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 "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.

Introduce and use make_unique_xstrdup
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. gdb/ChangeLog: 2019-06-04 Pedro Alves <palves@redhat.com> * common/gdb_unique_ptr.h (make_unique_xstrdup): New. * ada-lang.c (catch_ada_completer): Use make_unique_xstrdup. * breakpoint.c (condition_completer): Likewise. * cli/cli-dump.c (scan_expression): Likewise. * common/filestuff.c (mkdir_recursive): Likewise. * common/gdb_tilde_expand.c (gdb_tilde_expand_up) * common/pathstuff.c (gdb_realpath, gdb_realpath_keepfile) (gdb_abspath): Likewise. * compile/compile-cplus-types.c (compile_cplus_instance::decl_name): Likewise. * completer.c (complete_explicit_location): (signal_completer, reg_or_group_completer_1): Likewise. * cp-support.c (cp_remove_params_if_any): Likewise. * fbsd-tdep.c (fbsd_core_vnode_path): Likewise. * guile/scm-safe-call.c (gdbscm_safe_eval_string): Likewise. * infcmd.c (strip_bg_char): Likewise. * linespec.c (copy_token_string): Likewise. * mi/mi-main.c (output_cores): Likewise. * psymtab.c (psymtab_search_name): * symfile.c (test_set_ext_lang_command): Likewise. * target.c (target_fileio_read_stralloc): Likewise. * tui/tui-regs.c (tui_reggroup_completer): Likewise. * value.c (complete_internalvar): Likewise. gdb/gdbserver/ChangeLog: 2019-06-04 Pedro Alves <palves@redhat.com> * server.c (captured_main): Use make_unique_xstrdup. |

Replace throw_exception with throw in some cases
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.

Make exceptions use std::string and be self-managing
This changes the exception's "message" member to be a shared_ptr wrapping a std::string. This allows removing the stack of exception messages, because now exceptions will self-destruct when needed.

Allow really large fortran array bounds: TYPE_LENGTH to ULONGEST
This series is revisit of Siddhesh Poyarekar's patch from back in 2012. The last status on the patch is in the following gdb-patches thread: https://sourceware.org/ml/gdb-patches/2012-08/msg00562.html It appears that Tom approved the patch, but Jan had some issues with a compiler error that made the test fail on -m32 test runs. He wrote up a hand-tweaked .S file to deal with it. Siddesh said he would update tests. Then nothing. Siddesh and Jan have both moved on since. The patch originally required a large precursor patch to work. I have whittled this down to/rewritten the bare minimum, and this first patch is the result, changing the type of TYPE_LENGTH to ULONGEST from unsigned int. The majority of the changes involve changing printf format strings to use %s and pulongest instead of %d. gdb/ChangeLog: * ada-lang.c (ada_template_to_fixed_record_type_1): Use %s/pulongest for TYPE_LENGTH instead of %d in format strings. * ada-typerint.c (ada_print_type): Likewise. * amd64-windows-tdep.c (amd64_windows_store_arg_in_reg): Likewise. * compile/compile-c-support.c (generate_register_struct): Likewise. * gdbtypes.c (recursive_dump_type): Likewise. * gdbtypes.h (struct type) <length>: Change type to ULONGEST. * m2-typeprint.c (m2_array): Use %s/pulongest for TYPE_LENGTH instead of %d in format strings. * riscv-tdep.c (riscv_type_alignment): Cast second argument to std::min to ULONGEST. * symmisc.c (print_symbol): Use %s/pulongest for TYPE_LENGTH instead of %d in format strings. * tracepoint.c (info_scope_command): Likewise. * typeprint.c (print_offset_data::update) (print_offset_data::finish): Likewise. * xtensa-tdep.c (xtensa_store_return_value) (xtensa_push_dummy_call): Likewise. |

Normalize include guards in gdb
While working on my other scripts to deal with gdb headers, I noticed
that some files were missing include guards. I wrote a script to add
the missing ones, but found that using the obvious names for the
guards ran into clashes -- for example, gdb/nat/linux-nat.h used
"LINUX_NAT_H", but this was also the script's choice for
gdb/linux-nat.h.
So, I changed the script to normalize all include guards in gdb. This
patch is the result.
As usual the script is available here:
https://github.com/tromey/gdb-refactoring-scripts
Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the
buildbot.

Remove a comment in compile/compile-cplus-types.c
The include sorter can't handle multi-line comments on the same line as a #include. This patch removes the only such comment. In general I think these sorts of comments do not provide much value: more often than not, I find that the comment is obsolete in one way or another, and so the include sorter removes them in most cases. gdb/ChangeLog 2019-01-22 Tom Tromey <tom@tromey.com> * compile/compile-cplus-types.c: Remove a comment by #include. |

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. |

Use gdb:array_view in call_function_by_hand & friends
This replaces a few uses of pointer+length with gdb::array_view, in call_function_by_hand and related code. Unfortunately, due to -Wnarrowing, there are places where we can't brace-initialize an gdb::array_view without an ugly-ish cast. To avoid the cast, this patch introduces a gdb::make_array_view function. Unit tests included. This patch in isolation may not look so interesting, due to gdb::make_array_view uses, but I think it's still worth it. Some of the gdb::make_array_view calls disappear down the series, and others could be eliminated with more (non-trivial) gdb::array_view detangling/conversion (e.g. code around eval_call). See this as a "we have to start somewhere" patch. gdb/ChangeLog: 2018-11-21 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_evaluate_subexp): Adjust to pass an array_view. * common/array-view.h (make_array_view): New. * compile/compile-object-run.c (compile_object_run): Adjust to pass an array_view. * elfread.c (elf_gnu_ifunc_resolve_addr): Adjust. * eval.c (eval_call): Adjust to pass an array_view.

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.

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.

Fix compile-cplus-types.c build errors
I see these errors when building with clang:
CXX compile/compile-cplus-types.o
/home/emaisin/src/binutils-gdb/gdb/compile/compile-cplus-types.c:306:56: error: cannot pass non-trivial object of type 'compile_scope' to variadic function; expected type from format string was 'void *' [-Wnon-pod-varargs]

~~ ^~~~~~~
/home/emaisin/src/binutils-gdb/gdb/compile/compile-cplus-types.c:1058:13: error: comparison of two values with different enumeration types ('enum_flags<gcc_cp_qualifiers>::enum_type' (aka 'gcc_cp_qualifiers') and 'gcc_cp_ref_qualifiers') [-Werror,-Wenum-compare]

~~~~~ ^ ~~~~~~~~~~~~~~~~~~~~
Fix the first one by using host_address_to_string.
Fix the second one by comparing to 0 instead. I think the current
comparison simply uses the wrong enum type. Comparing to 0 seems like
the right thing to do, because we want to check whether any flags are
specified.
gdb/ChangeLog:
* compile/compile-cplus-types.c

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.

Change compile_instance/compile_c_instance into classes
This patch changes structs compile_instance and compile_c_instance into
classes.
Because of the nature of the change, there are a number of unavoidably
mechanical changes buried in here, such as turning variable access of the
POD struct into method calls, removing the struct keyword, and changing
access of the plugin from "c_plugin->operation()" to
"plugin ().operation ()".
There is one "non-trivial" change associated with this patch, though.
The type cache and symbol error maps have been moved into the base class,
believing these facilities would be used other language implementations.
[They are indeed re-used by C++.]
gdb/ChangeLog:
* compile/compile-c-support.c (c_get_compile_context): Use `new'
instead of `new_compile_instance'.
* compile/compile-c-symbols.c (compile_instance::insert_symbol_error):

If the symbol error map is not initialized, create it.
(generate_c_for_for_one_symbol): Do not check/initialize
the symbol error map.
* compile/compile-c-types.c (compile_c_instance): Make a class.

Add a C++ wrapper for GCC C plug-in
This patch introduces a new class which wraps the GCC C compile plug-in.
It is a little unfortunate that this all happened in between the time that
GCC moved to C++ and GDB moved to C++, leaving us with an ABI promise to
support a C-like interface. The hope is to isolate GDB from some of this
should it change in the future.
Broadly, what this does is replace calls like:
C_CTX (context)->c_ops->operation (C_CTX (context), ...);
with calls that now look like:
context->c_plugin->operation (...);
This API will be further refined in following patches when struct
compile_instance/compile_c_instance are changed into classes.
gdb/ChangeLog:
* Makefile.in (HFILES_NO_SRCDIR): Add compile/gcc-c-plugin.h.
* compile/compile-c-types.c: Define GCC_METHODN macros and include
gcc-c-fe.def to define C plugin.
(delete_instance): Delete `c_plugin'.
(new_compile_instance): Initialize `c_plugin'.
* compile/compile-c.h: Include gcc_c_plugin.h.
(struct compile_c_instance) <c_plugin>: New member.
* gcc-c-plugin.h: New file.
Update all callers with API change.

Use thread_info and inferior pointers more throughout
This is more preparation bits for multi-target support. In a multi-target scenario, we need to address the case of different processes/threads running on different targets that happen to have the same PID/PTID. E.g., we can have both process 123 in target 1, and process 123 in target 2, while they're in reality different processes running on different machines. Or maybe we've loaded multiple instances of the same core file. Etc. To address this, in my WIP multi-target branch, threads and processes are uniquely identified by the (process_stratum target_ops *, ptid_t) and (process_stratum target_ops *, pid) tuples respectively. I.e., each process_stratum instance has its own thread/process number space. As you can imagine, that requires passing around target_ops * pointers in a number of functions where we're currently passing only a ptid_t or an int. E.g., when we look up a thread_info object by ptid_t in find_thread_ptid, the ptid_t alone isn't sufficient. In many cases though, we already have the thread_info or inferior pointer handy, but we "lose" it somewhere along the call stack, only to look it up again by ptid_t/pid. Since thread_info or inferior objects know their parent target, if we pass around thread_info or inferior pointers when possible, we avoid having to add extra target_ops parameters to many functions, and also, we eliminate a number of by ptid_t/int lookups. So that's what this patch does. In a bit more detail: - Changes a number of functions and methods to take a thread_info or inferior pointer instead of a ptid_t or int parameter. - Changes a number of structure fields from ptid_t/int to inferior or thread_info pointers. - Uses the inferior_thread() function whenever possible instead of inferior_ptid. - Uses thread_info pointers directly when possible instead of the is_running/is_stopped etc. routines that require a lookup. - A number of functions are eliminated along the way, such as: int valid_gdb_inferior_id (int num); int pid_to_gdb_inferior_id (int pid); int gdb_inferior_id_to_pid (int num); int in_inferior_list (int pid); - A few structures and places hold a thread_info pointer across inferior execution, so now they take a strong reference to the (refcounted) thread_info object to avoid the thread_info pointer getting stale. This is done in enable_thread_stack_temporaries and in the infcall.c code. - Related, there's a spot in infcall.c where using a RAII object to handle the refcount would be handy, so a gdb::ref_ptr specialization for thread_info is added (thread_info_ref, in gdbthread.h), along with a gdb_ref_ptr policy that works for all refcounted_object types (in common/refcounted-object.h). gdb/ChangeLog: 2018-06-21 Pedro Alves <palves@redhat.com> * ada-lang.h (ada_get_task_number): Take a thread_info pointer instead of a ptid_t.

Use counted_command_line everywhere
Currently command lines are reference counted using shared_ptr only when attached to breakpoints. This patch changes gdb to use shared_ptr in commands as well. This allows for the removal of copy_command_lines. Note that the change to execute_user_command explicitly makes a new reference to the command line. This will be used in a later patch. This simplifies struct command_line based on the observation that a given command can have at most two child bodies: an "if" can have both "then" and "else" parts. Perhaps the names I've chosen for the replacements here are not very good -- your input requested. ChangeLog 2018-05-04 Tom Tromey <tom@tromey.com> * tracepoint.c (all_tracepoint_actions): Rename from all_tracepoint_actions_and_cleanup. Change return type.

Add libcc1 v1 compatibility to C compile feature
This patch adds v1 compatibiltiy to the C compile feature. The only change in v1 concerns the handling of integer types, which permits GDB to specify the built-in name for the type. As far as I know, the C frontend is still on v0, so this patch is purely precautionary. [By default C++ compile uses the equivalent of the C frontend's int_type and float_type (aka the "v1" versions).] gdb/ChangeLog: * compile/compile-c-types.c (convert_int, convert_float): Update for C FE v1. |

Create new common/pathstuff.[ch]
This commit moves the path manipulation routines found on utils.c to a new common/pathstuff.c, and updates the Makefile.in's accordingly. The routines moved are "gdb_realpath", "gdb_realpath_keepfile" and "gdb_abspath". This will be needed because gdbserver will have to call "gdb_abspath" on my next patch, which implements a way to expand the path of the inferior provided by the user in order to allow specifying just the binary name when starting gdbserver, like: $ gdbserver :1234 a.out With the recent addition of the startup-with-shell feature on gdbserver, this scenario doesn't work anymore if the user doesn't have the current directory listed in the PATH variable. I had to do a minor adjustment on "gdb_abspath" because we don't have access to "tilde_expand" on gdbserver, so now the function is using "gdb_tilde_expand" instead. Otherwise, the code is the same. Regression tested on the BuildBot, without regressions. gdb/ChangeLog: 2018-02-28 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (COMMON_SFILES): Add "common/pathstuff.c". (HFILES_NO_SRCDIR): Add "common/pathstuff.h". * auto-load.c: Include "common/pathstuff.h". * common/common-def.h (current_directory): Move here. * common/gdb_tilde_expand.c (gdb_tilde_expand_up): New function. * common/gdb_tilde_expand.h (gdb_tilde_expand_up): New prototype. * common/pathstuff.c: New file. * common/pathstuff.h: New file. * compile/compile.c: Include "common/pathstuff.h". * defs.h (current_directory): Move to "common/common-defs.h". * dwarf2read.c: Include "common/pathstuff.h". * exec.c: Likewise. * guile/scm-safe-call.c: Likewise. * linux-thread-db.c: Likewise. * main.c: Likewise. * nto-tdep.c: Likewise. * objfiles.c: Likewise. * source.c: Likewise. * symtab.c: Likewise. * utils.c: Include "common/pathstuff.h".

Fix warning on gdb/compile/compile.c (C++-ify "triplet_rx")
This fixes a GCC warning that happens when compiling
gdb/compile/compile.c on some GCC versions (e.g., "gcc (GCC) 7.2.1
20180104 (Red Hat 7.2.1-6)"):
../../gdb/compile/compile.c: In function 'void eval_compile_command(command_line*, const char*, compile_i_scope_types, void*)':
../../gdb/compile/compile.c:548:19: warning: 'triplet_rx' may be used uninitialized in this function [-Wmaybe-uninitialized]
error_message = compiler->fe->ops->set_arguments_v0 (compiler->fe, triplet_rx,
~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
argc, argv);
~~~~~~~~~~~
../../gdb/compile/compile.c:466:9: note: 'triplet_rx' was declared here
char *triplet_rx;
^~~~~~~~~~
It's a simple patch that converts "triplet_rx" from "char *" to
"std::string", thus guaranteeing that it will be always initialized.
I've regtested this patch and did not find any regressions. OK to
apply on both master and 8.1 (after creating a bug for it)?
gdb/ChangeLog:
2018-01-17 Sergio Durigan Junior <sergiodj@redhat.com>
* compile/compile.c (compile_to_object): Convert "triplet_rx"
to "std::string".
