2019-09-18Give a name to the TUI SingleKey keymapTom Tromey1-0/+4
Readline 8.0 has a feature that lets an application name a keymap. This in turn makes it simpler for users to bind keys in keymaps in their .inputrc. This patch gives a name to the TUI SingleKey keymap, so that additional bindings can be made there. For example: $if gdb set keymap SingleKey "X": "echo hello\\n\n" $endif The call to rl_initialize, in tui_initialize_readline, had to be removed so that .inputrc was not read too early. Note that Readline explicitly documents that this call is not needed. gdb/ChangeLog 2019-09-18 Tom Tromey <tom@tromey.com> * NEWS: Add entry. * tui/tui.c (tui_initialize_readline): Set name of keymap. Do not call rl_initialize. (tui_enable): Do not call rl_initialize. gdb/doc/ChangeLog 2019-09-18 Tom Tromey <tom@tromey.com> * gdb.texinfo (Editing): Document readline application name. (TUI Single Key Mode): Document TUI SingleKey keymap name.

2019-09-12Output the Ada task name in more messages.Philippe Waroquiers1-0/+3
With this patch, we e.g. get: [Switching to task 2 "task_list(1)"] [Current task is 2 "task_list(1)"] instead of [Switching to task 2] [Current task is 2] The logic to produce the taskno optionally followed by the task name has been factorized in the task_to_str function. Task names are output between double quotes in the new messages, similarly to what GDB does for thread names. However, no quotes are put around task names in 'info tasks' Name column. This was discussed with Tom, that preferred no quotes there, while I was more in favour of visual consistency. I discussed with a few more users, which led to (exactly) 50% preferring quotes and 50% preferring no quotes :). To arrive to the decision to remove the quotes, the following "killing args" were used: * To have quotes or to not have quotes, that is the question; yes but not *THE* question :). * If there is not a clear majority that prefers quotes, better to not disturb the existing user basis for a (somewhat) irrelevant aspect. * The opinion of the reviewer has more weight. So, compared to the previous version, this version remotes the quotes in 'info tasks'. It improves the alignement of 'info tasks' output. With this patch, we get: (gdb) info task ID TID P-ID Pri State Name * 1 555555759030 48 Runnable main_task 2 555555759e30 1 48 Selective Wait mit (gdb) instead of (gdb) info task ID TID P-ID Pri State Name * 1 555555759030 48 Runnable main_task 2 555555759e30 1 48 Selective Wait mit (gdb) (e.g. the first one properly shows parent and priority under the correct header). This is version 4 of the 'task name' patch. Compared to version 3, the changes are: output task names between quotes but not in 'info tasks' gdb/ChangeLog 2019-09-12 Philippe Waroquiers <philippe.waroquiers@skynet.be> * NEWS: Announce that Ada task names are now shown at more places, and between quotes (except in info task output). * gdb/ada-tasks.c (task_to_str): New function.

2019-08-27gdb: Add new -n flag to some info commandsAndrew Burgess1-0/+5
The 'info variables', its alias 'whereis', and 'info functions' all include non-debug symbols in the output by default. The list of non-debug symbols can sometimes be quite long, resulting in the debug symbol based results being scrolled off the screen.

2019-08-07AArch64 pauth: Indicate unmasked addresses in backtraceAlan Hayward1-1/+3
Armv8.3-a Pointer Authentication causes the function return address to be obfuscated on entry to some functions. GDB must unmask the link register in order to produce a backtrace. The following patch adds markers of [PAC] to the bracktrace, to indicate which addresses needed unmasking. This includes the backtrace when using MI. For example, consider the following backtrace: (gdb) bt 0 0x0000000000400490 in puts@plt () 1 0x00000000004005dc in foo ("hello") at cbreak-lib.c:6 2 0x0000000000400604 [PAC] in bar () at cbreak-lib.c:12 3 0x0000000000400620 [PAC] in main2 () at cbreak.c:17 4 0x00000000004005b4 in main () at cbreak-3.c:10 The functions in cbreak-lib use pointer auth, which masks the return address to the previous function, causing the addresses of bar (in the library) and main2 (in the main binary) to require unmasking in order to unwind the backtrace. An extra bool is added alongside the prev_pc in the frame structure. At the point at which the link register is unmasked, the AArch64 port calls into frame to sets the bool. This is the most efficient way of doing it. The marker is also added to the python frame printer, which is always printed if set. The marker is not explicitly exposed to the python code. I expect this will potentially cause issues with some tests in the testsuite when Armv8.3 pointer authentication is used. This should be fixed up in the the future once real hardware is available for full testsuite testing. gdb/ChangeLog: * NEWS: Expand the Pointer Authentication entry. * aarch64-tdep.c (aarch64_frame_unmask_address): Rename from this. (aarch64_frame_unmask_lr): ... to this. (aarch64_prologue_prev_register, aarch64_dwarf2_prev_register): Call aarch64_frame_unmask_lr. * frame.c (struct frame_info): Add "masked" variable.

2019-08-01Require GNU make 3.82Alan Hayward1-0/+5
Gdbserver has failed to build with GNU make 3.81 since commit 08f10e02be. Update the NEWS file to state that versions earlier than 3.82 are not supported. 3.82 was released in 2010, 3.81 was released 2006. A quick investigation of the default GNU make version provided across various distros found the earliest provided version to be 3.82: *RHEL 7, Centos 6 - make 3.82 *Fedora 27 - make 4.2.1 *OpenSuse 42.2, SLES11 - make 4.2.1 *Ubuntu 16.04/18.04 - make 4.1 *Debian Jessie - make 4.0 Note that Glibc requires at least 4.0, whereas GCC still allows 3.81. gdb/ChangeLog: * NEWS: Require GNU make 3.82.

2019-07-08Ensure GDB printf command can print convenience var strings without a target.Philippe Waroquiers1-0/+7
Without this patch, GDB printf command calls malloc on the target, writes the convenience var content to the target, re-reads the content from the target, and then locally printf the string. This implies inferior calls, and does not work when there is no running inferior, or when the inferior is a core dump. With this patch, printf command can printf string convenience variables without inferior function calls. Ada string convenience variables can also be printed. gdb/ChangeLog 2019-07-08 Philippe Waroquiers <philippe.waroquiers@skynet.be> * NEWS: Mention that GDB printf and eval commands can now print C-style and Ada-style convenience var strings without calling the inferior. * printcmd.c (printf_c_string): Locally print GDB internal var instead of transiting via the inferior.

2019-07-03Introduce the "with" commandPedro Alves1-0/+15
( See original discussion and prototype here: https://sourceware.org/ml/gdb-patches/2019-05/msg00570.html ) (gdb) help with Temporarily set SETTING to VALUE, run COMMAND, and restore SETTING. Usage: with SETTING [VALUE] [-- COMMAND] Usage: w SETTING [VALUE] [-- COMMAND] With no COMMAND, repeats the last executed command. SETTING is any setting you can change with the "set" subcommands. E.g.: with language pascal -- print obj with print elements unlimited -- print obj As can be seen above, the "with" command is just like "set", but instead of setting the setting permanently, it sets the setting, runs a command and then restores the setting. (gdb) p g_s $1 = {a = 1, b = 2, c = 3} (gdb) with language ada -- print g_s $2 = (a => 1, b => 2, c => 3) Warning: the current language does not match this frame. (gdb) show language The current source language is "auto; currently c". (gdb) with print elements 100 -- with print object on -- print 1 $3 = 1 You can shorten things a bit though, as long as unambiguous. So this: (gdb) with print elements 100 -- with print object off -- print 1 is the same as: (gdb) w p el 100 -- w p o 0 -- p 1 Note that the patch adds a "w" alias for "with", as "w" is not currently taken: (gdb) w Ambiguous command "w": watch, wh, whatis, where, while, while-stepping, winheight, ws. Let me know if you'd prefer to reserve "w" for one of the other commands above. IMHO, this command will end up being used frequently enough that it deserves the "w" shorthand. A nice feature is that this is fully integrated with TAB-completion: (gdb) with p[TAB] pagination print prompt python (gdb) with print [TAB] address max-depth static-members array max-symbolic-offset symbol array-indexes null-stop symbol-filename asm-demangle object symbol-loading demangle pascal_static-members thread-events elements pretty type entry-values raw union frame-arguments repeats vtbl inferior-events sevenbit-strings (gdb) with print [TAB] (gdb) with print elements unlimited -- thread apply all -[TAB] -ascending -c -q -s (gdb) with print elements unlimited -- print -[TAB] -address -max-depth -repeats -vtbl -array -null-stop -static-members -array-indexes -object -symbol -elements -pretty -union The main advantage of this new command compared to command options, like the new "print -OPT", is that this command works with any setting, and, it works nicely when you want to override a setting while running a user-defined command, like: (gdb) with print pretty -- usercmd The disadvantage is that it isn't as compact or easy to type. I think of command options and this command as complementary. I think that even with this new command, it makes sense to continue developing the command options in the direction of exposing most-oft-used settings as command options. Inspired by Philippe's "/" command proposal, if no command is specified, then the last command is re-invoked, under the overridden setting: (gdb) p g_s $1 = {a = 1, b = 2, c = 3} (gdb) with language ada $2 = (a => 1, b => 2, c => 3) Warning: the current language does not match this frame. Note: "with" requires "--" to separate the setting from the command. It might be possible to do without that, but, I haven't tried it yet, and I think that this can go in without it. We can always downgrade to making "--" optional if we manage to make it work. On to the patch itself, the implementation of the command is simpler than one might expect. A few details: - I factored out a bit from pipe_command into repeat_previous directly, because otherwise I'd need to copy&paste the same code and same error message in the with command. - The parse_cli_var_uinteger / parse_cli_var_zuinteger_unlimited / do_set_command changes are necessary since we can now pass an empty string as argument. - do_show_command was split in two, as a FIXME comment suggests, but for a different reason: we need to get a string version of a "set" command's value, and we already had code for that in do_show_command. That code is now factored out to the new get_setshow_command_value_string function. - There's a new "maint with" command added too: (gdb) help maint with Like "with", but works with "maintenance set" variables. Usage: maintenance with SETTING [VALUE] [-- COMMAND] With no COMMAND, repeats the last executed command. SETTING is any setting you can change with the "maintenance set" subcommands. "with" and "maint with" share 99% of the implementation. This might be useful on its own, but it's also useful for testing, since with this, we can use the "maint set/show test-settings" settings for exercising the "with" machinery with all the command type variants (all enum var_types). This is done in the new gdb/base/with.exp testcase. The documentation bits are originally based on Philippe's docs for the "/" command, hence the attribution in the ChangeLog. gdb/ChangeLog: 2019-07-03 Pedro Alves <palves@redhat.com> * NEWS (New commands): Mention "with" and "maint with". * cli/cli-cmds.c (with_command_1, with_command_completer_1) (with_command, with_command_completer): New.

This makes "info threads" use the gdb::option framework to process options. There's only one option today (-gid), and it isn't used much frequently unless you're looking at matching MI output. Still, this was in the neighborhood of "thread apply" so I had converted it. The main advantage is that TAB completion now shows you the available options, and gives you a hint to what the command accepts as operand argument, including showing a metasyntactic variable: (gdb) info threads [TAB] -gid ID (gdb) help info threads Display currently known threads. Usage: info threads [OPTION]... [ID]... Options: -gid Show global thread IDs. If ID is given, it is a space-separated list of IDs of threads to display. Otherwise, all threads are displayed.

2019-06-15gdb/mi: New commands to catch C++ exceptionsAndrew Burgess1-0/+4
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.

2019-06-13"set print raw frame-arguments" -> "set print raw-frame-arguments"Pedro Alves1-0/+7
A following patch will introduce options for the "backtrace" command, based on some "set print" and "set backtrace" settings. There's one setting in particular that is a bit annoying if we want to describe the backtrace options and the settings commands using the same data structures: "set print raw frame-arguments" The problem is that space between "raw" and "frame-arguments". Calling the option "bt -raw frame-arguments" would be odd. So I'm calling the option "bt -raw-frame-arguments" instead. And for consistency, this patch renames the set/show commands to: "set print raw-frame-arguments" "show print raw-frame-arguments" I.e., dash instead of space. The old commands are left in place, but marked deprecated. We need to adjust a couple testcases, because the relevant tests use gdb_test_no_output and the old commands are no longer silent: (gdb) set print raw frame-arguments on Warning: command 'set print raw frame-arguments' is deprecated. Use 'set print raw-frame-arguments'. gdb/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * NEWS (Changed commands): Mention set/show print raw-frame-arguments, and that "set/show print raw frame-arguments" are now deprecated. * cli/cli-decode.c (add_setshow_boolean_cmd): Now returns the command. * command.h (add_setshow_boolean_cmd): Return cmd_list_element *. * stack.c (_initialize_stack): Install "set/show print raw-frame-arguments", and deprecate "set/show print raw frame-arguments". * valprint.c (_initialize_valprint): Deprecate "set/show print raw". gdb/doc/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * gdb.texinfo (Print Settings): Document "set/show print raw-frame-arguments" instead of "set/show print raw frame-arguments". gdb/testsuite/ChangeLog: 2019-06-13 Pedro Alves <palves@redhat.com> * gdb.guile/scm-frame-args.exp: Use "set print raw-frame-arguments" instead of "set print raw frame-arguments". * gdb.python/py-frame-args.exp: Likewise.

2019-04-29gdb: Introduce 'print max-depth' featureAndrew Burgess1-0/+9
Introduce a new print setting max-depth which can be set with 'set print max-depth DEPTH'. The default value of DEPTH is 20, but this can also be set to unlimited. When GDB is printing a value containing nested structures GDB will stop descending at depth DEPTH. Here is a small example: typedef struct s1 { int a; } s1; typedef struct s2 { s1 b; } s2; typedef struct s3 { s2 c; } s3; typedef struct s4 { s3 d; } s4; s4 var = { { { { 3 } } } }; The following table shows how various depth settings affect printing of 'var': | Depth Setting | Result of 'p var' | |---------------+--------------------------------| | Unlimited | $1 = {d = {c = {b = {a = 3}}}} | | 4 | $1 = {d = {c = {b = {a = 3}}}} | | 3 | $1 = {d = {c = {b = {...}}}} | | 2 | $1 = {d = {c = {...}}} | | 1 | $1 = {d = {...}} | | 0 | $1 = {...} | Only structures, unions, and arrays are replaced in this way, scalars and strings are not replaced. The replacement is counted from the level at which you print, not from the top level of the structure. So, consider the above example and this GDB session: (gdb) set print max-depth 2 (gdb) p var $1 = {d = {c = {...}}} (gdb) p var.d $2 = {c = {b = {...}}} (gdb) p var.d.c $3 = {b = {a = 3}} Setting the max-depth to 2 doesn't prevent the user from exploring deeper into 'var' by asking for specific sub-fields to be printed. The motivation behind this feature is to try and give the user more control over how much is printed when examining large, complex data structures. The default max-depth of 20 means that there is a change in GDB's default behaviour. Someone printing a data structure with 20 levels of nesting will now see '{...}' instead of their data, they would need to adjust the max depth, or call print again naming a specific field in order to dig deeper into their data structure. If this is considered a problem then we could increase the default, or even make the default unlimited. This commit relies on the previous commit, which added a new field to the language structure, this new field was a string that contained the pattern that should be used when a structure/union/array is replaced in the output, this allows languages to use a syntax that is more appropriate, mostly this will be selecting the correct types of bracket '(...)' or '{...}', both of which are currently in use. This commit should have no impact on MI output, expressions are printed through the MI using -var-create and then -var-list-children. As each use of -var-list-children only ever displays a single level of an expression then the max-depth setting will have no impact. This commit also adds the max-depth mechanism to the scripting language pretty printers following basically the same rules as for the built in value printing. One quirk is that when printing a value using the display hint 'map', if the keys of the map are structs then GDB will hide the keys one depth level after it hides the values, this ensures that GDB produces output like this: $1 = map_object = {[{key1}] = {...}, [{key2}] = {...}} Instead of this less helpful output: $1 = map_object = {[{...}] = {...}, [{...}] = {...}} This is covered by the new tests in gdb.python/py-nested-maps.exp. gdb/ChangeLog: * cp-valprint.c (cp_print_value_fields): Allow an additional level of depth when printing anonymous structs or unions. * guile/scm-pretty-print.c (gdbscm_apply_val_pretty_printer): Don't print either the top-level value, or the children if the max-depth is exceeded.

2019-04-27Implement show | set may-call-functions [on|off]Philippe Waroquiers1-0/+12
Inferior function calls are powerful but might lead to undesired results such as crashes when calling nested functions (frequently used in particular in Ada). This implements a GDB setting to disable calling inferior functions. Note: the idea is that if/when the 'slash command' patch is pushed, that this setting can be changed e.g. by using the shortcut /c. This is version 2 of the patch. It handles all the received comments, mostly replace 'can-call' by 'may-call', and avoid using 'inferior function call' in factor of 'calling function in the program'. 2019-04-26 Philippe Waroquiers <philippe.waroquiers@skynet.be> gdb/ChangeLog * NEWS: Mention the new set|show may-call-functions. * infcall.c (may_call_functions_p): New variable.

2019-04-01gdb: Add $_cimag and $_creal internal functionsAndrew Burgess1-1/+3
Add two new internal functions $_cimag and $_creal that extract the imaginary and real parts of a complex value. These internal functions can take a complex value of any type 'float complex', 'double complex', or 'long double complex' and return a suitable floating point value 'float', 'double', or 'long double'. So we can now do this: (gdb) p z1 $1 = 1.5 + 4.5 * I (gdb) p $_cimag (z1) $4 = 4.5 (gdb) p $_creal (z1) $4 = 1.5 The components of a complex value are not strictly named types in DWARF, as the complex type is itself the base type. However, once we are able to extract the components it makes sense to be able to ask what the type of these components is and get a sensible answer back, rather than the error we would currently get. Currently GDB says: (gdb) ptype z1 type = complex double (gdb) p $_cimag (z1) $4 = 4.5 (gdb) ptype $ type = <invalid type code 9> With the changes in dwarf2read.c, GDB now says: (gdb) ptype z1 type = complex double (gdb) p $_cimag (z1) $4 = 4.5 (gdb) ptype $ type = double Which seems to make more sense. gdb/ChangeLog: * NEWS: Mention new internal functions. * dwarf2read.c (dwarf2_init_complex_target_type): New function.

2019-03-13Fix MI output for multi-location breakpointsSimon Marchi1-0/+14
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.
