2019-08-07Make struct frame_arg self-managingTom Tromey1-5/+1
This changes struct frame_arg to be self-managing and then fixes the various users. Tested by the buildbot. gdb/ChangeLog 2019-08-07 Tom Tromey <tromey@adacore.com> * stack.c (print_frame_arg, read_frame_local, read_frame_arg) (print_frame_args): Update. * python/py-framefilter.c (py_print_single_arg, enumerate_args): Update. * mi/mi-cmd-stack.c (list_arg_or_local): Update. * frame.h (struct frame_arg): Add initializers. <error>: Now a unique_xmalloc_ptr.
2019-08-06Add more styling to "disassemble"Tom Tromey1-0/+5
This adds more styling to the disassemble command. In particular, addresses and function names in the disassembly are now styled. This required fixing a small latent bug in set_output_style. This function always passed NULL to emit_style_escape; but when writing to a file other than gdb_stdout, it should emit the style escape directly. (FWIW this is another argument for better integrating the pager with ui_file and getting rid of this entire layer.) gdb/ChangeLog 2019-08-06 Tom Tromey <tom@tromey.com> * utils.c (set_output_style): Sometimes pass stream to emit_style_escape. * ui-out.h (class ui_out) <can_emit_style_escape>: Declare. * record-btrace.c (btrace_insn_history): Update. * mi/mi-out.h (class mi_ui_out) <can_emit_style_escape>: New method. * disasm.h (gdb_pretty_print_disassembler): Add uiout parameter.

(dump_insns): Update. * cli-out.h (class cli_ui_out) <can_emit_style_escape>: Declare. * cli-out.c (cli_ui_out::can_emit_style_escape): New method. gdb/testsuite/ChangeLog 2019-08-06 Tom Tromey <tom@tromey.com> * gdb.base/style.exp: Add disassemble test. * gdb.base/style.c (some_called_function): New function. (main): Use it.
2019-07-17Rename field_int to field_signedTom Tromey8-50/+50
This renames ui_out::field_int to field_signed, and field_fmt_int to field_fmt_signed; and changes the type of the "value" parameter from int to LONGEST.

2019-07-15Fix a FIXME in mi-out.cTom Tromey1-4/+1
This removes a FIXME comment from mi_ui_out::do_field_int, by replacing a printf with a use of plongest. 2019-07-15 Tom Tromey <tromey@adacore.com> * mi/mi-out.c (mi_ui_out::do_field_int): Use plongest.
2019-07-15Introduce field_unsignedTom Tromey2-0/+13
This adds field_unsigned and changes various places using field_fmt with "%u" to use this instead. This also replaces an existing equivalent helper function in record-btrace.c. 2019-07-15 Tom Tromey <tromey@adacore.com> * mi/mi-out.h (class mi_ui_out) <do_field_unsigned>: Declare. * mi/mi-out.c (mi_ui_out::do_field_unsigned): New method. * cli-out.h (class cli_ui_out) <do_field_unsigned>: Declare. * cli-out.c (cli_ui_out::do_field_int): New method. * ui-out.c (ui_out::field_unsigned): New method. * symfile.c (generic_load): Use field_unsigned.

2019-07-15Use field_string in more placesTom Tromey2-2/+2
This replaces uses of field_fmt with a "%s" format string to use field_string instead. Also, one use of "%9lx" is replaced with a call to phex_nz; the '9' is dropped as it is implicit in the field width. 2019-07-15 Tom Tromey <tromey@adacore.com> * mi/mi-main.c (list_available_thread_groups): Use field_string. * mi/mi-interp.c (mi_memory_changed): Use field_string. * target.c (flash_erase_command): Use field_string. * infrun.c (print_signal_received_reason): Use field_string. * i386-tdep.c (i386_mpx_print_bounds): Use field_string. * breakpoint.c (maybe_print_thread_hit_breakpoint): Use field_string. * ada-tasks.c (print_ada_task_info): Use field_string.
2019-07-09Rename common to gdbsupportTom Tromey7-11/+11
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.

2019-06-15gdb/mi: New commands to catch C++ exceptionsAndrew Burgess3-0/+80
Adds some MI commands to catch C++ exceptions. The new commands are -catch-throw, -catch-rethrow, and -catch-catch, these all correspond to the CLI commands 'catch throw', 'catch rethrow', and 'catch catch'. Each MI command takes two optional arguments, '-t' has the effect of calling 'tcatch' instead of 'catch', for example: (gdb) -catch-throw -t Is the same as: (gdb) tcatch throw There is also a '-r REGEXP' argument that can supply a regexp to match against the exception type, so: (gdb) -catch-catch -r PATTERN Is the same as: (gdb) catch catch PATTERN The change in print_mention_exception_catchpoint might seem a little strange; changing the output from using ui_out::field_int and ui_out::text to using ui_out::message. The print_mention_exception_catchpoint is used as the 'print_mention' method for the exception catchpoint breakpoint object. Most of the other 'print_mention' methods (see breakpoint.c) use either printf_filtered, of ui_out::message. Using field_int was causing an unexpected field to be added to the MI output. Here's the output without the change in print_mention_exception_catchpoint: (gdb) -catch-throw ^done,bkptno="1",bkpt={number="1",type="breakpoint",disp="keep", enabled="y",addr="0x00000000004006c0", what="exception throw",catch-type="throw", thread-groups=["i1"],times="0"} Notice the breakpoint number appears in both the 'bkptno' field, and the 'number' field within the 'bkpt' tuple. Here's the output with the change in print_mention_exception_catchpoint: (gdb) -catch-throw ^done,bkpt={number="1",type="breakpoint",disp="keep", enabled="y",addr="0x00000000004006c0", what="exception throw",catch-type="throw", thread-groups=["i1"],times="0"} gdb/ChangeLog: * NEWS: Mention new MI commands. * break-catch-throw.c (enum exception_event_kind): Move to breakpoint.h.

2019-06-13Make "backtrace" support -OPT optionsPedro Alves1-8/+15
This adds support for comand options to the "backtrace" command. We'll get: (gdb) bt - -entry-values -hide -past-main -frame-arguments -no-filters -raw-frame-arguments -full -past-entry ~~~~ (gdb) help backtrace Print backtrace of all stack frames, or innermost COUNT frames. Usage: backtrace [OPTION]... [QUALIFIER]... [COUNT | -COUNT] Options: -entry-values no|only|preferred|if-needed|both|compact|default Set printing of function arguments at function entry GDB can sometimes determine the values of function arguments at entry, in addition to their current values. This option tells GDB whether to print the current value, the value at entry (marked as val@entry), or both. Note that one or both of these values may be <optimized out>. -frame-arguments all|scalars|none Set printing of non-scalar frame arguments -raw-frame-arguments [on|off] Set whether to print frame arguments in raw form. If set, frame arguments are printed in raw form, bypassing any pretty-printers for that value. -past-main [on|off] Set whether backtraces should continue past "main". Normally the caller of "main" is not of interest, so GDB will terminate the backtrace at "main". Set this if you need to see the rest of the stack trace. -past-entry [on|off] Set whether backtraces should continue past the entry point of a program. Normally there are no callers beyond the entry point of a program, so GDB will terminate the backtrace there. Set this if you need to see the rest of the stack trace. -full Print values of local variables. -no-filters Prohibit frame filters from executing on a backtrace. -hide Causes Python frame filter elided frames to not be printed. For backward compatibility, the following qualifiers are supported: full - same as -full option. no-filters - same as -no-filters option. hide - same as -hide. With a negative COUNT, print outermost -COUNT frames. ~~~~ Implementation wise, this: - Moves relevant options/settings globals to structures. - Tweaks a number of functions to pass down references to such structures. - Adds option_def structures describing the options/settings. - Makes backtrace_command parse the options, with gdb::option::process_options. - Tweaks "backtrace"'s help to describe the new options. - Adds testcases. Note that backtrace is a PROCESS_OPTIONS_UNKNOWN_IS_OPERAND command, because of the "-COUNT" argument. The COUNT/-COUNT argument is currently parsed as an expression. I considered whether it would be prudent here to require "--", but concluded that the risk of causing a significant breakage here is much lower compared to "print", since printing the expression is not the whole point of the "backtrace" command. Seems OK to me to require typing "backtrace -past-main -- -p" if the user truly wants to refer to the negative of a backtrace count stored in an inferior variable called "p". gdb/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * frame.c: Include "cli/cli-option.h.

2019-06-04Introduce and use make_unique_xstrdupPedro Alves1-1/+1
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.
2019-05-17Add debug redirect optionAlan Hayward2-9/+26
Currently, when logging is enabled, output will be sent to both a logfile and standard terminal output. The redirect option sends output only to the logfile. This includes all debug output. Add the option to redirect debug output seperately to normal output, using the cli command: set logging debugredirect on By setting this and enabling logging, all output and debug will be sent to the logfile. The user will still see all output but no debug output. This causes a change in behaviour for anyone currently using logging redirect, as now only output will be redirected. Users will have to issue the additional command above to also redirect debug. Expand ui-redirect.exp cover the changes. gdb/ChangeLog: * cli/cli-interp.c (struct saved_output_files): Add saved entry. (cli_interp_base::set_logging): Check debug_redirect. * cli/cli-interp.h (set_logging): Add debug_redirect parameter. * cli/cli-logging.c (debug_redirect): Add static variable.

2019-05-17Change file close behavior for tee_fileAlan Hayward1-5/+14
Instead of using two bools to decide if the files should close when tee_file is closed, make file one stay open and file two close. This simplifies the use cases for it. Inline the make_logging_output into the calling functions (the logic here looks ugly in order to simplify a later change). Expand ui-redirect.exp to cover the changes, similar to mi-logging.exp. gdb/ChangeLog: * cli/cli-interp.c (cli_interp_base::set_logging): Create tee_file directly. * cli/cli-interp.h (make_logging_output): Remove declaration. * cli/cli-logging.c (make_logging_output): Remove function. * mi/mi-interp.c (mi_interp::set_logging): Create tee_file directly. * ui-file.c (tee_file::tee_file): Remove bools.

2019-05-17MI: Add new command -completeJan Vrany3-0/+47
There is a CLI command 'complete' intended to use with emacs. Such a command would also be useful for MI frontends, when separate CLI and MI channels cannot be used. For example, on Windows (because of lack of PTYs) or when GDB is used through SSH session. This commit adds a new '-complete' MI command. gdb/Changelog: 2019-01-28 Jan Vrany <jan.vrany@fit.cvut.cz> * mi/mi-cmds.h (mi_cmd_complete): New function. * mi/mi-main.c (mi_cmd_complete): Likewise. * mi/mi-cmds.c: Define new MI command -complete. * NEWS: Mention new -complete command. gdb/doc/ChangeLog: 2019-01-28 Jan Vrany <jan.vrany@fit.cvut.cz> * gdb.texinfo (Miscellaneous GDB/MI Commands): Document new MI command -complete. gdb/testsuite/ChangeLog: 2019-01-28 Jan Vrany <jan.vrany@fit.cvut.cz> * gdb.mi/mi-complete.exp: New file. * gdb.mi/mi-complete.cc: Likewise.
2019-05-10Fix GDB build when using --disable-gdbmiSimon Marchi3-28/+4
Since commit b4be1b064860 ("Fix MI output for multi-location breakpoints") we get this error when building with --disable-gdbmi: CXXLD gdb /home/smarchi/src/binutils-gdb/gdb/breakpoint.c:6358: error: undefined reference to 'mi_multi_location_breakpoint_output_fixed(ui_out*)' This is due to breakpoint.c using a function defined in mi/mi-main.c, even though mi/mi-main.c isn't included in the build. To fix it, use the flags feature of ui_out. mi_ui_out has the new fix_multi_location_breakpoint_output flag set for versions >= 3. Also, move the global variable fix_multi_location_breakpoint_output to breakpoint.c, so it can be read there even when we build without MI. I renamed it to fix_multi_location_breakpoint_output_globally so it doesn't clash with the new enumerator. gdb/ChangeLog: * breakpoint.h (fix_multi_location_breakpoint_output_globally): New variable declaration. * breakpoint.c (fix_multi_location_breakpoint_output_globally): New variable. (print_one_breakpoint): Use ui_out::test_flags and new global variable to compute use_fixed_output. * mi/mi-main.h (mi_multi_location_breakpoint_output_fixed): Remove. * mi/mi-main.c (fix_multi_location_breakpoint_output): Remove. (mi_multi_location_breakpoint_output_fixed): Remove. (mi_cmd_fix_multi_location_breakpoint_output): Adjust to set the new variable. * mi/mi-out.c (mi_ui_out::mi_ui_out): Set fix_multi_location_breakpoint_output flag if version >= 3. * ui-out.h (enum ui_out_flag) <fix_multi_location_breakpoint_output>: New enumerator.
2019-04-25Make exception handling more efficientTom Tromey1-1/+1
This makes exception handling more efficient in a few spots, through the use of const- and rvalue-references. I wrote this patch by commenting out the gdb_exception copy constructor and then examining the resulting error messages one by one, introducing the use of std::move where appropriate. gdb/ChangeLog 2019-04-25 Tom Tromey <tromey@adacore.com> * xml-support.c (struct gdb_xml_parser) <set_error>: Take an rvalue reference.

2019-04-08Rename gdb exception typesTom Tromey4-5/+5
This renames the gdb exception types. The old types were only needed due to the macros in common-exception.h that are now gone.

2019-04-08Make exceptions use std::string and be self-managingTom Tromey3-17/+11
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. This also adds a noexcept copy constructor and operator= to gdb_exception, plus a "what" method. gdb/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * xml-support.c (gdb_xml_parser::parse): Update. * x86-linux-nat.c (x86_linux_nat_target::enable_btrace): Update. * value.c (show_convenience): Update. * unittests/cli-utils-selftests.c (test_number_or_range_parser) (test_parse_flags_qcs): Update. * thread.c (thr_try_catch_cmd): Update. * target.c (target_translate_tls_address): Update. * stack.c (print_frame_arg, read_frame_local, read_frame_arg) (info_frame_command_core, frame_apply_command_count): Update. * rust-exp.y (rust_lex_exception_test): Update. * riscv-tdep.c (riscv_print_one_register_info): Update. * remote.c (remote_target::enable_btrace): Update. * record-btrace.c (record_btrace_enable_warn): Update. * python/py-utils.c (gdbpy_convert_exception): Update. * printcmd.c (do_one_display, print_variable_and_value): Update. * mi/mi-main.c (mi_print_exception): Update. * mi/mi-interp.c (mi_cmd_interpreter_exec): Use SCOPE_EXIT. * mi/mi-cmd-stack.c (list_arg_or_local): Update. * linux-nat.c (linux_nat_target::attach): Update. * linux-fork.c (class scoped_switch_fork_info): Update. * infrun.c (displaced_step_prepare): Update. * infcall.c (call_function_by_hand_dummy): Update. * guile/scm-exception.c (gdbscm_scm_from_gdb_exception): Update. * gnu-v3-abi.c (print_one_vtable): Update. * frame.c (get_prev_frame_always): Update. * f-valprint.c (info_common_command_for_block): Update. * exec.c (try_open_exec_file): Update. * exceptions.c (print_exception, exception_print) (exception_fprintf, exception_print_same): Update. * dwarf2-frame.c (dwarf2_build_frame_info): Update. * dwarf-index-cache.c (index_cache::store) (index_cache::lookup_gdb_index): Update. * darwin-nat.c (maybe_cache_shell): Update. * cp-valprint.c (cp_print_value_fields): Update. * compile/compile-cplus-symbols.c (gcc_cplus_convert_symbol) (gcc_cplus_symbol_address): Update. * compile/compile-c-symbols.c (gcc_convert_symbol) (gcc_symbol_address, generate_c_for_for_one_variable): Update. * common/selftest.c: Update. * common/common-exceptions.h (struct gdb_exception) <message>: Now a std::string.

2019-03-19Don't show "display"s twice in MITom Tromey1-2/+7
If you run "gdb -i=mi2" and set a "display", then when "next"ing the displays will be shown twice: ~"1: x = 23\n" ~"7\t printf(\"%d\\n\", x);\n" ~"1: x = 23\n" *stopped,reason="end-stepping-range",frame={addr="0x0000000000400565",func="main",args=[],file="q.c",fullname="/tmp/q.c",line="7"},thread-id="1",stopped-threads="all",core="1" The immediate cause of this is this code in mi_on_normal_stop_1: print_stop_event (mi_uiout); console_interp = interp_lookup (current_ui, INTERP_CONSOLE); if (should_print_stop_to_console (console_interp, tp)) print_stop_event (mi->cli_uiout); ... which obviously prints the stop twice. However, I think the first call to print_stop_event is intended just to emit the MI *stopped notification, which explains why the source line does not show up two times. This patch fixes the bug by changing print_stop_event to only call do_displays for non-MI-like ui-outs. Tested on x86-64 Fedora 29. gdb/ChangeLog 2019-03-19 Tom Tromey <tromey@adacore.com> * mi/mi-interp.c (mi_on_normal_stop_1): Only show displays once. * infrun.h (print_stop_event): Add "displays" parameter. * infrun.c (print_stop_event): Add "displays" parameter. gdb/testsuite/ChangeLog 2019-03-19 Tom Tromey <tromey@adacore.com> * gdb.mi/mi2-cli-display.c: New file. * gdb.mi/mi2-cli-display.exp: New file.
2019-03-13Fix MI output for multi-location breakpointsSimon Marchi4-2/+44
New in v2: - Addressed comments about doc, updated the MI version table - New doc for the Breakpoint information format - New -fix-multi-location-breakpoint-output command, with associated doc, test and NEWS updated accordingly - Fixed the output, the locations list is now actually in the tuple representing the breakpoint. Various MI commands or events related to breakpoints output invalid MI records when printing information about a multi-location breakpoint. For example: -break-insert allo ^done,bkpt={...,addr="<MULTIPLE>",...},{number="1.1",...},{number="1.2",...} The problem is that according to the syntax [1], the top-level elements are of type "result" and should be of the form "variable=value". This patch changes the output to wrap the locations in a list: ^done,bkpt={...,addr="<MULTIPLE>",locations=[{number="1.1",...},{number="1.2",...}]} The events =breakpoint-created, =breakpoint-modified, as well as the -break-info command also suffer from this (and maybe others I didn't find). Since this is a breaking change for MI, we have to deal somehow with backwards compatibility. The approach taken by this patch is to bump the MI version, use the new syntax in MI3 while retaining the old syntax in MI2. Frontends are expected to use a precise MI version (-i=mi2), so if they do that they should be unaffected. The patch also adds the command -fix-multi-location-breakpoint-output, which front ends can use to enable this behavior with MI <= 2. [1] https://sourceware.org/gdb/onlinedocs/gdb/GDB_002fMI-Output-Syntax.html#GDB_002fMI-Output-Syntax gdb/ChangeLog: * NEWS: Mention that the new default MI version is 3.

2019-03-13Factor out mi_ui_out instantiation logicSimon Marchi4-31/+27
When re-reviewing this [1] I noticed that there were two spots encoding the logic of instantiating an mi_ui_out object based on the interpreter name ("mi", "mi1", "mi2" or "mi3"): - mi_interp::init - mi_load_progress Both encode the logic to choose what the default version is when the interpreter name is "mi". I had forgotten the one in mi_load_progress. Therefore, I propose extracting that logic to a single function. I started to add a new overload of mi_out_new, then realized the current mi_out_new wasn't very useful, being just a thing wrapper around "new mi_ui_out". So I ended up with just an mi_out_new function taking the interp name as parameter. I ran the gdb.mi tests, and verified manually the behavior (including the load command). [1] https://sourceware.org/ml/gdb-patches/2019-01/msg00427.html gdb/ChangeLog: * mi/mi-out.h (mi_out_new): Change parameter to const char *. * mi/mi-out.c (mi_out_new): Change parameter to const char *, instantiate mi_ui_out based on interpreter name. * mi/mi-interp.c (mi_interp::init): Use the new mi_out_new. * mi/mi-main.c (mi_load_progress): Likewise.

2019-02-07Normalize include guards in gdbTom Tromey9-30/+28
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. gdb/ChangeLog 2019-02-07 Tom

2019-01-01Update copyright year range in all GDB files.Joel Brobecker27-27/+27
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.

2018-12-28Add output styles to gdbTom Tromey2-5/+10
This adds some output styling to the CLI. A style is currently a foreground color, a background color, and an intensity (dim or bold). (This list could be expanded depending on terminal capabilities.) A style can be applied while printing. For ui-out, this is done by passing the style constant as an argument. For low-level cases, fprintf_styled and fputs_styled are provided. Users can control the style via a number of new set/show commands. In the interest of not typing many nearly-identical documentation strings, I automated this. On the down side, this is not very i18n-friendly. I've chose some default colors to use. I think it would be good to enable this by default, so that when users start the new gdb, they will see the new feature. Stylizing is done if TERM is set and is not "dumb". This could be improved when the TUI is available by using the curses has_colors call. That is, the lowest layer could call this without committing to using curses everywhere; see my other patch for TUI colorizing. I considered adding a new "set_style" method to ui_file. However, because the implementation had to interact with the pager code, I didn't take this approach. But, one idea might be to put the isatty check there and then have it defer to the lower layers. gdb/ChangeLog 2018-12-28 Tom Tromey <tom@tromey.com> * utils.h (set_output_style, fprintf_styled) (fputs_styled): Declare. * utils.c (applied_style, desired_style): New globals.

2018-11-22Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.Pedro Alves2-38/+27
As preparation for multi-target, this patch makes each inferior have its own thread list. This isn't absolutely necessary for multi-target, but simplifies things. It originally stemmed from the desire to eliminate the init_thread_list calls sprinkled around, plus it makes it more efficient to iterate over threads of a given inferior (no need to always iterate over threads of all inferiors). We still need to iterate over threads of all inferiors in a number of places, which means we'd need adjust the ALL_THREADS / ALL_NON_EXITED_THREADS macros. However, naively tweaking those macros to have an extra for loop, like: #define ALL_THREADS (thr, inf) \ for (inf = inferior_list; inf; inf = inf->next) \ for (thr = inf->thread_list; thr; thr = thr->next) causes problems with code that does "break" or "continue" within the ALL_THREADS loop body. Plus, we need to declare the extra "inf" local variable in order to pass it as temporary variable to ALL_THREADS (etc.) It gets even trickier when we consider extending the macros to filter out threads matching a ptid_t and a target. The macros become tricker to read/write. Been there. An alternative (which was my next attempt), is to replace the ALL_THREADS etc. iteration style with for_each_all_threads, for_each_non_exited_threads, etc. functions which would take a callback as parameter, which would usually be passed a lambda. However, I did not find that satisfactory at all, because the resulting code ends up a little less natural / more noisy to read, write and debug/step-through (due to use of lambdas), and in many places where we use "continue;" to skip to the next thread now need to use "return;". (I ran into hard to debug bugs caused by a continue/return confusion.) I.e., before: ALL_NON_EXITED_THREADS (tp) { if (tp->not_what_I_want) continue; // do something } would turn into: for_each_non_exited_thread ([&] (thread_info *tp) { if (tp->not_what_I_want) return; // do something }); Lastly, the solution I settled with was to replace the ALL_THREADS / ALL_NON_EXITED_THREADS / ALL_INFERIORS macros with (C++20-like) ranges and iterators, such that you can instead naturaly iterate over threads/inferiors using range-for, like e.g,.: // all threads, including THREAD_EXITED threads. for (thread_info *tp : all_threads ()) { .... } // all non-exited threads. for (thread_info *tp : all_non_exited_threads ()) { .... } // all non-exited threads of INF inferior. for (thread_info *tp : inf->non_exited_threads ()) { .... } The all_non_exited_threads() function takes an optional filter ptid_t as parameter, which is quite convenient when we need to iterate over threads matching that filter. See e.g., how the set_executing/set_stop_requested/finish_thread_state etc. functions in thread.c end up being simplified. Most of the patch thus is about adding the infrustructure for allowing the above. Later on when we get to actual multi-target, these functions/ranges/iterators will gain a "target_ops *" parameter so that e.g., we can iterate over all threads of a given target that match a given filter ptid_t. The only entry points users needs to be aware of are the all_threads/all_non_exited_threads etc. functions seen above. Thus, those functions are declared in gdbthread.h/inferior.h. The actual iterators/ranges are mainly "internals" and thus are put out of view in the new thread-iter.h/thread-iter.c/inferior-iter.h files. That keeps the gdbthread.h/inferior.h headers quite a bit more readable. A common/safe-iterator.h header is added which adds a template that can be used to build "safe" iterators, which are forward iterators that can be used to replace the ALL_THREADS_SAFE macro and other instances of the same idiom in future. There's a little bit of shuffling of code between gdbthread.h/thread.c/inferior.h in the patch. That is necessary in order to avoid circular dependencies between the gdbthread.h/inferior.h headers. As for the init_thread_list calls sprinkled around, they're all eliminated by this patch, and a new, central call is added to inferior_appeared. Note how also related to that, there's a call to init_wait_for_inferior in remote.c that is eliminated. init_wait_for_inferior is currently responsible for discarding skipped inline frames, which had to be moved elsewhere. Given that nowadays we always have a thread even for single-threaded processes, the natural place is to delete a frame's inline frame info when we delete the thread. I.e., from clear_thread_inferior_resources. gdb/ChangeLog: 2018-11-22 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_SFILES): Add thread-iter.c. * breakpoint.c (breakpoints_should_be_inserted_now): Replace ALL_NON_EXITED_THREADS with all_non_exited_threads.

2018-10-21Introduce gdbarch_num_cooked_regsSimon Marchi1-5/+5
The expression gdbarch_num_regs (gdbarch) + gdbarch_num_pseudo_regs (gdbarch) is used quite often to find the number of cooked registers (raw + pseudo registers). This patch introduces gdbarch_num_cooked_regs, which does the equivalent. It substantially reduces required wrapping in some places, so should improve readability. There is a for loop in m68hc11_frame_unwind_cache that had iterated until (the equivalent of) gdbarch_num_cooked_regs (gdbarch) - 1. During review, we concluded that this is most likely an off-by-one mistake, so I replaced it with gdbarch_num_cooked_regs (gdbarch). gdb/ChangeLog: * gdbarch.sh (gdbarch_num_cooked_regs): New. * gdbarch.h: Re-generate. * ax-gdb.c (gen_expr): Use gdbarch_num_cooked_regs. * dwarf2-frame.c (dwarf2_frame_cache): Likewise. * eval.c (evaluate_subexp_standard): Likewise. * findvar.c (value_of_register): Likewise.

2018-09-28gdb: Change how frames are selected for 'frame' and 'info frame'.Andrew Burgess1-1/+76
The 'frame' command, and thanks to code reuse the 'info frame' and 'select-frame' commands, currently have an overloaded mechanism for selecting a frame. These commands take one or two parameters, if it's one parameter then we first try to use the parameter as an integer to select a frame by level (or depth in the stack). If that fails then we treat the parameter as an address and try to select a stack frame by stack-address. If we still have not selected a stack frame, or we initially had two parameters, then GDB allows the user to view a stack frame that is not part of the current backtrace. Internally, a new frame is created with the given stack and pc addresses, and this is shown to the user. The result of this is that a typo by the user, entering the wrong stack frame level for example, can result in a brand new frame being viewed rather than an error. The purpose of this commit is to remove this overloading, while still offering the same functionality through some new sub-commands. By making the default behaviour of 'frame' (and friends) be to select a stack frame by level index, it is hoped that enough backwards-compatibility is maintained that users will not be overly inconvenienced. The 'frame', 'select-frame', and 'info frame' commands now all take a frame specification string as an argument, this string can be any of the following: (1) An integer. This is treated as a frame level. If a frame for that level does not exist then the user gets an error. (2) A string like 'level <LEVEL>', where <LEVEL> is a frame level as in option (1) above. (3) A string like 'address <STACK-ADDRESS>', where <STACK-ADDRESS> is a stack-frame address. If there is no frame for this address then the user gets an error. (4) A string like 'function <NAME>', where <NAME> is a function name, the inner most frame for function <NAME> is selected. If there is no frame for function <NAME> then the user gets an error. (5) A string like 'view <STACK-ADDRESS>', this views a new frame with stack address <STACK-ADDRESS>. (6) A string like 'view <STACK-ADDRESS> <PC-ADDRESS>', this views a new frame with stack address <STACK-ADDRESS> and the pc <PC-ADDRESS>. This change assumes that the most common use of the commands like 'frame' is to select a frame by frame level, it is for this reason that this is the behaviour that is kept for backwards compatibility. Any of the alternative behaviours, which are assumed to be less used, now require a change in user behaviour. The MI command '-stack-select-frame' has not been changed. This ensures that we maintain backwards compatibility for existing frontends. gdb/ChangeLog: (NEWS): Mention changes to frame related commands. * cli/cli-decode.c (add_cmd_suppress_notification): New function.

2018-06-21Use thread_info and inferior pointers more throughoutPedro Alves3-68/+64
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.

2018-06-07target_stack -> current_top_target() throughoutPedro Alves1-4/+4
The recent C++ification of target_ops replaced references to the old "current_target" squashed target throughout with references to a "target_stack" pointer. I had picked the "target_stack" name very early in the multi-target work, and managed to stick with it, even though it's a bit of a misnomer, since it isn't really a "target stack" object, but a pointer into the current top target in the stack. As I'm splitting more pieces off of the multi-target branch, I've come to think that it's better to rename it now. A following patch will introduce a new class to represent a target stack, and "target_stack" would be _its_ ideal name. (In the branch, the class is called a_target_stack to work around the clash.) Thus this commit renames target_stack to current_top_target and replaces all references throughout. Also, while at it, current_top_target is made a function instead of a pointer, to make it possible to change its internal implementation without leaking implementation details out. In a couple patches, the implementation of the function will change to refer to a target stack object, and then further down the multi-target work, it'll change again to find the right target stack for the current inferior. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_stack): Delete.

2018-05-25Add "name" method to class interpTom Tromey1-4/+4
In a review Pedro pointed out that interp::name is intended to be read-only, and so an accessor would be a better fit. This patch renames the field and adds a "name" method that is used instead. ChangeLog 2018-05-25 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_enable): Update. * mi/mi-interp.c (mi_interp::init): Update. * interps.h (class interp) <name>: New method. <m_name>: Rename from name. (~scoped_restore_interp): Update. * interps.c (interp::interp): Update. (interp_add, interp_set, interp_lookup_existing) (current_interp_named_p): Update.
2018-05-25Remove interp_nameTom Tromey1-2/+0
This removes the interp_name function. It is only used a few spots -- one of which was only calling it on "this". It's simpler to remove it; and should class interp become opaque in the future, it will be just as easy to update the two remaining spots to use an accessor. ChangeLog 2018-05-25 Tom Tromey <tom@tromey.com> * interps.c (interp_name): Remove. * mi/mi-interp.c (mi_interp::init): Update. * interps.h (interp_name): Remove. (~scoped_restore_interp): Update. * tui/tui.c (tui_enable): Update.
2018-05-25Remove interp_ui_outTom Tromey2-9/+9
The function interp_ui_out simply calls the interp_ui_out method. However, if it is passed a NULL interpreter, it first finds the current interpreter. I believe, though, that NULL is never passed here, and I think it's simpler to just remove this function and require callers to be more explicit. ChangeLog 2018-05-25 Tom Tromey <tom@tromey.com> * utils.c (fputs_maybe_filtered): Update. * linespec.c (decode_line_full): Update. * mi/mi-interp.c (mi_on_normal_stop_1, mi_tsv_modified) (mi_print_breakpoint_for_event, mi_solib_loaded) (mi_solib_unloaded, mi_command_param_changed, mi_memory_changed) (mi_user_selected_context_changed): Update. * mi/mi-main.c (mi_execute_command): Update. * cli/cli-script.c (execute_control_command): Update. * python/python.c (execute_gdb_command): Update. * solib.c (info_sharedlibrary_command): Update. * interps.c (interp_ui_out): Remove. * interps.h (interp_ui_out): Remove.
