-tdep.c (xstormy16_push_dummy_call): Declare "val" in more inner scope. * xcoffread.c (read_xcoff_symtab): Rename inner "symbol". * varobj.c (varobj_update): Rename inner "newobj", "type_changed". * valprint.c (generic_emit_char): Rename inner "buf". * valops.c (find_overload_match): Rename inner "temp".

compile: Remove non-const reference parameters
As mentioned here: https://sourceware.org/gdb/wiki/Internals%20GDB-C-Coding-Standards#Avoid_non-const_reference_parameters.2C_use_pointers_instead we prefer to avoid non-const references. This patch changes the non-const references I could find in the compile/ directory, either by making them rvalue-reference (&&) or changing them to pointers. I'd say all the changes are pretty obvious, except the one in compile_cplus_instance::enter_scope which might require more attention. gdb/ChangeLog: * compile/compile-c.h (generate_c_for_variable_locations): Change reference to pointer. * compile/compile-c-support.c (compile_program) <compute>: Likewise. * compile/compile-c-symbols.c (generate_vla_size): Likewise.

C++ compile support
This patch adds *basic* support for C++ to the compile feature. It does
most simple type conversions, including everything that C compile does and
your basic "with-classes" type of C++.
I've written a new compile-support.exp support file which adds a new test
facility for automating and simplifying "compile print" vs "compile code"
testing. See testsuite/lib/compile-support.exp and CompileExpression
for more on that. The tests use this facility extensively.
This initial support has several glaring omissions:
- No template support at all
I have follow-on patches for this, but they add much complexity
to this "basic" support. Consequently, they will be submitted separately.
- Cannot print functions
The code template needs tweaking, and I simply haven't gotten to it yet.
- So-called "special function" support is not included
Using constructors, destructors, operators, etc will not work. I have
follow-on patches for that, but they require some work because of the
recent churn in symbol searching.
- There are several test suite references to "compile/1234" bugs.
I will file bugs and update the test suite's bug references before pushing
these patches.
The test suite started as a copy of the original C-language support, but
I have written tests to exercise the basic functionality of the plug-in.
I've added a new option for outputting debug messages for C++ type-conversion
("debug compile-cplus-types").

Use BLOCK_ENTRY_PC in place of most uses of BLOCK_START
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. I'm posting it as a separate patch. gdb/ChangeLog: * ax-gdb.c (gen_var_ref): Use BLOCK_ENTRY_PC in place of BLOCK_START. * blockframe.c (get_pc_function_start): Likewise. * compile/compile-c-symbols.c (convert_one_symbol): Likewise.
