2017-09-27Constify some commands in exec.c, plus symbol_file_commandTom Tromey1-1/+1
Note that this commit also changes deprecated_file_changed_hook -- not used in the tree, but Insight will require a (presumably minor) change. gdb/ChangeLog 2017-09-27 Tom Tromey <tom@tromey.com> * symfile.c (symbol_file_command): Constify. * gdbcore.h (deprecated_file_changed_hook): Constify. * exec.c (deprecated_file_changed_hook, exec_file_command) (file_command): Constify. * defs.h (symbol_file_command): Constify.
2017-09-23Removed unused declarationTom Tromey1-6/+0
An earlier patch of mine removed make_cleanup_override_quit_handler, but neglected to remove the declaration. This patch removes it. Tested by rebuilding. I'm committing this as obvious. ChangeLog 2017-09-23 Tom Tromey <tom@tromey.com> * defs.h (make_cleanup_override_quit_handler): Don't declare.
2017-09-04Move command lines types/declarations to cli-script.hSimon Marchi1-74/+0
I think it would make more sense if the types and function declarations related to command lines were in cli-script.h rather than defs.h, since the related function definitions are in cli-script.c. I had to add a few includes here and there. I also had to rename the "lines" parameter of command_lines_deleter::operator(), because ncurses has a "#define lines ..." that was interfering when cli-script.h is included by some TUI source files that also include ncurses header files. gdb/ChangeLog: * cli/cli-script.h (enum misc_command_type): Move from defs.h.

2017-07-20Make language_def O(1)Pedro Alves1-1/+2
Profiling GDB with the rest of series applied, I saw calls to language_def showing up high in some runs. The problem is that language_def is O(N) currently, since walk the languages vector each time to find the matching language_defn. IMO, the add_language mechanism is pointless, because "enum language" implies the core of GDB needs to know about all languages anyway. So simply make the languages vector array be an array where each element's index is the corresponding enum language enumerator. Note that "local_language_defn" is gone along the way. It's just a copy of "auto", so the new code simply maps one to the other. One fewer place to update when we need to change the language vector... Also, a while ago the output of "set language" was made out of order as side effect of some other change. While I was at it, I made them sorted again. gdb/ChangeLog: 2017-07-20 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_language_defn): Make extern.

2017-06-16extract/store integer function templateYao Qi1-8/+39
This patch converts functions extract_{unsigned,signed}_integer to a function template extract_integer, which has two instantiations. It also does the similar changes to store__{unsigned,signed}_integer, regcache::raw_read_{unsigned,signed}, regcache::raw_write_{unsigned,signed}, regcache::cooked_read_{unsigned,signed}, regcache::cooked_write_{unsigned,signed}. This patch was posted here https://sourceware.org/ml/gdb-patches/2017-05/msg00492.html but the problem was fixed in a different way. However, I think the patch is still useful to shorten the code. gdb: 2017-06-16 Alan Hayward <alan.hayward@arm.com> Pedro Alves <palves@redhat.com> Yao Qi <yao.qi@linaro.org> * defs.h (RequireLongest): New.

2017-04-12Introduce command_line_upTom Tromey1-7/+21
This introduces command_line_up, a unique_ptr for command_line objects, and changes many places to use it. This removes a number of cleanups. Command lines are funny in that sometimes they are reference counted. Once there is more C++-ification of some of the users, perhaps all of these can be changed to use shared_ptr instead. gdb/ChangeLog 2017-04-12 Tom Tromey <tom@tromey.com> * tracepoint.c (actions_command): Update. * python/python.c (python_command, python_interactive_command): Update. * mi/mi-cmd-break.c (mi_cmd_break_commands): Update. * guile/guile.c (guile_command): Update. * defs.h (read_command_lines, read_command_lines_1): Return command_line_up.

2016-11-23gdb: Use C++11 std::chronoPedro Alves1-14/+0
This patch fixes a few problems with GDB's time handling. #1 - It avoids problems with gnulib's C++ namespace support On MinGW, the struct timeval that should be passed to gnulib's gettimeofday replacement is incompatible with libiberty's timeval_sub/timeval_add. That's because gnulib also replaces "struct timeval" with its own definition, while libiberty expects the system's. E.g., in code like this: gettimeofday (&prompt_ended, NULL); timeval_sub (&prompt_delta, &prompt_ended, &prompt_started); timeval_add (&prompt_for_continue_wait_time, &prompt_for_continue_wait_time, &prompt_delta); That's currently handled in gdb by not using gnulib's gettimeofday at all (see common/gdb_sys_time.h), but that #undef hack won't work with if/when we enable gnulib's C++ namespace support, because that mode adds compile time warnings for uses of ::gettimeofday, which are hard errors with -Werror. #2 - But there's an elephant in the room: gettimeofday is not monotonic... We're using it to: a) check how long functions take, for performance analysis b) compute when in the future to fire events in the event-loop c) print debug timestamps But that's exactly what gettimeofday is NOT meant for. Straight from the man page: ~~~ The time returned by gettimeofday() is affected by discontinuous jumps in the system time (e.g., if the system administrator manually changes the system time). If you need a monotonically increasing clock, see clock_gettime(2). ~~~ std::chrono (part of the C++11 standard library) has a monotonic clock exactly for such purposes (std::chrono::steady_clock). This commit switches to use that instead of gettimeofday, fixing all the issues mentioned above. gdb/ChangeLog: 2016-11-23 Pedro Alves <palves@redhat.com> * Makefile.in (SFILES): Add common/run-time-clock.c.

2016-10-25Fix gdb C++ compilation on Solaris (PR build/20712)Rainer Orth1-10/+0
gdb 7.12 doesn't compile as C++ (tried with g++ 4.9) on Solaris (tried 10 and 12, sparc and x86). The following patch (relative to the 7.12 release, though I expect most if not all issues to be present on trunk, too) fixes this. Only a few of the changes bear explanation: * Initially, compilation failed whereever defs.h. was included: In file included from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19:0: /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:630:33: error: 'double atof(const char*)' conflicts with a previous declaration extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ ^ In file included from /usr/include/stdlib.h:17:0, from build-gnulib/import/stdlib.h:36, from /vol/src/gnu/gdb/gdb-7.12/gdb/common/common-defs.h:32, from /vol/src/gnu/gdb/gdb-7.12/gdb/defs.h:28, from /vol/src/gnu/gdb/gdb-7.12/gdb/gdb.c:19: /vol/gcc-4.9/lib/gcc/i386-pc-solaris2.10/4.9.0/include-fixed/iso/stdlib_iso.h:119:15: note: previous declaration 'double std::atof(const char*)' extern double atof(const char *); ^ This is due to this gem in gdb/defs.h which seems to have been present like forever: #ifndef atof extern double atof (const char *); /* X3.159-1989 4.10.1.1 */ #endif In the Solaris headers, the appropriate functions are in namespace std, thus the conflict. I've wrapped the defs.h declaration in !__cplusplus to avoid this; perhaps it can go completely instead. * All the casts are necessary to appease g++ and should be pretty obvious. * The sol-thread.c changes are here to handle /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c: In function 'void _initialize_sol_thread()': /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1252:36: error: invalid conversion from 'void*' to 'void (*)(int)' [-fpermissive] if (!(p_##X = dlsym (dlhandle, #X))) \ ^ /vol/src/gnu/gdb/gdb-7.12/gdb/sol-thread.c:1255:3: note: in expansion of macro 'resolve' resolve (td_log); ^ and are modeled after linux-thread-db.c (try_thread_db_load_1). The patch allowed both 32 and 64-bit C++ builds on sparc-sun-solaris2.10 and i386-pc-solaris2.10 to complete. The resulting binary hasn't seen more than a smoke test (invoke it on itself, b main, run) yet.

2016-10-03Emit inferior, thread and frame selection events to all UIsAntoine Tremblay1-0/+16
With this patch, when an inferior, thread or frame is explicitly selected by the user, notifications will appear on all CLI and MI UIs. When a GDB console is integrated in a front-end, this allows the front-end to follow a selection made by the user ont he CLI, and it informs the user about selection changes made behind the scenes by the front-end. This patch addresses PR gdb/20487. In order to communicate frame changes to the front-end, this patch adds a new field to the =thread-selected event for the selected frame. The idea is that since inferior/thread/frame can be seen as a composition, it makes sense to send them together in the same event. The vision would be to eventually send the inferior information as well, if we find that it's needed, although the "=thread-selected" event would be ill-named for that job. Front-ends need to handle this new field if they want to follow the frame selection changes that originate from the console. The format of the frame attribute is the same as what is found in the *stopped events. Here's a detailed example for each command and the events they generate: thread ------ 1. CLI command: thread 1.3 MI event: =thread-selected,id="3",frame={...} 2. MI command: -thread-select 3 CLI event: [Switching to thread 1.3 ...] 3. MI command (CLI-in-MI): thread 1.3 MI event/reply: &"thread 1.3\n" ~"#0 child_sub_function () ... =thread-selected,id="3",frame={level="0",...} ^done frame ----- 1. CLI command: frame 1 MI event: =thread-selected,id="3",frame={level="1",...} 2. MI command: -stack-select-frame 1 CLI event: #1 0x00000000004007f0 in child_function... 3. MI command (CLI-in-MI): frame 1 MI event/reply: &"frame 1\n" ~"#1 0x00000000004007f9 in ..." =thread-selected,id="3",frame={level="1"...} ^done inferior -------- Inferior selection events only go from the console to MI, since there's no way to select the inferior in pure MI. 1. CLI command: inferior 2 MI event: =thread-selected,id="3" Note that if the user selects an inferior that is not started or exited, the MI doesn't receive a notification. Since there is no threads to select, the =thread-selected event does not apply... 2. MI command (CLI-in-MI): inferior 2 MI event/reply: &"inferior 2\n" ~"[Switching to inferior 2 ...]" =thread-selected,id="4",frame={level="0"...} ^done Internal implementation detail: this patch makes it possible to suppress notifications caused by a CLI command, like what is done in mi-interp.c. This means that it's now possible to use the add_com_suppress_notification function to register a command with some event suppressed. It is used to implement the select-frame command in this patch. The function command_notifies_uscc_observer was added to extract the rather complicated logical expression from the if statement. It is also now clearer what that logic does: if the command used by the user already notifies the user_selected_context_changed observer, there is not need to notify it again. It therefore protects again emitting the event twice.

PR python/20190 arose from an exception I noticed when trying to use the Python unwinder for Spider Monkey in Firefox. The problem is that the unwinder wants to examine the value of a thread-local variable. However, sympy_value rejects this because symbol_read_needs_frame returns true for a TLS variable. This problem arose once before, though in a different context: https://sourceware.org/bugzilla/show_bug.cgi?id=11803 At the time Pedro and Daniel pointed out a simpler way to fix that bug (see links in 20190 if you are interested); but for this new bug I couldn't think of a similar fix and ended up implementing Daniel's other suggestion: https://sourceware.org/ml/gdb-patches/2010-07/msg00393.html That is, this patch makes it possible to detect whether a symbol needs a specific frame, or whether it just needs the inferior to have registers.

2016-06-23Move logic out of symbol_find_demangled_nameTom Tromey1-4/+14
This patch moves most of the demangling logic out of symbol_find_demangled_name into the various language_defn objects. The simplest way to do this seemed to be to add a new method to language_defn. This is shame given the existing la_demangle, but given Ada's unusual needs, and the differing demangling options between languages, la_demangle didn't seem to fit. In order to make this work, I made enum language order-sensitive.

2016-06-21Make stdin be per UIPedro Alves1-1/+3
This commit makes each UI have its own "stdin" stream pointer. This is used to determine whether the "from_tty" argument to execute_command, etc. should be true. Related, this commit makes input_from_terminal_p take an UI parameter, and then avoids the gdb_has_a_terminal in it. gdb_has_a_terminal only returns info on gdb's own main/primary terminal (the real stdin). However, the places that call input_from_terminal_p really want to know is whether the command came from an interactive tty. This patch thus renames input_from_terminal_p to input_interactive_p for clarity, and then makes input_interactive_p check for "set interactive" itself, along with ISATTY, instead of calling gdb_has_a_terminal. Actually, quit_force wants to call input_interactive_p _after_ stdin is closed, we can't call ISATTY that late. So instead we save the result of ISATTY in a field of the UI. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-script.c (read_next_line): Adjust to per-UI stdin.

2016-04-12target remote: Don't rely on immediate_quit (introduce quit handlers)Pedro Alves1-4/+30
remote.c is the last user of immediate_quit. It's relied on to immediately break the initial remote connection sync up, if the user does Ctrl-C, assuming that was because the target isn't responding. At that stage, since the connection isn't synced yet, disconnecting is the only safe thing to do. This commit reworks that, to not rely on throwing from the SIGINT signal handler. So, this commit: - Introduces the concept of a "quit handler". This is used to override what does the QUIT macro do when the quit flag is set. - Makes the "struct serial" reachar / write code call QUIT in the partial read/write loops, so the current quit handler is invoked whenever a serial->read_prim / serial->write_prim returns EINTR. - Makes the "struct serial" reachar / write code call interruptible_select instead of gdb_select, so that QUITs are detected in a race-free manner. - Stops remote.c from setting immediate_quit during the initial connection. - Instead, we install a custom quit handler whenever we're calling into the serial code. This custom quit handler knows to immediately throw a quit when we're in the initial connection setup, and otherwise defer handling the quit/Ctrl-C request to later, when we're safely out of a packet command/response sequence. This also is what is now responsible for handling "double Ctrl-C because target connection is stuck/wedged." - remote.c no longer installs a specialized SIGINT handlers, and instead re-uses the quit flag. Since we want to rely on the QUIT macro, the SIGINT handler must also set the quit. And the easiest is just to not install custom SIGINT handler in remote.c. Let the standard SIGINT handler do its job of setting the quit flag. Centralizing SIGINT handlers seems like a good thing to me, anyway. gdb/ChangeLog: 2016-04-12 Pedro Alves <palves@redhat.com> * defs.h (quit_handler_ftype, quit_handler) (make_cleanup_override_quit_handler, default_quit_handler): New.

2016-04-12Introduce interruptible_selectPedro Alves1-0/+11
We have places where we call a blocking gdb_select expecting that a Ctrl-C will unblock it. However, if the Ctrl-C is pressed just before gdb_select, the SIGINT handler runs before gdb_select, and thus gdb_select won't return. For example gdb_readline_no_editing: QUIT; /* Wait until at least one byte of data is available. Control-C can interrupt gdb_select, but not fgetc. */ FD_ZERO (&readfds); FD_SET (fd, &readfds); if (gdb_select (fd + 1, &readfds, NULL, NULL, NULL) == -1) and stdio_file_read: /* For the benefit of Windows, call gdb_select before reading from the file. Wait until at least one byte of data is available. Control-C can interrupt gdb_select, but not read. */ { fd_set readfds; FD_ZERO (&readfds); FD_SET (stdio->fd, &readfds); if (gdb_select (stdio->fd + 1, &readfds, NULL, NULL, NULL) == -1) return -1; } return read (stdio->fd, buf, length_buf); This is a race classically fixed with either the self-pipe trick, or by blocking SIGINT and then using pselect instead of select. Blocking SIGINT most of the time would mean that check_quit_flag (and thus QUIT) would need to do a syscall every time it is called, which sounds best avoided, since QUIT is called in many loops. Thus we take the self-pipe trick route (wrapped in a serial event). Instead of having all places that need this manually add an extra file descriptor to the set of gdb_select's watched file descriptors, we introduce a wrapper, interruptible_select, that does that. The Windows version of gdb_select actually does not suffer from this, because mingw-hdep.c:gdb_call_async_signal_handler sets a Windows event that gdb_select always waits on. So this patch can be seen as generalization of that technique. We can't remove that extra event from mingw-hdep.c until we get rid of immediate_quit though. gdb/ChangeLog: 2016-04-12 Pedro Alves <palves@redhat.com> * defs.h: Extend QUIT-related comments to mention interruptible_select.

2015-08-25remote: allow aborting long operations (e.g., file transfers)Pedro Alves1-11/+9
Currently, when remote debugging, if you type Ctrl-C just while the target stopped for an internal event, and GDB is busy doing something that takes a while (e.g., fetching chunks of a shared library off of the target, with vFile, to process ELF headers and debug info), the Ctrl-C is lost. The patch hooks up the QUIT macro to a new target method that lets the target react to the double-Ctrl-C before the event loop is reached, which allows reacting to a double-Ctrl-C even when GDB is busy doing some long operation and not waiting for a stop reply. That end result is: (gdb) c Continuing. ^C ^C Interrupted while waiting for the program. Give up waiting? (y or n) y Quit (gdb) info threads Id Target Id Frame * 1 Thread 11673 0x00007ffff7deb240 in _dl_debug_state () from target:/lib64/ld-linux-x86-64.so.2 (gdb) If, however, GDB is waiting for a stop reply (because the target has been resumed, with e.g., vCont;c), but the target isn't responding, we now get: (gdb) c Continuing. ^C ^C The target is not responding to interrupt requests. Stop debugging it? (y or n) y Disconnected from target. (gdb) info threads No threads. This offers to disconnect, because when we're waiting for a stop reply, there's nothing else we can send the target other than an interrupt request. And if that doesn't work, there's nothing else we can do. The Ctrl-C is presently lost because until we get to a user-visible stop, the SIGINT handler that is installed is the one that forwards the interrupt to the remote side, with the \003 "packet" [1]. But, gdbserver ignores an interrupt request if the program is stopped. Still, even if it didn't, the server can only report back a stop-because-of-SIGINT when the program is next resumed. And it may take a while to actually re-resume the target. [1] - In the old sync days, the remote target would react to a double-Ctrl-C by asking users whether they wanted to give up waiting and disconnect. The code is still there, but it it isn't reacheable on most hosts, which support serial connections in async mode (probably only DJGPP doesn't). Even then, in sync mode, remote.c's SIGINT handler is only installed while the target is resumed, and is removed as soon as the target sends back a stop reply. That means that a Ctrl-C just while GDB is processing an internal event can end up with an odd "Quit" at the prompt instead of "Program stopped by SIGINT". In contrast, in async mode, remote.c's SIGINT handler is set up as long as target_terminal_inferior or target_terminal_ours_for_output are in effect (IOW, until we get a user-visible stop and call target_terminal_ours), so the user shouldn't get back a spurious Quit. However, it's still desirable to be able to interrupt a long-running GDB operation, if GDB takes a while to re-resume the target or get back to the event loop.

2015-05-16compile: New 'compile print'Jan Kratochvil1-0/+9
It is planned the existing GDB command 'print' will be able to evaluate its expressions using the compiler. There will be some option to choose between the existing GDB evaluation and the compiler evaluation. But as an intermediate step this patch provides the expression printing feature as a new command. I can imagine it could be also called 'maintenance compile print' as in the future one should be able to use its functionality by the normal 'print' command. There was a discussion with Eli about the command name: https://sourceware.org/ml/gdb-patches/2015-03/msg00880.html As there were no other comments yet I haven't renamed it yet, before there is some confirmation about settlement on the final name.

Pedro Alves: The commands that enables aren't even documented in the manual. Judging from that, I assume that only wdb users would ever really be using the --xdb switch. I think it's time to drop "support" for the --xdb switch too. I looked through the commands that that exposes, the only that looked potentially interesting was "go", but then it's just an alias for "tbreak+jump", which can easily be done with "define go...end".

2014-12-15Fix build with Python 3.4 (PR python/16784)Simon Marchi1-4/+4
The type of the function pointer PyOS_ReadlineFunctionPointer (part of the Python C API), which we use, slightly changed starting with Python 3.4. The signature went from PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, char *); to PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, const char *); The parameter that changed is the prompt text. This commits adjust gdb accordingly by making the prompt_arg parameter const, as well as the fallouts of that. I needed to rework how annotations are added to the prompt, since the it is now const. If annotations are enabled, it will make a copy of the prompt overwrite the prompt variable that is used throughout the function. Otherwise, no copy is done and the original prompt_arg value is passed. I changed the signature of deprecated_readline_hook. I would've changed any user of it, but it seems like nothing is using it, Built-tested with python 2.7.x, 3.3.y and 3.4.z. gdb/ChangeLog: * defs.h (gdb_readline): Constify argument.

2014-12-12the "compile" commandTom Tromey1-0/+28
This final patch adds the new "compile" command and subcommands, and all the machinery needed to make it work. A shared library supplied by gcc is used for all communications with gcc. Types and most aspects of symbols are provided directly by gdb to the compiler using this library. gdb provides some information about the user's code using plain text. Macros are emitted this way, and DWARF location expressions (and bounds for VLA) are compiled to C code. This hybrid approach was taken because, on the one hand, it is better to provide global declarations and such on demand; but on the other hand, for local variables, translating DWARF location expressions to C was much simpler than exporting a full compiler API to gdb -- the same result, only easier to implement, understand, and debug. In the ordinary mode, the user's expression is wrapped in a dummy function. After compilation, gdb inserts the resulting object code into the inferior, then calls this function. Access to local variables is provided by noting which registers are used by location expressions, and passing a structure of register values into the function. Writes to registers are supported by copying out these values after the function returns. This approach was taken so that we could eventually implement other more interesting features based on this same infrastructure; for example, we're planning to investigate inferior-side breakpoint conditions. gdb/ChangeLog 2014-12-12 Phil Muldoon <pmuldoon@redhat.com> Jan Kratochvil <jan.kratochvil@redhat.com> Tom Tromey <tromey@redhat.com> * NEWS: Update. * symtab.h (struct symbol_computed_ops) <generate_c_location>: New field. * p-lang.c (pascal_language_defn): Update. * opencl-lang.c (opencl_language_defn): Update. * objc-lang.c (objc_language_defn): Update. * m2-lang.c (m2_language_defn): Update. * language.h (struct language_defn) <la_get_compile_instance, la_compute_program>: New fields. * language.c (unknown_language_defn, auto_language_defn) (local_language_defn): Update. * jv-lang.c (java_language_defn): Update. * go-lang.c (go_language_defn): Update. * f-lang.c (f_language_defn): Update. * dwarf2loc.h (dwarf2_compile_property_to_c): Declare. * dwarf2loc.c (dwarf2_compile_property_to_c) (locexpr_generate_c_location, loclist_generate_c_location): New functions.

2014-10-17Delete Tru64 supportPedro Alves1-1/+0
This commit does most of the mechanical removal. IOW, the easy part. procfs.c isn't touched beyond removing a couple obvious bits that are guarded by a couple macros defined in config/alpha/nm-osf3.h. Going beyond that for procfs.c & co would be a harder excision that potentially affects Solaris. Some comments in the generic alpha code ABIs that may still be relevant and I wouldn't know what to do with them. That can always be done on a separate pass, preferably by someone who can test on alpha. A couple other spots have references to OSF/Tru64 and related files being removed, but it felt like removing them would make things worse, not better. We can revisit those when we next need to touch that code. I didn't remove a reference to osf in testsuite/lib/future.exp, as I believe that code is imported from DejaGNU. Built and tested on x86_64 Fedora 20, with --enable-targets=all.

Since no other platform needs this, I have removed the protection and the configury to support it. gdb/ 2014-08-07 Gary Benson <gbenson@redhat.com> * common/common-defs.h: Include errno.h. * defs.h: Do not include errno.h. * ada-typeprint.c: Likewise. * c-typeprint.c: Likewise. * core-regset.c: Likewise. * corefile.c: Likewise. * corelow.c: Likewise. * event-loop.c: Likewise. * f-typeprint.c: Likewise. * gnu-nat.c: Likewise. * go32-nat.c: Likewise. * i386gnu-nat.c: Likewise. * m2-typeprint.c: Likewise. * nat/linux-btrace.c: Likewise. * p-typeprint.c: Likewise. * procfs.c: Likewise. * remote-sim.c: Likewise. * rs6000-nat.c: Likewise. * target.c: Likewise. * typeprint.c: Likewise. * ui-file.c: Likewise. * valops.c: Likewise. * valprint.c: Likewise. gdb/gdbserver/ 2014-08-07 Gary Benson <gbenson@redhat.com> * configure.ac (AC_CHECK_HEADERS): Remove errno.h. * configure: Regenerate. * config.in: Likewise. * server.h: Do not include errno.h. * event-loop.c: Likewise. * hostio-errno.c: Likewise. * linux-low.c: Likewise. * remote-utils.c: Likewise. * spu-low.c: Likewise. * utils.c: Likewise. * gdbreplay.c: Unconditionally include errno.h.
