2019-08-07Make first and last lines of 'command help documentation' consistent.Philippe Waroquiers1-2/+3
With this patch, the help docs now respect 2 invariants: * The first line of a command help is terminated by a '.' character. * The last character of a command help is not a newline character. Note that the changes for the last invariant were done by Tom, as part of : [PATCH] Remove trailing newlines from help text https://sourceware.org/ml/gdb-patches/2019-06/msg00050.html but some occurrences have been re-introduced since then. Some help docs had to be rephrased/restructured to respect the above invariants. Before this patch, print_doc_line was printing the first line of a command help documentation, but stopping at the first '.' or ',' character. This was giving inconsistent results : * The first line of command helps was sometimes '.' terminated, sometimes not. * The first line of command helps was not always designed to be readable/understandable/unambiguous when stopping at the first '.' or ',' character. This e.g. created the following inconsistencies/problems: < catch exception -- Catch Ada exceptions < catch handlers -- Catch Ada exceptions < catch syscall -- Catch system calls by their names < down-silently -- Same as the `down' command while the new help is: > catch exception -- Catch Ada exceptions, when raised. > catch handlers -- Catch Ada exceptions, when handled. > catch syscall -- Catch system calls by their names, groups and/or numbers. > down-silently -- Same as the `down' command, but does not print anything. Also, the command help doc should not be terminated by a newline character, but this was not respected by all commands. The cli-option -OPT framework re-introduced some occurences. So, the -OPT build help framework was changed to not output newlines at the end of %OPTIONS% replacement. This patch changes the help documentations to ensure the 2 invariants given above. It implied to slightly rephrase or restructure some help docs. Based on the above invariants, print_doc_line (called by 'apropos' and 'help' commands to print the first line of a command help) now outputs the full first line of a command help. This all results in a lot of small changes in the produced help docs. There are less code changes than changes in the help docs, as a lot of docs are produced by some code (e.g. the remote packet usage settings). gdb/ChangeLog 2019-08-07 Philippe Waroquiers <philippe.waroquiers@skynet.be> * cli/cli-decode.h (print_doc_line): Add for_value_prefix argument. * cli/cli-decode.c (print_doc_line): Likewise.

2019-07-09Rename common to gdbsupportTom Tromey1-4/+4
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.

2019-06-11Remove trailing newlines from help textTom Tromey1-2/+2
I noticed recently that some command had a trailing newline in its "help" output. So, I temporarily hacked cli-decode.c to print something when a new command was installed that had a trailing newline in its help message, and wrote this patch, which removes all the ones I could find this way. (There could still be a few more in *-nat files.)

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.
2019-05-29Add "set print finish"Tom Tromey1-4/+29
A user wanted to be able to disable the display of the value when using "finish" -- but still have the value entered into the value history in case it was useful later on. Part of the rationale here is that sometimes the value might be quite large, or expensive to display (in their case this was compounded by a rogue pretty-printer). This patch implements this idea. gdb/ChangeLog 2019-05-29 Tom Tromey <tromey@adacore.com> * NEWS: Add entry. * infcmd.c (print_return_value_1): Handle finish_print option.

2019-04-09Use -qualified flag when setting temporary breakpoint in start commandSimon Marchi1-1/+4
When using the "start" command, GDB puts a temporary breakpoint on the "main" symbol (we literally invoke the tbreak command). However, since it does wild matching by default, it also puts a breakpoint on any C++ method or "main" function in a namespace. For example, when debugging GDB, it creates a total of 24 locations: (gdb) start Temporary breakpoint 1 at 0x198c1e9: main. (24 locations) as there are a bunch of methods called main in the selftests, such as selftests::string_view::capacity_1::main() If such method was called in the constructor of a global object, or a function marked with the attribute "constructor", then we would stop at the wrong place. Also, this causes a few extra symtabs (those that contain the "wrong" mains) to be expanded for nothing. The dummiest, most straightforward solution is to add -qualified when invoking tbreak. With this patch, "start" creates a single-location breakpoint, as expected. I copied the start.exp test to start-cpp.exp and made it use a C++ test file, which contains two main functions. The new test verifies that the output of "start" is the output we get when we set a single-location breakpoint. gdb/ChangeLog: * infcmd.c (run_command_1): Pass -qualified to tbreak when usind the "start" command. gdb/testsuite/ChangeLog: * gdb.base/start-cpp.exp: New file. * gdb.base/start-cpp.cc: New file.
2019-04-08Replace throw_exception with throw in some casesTom Tromey1-1/+1
This replaces throw_exception with "throw;" when possible. This was written by script. The rule that is followed is that uses of the form: catch (... &name) { ... throw_exception (name); } ... can be rewritten. This should always be safe, because exceptions are caught by const reference, and therefore can't be modified in the body of the catch. gdb/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * valops.c (value_rtti_indirect_type): Replace throw_exception with throw. * tracefile-tfile.c (tfile_target_open): Replace throw_exception with throw. * thread.c (thr_try_catch_cmd): Replace throw_exception with throw. * target.c (target_translate_tls_address): Replace throw_exception with throw. * stack.c (frame_apply_command_count): Replace throw_exception with throw. * solib-spu.c (append_ocl_sos): Replace throw_exception with throw. * s390-tdep.c (s390_frame_unwind_cache): Replace throw_exception with throw. * rs6000-tdep.c (rs6000_frame_cache) (rs6000_epilogue_frame_cache): Replace throw_exception with throw. * remote.c: Replace throw_exception with throw. * record-full.c (record_full_message, record_full_wait_1) (record_full_restore): Replace throw_exception with throw. * record-btrace.c: (get_thread_current_frame_id, record_btrace_start_replaying) (cmd_record_btrace_bts_start, cmd_record_btrace_pt_start) (cmd_record_btrace_start): Replace throw_exception with throw. * parse.c (parse_exp_in_context_1): Replace throw_exception with throw. * linux-nat.c (detach_one_lwp, linux_resume_one_lwp) (resume_stopped_resumed_lwps): Replace throw_exception with throw. * linespec.c: (find_linespec_symbols): Replace throw_exception with throw. * infrun.c (displaced_step_prepare, resume): Replace throw_exception with throw. * infcmd.c (post_create_inferior): Replace throw_exception with throw. * inf-loop.c (inferior_event_handler): Replace throw_exception with throw. * i386-tdep.c (i386_frame_cache, i386_epilogue_frame_cache) (i386_sigtramp_frame_cache): Replace throw_exception with throw. * frame.c (frame_unwind_pc, get_prev_frame_if_no_cycle) (get_prev_frame_always, get_frame_pc_if_available) (get_frame_address_in_block_if_available, get_frame_language): Replace throw_exception with throw. * frame-unwind.c (frame_unwind_try_unwinder): Replace throw_exception with throw. * eval.c (fetch_subexp_value, evaluate_var_value) (evaluate_funcall, evaluate_subexp_standard): Replace throw_exception with throw. * dwarf2loc.c (call_site_find_chain) (dwarf2_evaluate_loc_desc_full, dwarf2_locexpr_baton_eval): Replace throw_exception with throw. * dwarf2-frame.c (dwarf2_frame_cache): Replace throw_exception with throw. * darwin-nat.c (darwin_attach_pid): Replace throw_exception with throw. * cp-abi.c (baseclass_offset): Replace throw_exception with throw. * completer.c (complete_line_internal): Replace throw_exception with throw. * compile/compile-object-run.c (compile_object_run): Replace throw_exception with throw. * cli/cli-script.c (process_next_line): Replace throw_exception with throw. * btrace.c (btrace_compute_ftrace_pt, btrace_compute_ftrace) (btrace_enable, btrace_maint_update_pt_packets): Replace throw_exception with throw. * breakpoint.c (create_breakpoint, save_breakpoints): Replace throw_exception with throw. * break-catch-throw.c (re_set_exception_catchpoint): Replace throw_exception with throw. * amd64-tdep.c (amd64_frame_cache, amd64_sigtramp_frame_cache) (amd64_epilogue_frame_cache): Replace throw_exception with throw. * aarch64-tdep.c (aarch64_make_prologue_cache) (aarch64_make_stub_cache): Replace throw_exception with throw. gdb/gdbserver/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * linux-low.c (linux_detach_one_lwp): Replace throw_exception with throw.

2019-04-08Rename gdb exception typesTom Tromey1-2/+2
This renames the gdb exception types. The old types were only needed due to the macros in common-exception.h that are now gone.

2018-11-22Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc.Pedro Alves1-49/+20
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.

2018-10-21Introduce gdbarch_num_cooked_regsSimon Marchi1-14/+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.

This change/patch substitues BLOCK_ENTRY_PC for BLOCK_START in places where BLOCK_START is used to obtain the address at which execution should enter the block. Since blocks can now contain non-contiguous ranges, the BLOCK_START - which is still be the very lowest address in the block - might not be the same as BLOCK_ENTRY_PC.

2018-07-26[gdb/breakpoints] Fix sigsegv in info prog at exec catchpointTom de Vries1-1/+1
With the test-case contained in this patch and compiled for debug we run into a segfault with trunk gdb: ... $ gdb catch-follow-exec -batch -ex "catch exec" \ -ex "set follow-exec-mode new" -ex "run" -ex "info prog" Catchpoint 1 (exec) process xxx is executing new program: /usr/bin/ls [New inferior 2 (process 0)] [New process xxx] Thread 2.1 "ls" hit Catchpoint 1 (exec'd /usr/bin/ls), in _start () from /lib64/ld-linux-x86-64.so.2 Segmentation fault (core dumped) ... The patch fixes the segfault by returning an error in info_program_command if get_last_target_status returns minus_one_ptid. The test-case is non-standard, because the standard approach runs into PR23368, a problem with gdb going to the background. Build and reg-tested on x86_64-linux. 2018-07-26 Tom de Vries <tdevries@suse.de> PR breakpoints/23366 * infcmd.c (info_program_command): Handle ptid == minus_one_ptid. * gdb.base/catch-follow-exec.c: New test. * gdb.base/catch-follow-exec.exp: New file.

2018-06-28gdb: Eliminate the 'stop_pc' globalPedro Alves1-7/+5
In my multi-target work, I need to add a few more scoped_restore_current_thread and switch_to_thread calls in some places, and in some lower-level places I was fighting against the fact that switch_to_thread reads/refreshes the stop_pc global. Instead of piling on workarounds, let's just finally eliminate the stop_pc global. We already have the per-thread thread_info->suspend.stop_pc field, so it's mainly a matter of using that more/instead. gdb/ChangeLog: 2018-06-28 Pedro Alves <palves@redhat.com> * gdbthread.h (struct thread_suspend_state) <stop_pc>: Extend comments.

2018-06-21Use thread_info and inferior pointers more throughoutPedro Alves1-19/+22
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.

2018-06-14[gdb/cli] Honour 'print pretty' when printing result of finish commandTom de Vries1-1/+1
Consider this testcase: ... struct s { int a; int b; }; struct s foo () { struct s r; r.a = 1; r.b = 2; return r; } int main (void) { struct s v; v = foo (); return v.a + v.b; } ... When we compile it with -g, load the exec with gdb, and run till the end of foo, we can print r: ... (gdb) p r $1 = {a = 1, b = 2} ... and by setting pretty printing to on, we can get the fields of r printed each on its own line: ... (gdb) set print pretty (gdb) p r $2 = { a = 1, b = 2 } ... However, when we finish foo, the printed function result value is not using the pretty printing setting: ... (gdb) finish Run till exit from #0 foo () at test.c:11 0x00000000004004c1 in main () at test.c:18 18 v = foo (); Value returned is $3 = {a = 1, b = 2} ... This patch fixes that by using get_user_print_options instead of get_no_prettyformat_print_options in print_return_value_1, which gives us: ... (gdb) finish Run till exit from #0 foo () at test.c:11 0x00000000004004c1 in main () at test.c:18 18 v = foo (); Value returned is $2 = { a = 1, b = 2 } ...

2018-06-07target_stack -> current_top_target() throughoutPedro Alves1-9/+9
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.

2018-05-03Convert struct target_ops to C++Pedro Alves1-18/+18
I.e., use C++ virtual methods and inheritance instead of tables of function pointers. Unfortunately, there's no way to do a smooth transition. ALL native targets in the tree must be converted at the same time. I've tested all I could with cross compilers and with help from GCC compile farm, but naturally I haven't been able to test many of the ports. Still, I made a best effort to port everything over, and while I expect some build problems due to typos and such, which should be trivial to fix, I don't expect any design problems. * Implementation notes: - The flattened current_target is gone. References to current_target or current_target.beneath are replaced with references to target_stack (the top of the stack) directly. - To keep "set debug target" working, this adds a new debug_stratum layer that sits on top of the stack, prints the debug, and delegates to the target beneath. In addition, this makes the shortname and longname properties of target_ops be virtual methods instead of data fields, and makes the debug target defer those to the target beneath. This is so that debug code sprinkled around that does "if (debugtarget) ..." can transparently print the name of the target beneath. A patch later in the series actually splits out the shortname/longname methods to a separate structure, but I preferred to keep that chance separate as it is associated with changing a bit the design of how targets are registered and open. - Since you can't check whether a C++ virtual method is overridden, the old method of checking whether a target_ops implements a method by comparing the function pointer must be replaced with something else. Some cases are fixed by adding a parallel "can_do_foo" target_ops methods. E.g.,: + for (t = target_stack; t != NULL; t = t->beneath) { - if (t->to_create_inferior != NULL) + if (t->can_create_inferior ()) break; } Others are fixed by changing void return type to bool or int return type, and have the default implementation return false or -1, to indicate lack of support. - make-target-delegates was adjusted to generate C++ classes and methods. It needed tweaks to grok "virtual" in front of the target method name, and for the fact that methods are no longer function pointers. (In particular, the current code parsing the return type was simple because it could simply parse up until the '(' in '(*to_foo)'. It now generates a couple C++ classes that inherit target_ops: dummy_target and debug_target. Since we need to generate the class declarations as well, i.e., we need to emit methods twice, we now generate the code in two passes. - The core_target global is renamed to avoid conflict with the "core_target" class. - ctf/tfile targets init_tracefile_ops is replaced by a base class that is inherited by both ctf and tfile. - bsd-uthread The bsd_uthread_ops_hack hack is gone. It's not needed because nothing was extending a target created by bsd_uthread_target. - remote/extended-remote targets This is a first pass, just enough to C++ify target_ops. A later pass will convert more free functions to methods, and make remote_state be truly per remote instance, allowing multiple simultaneous instances of remote targets. - inf-child/"native" is converted to an actual base class (inf_child_target), that is inherited by all native targets. - GNU/Linux The old weird double-target linux_ops mechanism in linux-nat.c, is gone, replaced by adding a few virtual methods to linux-nat.h's target_ops, called low_XXX, that the concrete linux-nat implementations override. Sort of like gdbserver's linux_target_ops, but simpler, for requiring only one target_ops-like hierarchy, which spares implementing the same method twice when we need to forward the method to a low implementation. The low target simply reimplements the target_ops method directly in that case. There are a few remaining linux-nat.c hooks that would be better converted to low_ methods like above too. E.g.: linux_nat_set_new_thread (t, x86_linux_new_thread); linux_nat_set_new_fork (t, x86_linux_new_fork); linux_nat_set_forget_process That'll be done in a follow up patch. - We can no longer use functions like x86_use_watchpoints to install custom methods on an arbitrary base target. The patch replaces instances of such a pattern with template mixins. For example memory_breakpoint_target defined in target.h, or x86_nat_target in x86-nat.h. - linux_trad_target, MIPS and Alpha GNU/Linux The code in the new linux-nat-trad.h/c files which was split off of inf-ptrace.h/c recently, is converted to a C++ base class, and used by the MIPS and Alpha GNU/Linux ports. - BSD targets The $architecture x NetBSD/OpenBSD/FreeBSD support matrix complicates things a bit. There's common BSD target code, and there's common architecture-specific code shared between the different BSDs. Currently, all that is stiched together to form a final target, via the i386bsd_target, x86bsd_target, fbsd_nat_add_target functions etc. This introduces new fbsd_nat_target, obsd_nat_target and nbsd_nat_target classes that serve as base/prototype target for the corresponding BSD variant. And introduces generic i386/AMD64 BSD targets, to be used as template mixin to build a final target. Similarly, a generic SPARC target is added, used by both BSD and Linux ports. - bsd_kvm_add_target, BSD libkvm target I considered making bsd_kvm_supply_pcb a virtual method, and then have each port inherit bsd_kvm_target and override that method, but that was resulting in lots of unjustified churn, so I left the function pointer mechanism alone. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> John Baldwin <jhb@freebsd.org> * target.h (enum strata) <debug_stratum>: New.

2018-04-25Fix new inferior events outputPedro Alves1-2/+5
Since f67c0c917150 ("Enable 'set print inferior-events' and improve detach/fork/kill/exit messages"), when detaching a remote process, we get, for detach against a remote target: (gdb) detach Detaching from program: ...., process 5388 Ending remote debugging. [Inferior 1 (Thread 5388.5388) detached] ^^^^^^^^^^^^^^^^ That is incorrect, for it is printing a thread id as string while we should be printing the process id instead. I.e., either one of: [Inferior 1 (process 5388) detached] [Inferior 1 (Remote target) detached] depending on remote stub support for the multi-process extensions. Similarly, after killing a process, we're printing thread ids while we should be printing process ids. E.g., on native GNU/Linux: (gdb) k Kill the program being debugged? (y or n) y [Inferior 1 (Thread 0x7ffff7faa8c0 (LWP 30721)) has been killed] ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ while it should have been: Kill the program being debugged? (y or n) y [Inferior 1 (process 30721) has been killed] ^^^^^^^^^^^^^ There's a wording inconsistency between detach and kill: [Inferior 1 (process 30721) has been killed] [Inferior 1 (process 30721) detached] Given we were already saying "detached" instead of "has been detached", and we used to say just "exited", and given that the "has been" doesn't really add any information, this commit changes the message to just "killed": [Inferior 1 (process 30721) killed] gdb/ChangeLog: 2018-04-25 Pedro Alves <palves@redhat.com> * infcmd.c (kill_command): Print the pid as string, not the whole thread's ptid.

2018-04-24Enable 'set print inferior-events' and improve detach/fork/kill/exit messagesSergio Durigan Junior1-0/+8
This patch aims to turn 'set print inferior-events' always on, and do some cleanup on the messages printed by GDB when various inferior events happen (attach, detach, fork, kill, exit). To make sure that the patch is correct, I've tested it with a handful of combinations of 'set follow-fork-mode', 'set detach-on-fork' and 'set print inferior-events'. In the end, I decided to make my hand-made test into an official testcase. More on that below. Using the following program as an example: #include <unistd.h> int main () { fork (); return 0; } We see the following outputs from the patched GDB: - With 'set print inferior-events on': (gdb) r Starting program: a.out [Detaching after fork from child process 27749] [Inferior 1 (process 27745) exited normally] (gdb) - With 'set print inferior-events off': (gdb) r Starting program: a.out [Inferior 1 (process 27823) exited normally] (gdb) Comparing this against an unpatched GDB: - With 'set print inferior-events off' and 'set follow-fork-mode child': (gdb) r Starting program: a.out [Inferior 2 (process 5993) exited normally] (gdb) Compare this against an unpatched GDB: (unpatched-gdb) r Starting program: a.out [New process 5702] [Inferior 2 (process 5702) exited normally] (unpatched-gdb) It is possible to notice that, in this scenario, the patched GDB will lose the '[New process %d]' message. - With 'set print inferior-events on', 'set follow-fork-mode child' and 'set detach-on-fork on': (gdb) r Starting program: a.out [Attaching after process 27905 fork to child process 27909] [New inferior 2 (process 27909)] [Detaching after fork from parent process 27905] [Inferior 1 (process 27905) detached] [Inferior 2 (process 27909) exited normally] (gdb) Compare this output with an unpatched GDB, using the same settings: (unpatched-gdb) r Starting program: a.out [New inferior 28033] [Inferior 28029 detached] [New process 28033] [Inferior 2 (process 28033) exited normally] [Inferior 28033 exited] (unpatched-gdb) As can be seen above, I've also made a few modifications to messages that are printed when 'set print inferior-events' is on. For example, a few of the messages did not contain the '[' and ']' as prefix/suffix, which led to a few inconsistencies like: Attaching after process 22995 fork to child process 22999. [New inferior 22999] Detaching after fork from child process 22999. [Inferior 22995 detached] [Inferior 2 (process 22999) exited normally] So I took the opportunity and included the square brackets where applicable. I have also made the existing messages more uniform, by always printing "Inferior %d (process %d)..." where applicable. This makes it easier to identify the inferior number and the PID number from the messages. As suggested by Pedro, the "[Inferior %d exited]" message from 'exit_inferior' has been removed, because it got duplicated when 'inferior-events' is on. I'm also using the 'add_{thread,inferior}_silent' versions (instead of their verbose counterparts) on some locations, also to avoid duplicated messages. For example, a patched GDB with 'set print inferior-events on', 'set detach-on-fork on' and 'set follow-fork-mode child', but using 'add_thread', would print: (gdb) run Starting program: a.out [Attaching after process 25088 fork to child process 25092.] [New inferior 25092] <--- duplicated [Detaching after fork from child process 25092.] [Inferior 25088 detached] [New process 25092] <--- duplicated [Inferior 2 (process 25092) exited normally] But if we use 'add_thread_silent' (with the same configuration as before): (gdb) run Starting program: a.out [Attaching after process 31606 fork to child process 31610] [New inferior 2 (process 31610)] [Detaching after fork from parent process 31606] [Inferior 1 (process 31606) detached] [Inferior 2 (process 31610) exited normally] As for the tests, the configuration options being exercised are: - follow-fork-mode: child/parent - detach-on-fork: on/off - print inferior-events: on/off It was also necessary to perform adjustments on several testcases, because the expected messages changed considerably.

2018-03-19Convert observers to C++Tom Tromey1-2/+2
This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

2018-02-21No longer create readonly regcacheYao Qi1-3/+3
Nowadays, we create a readonly regcache in get_return_value, and pass it to gdbarch_return_value to get the return value. In theory, we can pass a readable_regcache instance and get the return value, because we don't need to modify the regcache. Unfortunately, gdbarch_return_value is designed to multiplex regcache, according to READBUF and WRITEBUF. # If READBUF is not NULL, extract the return value and save it in this # buffer. # # If WRITEBUF is not NULL, it contains a return value which will be # stored into the appropriate register. In fact, gdbarch_return_value should be split to three functions, 1) only return return_value_convention, 2) pass regcache_readonly and readbuf, 3) pass regcache and writebuf. These changes are out of the scope of this patch series, so I pass regcache to gdbarch_return_value even for read, and trust each gdbarch backend doesn't modify regcache. gdb: 2018-02-21 Yao Qi <yao.qi@linaro.org> * infcmd.c (get_return_value): Let stop_regs point to get_current_regcache. * regcache.c (regcache::regcache): Remove.

Currently, commands such as "info reg", "info all-reg", as well as register window in the TUI print badly aligned columns, like here: eax 0x1 1 ecx 0xffffd3e0 -11296 edx 0xffffd404 -11260 ebx 0xf7fa5ff4 -134586380 esp 0xffffd390 0xffffd390 ebp 0xffffd3c8 0xffffd3c8 esi 0x0 0 edi 0x0 0 eip 0x8048b60 0x8048b60 <main+16> eflags 0x286 [ PF SF IF ] cs 0x23 35 ss 0x2b 43 ds 0x2b 43 es 0x2b 43 fs 0x0 0 gs 0x63 99 After this patch, these commands print the third column values consistently aligned one under another, provided the second column is not too long. Originally, the third column was (attempted to be) aligned using a simple tab character. This patch changes the alignment to spaces only. The tests checking the output and expecting the single tab have been fixed in a previous patch, so this change doesn't break any. gdb/ChangeLog: * infcmd.c (default_print_one_register_info): Align natural-format column values consistently one under another.

2018-01-30Per-inferior target_terminal state, fix PR gdb/13211, morePedro Alves1-1/+1
In my multi-target branch I ran into problems with GDB's terminal handling that exist in master as well, with multi-inferior debugging. This patch adds a testcase for said problems (gdb.multi/multi-term-settings.exp), fixes the problems, fixes PR gdb/13211 as well (and adds a testcase for that too, gdb.base/interrupt-daemon.exp). The basis of the problem I ran into is the following. Consider a scenario where you have: - inferior 1 - started with "attach", process is running on some other terminal. - inferior 2 - started with "run", process is sharing gdb's terminal. In this scenario, when you stop/resume both inferiors, you want GDB to save/restore the terminal settings of inferior 2, the one that is sharing GDB's terminal. I.e., you want inferior 2 to "own" the terminal (in target_terminal::is_ours/target_terminal::is_inferior sense). Unfortunately, that's not what you get currently. Because GDB doesn't know whether an attached inferior is actually sharing GDB's terminal, it tries to save/restore its settings anyway, ignoring errors. In this case, this is pointless, because inferior 1 is running on a different terminal, but GDB doesn't know better. And then, because it is only possible to have the terminal settings of a single inferior be in effect at a time, or make one inferior/pgrp be the terminal's foreground pgrp (aka, only one inferior can "own" the terminal, ignoring fork children here), if GDB happens to try to restore the terminal settings of inferior 1 first, then GDB never restores the terminal settings of inferior 2. This patch fixes that and a few things more along the way: - Moves enum target_terminal::terminal_state out of the target_terminal class (it's currently private) and makes it a scoped enum so that it can be easily used elsewhere. - Replaces the inflow.c:terminal_is_ours boolean with a target_terminal_state variable. This allows distinguishing is_ours and is_ours_for_output states. This allows finally making child_terminal_ours_1 do something with its "output_only" parameter. - Makes each inferior have its own copy of the is_ours/is_ours_for_output/is_inferior state. - Adds a way for GDB to tell whether the inferior is sharing GDB's terminal. Works best on Linux and Solaris; the fallback works just as well as currently. - With that, we can remove the inf->attach_flag tests from child_terminal_inferior/child_terminal_ours. - Currently target_ops.to_ours is responsible for both saving the current inferior's terminal state, and restoring gdb's state. Because each inferior has its own terminal state (possibly handled by different targets in a multi-target world, even), we need to split the inferior-saving part from the gdb-restoring part. The patch adds a new target_ops.to_save_inferior target method for that. - Adds a new target_terminal::save_inferior() function, so that sequences like: scoped_restore_terminal_state save_state; target_terminal::ours_for_output (); ... restore back inferiors that were target_terminal_state::is_inferior before back to is_inferior, and leaves inferiors that were is_ours alone. - Along the way, this adds a default implementation of target_pass_ctrlc to inflow.c (for inf-child.c), that handles passing the Ctrl-C to a process running on GDB's terminal or to some other process otherwise. - Similarly, adds a new target default implementation of target_interrupt, for the "interrupt" command. The current implementation of this hook in inf-ptrace.c kills the whole process group, but that's incorrect/undesirable because we may not be attached to all processes in the process group. And also, it's incorrect because inferior_process_group() doesn't really return the inferior's real process group id if the inferior is not a process group leader... This is the cause of PR gdb/13211 [1], which this patch fixes. While at it, that target method's "ptid" parameter is eliminated, because it's not really used. - A new test is included that exercises and fixes PR gdb/13211, and also fixes a GDB issue reported on stackoverflow that I ran into while working on this [2]. The problem is similar to PR gdb/13211, except that it also triggers with Ctrl-C. When debugging a daemon (i.e., a process that disconnects from the controlling terminal and is not a process group leader, then Ctrl-C doesn't work, you just can't interrupt the inferior at all, resulting in a hung debug session. The problem is that since the inferior is no longer associated with gdb's session / controlling terminal, then trying to put the inferior in the foreground fails. And so Ctrl-C never reaches the inferior directly. pass_signal is only used when the inferior is attached, but that is not the case here. This is fixed by the new child_pass_ctrlc. Without the fix, the new interrupt-daemon.exp testcase fails with timeout waiting for a SIGINT that never arrives.

2018-01-19Pass inferior down to target_detach and to_detachSimon Marchi1-1/+1
The to_detach target_ops method implementations are currently expected to work on current_inferior/inferior_ptid. In order to make things more explicit, and remove some "shadow" parameter passing through globals, this patch adds an "inferior" parameter to to_detach. Implementations will be expected to use this instead of relying on the global. However, to keep things simple, this patch only does the minimum that is necessary to add the parameter. The following patch gives an example of how one such implementation would be adapted. If the approach is deemed good, we can then look into adapting more implementations. Until then, they'll continue to work as they do currently. gdb/ChangeLog: * target.h (struct target_ops) <to_detach>: Add inferior parameter.

2018-01-19Remove args from target detachSimon Marchi1-1/+1
I was looking into adding a parameter to target_detach, and was wondering what the args parameter was. It seems like in the distant past, it was possible to specify a signal number when detaching. That signal was injected in the process before it was detached. There is an example of code handling this in linux_nat_detach. With today's GDB, I can't get this to work. Doing "detach 15" (15 == SIGTERM) doesn't work, because detach is a prefix command and doesn't recognize the sub-command 15. Doing "detach inferiors 15" doesn't work because it expects a list of inferior id to detach. Therefore, I don't think there's a way of invoking detach_command with a non-NULL args. I also didn't find any documentation related to this feature. I assume that this feature stopped working when detach was made a prefix command, which is in f73adfeb8bae36885e6ea248d12223ab0d5eb9cb (sorry, there's no commit title) from 2006. Given that this feature was broken for such a long time and we haven't heard anything (AFAIK, I did not find any related bug), I think it's safe to remove it, as well as the args parameter to target_detach. If someone wants to re-introduce it, I would suggest rethinking the user interface, and in particular would suggest using signal name instead of numbers. I tried to fix all the impacted code, but I might have forgotten some spots. It shouldn't be hard to fix if that's the case. I also couldn't build-test everything I changed, especially the nto and solaris stuff. gdb/ChangeLog: * target.h (struct target_ops) <to_detach>: Remove args parameter.

This patch constifies add_info and updates all the info commands. The bulk of this patch was written using a script; and then I did a manual pass to fix up the remaining compilation errors. I could not compile every changed file; in particular nto-procfs.c, gnu-nat.c, and darwin-nat-info.c; but I at least tried to check the correctness by inspection. gdb/ChangeLog 2017-11-07 Tom Tromey <tom@tromey.com> * frame.h (info_locals_command, info_args_command): Constify. * auto-load.h (auto_load_info_scripts): Constify. * inferior.h (registers_info): Constify. * copying.c: Rebuild. * copying.awk: Constify generated commands. * auto-load.c (auto_load_info_scripts) (info_auto_load_gdb_scripts): Constify. * cli/cli-decode.c (struct cmd_list_element): Take a cmd_const_cfunc_ftype. * command.h (add_info): Take a cmd_const_cfunc_ftype. * tui/tui-win.c (tui_all_windows_info): Constify. * python/py-auto-load.c (info_auto_load_python_scripts): Constify. * cli/cli-cmds.c (show_command): Remove non-const overload. * tracepoint.c (info_tvariables_command, info_scope_command): Constify.

2017-11-07Constify add_comTom Tromey1-40/+22
This changes add_com to take a cmd_const_cfunc_ftype, and then fixes up all the command implementations. In most cases this is trivial. In a couple of places I had to again introduce a temporary non-const overload.

2017-11-07Make strip_bg_char return a unique_xmalloc_ptrTom Tromey1-59/+25
This changes strip_bg_char to return a unique_xmalloc_ptr and removes several cleanups. gdb/ChangeLog 2017-11-07 Tom Tromey <tom@tromey.com> * infcmd.c (strip_bg_char): Return gdb::unique_xmalloc_ptr.

2017-11-04Introduce gdb_breakpoint_upTom Tromey1-1/+1
This introduces gdb_breakpoint_up, a unique_ptr typedef that owns a breakpoint. It then changes set_momentary_breakpoint to return a gdb_breakpoint_up and fixes up the fallout. This then allows the removal of make_cleanup_delete_breakpoint. Once breakpoints are fully C++-ified, this typedef can be removed in favor of a plain std::unique_ptr. gdb/ChangeLog 2017-11-04 Tom Tromey <tom@tromey.com> * breakpoint.c (set_momentary_breakpoint): Return breakpoint_up. (until_break_command): Update. (new_until_break_fsm): Change argument types to breakpoint_up. (set_momentary_breakpoint_at_pc): Return breakpoint_up.
