2015-01-23Use GCC5/DWARF5 DW_AT_noreturn to mark functions that don't return normally.Mark Wielaard1-1/+8
Add a flag field is_noreturn to struct func_type. Make calling_convention a small bit field to not increase the size of the struct. Set is_noreturn if the new GCC5/DWARF5 DW_AT_noreturn is set on a DW_TAG_subprogram. Use this information to warn the user before doing a finish or return from a function that does not return normally to its caller. (gdb) finish warning: Function endless does not return normally. Try to finish anyway? (y or n) (gdb) return warning: Function does not return normally to caller. Make endless return now? (y or n) gdb/ChangeLog * dwarf2read.c (read_subroutine_type): Set TYPE_NO_RETURN from DW_AT_noreturn. * gdbtypes.h (struct func_type): Add is_noreturn field flag.

2014-12-18Refactor gdbarch method print_float_infoYao Qi1-23/+21
This patch is to change print_float_info gdbarch method for the following two reasons, 1. we want to add a default implementation of print_float_info to dump the float pointer registers. It can be reused by backend to print something more than float point registers. 2. we want to simplify the caller of print_float_info, infcmd.c:print_float_info. gdb: 2014-12-18 Yao Qi <yao@codesourcery.com> * gdbarch.sh (print_float_info): Change its type from 'M' to 'm'. * gdbarch.c: Re-generated. * gdbarch.h: Likewise. * infcmd.c (default_print_float_info): New function.

2014-12-12Provide completer for "info registers"Andreas Arnez1-3/+9
Provide a new completion function for the argument of "info registers", "info all-registers", and the "lr" command in dbx mode. Without this patch the default symbol completer is used, which is more confusing than helpful. Also add a test for this new feature to "completion.exp": Determine the target's available set of registers/reggroups and compare this to the completion of "info registers ". For determining the available registers involve the new "maint print user-registers" command. gdb/ChangeLog: * completer.c: Include "target.h", "reggroups.h", and "user-regs.h". (reg_or_group_completer): New. * completer.h (reg_or_group_completer): Declare. * infcmd.c (_initialize_infcmd): Set reg_or_group_completer for the "info registers" and "info all-registers" commands and the dbx-mode "lr" command. gdb/testsuite/ChangeLog: * gdb.base/completion.exp: Add test for completion of "info registers ".
2014-10-17PR gdb/17471: Repeating a background command makes it foregroundPedro Alves1-53/+89
When we repeat a command, by just pressing <ret>, the input from the previous command is reused for the new command invocation. When an execution command strips the "&" out of its incoming argument string, to detect background execution, we poke a '\0' directly to the incoming argument string. Combine both, and a repeat of a background command loses the "&". This is actually only visible if args other than "&" are specified (e.g., "c 1&" or "next 2&" or "c -a&"), as in the special case of "&" alone (e.g. "c&") doesn't actually clobber the incoming string. Fix this by making strip_bg_char return a new string instead of poking a hole in the input string. New test included. Tested on x86_64 Fedora 20, native and gdbserver. gdb/ 2014-10-17 Pedro Alves <palves@redhat.com> PR gdb/17471 * infcmd.c (strip_bg_char): Change prototype and rewrite.

2014-10-17PR gdb/17300: Input after "c -a" crashes readline/GDBPedro Alves1-0/+18
If all threads in the target were already running when the user does "c -a", nothing puts the inferior's terminal settings in effect and removes stdin from the event loop, which we must when running a foreground command.

2014-09-13New command queue-signal.Doug Evans1-1/+58
If I want to change the signalled state of multiple threads it's a bit cumbersome to do with the "signal" command. What you really want is a way to set the signal state of the desired threads and then just do "continue". This patch adds a new command, queue-signal, to accomplish this. Basically "signal N" == "queue-signal N" + "continue". That's not precisely true in that "signal" can be used to inject any signal, including signals set to "nopass"; whereas "queue-signal" just queues the signal as if the thread stopped because of it. "nopass" handling is done when the thread is resumed which "queue-signal" doesn't do. One could add extra complexity to allow queue-signal to be used to deliver "nopass" signals like the "signal" command. I have no current need for it so in the interests of incremental complexity, I have left such support out and just have the code flag an error if one tries to queue a nopass signal. gdb/ChangeLog: * NEWS: Mention new "queue-signal" command. * infcmd.c (queue_signal_command): New function. (_initialize_infcmd): Add new queue-signal command. gdb/doc/ChangeLog: * gdb.texinfo (Signaling): Document new queue-signal command. gdb/testsuite/ChangeLog: * gdb.threads/queue-signal.c: New file. * gdb.threads/queue-signal.exp: New file.

2014-08-21infcmd.c: Remove stale TODOPedro Alves1-10/+0
This TODO has been stale for over 2 years. In bd5635a1 (1991), we already see the comment, when we only had a bare attach_command: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /* * TODO: * Should save/restore the tty state since it might be that the * program to be debugged was started on this tty and it wants * the tty in some state other than what we want. If it's running * on another terminal or without a terminal, then saving and * restoring the tty state is a harmless no-op. * This only needs to be done if we are attaching to a process. */ /* * attach_command -- * takes a program started up outside of gdb and ``attaches'' to it. * This stops it cold in its tracks and allows us to start tracing it. * For this to work, we must be able to send the process a * signal and we must have the same effective uid as the program. */ void attach_command (args, from_tty) char *args; int from_tty; { target_attach (args, from_tty); } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Later in b5a3d2aa (1992) target_terminal_init, etc. calls are added to attach_command, and in 7e97eb28 (1992) we see: + /* If we attached to the process, we might or might not be sharing + a terminal. Avoid printing error msg if we are unable to set our + terminal's process group to his process group ID. */ + if (!attach_flag) { + OOPSY ("ioctl TIOCSPGRP"); Clearly the TODO has been stale for a long while. I considered preserving the text elsewhere, but then thought the comments in inflow.c already have all the necessary info. gdb/ChangeLog: * infcmd.c (attach_command): Remove comment.

2014-07-29Fix PR 17206Yao Qi1-1/+3
As reported in PR 17206, an internal error is triggered when command until is executed. In infcmd.c:until_next_command, step_range_end is set to 'pc', if (!func) { struct bound_minimal_symbol msymbol = lookup_minimal_symbol_by_pc (pc); if (msymbol.minsym == NULL) error (_("Execution is not within a known function.")); tp->control.step_range_start = BMSYMBOL_VALUE_ADDRESS (msymbol); tp->control.step_range_end = pc; } and later in infrun.c:resume, the assert below is triggered in PR 17206. if (tp->control.may_range_step) { /* If we're resuming a thread with the PC out of the step range, then we're doing some nested/finer run control operation, like stepping the thread out of the dynamic linker or the displaced stepping scratch pad. We shouldn't have allowed a range step then. */ gdb_assert (pc_in_thread_step_range (pc, tp)); } In until_next_command, we set step range to [XXX, pc), so pc isn't within the range. pc_in_thread_step_range returns false and the assert is triggered. AFAICS, the range we want in until_next_command is [XXX, pc] instead of [XXX, pc), because we want to program step until greater than pc. This patch is to set step_range_end to 'pc + 1'. Running until-nodebug.exp with unpatched GDB will get the following fail, FAIL: gdb.base/until-nodebug.exp: until 2 (GDB internal error) and the fail goes away when the fix is applied. gdb: 2014-07-29 Yao Qi <yao@codesourcery.com> PR gdb/17206 * infcmd.c (until_next_command): Set step_range_end to PC + 1. gdb/testsuite: 2014-07-29 Yao Qi <yao@codesourcery.com> PR gdb/17206 * gdb.base/until-nodebug.exp: New.
2014-07-25Always pass signals to the right threadPedro Alves1-10/+54
Currently, GDB can pass a signal to the wrong thread in several different but related scenarios. E.g., if thread 1 stops for signal SIGFOO, the user switches to thread 2, and then issues "continue", SIGFOO is actually delivered to thread 2, not thread 1. This obviously messes up programs that use pthread_kill to send signals to specific threads. This has been a known issue for a long while. Back in 2008 when I made stop_signal be per-thread (2020b7ab), I kept the behavior -- see code in 'proceed' being removed -- wanting to come back to it later. The time has finally come now. The patch fixes this -- on resumption, intercepted signals are always delivered to the thread that had intercepted them. Another example: if thread 1 stops for a breakpoint, the user switches to thread 2, and then issues "signal SIGFOO", SIGFOO is actually delivered to thread 1, not thread 2, because 'proceed' first switches to thread 1 to step over its breakpoint... If the user deletes the breakpoint before issuing "signal FOO", then the signal is delivered to thread 2 (the current thread). "signal SIGFOO" can be used for two things: inject a signal in the program while the program/thread had stopped for none, bypassing "handle nopass"; or changing/suppressing a signal the program had stopped for. These scenarios are really two faces of the same coin, and GDB can't really guess what the user is trying to do. GDB might have intercepted signals in more than one thread even (see the new signal-command-multiple-signals-pending.exp test). At least in the inject case, it's obviously clear to me that the user means to deliver the signal to the currently selected thread, so best is to make the command's behavior consistent and easy to explain. Then, if the user is trying to suppress/change a signal the program had stopped for instead of injecting a new signal, but, the user had changed threads meanwhile, then she will be surprised that with: (gdb) continue Thread 1 stopped for signal SIGFOO. (gdb) thread 2 (gdb) signal SIGBAR ... GDB actually delivers SIGFOO to thread 1, and SIGBAR to thread 2 (with scheduler-locking off, which is the default, because then "signal" or any other resumption command resumes all threads). So the patch makes GDB detect that, and ask for confirmation: (gdb) thread 1 [Switching to thread 1 (Thread 10979)] (gdb) signal SIGUSR2 Note: Thread 3 previously stopped with signal SIGUSR2, User defined signal 2. Thread 2 previously stopped with signal SIGUSR1, User defined signal 1. Continuing thread 1 (the current thread) with specified signal will still deliver the signals noted above to their respective threads. Continue anyway?

2014-07-09Fix "attach" command vs user input racePedro Alves1-3/+16
On async targets, a synchronous attach is done like this: #1 - target_attach is called (PTRACE_ATTACH is issued) #2 - a continuation is installed #3 - we go back to the event loop #4 - target reports stop (SIGSTOP), event loop wakes up, and attach continuation is called #5 - among other things, the continuation calls target_terminal_inferior, which removes stdin from the event loop Note that in #3, GDB is still processing user input. If the user is fast enough, e.g., with something like: echo -e "attach PID\nset xxx=1" | gdb ... then the "set" command is processed before the attach completes. We get worse behavior even, if input is a tty and therefore readline/editing is enabled, with e.g.,: (gdb) attach PID\nset xxx=1 we then crash readline/gdb, with: Attaching to program: attach-wait-input, process 14537 readline: readline_callback_read_char() called with no handler! Aborted $ Fix this by calling target_terminal_inferior before #3 above.

2014-05-29enable target async by default; separate MI and target notions of asyncPedro Alves1-4/+2
This finally makes background execution commands possible by default. However, in order to do that, there's one last thing we need to do -- we need to separate the MI and target notions of "async". Unlike the CLI, where the user explicitly requests foreground vs background execution in the execution command itself (c vs c&), MI chose to treat "set target-async" specially -- setting it changes the default behavior of execution commands. So, we can't simply "set target-async" default to on, as that would affect MI frontends. Instead we have to make the setting MI-specific, and teach MI about sync commands on top of an async target. Because the "target" word in "set target-async" ends up as a potential source of confusion, the patch adds a "set mi-async" option, and makes "set target-async" a deprecated alias. Rather than make the targets always async, this patch introduces a new "maint set target-async" option so that the GDB developer can control whether the target is async. This makes it simpler to debug issues arising only in the synchronous mode; important because sync mode seems unlikely to go away. Unlike in previous revisions, "set target-async" does not affect this new maint parameter. The rationale for this is that then one can easily run the test suite in the "maint set target-async off" mode and have tests that enable mi-async fail just like they fail on non-async-capable targets. This emulation is exactly the point of the maint option. I had asked Tom in a previous iteration to split the actual change of the target async default to a separate patch, but it turns out that that is quite awkward in this version of the patch, because with MI async and target async decoupled (unlike in previous versions), if we don't flip the default at the same time, then just "set target-async on" alone never actually manages to do anything. It's best to not have that transitory state in the tree. Given "set target-async on" now only has effect for MI, the patch goes through the testsuite removing it from non-MI tests. MI tests are adjusted to use the new and less confusing "mi-async" spelling. 2014-05-29 Pedro Alves <palves@redhat.com> Tom Tromey <tromey@redhat.com> * NEWS: Mention "maint set target-async", "set mi-async", and that background execution commands are now always available. * target.h (target_async_permitted): Update comment. * target.c (target_async_permitted, target_async_permitted_1): Default to 1.

2014-03-12Factor out foreground/background execution command preparation.Pedro Alves1-136/+53
All execution commands currently have this pattern: /* If we must run in the background, but the target can't do it, error out. */ if (async_exec && !target_can_async_p ()) error (_("Asynchronous execution not supported on this target.")); /* If we are not asked to run in the bg, then prepare to run in the foreground, synchronously. */ if (!async_exec && target_can_async_p ()) { /* Simulate synchronous execution. */ async_disable_stdin (); } This patch factors that into a shared function. attach_command installs a cleanup to re-enable stdin, but that's not necessary, as per the comment in prepare_execution_command. In any case, if someday it turns out necessary, we have a single place to install it now. Tested on x86_64 Fedora 17, sync and async modes. gdb/ 2014-03-12 Pedro Alves <palves@redhat.com> * infcmd.c (prepare_execution_command): New function, factored out from several execution commands.

2014-03-12fix regressions with target-asyncTom Tromey1-11/+23
A patch in the target cleanup series caused a regression when using record with target-async. Version 4 of the patch is here: https://sourceware.org/ml/gdb-patches/2014-03/msg00159.html The immediate problem is that record supplies to_can_async_p and to_is_async_p methods, but does not supply a to_async method. So, when target-async is set, record claims to support async -- but if the underlying target does not support async, then the to_async method call will end up in that method's default implementation, namely tcomplain. This worked previously because the record target used to provide a to_async method; one that (erroneously, only at push time) checked the other members of the target stack, and then simply dropped to_async calls in the "does not implement async" case. My first thought was to simply drop tcomplain as the default for to_async. This works, but Pedro pointed out that the only reason record has to supply to_can_async_p and to_is_async_p is that these default to using the find_default_run_target machinery -- and these defaults are only needed by "run" and "attach". So, a nicer solution presents itself: change run and attach to explicitly call into the default run target when needed; and change to_is_async_p and to_can_async_p to default to "return 0". This makes the target stack simpler to use and lets us remove the method implementations from record. This is also in harmony with other plans for the target stack; namely trying to reduce the impact of find_default_run_target. This approach makes it clear that find_default_is_async_p is not needed -- it is asking whether a target that may not even be pushed is actually async, which seems like a nonsensical question. While an improvement, this approach proved to introduce the same bug when using the core target. Looking a bit deeper, the issue is that code in "attach" and "run" may need to use either the current target stack or the default run target -- but different calls into the target API in those functions could wind up querying different targets. This new patch makes the target to use more explicit in "run" and "attach". Then these commands explicitly make the needed calls against that target. This ensures that a single target is used for all relevant operations. This lets us remove a couple find_default_* functions from various targets, including the dummy target. I think this is a decent understandability improvement. One issue I see with this patch is that the new calls in "run" and "attach" are not very much like the rest of the target API. I think fundamentally this is due to bad factoring in the target API, which may need to be fixed for multi-target. Tackling that seemed ambitious for a regression fix. While working on this I noticed that there don't seem to be any test cases that involve both target-async and record, so this patch changes break-precsave.exp to add some. It also changes corefile.exp to add some target-async tests; these pass with current trunk and with this patch applied, but fail with the v1 patch. This patch differs from v4 in that it moves initialization of to_can_async_p and to_supports_non_stop into inf-child, adds some assertions to complete_target_initialization, and adds some comments to target.h.

2014-02-26start change to progspace independenceTom Tromey1-1/+1
This patch starts changing minimal symbols to be independent of the program space. Specifically, it adds a new objfile parameter to MSYMBOL_VALUE_ADDRESS and changes all the code to use it. This is needed so we can change gdb to apply the section offset when a minsym's address is computed, as opposed to baking the offsets into the symbol itself. A few spots still need the unrelocated address. For these, we introduce MSYMBOL_VALUE_RAW_ADDRESS. As a convenience, we also add the new macro BMSYMBOL_VALUE_ADDRESS, which computes the address of a bound minimal symbol. This just does the obvious thing with the fields. Note that this change does not actually enable program space independence. That requires more changes to gdb. However, to ensure that these changes compile properly, this patch does add the needed section lookup code to MSYMBOL_VALUE_ADDRESS -- it just ensures it has no effect at runtime by multiplying the offset by 0. 2014-02-26 Tom Tromey <tromey@redhat.com> * ada-lang.c (ada_main_name): Update.

2014-02-26change minsym representationTom Tromey1-1/+1
In a later patch we're going to change the minimal symbol address calculation to apply section offsets at the point of use. To make it simpler to catch potential problem spots, this patch changes the representation of minimal symbols and introduces new minimal-symbol-specific variants of the various accessors. This is necessary because it would be excessively ambitious to try to convert all the symbol types at once. The core of this change is just renaming a field in minimal_symbol; the rest is just a fairly mechanical rewording. 2014-02-26 Tom Tromey <tromey@redhat.com> * symtab.h (struct minimal_symbol) <mginfo>: Rename from ginfo.

2014-01-07Remove duplicated #include's from GDBHonggyu Kim1-1/+0
This patch simply removes duplicated #include statements in the gdb/ directory. If there are two duplicated #include statements, this patch keeps the first #include and removes the second. Those duplicates have been found by using the checkincludes.pl tool from the Linux kernel and double checked manually once again if the #include statements are affected by #ifdef macros. 2014-01-06 Honggyu Kim <hong.gyu.kim@lge.com> * ada-lang.c: Remove duplicated include statements. * alphabsd-nat.c: Ditto. * amd64-darwin-tdep.c: Ditto. * amd64fbsd-nat.c: Ditto. * auto-load.c: Ditto. * ax-gdb.c: Ditto. * breakpoint.c: Ditto. * dbxread.c: Ditto. * fork-child.c: Ditto. * gdb_usleep.c: Ditto. * i386-darwin-tdep.c: Ditto. * i386fbsd-nat.c: Ditto. * infcmd.c: Ditto. * inferior.c: Ditto. * jv-lang.c: Ditto. * linux-nat.c: Ditto. * linux-tdep.c: Ditto. * m68kbsd-nat.c: Ditto. * m68klinux-nat.c: Ditto. * microblaze-tdep.c: Ditto. * mips-linux-tdep.c: Ditto. * mn10300-tdep.c: Ditto. * nto-tdep.c: Ditto. * opencl-lang.c: Ditto. * osdata.c: Ditto. * printcmd.c: Ditto. * regcache.c: Ditto. * remote-m32r-sdi.c: Ditto. * remote.c: Ditto. * symfile.c: Ditto. * symtab.c: Ditto. * tilegx-linux-nat.c: Ditto. * tilegx-tdep.c: Ditto. * tracepoint.c: Ditto. * valops.c: Ditto. * vaxbsd-nat.c: Ditto. * windows-nat.c: Ditto. * xtensa-tdep.c: Ditto.

2013-10-25Make STARTUP_WITH_SHELL a runtime toggle -- add new "set/show ↵Pedro Alves1-1/+5
startup-with-shell" option. Occasionaly we hear about people having problems with GDB not being able to start programs (with "run"/"start"). GDB spawns a shell to start the program, and most often, it'll be the case that the problem is actually with the user's shell setup. GDB has code to disable the use of the shell to start programs. That's the STARTUP_WITH_SHELL macro that native targets could set to 0 in their nm.h file (though no target actually uses it nowadays). This patch makes that setting a run-time knob instead. This will be useful to quickly diagnose such shell issues, and might also come in handy at other times (such as when debugging the shell itself, if you don't have a different shell handy). gdb/ 2013-10-24 Pedro Alves <palves@redhat.com> * NEWS (New options): Mention set/show startup-with-shell. * config/alpha/nm-osf3.h (START_INFERIOR_TRAPS_EXPECTED): Set to 2 instead of 3. * fork-child.c (fork_inferior, startup_inferior): Handle 'set startup-with-shell'.

2013-10-02Print registers not saved in the frame as "<not saved>" instead of ↵Pedro Alves1-2/+2
"<optimized out>". Currently, in some scenarios, GDB prints <optimized out> when printing outer frame registers. An <optimized out> register is a confusing concept. What this really means is that the register is call-clobbered, or IOW, not saved by the callee. This patch makes GDB say that instead. Before patch: (gdb) p/x $rax $1 = <optimized out> (gdb) info registers rax rax <optimized out> After patch: (gdb) p/x $rax $1 = <not saved> (gdb) info registers rax rax <not saved> However, if for some reason the debug info describes a variable as being in such a register (**), we still want to print <optimized out> when printing the variable. IOW, <not saved> is reserved for inspecting registers at the machine level. The patch uses lval_register+optimized_out to encode the not saved registers, and makes it so that optimized out variables always end up in !lval_register values. ** See <https://sourceware.org/ml/gdb-patches/2012-08/msg00787.html>. Current/recent enough GCC doesn't mark variables/arguments as being in call-clobbered registers in the ranges corresponding to function calls, while older GCCs did. Newer GCCs will just not say where the variable is, so GDB will end up realizing the variable is optimized out. frame_unwind_got_optimized creates not_lval optimized out registers, so by default, in most cases, we'll see <optimized out>. value_of_register is the function eval.c uses for evaluating OP_REGISTER (again, $pc, etc.), and related bits. It isn't used for anything else. This function makes sure to return lval_register values. The patch makes "info registers" and the MI equivalent use it too. I think it just makes a lot of sense, as this makes it so that when printing machine registers ($pc, etc.), we go through a central function. We're likely to need a different encoding at some point, if/when we support partially saved registers. Even then, I think value_of_register will still be the spot to tag the intention to print machine register values differently. value_from_register however may also return optimized out lval_register values, so at a couple places where we're computing a variable's location from a dwarf expression, we convert the resulting value away from lval_register to a regular optimized out value.

Now the call in question, from within thread.c:print_thread_info, does pass in LOCATION as print_what, but print_stack_frame doesn't have the same check print_frame_info has. We could consider adding it, but setting these globals depending on print_what isn't very clean, IMO. What we have is two logically distinct operations mixed in the same function(s): #1 - print frame, in the format specified by {print_what, print_level and print_args}. #2 - We're displaying a frame to the user, and I want the default sal to point here, because the program stopped here, or the user did some context-changing command (up, down, etc.).

2013-05-23range stepping: gdbPedro Alves1-1/+7
This patch teaches GDB to take advantage of target-assisted range stepping. It adds a new 'r ADDR1,ADDR2' action to vCont (vCont;r), meaning, "step once, and keep stepping as long as the thread is in the [ADDR1,ADDR2) range". Rationale: When user issues the "step" command on the following line of source, a = b + c + d * e - a; GDB single-steps every single instruction until the program reaches a new different line. E.g., on x86_64, that line compiles to: 0x08048434 <+65>: mov 0x1c(%esp),%eax 0x08048438 <+69>: mov 0x30(%esp),%edx 0x0804843c <+73>: add %eax,%edx 0x0804843e <+75>: mov 0x18(%esp),%eax 0x08048442 <+79>: imul 0x2c(%esp),%eax 0x08048447 <+84>: add %edx,%eax 0x08048449 <+86>: sub 0x34(%esp),%eax 0x0804844d <+90>: mov %eax,0x34(%esp) 0x08048451 <+94>: mov 0x1c(%esp),%eax and the following is the RSP traffic between GDB and GDBserver: --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:3c840408;thread:p2e13.2e13;core:1; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:3e840408;thread:p2e13.2e13;core:2; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:42840408;thread:p2e13.2e13;core:2; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:47840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:49840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:4d840408;thread:p2e13.2e13;core:0; --> vCont;s:p2e13.2e13;c <-- T0505:68efffbf;04:30efffbf;08:51840408;thread:p2e13.2e13;core:0; IOW, a lot of roundtrips between GDB and GDBserver. If we add a new command to the RSP, meaning "keep stepping and don't report a stop until the program goes out of the [0x08048434, 0x08048451) address range", then the RSP traffic can be reduced down to: --> vCont;r8048434,8048451:p2db0.2db0;c <-- T0505:68efffbf;04:30efffbf;08:51840408;thread:p2db0.2db0;core:1; As number of packets is reduced dramatically, the performance of stepping source lines is much improved. In case something is wrong with range stepping on the stub side, the debug info or even gdb, this adds a "set/show range-stepping" command to be able to turn range stepping off. gdb/ 2013-05-23 Yao Qi <yao@codesourcery.com> Pedro Alves <palves@redhat.com> * gdbthread.h (struct thread_control_state) <may_range_step>: New field. * infcmd.c (step_once, until_next_command): Enable range stepping. * infrun.c (displaced_step_prepare): Disable range stepping.

2013-04-10make -gdb-exit call disconnect_tracing too, and don't lose history if the ↵Pedro Alves1-2/+5
target errors on "quit" Gareth mentions in PR gdb/15275: "The MI '-gdb-exit' command mi_cmd_gdb_exit() never calls disconnect_tracing() and therefore exits correctly." It should, so to get out of tfind mode, as quit may detach instead of kill, and we don't want to confuse the memory/register accesses etc. of the detach process. So we should push down the disconnect tracing bits at least to quit_force. But we can't as is, as that would swallow the error thrown by answering "no" to: Trace is running but will stop on detach; detach anyway? (y or n) So to address that, we split disconnect_tracing in two. One part that does the query, and another part that does the rest, and we make quit_force call the latter. Looking at quit_force, it does several things, some of which are a bit independent of the others. It first kills/detaches, and then writes history, and then runs the final cleanups. It seems better to me to do each of these things even if the previous thing throws. E.g., as is, if something throws while detaching, then we skip writing history.

2013-03-13Constify strings in tracepoint.c, lookup_cmd and the completers.Pedro Alves1-1/+1
This is sort of a continuation of Keith's parse_exp_1 constification patch. It started out by undoing these bits: @@ -754,9 +754,12 @@ validate_actionline (char **line, struct tmp_p = p; for (loc = t->base.loc; loc; loc = loc->next) { - p = tmp_p; - exp = parse_exp_1 (&p, loc->address, + const char *q; + + q = tmp_p; + exp = parse_exp_1 (&q, loc->address, block_for_pc (loc->address), 1); + p = (char *) q; and progressively making more things const upwards, fixing fallout, rinse repeat, until GDB built again (--enable-targets=all). That ended up constifying lookup_cmd/add_cmd and (lots of) friends, and the completers. I didn't try to constify the command hooks themselves, because I know upfront there are commands that write to the command string argument, and I think I managed to stop at a nice non-hacky split point already. I think the only non-really-super-obvious changes are tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions. The rest is just mostly about 'char *' => 'const char *', 'char **'=> 'const char **', and the occasional (e.g., deprecated_cmd_warning) case of 'char **'=> 'const char *', where/when I noticed that nothing actually cares about the pointer to pointer output.
