change probes to be program-space-independent This changes the probes to be independent of the program space. After this, when a probe's address is needed, it is determined by applying offsets at the point of use. This introduces a bound_probe object, similar to bound minimal symbols. Objects of this type are used when it's necessary to pass a probe and its corresponding objfile. This removes the backlink from probe to objfile, which was primarily used to fetch the architecture to use. This adds a get_probe_address function which calls a probe method to compute the probe's relocated address. Similarly, it adds an objfile parameter to the semaphore methods so they can do the relocation properly as well. 2014-03-03 Tom Tromey <tromey@redhat.com> * break-catch-throw.c (fetch_probe_arguments): Use bound probes. * breakpoint.c (create_longjmp_master_breakpoint): Use get_probe_address.

Convert tid_range_parser and get_number_or_range to classes This converts tid_range_parser and get_number_or_range to be classes. The various tid_range_parser_* and get_number_or_range_* functions become methods on the respective classes. Then it updates the users to follow. The rationale for the change is that this provides better encapsulation. For example, this forced me to think of a better interface between tid_range_parser and get_number_or_range, since the former peeked into the latter's internals a bit too much. That ended up resulting mostly in these two not-just-straight-1-1 changes: void -tid_range_parser_skip (struct tid_range_parser *parser) +tid_range_parser::skip_range () { ... - tid_range_parser_init (parser, parser->range_parser.end_ptr, - parser->default_inferior); + m_range_parser.skip_range (); + init (m_range_parser.string (), m_default_inferior); } and: /* If we successfully parsed a thread number or finished parsing a thread range, switch back to assuming the next TID is inferior-qualified. */ - if (parser->range_parser.end_ptr == NULL - || parser->range_parser.string == parser->range_parser.end_ptr) + if (!m_range_parser.in_range ()) { For the same reason (encapsulation), this moves the enum tid_range_state definition to within the tid_parser class's scope, since that is private implementation detail. While at it, switch to use "bool" for booleans. gdb/ChangeLog: 2016-10-13 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * tid-parse.h (tid_range_parser): New class.

Put single-step breakpoints on the bp_location chain This patch makes single-step breakpoints "real" breakpoints on the global location list. There are several benefits to this: - It removes the currently limitation that only 2 single-step breakpoints can be inserted. See an example here of a discussion around a case that wants more than 2, possibly unbounded: https://sourceware.org/ml/gdb-patches/2014-03/msg00663.html - makes software single-step work on read-only code regions. The logic to convert a software breakpoint to a hardware breakpoint if the memory map says the breakpoint address is in read only memory is in insert_bp_location. Because software single-step breakpoints bypass all that go and straight to target_insert_breakpoint, we can't software single-step over read only memory. This patch removes that limitation, and adds a test that makes sure that works, by forcing a code region to read-only with "mem LOW HIGH ro" and then stepping through that. - Fixes PR breakpoints/9649 This is an assertion failure in insert_single_step_breakpoint in breakpoint.c, because we may leave stale single-step breakpoints behind on error. The tests for stepping through read-only regions exercise the root cause of the bug, which is that we leave single-step breakpoints behind if we fail to insert any single-step breakpoint. Deleting the single-step breakpoints in resume_cleanups, delete_just_stopped_threads_infrun_breakpoints, and fetch_inferior_event fixes this. Without that, we'd no longer hit the assertion, as that code is deleted, but we'd instead run into errors/warnings trying to insert/remove the stale breakpoints on next resume. - Paves the way to have multiple threads software single-stepping at the same time, leaving update_global_location_list to worry about duplicate locations. - Makes the moribund location machinery aware of software single-step breakpoints, paving the way to enable software single-step on non-stop, instead of forcing serialized displaced stepping for all single steps. - It's generaly cleaner. We no longer have to play games with single-step breakpoints inserted at the same address as regular breakpoints, like we recently had to do for 7.8.

/* Address space at which the breakpoint was placed. */
struct address_space *placed_address_space;
Avoid software breakpoint's instruction shadow inconsistency This change: commit b775012e845380ed4c7421a1b87caf7bfae39f5f Author: Luis Machado <luisgpm@br.ibm.com> Date: Fri Feb 24 15:10:59 2012 +0000 2012-02-24 Luis Machado <lgustavo@codesourcery.com> * remote.c (remote_supports_cond_breakpoints): New forward declaration. [...] changed the way breakpoints are inserted and removed such that `insert_bp_location' can now be called with the breakpoint being handled already in place, while previously the call was only ever made for breakpoints that have not been put in place. This in turn caused an issue for software breakpoints and targets for which a breakpoint's `placed_address' may not be the same as the original requested address. The issue is `insert_bp_location' overwrites the previously adjusted value in `placed_address' with the original address, that is only replaced back with the correct adjusted address later on when `gdbarch_breakpoint_from_pc' is called. Meanwhile there's a window where the value in `placed_address' does not correspond to data stored in `shadow_contents', leading to incorrect instruction bytes being supplied when `one_breakpoint_xfer_memory' is called to supply the instruction overlaid by the breakpoint. And this is exactly what happens on the MIPS target with software breakpoints placed in microMIPS code. In this case not only `placed_address' is not the original address because of the ISA bit, but `mips_breakpoint_from_pc' has to read the original instruction to determine which one of the two software breakpoint instruction encodings to choose as well. The 16-bit encoding is used to replace 16-bit instructions and similarly the 32-bit one is used with 32-bit instructions, to satisfy branch delay slot size requirements. The mismatch between `placed_address' and the address data in `shadow_contents' has been obtained from leads to the wrong encoding being used in some cases, which in the case of a 32-bit software breakpoint instruction replacing a 16-bit instruction causes corruption to the adjacent following instruction and leads the debug session astray if execution reaches there e.g. with a jump. To address this problem I made the change below, that adds a `reqstd_address' field to `struct bp_target_info' and leaves `placed_address' unchanged once it has been set. This ensures data in `shadow_contents' is always consistent with `placed_address'. This approach also has this good side effect that all the places that examine the breakpoint's address see a consistent value, either `reqstd_address' or `placed_address', as required. Currently some places see either the original or the adjusted address in `placed_address', depending on whether they have been called before `gdbarch_remote_breakpoint_from_pc' or afterwards. This is in particular true for subsequent calls to `gdbarch_remote_breakpoint_from_pc' itself, e.g. from `one_breakpoint_xfer_memory'. This is also important for places like `find_single_step_breakpoint' where a breakpoint's address is compared to the raw value of $pc. * breakpoint.h (bp_target_info): Add `reqstd_address' member, update comments. * breakpoint.c (one_breakpoint_xfer_memory): Use `reqstd_address' for the breakpoint's address.

Avoid software breakpoint's instruction shadow inconsistency This change: commit b775012e845380ed4c7421a1b87caf7bfae39f5f Author: Luis Machado <luisgpm@br.ibm.com> Date: Fri Feb 24 15:10:59 2012 +0000 2012-02-24 Luis Machado <lgustavo@codesourcery.com> * remote.c (remote_supports_cond_breakpoints): New forward declaration. [...] changed the way breakpoints are inserted and removed such that `insert_bp_location' can now be called with the breakpoint being handled already in place, while previously the call was only ever made for breakpoints that have not been put in place. This in turn caused an issue for software breakpoints and targets for which a breakpoint's `placed_address' may not be the same as the original requested address. The issue is `insert_bp_location' overwrites the previously adjusted value in `placed_address' with the original address, that is only replaced back with the correct adjusted address later on when `gdbarch_breakpoint_from_pc' is called. Meanwhile there's a window where the value in `placed_address' does not correspond to data stored in `shadow_contents', leading to incorrect instruction bytes being supplied when `one_breakpoint_xfer_memory' is called to supply the instruction overlaid by the breakpoint. And this is exactly what happens on the MIPS target with software breakpoints placed in microMIPS code. In this case not only `placed_address' is not the original address because of the ISA bit, but `mips_breakpoint_from_pc' has to read the original instruction to determine which one of the two software breakpoint instruction encodings to choose as well. The 16-bit encoding is used to replace 16-bit instructions and similarly the 32-bit one is used with 32-bit instructions, to satisfy branch delay slot size requirements. The mismatch between `placed_address' and the address data in `shadow_contents' has been obtained from leads to the wrong encoding being used in some cases, which in the case of a 32-bit software breakpoint instruction replacing a 16-bit instruction causes corruption to the adjacent following instruction and leads the debug session astray if execution reaches there e.g. with a jump. To address this problem I made the change below, that adds a `reqstd_address' field to `struct bp_target_info' and leaves `placed_address' unchanged once it has been set. This ensures data in `shadow_contents' is always consistent with `placed_address'. This approach also has this good side effect that all the places that examine the breakpoint's address see a consistent value, either `reqstd_address' or `placed_address', as required. Currently some places see either the original or the adjusted address in `placed_address', depending on whether they have been called before `gdbarch_remote_breakpoint_from_pc' or afterwards. This is in particular true for subsequent calls to `gdbarch_remote_breakpoint_from_pc' itself, e.g. from `one_breakpoint_xfer_memory'. This is also important for places like `find_single_step_breakpoint' where a breakpoint's address is compared to the raw value of $pc. * breakpoint.h (bp_target_info): Add `reqstd_address' member, update comments. * breakpoint.c (one_breakpoint_xfer_memory): Use `reqstd_address' for the breakpoint's address.

/* GDB maintains two types of information about each breakpoint (or
watchpoint, or other related event). The first type corresponds
to struct breakpoint; this is a relatively high-level structure
which contains the source location(s), stopping conditions, user
commands to execute when the breakpoint is hit, and so forth.
The second type of information corresponds to struct bp_location.
Each breakpoint has one or (eventually) more locations associated
with it, which represent target-specific and machine-specific
mechanisms for stopping the program. For instance, a watchpoint
expression may require multiple hardware watchpoints in order to
catch all changes in the value of the expression being watched. */

'struct expression *' -> gdb::unique_xmalloc_ptr<expression> This patch makes parse_expression and friends return a unique_ptr instead of raw pointer [1]: typedef gdb::unique_malloc_ptr<expression> expression_up; and then adjusts the codebase throughout to stop using cleanups to manage lifetime of expression pointers. Whenever I found a structure owning an expression pointer, I made it store a unique_ptr instead of a raw pointer, which then requires using new/delete of the holding structure, instead of XNEW/xfree. [1] - I'd like to set the rule that types named with an "_up" suffix are unique_ptr typedefs. Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply because we still use xmalloc instead of new to allocate expression objects. Once that's changed, all we need to do is change the expression_up typedef and the smart pointer will then call delete instead of xfree. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_read_renaming_var_value): Use expression_up.

Explicit locations: use new location API This patch converts the code base to use the new struct event_location API being introduced. This patch preserves the current functionality and adds no new features. The "big picture" API usage introduced by this patch may be illustrated with a simple exmaple. Where previously developers would write: void my_command (char *arg, int from_tty) { create_breakpoint (..., arg, ...); ... } one now uses: void my_command (char *arg, int from_tty) { struct event_locaiton *location; struct cleanup *back_to; location = string_to_event_locaiton (&arg, ...); back_to = make_cleanup_delete_event_location (location); create_breakpoint (..., location, ...); do_cleanups (back_to); } Linespec-decoding functions (now called location-decoding) such as decode_line_full no longer skip argument pointers over processed input. That functionality has been moved into string_to_event_location as demonstrated above. gdb/ChangeLog * ax-gdb.c: Include location.h.

Limit breakpoint re-set to the current program space Currently, we always re-set all locations of all breakpoints. This commit makes us re-set only locations of the current program space. If we loaded symbols to a program space (e.g., "file" command or some shared library was loaded), GDB must run through all breakpoints and determine if any new locations need to be added to the breakpoint. However, there's no reason to recreate locations for _other_ program spaces, as those haven't changed. Similarly, when we create a new inferior, through e.g., a fork, GDB must run through all breakpoints and determine if any new locations need to be added to the breakpoint. There's no reason to destroy the locations of the parent inferior and other inferiors. We know those won't change. In addition to being inneficient, resetting breakpoints of inferiors that are currently running is problematic, because: - some targets can't read memory while the inferior is running. - the inferior might exit while we're re-setting its breakpoints, which may confuse prologue skipping. I went through all the places where we call breakpoint_re_set, and it seems to me that all can be changed to only re-set locations of the current program space. The patch that reversed threads order in "info threads" etc. happened to make gdb.threads/fork-plus-thread.exp expose this problem when testing on x86/-m32. The problem was latent and masked out by chance by the code-cache: https://sourceware.org/ml/gdb-patches/2016-01/msg00213.html Tested on x86-64 F20, native (-m64/-m32) and extended-remote gdbserver.

Explicit locations: use new location API This patch converts the code base to use the new struct event_location API being introduced. This patch preserves the current functionality and adds no new features. The "big picture" API usage introduced by this patch may be illustrated with a simple exmaple. Where previously developers would write: void my_command (char *arg, int from_tty) { create_breakpoint (..., arg, ...); ... } one now uses: void my_command (char *arg, int from_tty) { struct event_locaiton *location; struct cleanup *back_to; location = string_to_event_locaiton (&arg, ...); back_to = make_cleanup_delete_event_location (location); create_breakpoint (..., location, ...); do_cleanups (back_to); } Linespec-decoding functions (now called location-decoding) such as decode_line_full no longer skip argument pointers over processed input. That functionality has been moved into string_to_event_location as demonstrated above. gdb/ChangeLog * ax-gdb.c: Include location.h.

Limit breakpoint re-set to the current program space Currently, we always re-set all locations of all breakpoints. This commit makes us re-set only locations of the current program space. If we loaded symbols to a program space (e.g., "file" command or some shared library was loaded), GDB must run through all breakpoints and determine if any new locations need to be added to the breakpoint. However, there's no reason to recreate locations for _other_ program spaces, as those haven't changed. Similarly, when we create a new inferior, through e.g., a fork, GDB must run through all breakpoints and determine if any new locations need to be added to the breakpoint. There's no reason to destroy the locations of the parent inferior and other inferiors. We know those won't change. In addition to being inneficient, resetting breakpoints of inferiors that are currently running is problematic, because: - some targets can't read memory while the inferior is running. - the inferior might exit while we're re-setting its breakpoints, which may confuse prologue skipping. I went through all the places where we call breakpoint_re_set, and it seems to me that all can be changed to only re-set locations of the current program space. The patch that reversed threads order in "info threads" etc. happened to make gdb.threads/fork-plus-thread.exp expose this problem when testing on x86/-m32. The problem was latent and masked out by chance by the code-cache: https://sourceware.org/ml/gdb-patches/2016-01/msg00213.html Tested on x86-64 F20, native (-m64/-m32) and extended-remote gdbserver.

Explicit locations: use new location API This patch converts the code base to use the new struct event_location API being introduced. This patch preserves the current functionality and adds no new features. The "big picture" API usage introduced by this patch may be illustrated with a simple exmaple. Where previously developers would write: void my_command (char *arg, int from_tty) { create_breakpoint (..., arg, ...); ... } one now uses: void my_command (char *arg, int from_tty) { struct event_locaiton *location; struct cleanup *back_to; location = string_to_event_locaiton (&arg, ...); back_to = make_cleanup_delete_event_location (location); create_breakpoint (..., location, ...); do_cleanups (back_to); } Linespec-decoding functions (now called location-decoding) such as decode_line_full no longer skip argument pointers over processed input. That functionality has been moved into string_to_event_location as demonstrated above. gdb/ChangeLog * ax-gdb.c: Include location.h.

struct breakpoint
{
C++ify breakpoint class hierarchy (destructors only) Breakpoints are currently in a limbo state between C and C++. There is a pseudo class hierarchy implemented using struct fields. Taking watchpoint as an example: struct watchpoint { /* The base class. */ struct breakpoint base; ... } and it is instantianted with "new watchpoint ()". When destroyed, a destructor is first invoked through the breakpoint_ops, and then the memory is freed by calling delete through a pointer to breakpoint. Address sanitizer complains about this, for example, because we new and delete the same memory using different types. This patch takes the logical step of making breakpoint subclasses extend the breakpoint class for real, and converts their destructors to actual C++ destructors.

'struct expression *' -> gdb::unique_xmalloc_ptr<expression> This patch makes parse_expression and friends return a unique_ptr instead of raw pointer [1]: typedef gdb::unique_malloc_ptr<expression> expression_up; and then adjusts the codebase throughout to stop using cleanups to manage lifetime of expression pointers. Whenever I found a structure owning an expression pointer, I made it store a unique_ptr instead of a raw pointer, which then requires using new/delete of the holding structure, instead of XNEW/xfree. [1] - I'd like to set the rule that types named with an "_up" suffix are unique_ptr typedefs. Note I used gdb::unique_xmalloc_ptr instead of gdb::unique_ptr, simply because we still use xmalloc instead of new to allocate expression objects. Once that's changed, all we need to do is change the expression_up typedef and the smart pointer will then call delete instead of xfree. gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_read_renaming_var_value): Use expression_up.

Fix PR12526: -location watchpoints for bitfield arguments PR 12526 reports that -location watchpoints against bitfield arguments trigger false positives when bits around the bitfield, but not the bitfield itself, are modified. This happens because -location watchpoints naturally operate at the byte level, not at the bit level. When the address of a bitfield lvalue is taken, information about the bitfield (i.e. its offset and size) is lost in the process. This information must first be retained throughout the lifetime of the -location watchpoint. This patch achieves this by adding two new fields to the watchpoint struct: val_bitpos and val_bitsize. These fields are set when a watchpoint is first defined in watch_command_1. They are both equal to zero if the watchpoint is not a -location watchpoint or if the argument is not a bitfield. Then these bitfield parameters are used inside update_watchpoint and watchpoint_check to extract the actual value of the bitfield from the watchpoint address, with the help of a local helper function extract_bitfield_from_watchpoint_value. Finally when creating a HW breakpoint pointing to a bitfield, we optimize the address and length of the breakpoint. By skipping over the bytes that don't cover the bitfield, this step reduces the frequency at which a read watchpoint for the bitfield is triggered.

/* This bpstat_what stuff tells wait_for_inferior what to do with a

The enum values order defines priority-like order of the actions.
Once you've decided that some action is appropriate, you'll never
go back and decide something of a lower priority is better. Each
of these actions is mutually exclusive with the others. That
means, that if you find yourself adding a new action class here and
wanting to tell GDB that you have two simultaneous actions to
handle, something is wrong, and you probably don't actually need a
new action type.
Note that a step resume breakpoint overrides another breakpoint of

Replace "struct continuation" mechanism by something more extensible This adds an object oriented replacement for the "struct continuation" mechanism, and converts the stepping commands (step, next, stepi, nexti) and the "finish" commands to use it. It adds a new thread "class" (struct thread_fsm) that contains the necessary info and callbacks to manage the state machine of a thread's execution command. This allows getting rid of some hacks. E.g., in fetch_inferior_event and normal_stop we no longer need to know whether a thread is doing a multi-step (e.g., step N). This effectively makes the intermediate_continuations unused -- they'll be garbage collected in a separate patch. (They were never a proper abstraction, IMO. See how fetch_inferior_event needs to check step_multi before knowing whether to call INF_EXEC_CONTINUE or INF_EXEC_COMPLETE.) The target async vs !async uiout hacks in mi_on_normal_stop go away too. print_stop_event is no longer called from normal_stop. Instead it is now called from within each interpreter's normal_stop observer. This clears the path to make each interpreter print a stop event the way it sees fit. Currently we have some hacks in common code to differenciate CLI vs TUI vs MI around this area. The "finish" command's FSM class stores the return value plus that value's position in the value history, so that those can be printed to both MI and CLI's streams. This fixes the CLI "finish" command when run from MI -- it now also includes the function's return value in the CLI stream: (gdb) ~"callee3 (strarg=0x400730 \"A string argument.\") at src/gdb/testsuite/gdb.mi/basics.c:35\n" ~"35\t}\n" +~"Value returned is $1 = 0\n" *stopped,reason="function-finished",frame=...,gdb-result-var="$1",return-value="0",thread-id="1",stopped-threads="all",core="0" -FAIL: gdb.mi/mi-cli.exp: CLI finish: check CLI output +PASS: gdb.mi/mi-cli.exp: CLI finish: check CLI output gdb/ChangeLog: 2015-09-09 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_OBS): Add thread-fsm.o. * breakpoint.c (handle_jit_event): Print debug output.

Teach GDB about targets that can tell whether a trap is a breakpoint event The moribund locations heuristics are problematic. This patch teaches GDB about targets that can reliably tell whether a trap was caused by a software or hardware breakpoint, and thus don't need moribund locations, thus bypassing all the problems that mechanism has. The non-stop-fair-events.exp test is frequently failing currently. E.g., see https://sourceware.org/ml/gdb-testers/2015-q1/msg03148.html. The root cause is a fundamental problem with moribund locations. For example, the stepped_breakpoint logic added by af48d08f breaks in this case (which is what happens with that test): - Step thread A, no breakpoint is set at PC. - The kernel doesn't schedule thread A yet. - Insert breakpoint at A's PC, for some reason (e.g., a step-resume breakpoint for thread B). - Kernel finally schedules thread A. - thread A's stepped_breakpoint flag is not set, even though it now stepped a breakpoint instruction. - adjust_pc_after_break gets the PC wrong, because PC == PREV_PC, but stepped_breakpoint is not set. We needed the stepped_breakpoint logic to workaround moribund locations, because otherwise adjust_pc_after_break could apply an adjustment when it shouldn't just because there _used_ to be a breakpoint at PC (a moribund breakpoint location). For example, on x86, that's wrong if the thread really hasn't executed an int3, but instead executed some other 1-byte long instruction. Getting the PC adjustment wrong of course leads to the inferior executing the wrong instruction. Other problems with moribund locations are: - if a true SIGTRAP happens to be raised when the program is executing the PC that used to have a breakpoint, GDB will assume that is a trap for a breakpoint that has recently been removed, and thus we miss reporting the random signal to the user. - to minimize that, we get rid of moribund location after a while. That while is defined as just a certain number of events being processed. That number of events sometimes passes by before a delayed breakpoint is processed, and GDB confuses the trap for a random signal, thus reporting the random trap. Once the user resumes the thread, the program crashes because the PC was not adjusted... The fix for all this is to bite the bullet and get rid of heuristics and instead rely on the target knowing accurately what caused the SIGTRAP. The target/kernel/stub is in the best position to know what that, because it can e.g. consult priviledged CPU flags GDB has no access to, or by knowing which exception vector entry was called when the instruction trapped, etc. Most debug APIs I've seen to date report breakpoint hits as a distinct event in some fashion. For example, on the Linux kernel, whether a breakpoint was executed is exposed to userspace in the si_code field of the SIGTRAP's siginfo. On Windows, the debug API reports a EXCEPTION_BREAKPOINT exception code. We needed to keep around deleted breakpoints in an on-the-side list (the moribund locations) for two main reasons: - Know that a SIGTRAP actually is a delayed event for a hit of a breakpoint that was removed before the event was processed, and thus should not be reported as a random signal. - So we still do the decr_pc_after_break adjustment in that case, so that the thread is resumed at the correct address. In the new model, if GDB processes an event the target tells is a breakpoint trap, and GDB doesn't find the corresponding breakpoint in its breakpoint tables, it means that event is a delayed event for a breakpoint that has since been removed, and thus the event should be ignored. For the decr_pc_after_after issue, it ends up being much simpler that on targets that can reliably tell whether a breakpoint trapped, for the breakpoint trap to present the PC already adjusted. Proper multi-threading support already implies that targets needs to be doing decr_pc_after_break adjustment themselves, otherwise for example, in all-stop if two threads hit a breakpoint simultaneously, and the user does "info threads", he'll see the non-event thread that hit the breakpoint stopped at the wrong PC. This way (target adjusts) also ends up eliminating the need for some awkward re-incrementing of the PC in the record-full and Linux targets that we do today, and the need for the target_decr_pc_after_break hook. If the target always adjusts, then there's a case where GDB needs to re-increment the PC. Say, on x86, an "int3" instruction that was explicitly written in the program traps. In this case, GDB should report a random SIGTRAP signal to the user, with the PC pointing at the instruction past the int3, just like if GDB was not debugging the program. The user may well decide to pass the SIGTRAP to the program because the program being debugged has a SIGTRAP handler that handles its own breakpoints, and expects the PC to be unadjusted. Tested on x86-64 Fedora 20. gdb/ChangeLog: 2015-03-04 Pedro Alves <palves@redhat.com> * breakpoint.c (need_moribund_for_location_type): New function.

Add comments. (handle_signal_stop): If nothing explains a signal, and the target tells us the stop was caused by a software breakpoint, check if there's a breakpoint instruction in the memory. If so, adjust the PC before presenting the stop to the user. Otherwise, ignore the trap. If nothing explains a signal, and the target tells us the stop was caused by a hardware breakpoint, ignore the trap. * target.h (struct target_ops) <to_stopped_by_sw_breakpoint, to_supports_stopped_by_sw_breakpoint, to_stopped_by_hw_breakpoint, to_supports_stopped_by_hw_breakpoint>: New fields. (target_stopped_by_sw_breakpoint) (target_supports_stopped_by_sw_breakpoint) (target_stopped_by_hw_breakpoint) (target_supports_stopped_by_hw_breakpoint): Define. * target-delegates.c: Regenerate.

Don't displaced step when there's a breakpoint in the scratch pad range Assuming displaced stepping is enabled, and a breakpoint is set in the memory region of the scratch pad, things break. One of two cases can happen: #1 - The breakpoint wasn't inserted yet (all threads were stopped), so after setting up the displaced stepping scratch pad with the adjusted copy of the instruction we're trying to single-step, we insert the breakpoint, which corrupts the scratch pad, and the inferior executes the wrong instruction. (Example below.) This is clearly unacceptable. #2 - The breakpoint was already inserted, so setting up the displaced stepping scratch pad overwrites the breakpoint. This is OK in the sense that we already assume that no thread is going to executes the code in the scratch pad range (after initial startup) anyway. This commit addresses both cases by simply punting on displaced stepping if we have a breakpoint in the scratch pad range. The #1 case above explains a few regressions exposed by the AS/NS series on x86: Running ./gdb.dwarf2/callframecfa.exp ...

linux-nat.c: better starvation avoidance, handle non-stop mode too Running the testsuite with a series that reimplements user-visible all-stop behavior on top of a target running in non-stop mode revealed problems related to event starvation avoidance. For example, I see gdb.threads/signal-while-stepping-over-bp-other-thread.exp failing. What happens is that GDB core never gets to see the signal event. It ends up processing the events for the same threads over an over, because Linux's waitpid(-1, ...) returns that first task in the task list that has an event, starving threads on the tail of the task list. So I wrote a non-stop mode test originally inspired by signal-while-stepping-over-bp-other-thread.exp, to stress this independently of all-stop on top of non-stop. Fixing it required the changes described below. The test will be added in a following commit. 1) linux-nat.c has code in place that picks an event LWP at random out of all that have had events. This is because on the kernel side, "waitpid(-1, ...)" just walks the task list linearly looking for the first that had an event. But, this code is currently only used in all-stop mode. So with a multi-threaded program that has multiple events triggering debug events in parallel, GDB ends up starving some threads. To make the event randomization work in non-stop mode too, the patch makes us pull out all the already pending events on the kernel side, with waitpid, before deciding which LWP to report to the core. There's some code in linux_wait that takes care of leaving events pending if they were for LWPs the caller is not interested in. The patch moves that to linux_nat_filter_event, so that we only have one place that leaves events pending. With that in place, conceptually, the flow is simpler and more normalized: #1 - walk the LWP list looking for an LWP with a pending event to report. #2 - if no pending event, pull events out of the kernel, and store them in the LWP structures as pending. #3- goto #1. 2) Then, currently the event randomization code only considers SIGTRAP (or trap-like) events. That means that if e.g., have have multiple threads stepping in parallel that hit a breakpoint that needs stepping over, and one gets a signal, the signal may end up never getting processed, because GDB will always be giving priority to the SIGTRAPs. The patch fixes this by making the randomization code consider all kinds of pending events. 3) If multiple threads hit a breakpoint, we report one of those, and "cancel" the others. Cancelling means decrementing the PC, and discarding the event. If the next time the LWP is resumed the breakpoint is still installed, the LWP should hit it again, and we'll report the hit then. The problem I found is that this delays threads from advancing too much, with the kernel potentially ending up scheduling the same threads over and over, and others not advancing. So the patch switches away from cancelling the breakpoints, and instead remembering that the LWP had stopped for a breakpoint. If on resume the breakpoint is still installed, we report it. If it's no longer installed, we discard the pending event then. This is actually how GDBserver used to handle this before d50171e4 (Teach linux gdbserver to step-over-breakpoints), but with the difference that back then we'd delay adjusting the PC until resuming, which made it so that "info threads" could wrongly see threads with unadjusted PCs. gdb/ 2015-01-09 Pedro Alves <palves@redhat.com> * breakpoint.c (hardware_breakpoint_inserted_here_p): New function. * breakpoint.h (hardware_breakpoint_inserted_here_p): New declaration. * linux-nat.c (linux_nat_status_is_event): Move higher up in file.

Fix for even more missed events; eliminate thread-hop code. Even with deferred_step_ptid out of the way, GDB can still lose watchpoints. If a watchpoint triggers and the PC points to an address where a thread-specific breakpoint for another thread is set, the thread-hop code triggers, and we lose the watchpoint: if (ecs->event_thread->suspend.stop_signal == GDB_SIGNAL_TRAP) { int thread_hop_needed = 0; struct address_space *aspace = get_regcache_aspace (get_thread_regcache (ecs->ptid)); /* Check if a regular breakpoint has been hit before checking for a potential single step breakpoint. Otherwise, GDB will not see this breakpoint hit when stepping onto breakpoints. */ if (regular_breakpoint_inserted_here_p (aspace, stop_pc)) { if (!breakpoint_thread_match (aspace, stop_pc, ecs->ptid)) thread_hop_needed = 1; ^^^^^^^^^^^^^^^^^^^^^ } And on software single-step targets, even without a thread-specific breakpoint in the way, here in the thread-hop code: else if (singlestep_breakpoints_inserted_p) { ... if (!ptid_equal (singlestep_ptid, ecs->ptid) && in_thread_list (singlestep_ptid)) { /* If the PC of the thread we were trying to single-step has changed, discard this event (which we were going to ignore anyway), and pretend we saw that thread trap. This prevents us continuously moving the single-step breakpoint forward, one instruction at a time. If the PC has changed, then the thread we were trying to single-step has trapped or been signalled, but the event has not been reported to GDB yet. There might be some cases where this loses signal information, if a signal has arrived at exactly the same time that the PC changed, but this is the best we can do with the information available. Perhaps we should arrange to report all events for all threads when they stop, or to re-poll the remote looking for this particular thread (i.e. temporarily enable schedlock). */ CORE_ADDR new_singlestep_pc = regcache_read_pc (get_thread_regcache (singlestep_ptid)); if (new_singlestep_pc != singlestep_pc) { enum gdb_signal stop_signal; if (debug_infrun) fprintf_unfiltered (gdb_stdlog, "infrun: unexpected thread," " but expected thread advanced also\n"); /* The current context still belongs to singlestep_ptid. Don't swap here, since that's the context we want to use. Just fudge our state and continue. */ stop_signal = ecs->event_thread->suspend.stop_signal; ecs->event_thread->suspend.stop_signal = GDB_SIGNAL_0; ecs->ptid = singlestep_ptid; ecs->event_thread = find_thread_ptid (ecs->ptid); ecs->event_thread->suspend.stop_signal = stop_signal; stop_pc = new_singlestep_pc; } else { if (debug_infrun) fprintf_unfiltered (gdb_stdlog, "infrun: unexpected thread\n"); thread_hop_needed = 1; stepping_past_singlestep_breakpoint = 1; saved_singlestep_ptid = singlestep_ptid; } } } we either end up with thread_hop_needed, ignoring the watchpoint SIGTRAP, or switch to the stepping thread, again ignoring that the SIGTRAP could be for some other event. The new test added by this patch exercises both paths. So the fix is similar to the deferred_step_ptid fix -- defer the thread hop to _after_ the SIGTRAP had a change of passing through the regular bpstat handling. If the wrong thread hits a breakpoint, we'll just end up with BPSTAT_WHAT_SINGLE, and if nothing causes a stop, keep_going starts a step-over. Most of the stepping_past_singlestep_breakpoint mechanism is really not necessary -- setting the thread to step over a breakpoint with thread->trap_expected is sufficient to keep all other threads locked. It's best to still keep the flag in some form though, because when we get to keep_going, the software single-step breakpoint we need to step over is already gone -- an optimization done by a follow up patch will check whether a step-over is still be necessary by looking to see whether the breakpoint is still there, and would find the thread no longer needs a step-over, while we still want it. Special care is still needed to handle the case of PC of the thread we were trying to single-step having changed, like in the old code. We can't just keep_going and re-step it, as in that case we can over-step the thread (if it was already done with the step, but hasn't reported it yet, we'd ask it to step even further). That's now handled in switch_back_to_stepped_thread. As bonus, we're now using a technique that doesn't lose signals, unlike the old code -- we now insert a breakpoint at PC, and resume, which either reports the breakpoint immediately, or any pending signal. Tested on x86_64 Fedora 17, against pristine mainline, and against a branch that implements software single-step on x86. gdb/ 2014-03-20 Pedro Alves <palves@redhat.com> * breakpoint.c (single_step_breakpoint_inserted_here_p): Make extern. * breakpoint.h (single_step_breakpoint_inserted_here_p): Declare. * infrun.c (saved_singlestep_ptid) (stepping_past_singlestep_breakpoint): Delete.

PR breakpoints/7143 - Watchpoint does not trigger when first set Say the program is stopped at a breakpoint, and the user sets a watchpoint. When the program is next resumed, GDB will first step over the breakpoint, as explained in the manual: @value {GDBN} normally ignores breakpoints when it resumes execution, until at least one instruction has been executed. If it it did not do this, you would be unable to proceed past a breakpoint without first disabling the breakpoint. This rule applies whether or not the breakpoint already existed when your program stopped. However, GDB currently also removes watchpoints, catchpoints, etc., and that means that the first instruction off the breakpoint does not trigger the watchpoint, catchpoint, etc. testsuite/gdb.base/watchpoint.exp has a kfail for this. The PR proposes installing watchpoints only when stepping over a breakpoint, but that misses catchpoints, etc. A better fix would instead work from the opposite direction -- remove only real breakpoints, leaving all other kinds of breakpoints inserted. But, going further, it's really a waste to constantly remove/insert all breakpoints when stepping over a single breakpoint (generating a pair of RSP z/Z packets for each breakpoint), so the fix goes a step further and makes GDB remove _only_ the breakpoint being stepped over, leaving all others installed. This then has the added benefit of reducing breakpoint-related RSP traffic substancialy when there are many breakpoints set. gdb/ 2014-03-20 Pedro Alves <palves@redhat.com> PR breakpoints/7143 * breakpoint.c (should_be_inserted): Don't insert breakpoints that are being stepped over.

Limit breakpoint re-set to the current program space Currently, we always re-set all locations of all breakpoints. This commit makes us re-set only locations of the current program space. If we loaded symbols to a program space (e.g., "file" command or some shared library was loaded), GDB must run through all breakpoints and determine if any new locations need to be added to the breakpoint. However, there's no reason to recreate locations for _other_ program spaces, as those haven't changed. Similarly, when we create a new inferior, through e.g., a fork, GDB must run through all breakpoints and determine if any new locations need to be added to the breakpoint. There's no reason to destroy the locations of the parent inferior and other inferiors. We know those won't change. In addition to being inneficient, resetting breakpoints of inferiors that are currently running is problematic, because: - some targets can't read memory while the inferior is running. - the inferior might exit while we're re-setting its breakpoints, which may confuse prologue skipping. I went through all the places where we call breakpoint_re_set, and it seems to me that all can be changed to only re-set locations of the current program space. The patch that reversed threads order in "info threads" etc. happened to make gdb.threads/fork-plus-thread.exp expose this problem when testing on x86/-m32. The problem was latent and masked out by chance by the code-cache: https://sourceware.org/ml/gdb-patches/2016-01/msg00213.html Tested on x86-64 F20, native (-m64/-m32) and extended-remote gdbserver.

Explicit locations: use new location API This patch converts the code base to use the new struct event_location API being introduced. This patch preserves the current functionality and adds no new features. The "big picture" API usage introduced by this patch may be illustrated with a simple exmaple. Where previously developers would write: void my_command (char *arg, int from_tty) { create_breakpoint (..., arg, ...); ... } one now uses: void my_command (char *arg, int from_tty) { struct event_locaiton *location; struct cleanup *back_to; location = string_to_event_locaiton (&arg, ...); back_to = make_cleanup_delete_event_location (location); create_breakpoint (..., location, ...); do_cleanups (back_to); } Linespec-decoding functions (now called location-decoding) such as decode_line_full no longer skip argument pointers over processed input.

/* Set a breakpoint. This function is shared between CLI and MI functions
for setting a breakpoint at LOCATION.
This function has two major modes of operations, selected by the
PARSE_EXTRA parameter.
If PARSE_EXTRA is zero, LOCATION is just the breakpoint's location,
with condition, thread, and extra string specified by the COND_STRING,
THREAD, and EXTRA_STRING parameters.
If PARSE_EXTRA is non-zero, this function will attempt to extract
the condition, thread, and extra string from EXTRA_STRING, ignoring
the similarly named parameters.
If INTERNAL is non-zero, the breakpoint number will be allocated

Change detach_breakpoints to take a ptid instead of a pid Before this change, detach_breakpoints would take a pid, and then set inferior_ptid to a ptid that it constructs using pid_to_ptid (pid). Unfortunately, this ptid is not necessarily valid. Consider for instance the case of ia64-hpux, where ttrace refuses a register-read operation if the LWP is not provided. This problems shows up when GDB is trying to handle fork events. Assuming GDB is configured to follow the parent, GDB will try to detach from the child. But before doing so, it needs to remove all breakpoints inside that child. On ia64, this involves reading inferior (the child's) memory. And on ia64-hpux, reading memory requires us to read the bsp and bspstore registers, in order to determine where that memory is relative to the value of those registers, and thus to determine which ttrace operation to use in order to fetch that memory (see ia64_hpux_xfer_memory). This patch therefore changes detach_breakpoints to take a ptid instead of a pid, and then updates all callers. One of the consequences of this patch is that it trips an assert on GNU/Linux targets. But this assert appears to have not actual purpose, and is thus removed. gdb/ChangeLog: * breakpoint.h (detach_breakpoints): pid parameter is now a ptid. * breakpoint.c (detach_breakpoints): Change pid parameter into a ptid. Adjust code accordingly. * infrun.c (handle_inferior_event): Delete variable child_pid. Update call to detach_breakpoints to pass the child ptid for fork events. * linux-nat.c (linux_nat_iterate_watchpoint_lwps): Remove assert that inferior_ptid's lwp is zero. (linux_handle_extended_wait): Update call to detach_breakpoints. * inf-ttrace.c (inf_ttrace_follow_fork): Update call to detach_breakpoints.

Associate dummy_frame with ptid This patch is to add ptid into dummy_frame and extend frame_id to dummy_frame_id (which has a ptid field). With this change, GDB uses dummy_frame_id (thread ptid and frame_id) to find the dummy frames. Currently, dummy frames are looked up by frame_id, which isn't accurate in non-stop or multi-process mode. The test case gdb.multi/dummy-frame-restore.exp shows the problem and this patch can fix it. Test dummy-frame-restore.exp makes two inferiors stop at different functions, say, inferior 1 stops at f1 while inferior 2 stops at f2. Set a breakpoint to a function, do the inferior call in two inferiors, and GDB has two dummy frames of the same frame_id. When the inferior call is finished, GDB will look up a dummy frame from its stack/list and restore the inferior's regcache. Two inferiors are finished in different orders, the inferiors' states are restored differently, which is wrong. Running dummy-frame-restore.exp under un-patched GDB, we'll get two fails: FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 2 FAIL: gdb.multi/dummy-frame-restore.exp: inf 2 first: after infcall: bt in inferior 1 With this patch applied, GDB will choose the correct dummy_frame to restore for a given inferior, because ptid is considered when looking up dummy frames.

The intended client of these functions is call_function_by_hand.
The inferior must be stopped, and all breakpoints removed, when
these functions are used.
The need for these functions is that on some targets (e.g., HP-UX),
gdb is unable to unwind through the dummy frame that is pushed as
part of the implementation of a call command. Watchpoints can
cause the inferior to stop in places where this frame is visible,
and that can cause execution control to become very confused.
Note that if a user sets breakpoints in an interactively called
function, the call_disabled watchpoints will have been re-enabled
when the first such breakpoint is reached. However, on targets
that are unable to unwind through the call dummy frame, watches
of stack-based storage may then be deleted, because gdb will
believe that their watched storage is out of scope. (Sigh.) */

[IRIX] eliminate deprecated_insert_raw_breakpoint uses The IRIX support wants to set a breakpoint to be hit when the startup phase is complete, which is where shared libraries have been mapped in. AFAIU, for most IRIX ports, that location is the entry point. For MIPS IRIX however, GDB needs to set a breakpoint earlier, in __dbx_link, as explained by: #ifdef SYS_syssgi /* On mips-irix, we need to stop the inferior early enough during the startup phase in order to be able to load the shared library symbols and insert the breakpoints that are located in these shared libraries. Stopping at the program entry point is not good enough because the -init code is executed before the execution reaches that point. So what we need to do is to insert a breakpoint in the runtime loader (rld), more precisely in __dbx_link(). This procedure is called by rld once all shared libraries have been mapped, but before the -init code is executed. Unfortuantely, this is not straightforward, as rld is not part of the executable we are running, and thus we need the inferior to run until rld itself has been mapped in memory. For this, we trace all syssgi() syscall exit events. Each time we detect such an event, we iterate over each text memory maps, get its associated fd, and scan the symbol table for __dbx_link(). When found, we know that rld has been mapped, and that we can insert the breakpoint at the symbol address. Once the dbx_link() breakpoint has been inserted, the syssgi() notifications are no longer necessary, so they should be canceled. */ proc_trace_syscalls_1 (pi, SYS_syssgi, PR_SYSEXIT, FLAG_SET, 0); #endif The loop in irix_solib_create_inferior_hook then runs until whichever breakpoint is hit first, the one set by solib-irix.c or the one set by procfs.c. Note the comment in disable_break talks about __dbx_init, but I think that's a typo for __dbx_link: - /* Note that it is possible that we have stopped at a location that - is different from the location where we inserted our breakpoint. - On mips-irix, we can actually land in __dbx_init(), so we should - not check the PC against our breakpoint address here. See procfs.c - for more details. */ This looks very much like referring to the loop in irix_solib_create_inferior_hook stopping at __dbx_link instead of at the entry point. What this patch does is convert these deprecated raw breakpoints to standard solib_event breakpoints. When the first solib-event breakpoint is hit, we delete all solib-event breakpoints. We do that in the so_ops->handle_event hook. This allows getting rid of the loop in irix_solib_create_inferior_hook completely, which should allow properly handling signals and other events in the early startup phase, like in SVR4.

[IRIX] eliminate deprecated_insert_raw_breakpoint uses The IRIX support wants to set a breakpoint to be hit when the startup phase is complete, which is where shared libraries have been mapped in. AFAIU, for most IRIX ports, that location is the entry point. For MIPS IRIX however, GDB needs to set a breakpoint earlier, in __dbx_link, as explained by: #ifdef SYS_syssgi /* On mips-irix, we need to stop the inferior early enough during the startup phase in order to be able to load the shared library symbols and insert the breakpoints that are located in these shared libraries. Stopping at the program entry point is not good enough because the -init code is executed before the execution reaches that point. So what we need to do is to insert a breakpoint in the runtime loader (rld), more precisely in __dbx_link().

Put single-step breakpoints on the bp_location chain This patch makes single-step breakpoints "real" breakpoints on the global location list. There are several benefits to this: - It removes the currently limitation that only 2 single-step breakpoints can be inserted. See an example here of a discussion around a case that wants more than 2, possibly unbounded: https://sourceware.org/ml/gdb-patches/2014-03/msg00663.html - makes software single-step work on read-only code regions. The logic to convert a software breakpoint to a hardware breakpoint if the memory map says the breakpoint address is in read only memory is in insert_bp_location. Because software single-step breakpoints bypass all that go and straight to target_insert_breakpoint, we can't software single-step over read only memory. This patch removes that limitation, and adds a test that makes sure that works, by forcing a code region to read-only with "mem LOW HIGH ro" and then stepping through that. - Fixes PR breakpoints/9649 This is an assertion failure in insert_single_step_breakpoint in breakpoint.c, because we may leave stale single-step breakpoints behind on error. The tests for stepping through read-only regions exercise the root cause of the bug, which is that we leave single-step breakpoints behind if we fail to insert any single-step breakpoint. Deleting the single-step breakpoints in resume_cleanups, delete_just_stopped_threads_infrun_breakpoints, and fetch_inferior_event fixes this. Without that, we'd no longer hit the assertion, as that code is deleted, but we'd instead run into errors/warnings trying to insert/remove the stale breakpoints on next resume. - Paves the way to have multiple threads software single-stepping at the same time, leaving update_global_location_list to worry about duplicate locations. - Makes the moribund location machinery aware of software single-step breakpoints, paving the way to enable software single-step on non-stop, instead of forcing serialized displaced stepping for all single steps. - It's generaly cleaner. We no longer have to play games with single-step breakpoints inserted at the same address as regular breakpoints, like we recently had to do for 7.8.

Fix non-stop regressions caused by "breakpoints always-inserted off" changes Commit a25a5a45 (Fix "breakpoint always-inserted off"; remove "breakpoint always-inserted auto") regressed non-stop remote debugging. This was exposed by mi-nsintrall.exp intermittently failing with a spurious SIGTRAP. The problem is that when debugging with "target remote", new threads the target has spawned but have never reported a stop aren't visible to GDB until it explicitly resyncs its thread list with the target's. For example, in a program like this: int main (void) { pthread_t child_thread; pthread_create (&child_thread, NULL, child_function, NULL); return 0; <<<< set breakpoint here } If the user sets a breakpoint at the "return" statement, and runs the program, when that breakpoint hit is reported, GDB is only aware of the main thread. So if we base the decision to remove or insert breakpoints from the target based on whether all the threads we know about are stopped, we'll miss that child_thread is running, and thus we'll remove breakpoints from the target, even through they should still remain inserted, otherwise child_thread will miss them. The break-while-running.exp test actually should also be exposing this thread-list-out-of-synch problem. That test sets a breakpoint while the main thread is stopped, but other threads are running. Because other threads are running, the breakpoint is supposed to be inserted immediately. But, unless something forces a refetch of the thread list, like, e.g., "info threads", GDB won't be aware of the other threads that had been spawned by the main thread, and so won't insert new or old breakpoints in the target. And it turns out that the test is exactly doing an explicit "info threads", masking out the problem... This commit adjust the test to exercise the case of not issuing "info threads". The test then fails without the GDB fix. In the ni-nsintrall.exp case, what happens is that several threads hit the same breakpoint, and when the first thread reports the stop, because GDB wasn't aware other threads exist, all threads known to GDB are found stopped, so GDB removes the breakpoints from the target. The other threads follow up with SIGTRAPs too for that same breakpoint, which has already been removed. For the first few threads, the moribund breakpoints machinery suppresses the SIGTRAPs, but after a few events (precisely '3 * thread_count () + 1' at the time the breakpoint was removed, see update_global_location_list), the moribund breakpoint machinery is no longer aware of the removed breakpoint, and the SIGTRAP is reported as a spurious stop. The fix is naturally then to stop assuming that if no thread in the list is executing, then the target is fully stopped. We can't know that until we fully sync the thread list. Because updating the thread list on every stop would be too much RSP traffic, I chose instead to update it whenever we're about to present a stop to the user. Actually updating the thread list at that point happens to be an item I had added to the local/remote parity wiki page a while ago: Native GNU/Linux debugging adds new threads to the thread list as the program creates them "The [New Thread foo] messages". Remote debugging can't do that, and it's arguable whether we shouldn't even stop native debugging from doing that, as it hinders inferior performance. However, a related issue is that with remote targets (and gdbserver), even after the program stops, the user still needs to do "info threads" to pull an updated thread list. This, should most likely be addressed, so that GDB pulls the list itself, perhaps just before presenting a stop to the user. With that in place, the need to delay "Program received signal FOO" was actually caught by the manythreads.exp test. Without that bit, I was getting: [Thread 0x7ffff7f13700 (LWP 4499) exited] [New Thread 0x7ffff7f0b700 (LWP 4500)] ^C Program received signal SIGINT, Interrupt.

As the number of new threads discovered before and after the "Program received signal" output is unbounded, it's much nicer to defer "Program received signal" until after synching the thread list, thus close to the "switching to thread" output and "current frame/source" info: [Thread 0x7ffff7863700 (LWP 7647) exited] ^C[New Thread 0x7ffff786b700 (LWP 7648)] Program received signal SIGINT, Interrupt.

/* Return true if breakpoints should be inserted now. That'll be the
case if either:

*/
Fix "breakpoint always-inserted off"; remove "breakpoint always-inserted auto" By default, GDB removes all breakpoints from the target when the target stops and the prompt is given back to the user. This is useful in case GDB crashes while the user is interacting, as otherwise, there's a higher chance breakpoints would be left planted on the target. But, as long as any thread is running free, we need to make sure to keep breakpoints inserted, lest a thread misses a breakpoint. With that in mind, in preparation for non-stop mode, we added a "breakpoint always-inserted on" mode. This traded off the extra crash protection for never having threads miss breakpoints, and in addition is more efficient if there's a ton of breakpoints to remove/insert at each user command (e.g., at each "step"). When we added non-stop mode, and for a period, we required users to manually set "always-inserted on" when they enabled non-stop mode, as otherwise GDB removes all breakpoints from the target as soon as any thread stops, which means the other threads still running will miss breakpoints. The test added by this patch exercises this. That soon revealed a nuisance, and so later we added an extra "breakpoint always-inserted auto" mode, that made GDB behave like "always-inserted on" when non-stop was enabled, and "always-inserted off" when non-stop was disabled. "auto" was made the default at the same time. In hindsight, this "auto" setting was unnecessary, and not the ideal solution. Non-stop mode does depends on breakpoints always-inserted mode, but only as long as any thread is running. If no thread is running, no breakpoint can be missed. The same is true for all-stop too. E.g., if, in all-stop mode, and the user does: (gdb) c& (gdb) b foo That breakpoint at "foo" should be inserted immediately, but it currently isn't -- currently it'll end up inserted only if the target happens to trip on some event, and is re-resumed, e.g., an internal breakpoint triggers that doesn't cause a user-visible stop, and so we end up in keep_going calling insert_breakpoints. The test added by this patch also covers this. IOW, no matter whether in non-stop or all-stop, if the target fully stops, we can remove breakpoints. And no matter whether in all-stop or non-stop, if any thread is running in the target, then we need breakpoints to be immediately inserted. And then, if the target has global breakpoints, we need to keep breakpoints even when the target is stopped. So with that in mind, and aiming at reducing all-stop vs non-stop differences for all-stop-on-stop-of-non-stop, this patch fixes "breakpoint always-inserted off" to not remove breakpoints from the target until it fully stops, and then removes the "auto" setting as unnecessary. I propose removing it straight away rather than keeping it as an alias, unless someone complains they have scripts that need it and that can't adjust.

extern struct tracepoint *
Convert tid_range_parser and get_number_or_range to classes This converts tid_range_parser and get_number_or_range to be classes. The various tid_range_parser_* and get_number_or_range_* functions become methods on the respective classes. Then it updates the users to follow. The rationale for the change is that this provides better encapsulation. For example, this forced me to think of a better interface between tid_range_parser and get_number_or_range, since the former peeked into the latter's internals a bit too much. That ended up resulting mostly in these two not-just-straight-1-1 changes: void -tid_range_parser_skip (struct tid_range_parser *parser) +tid_range_parser::skip_range () { ... - tid_range_parser_init (parser, parser->range_parser.end_ptr, - parser->default_inferior); + m_range_parser.skip_range (); + init (m_range_parser.string (), m_default_inferior); } and: /* If we successfully parsed a thread number or finished parsing a thread range, switch back to assuming the next TID is inferior-qualified. */ - if (parser->range_parser.end_ptr == NULL - || parser->range_parser.string == parser->range_parser.end_ptr) + if (!m_range_parser.in_range ()) { For the same reason (encapsulation), this moves the enum tid_range_state definition to within the tid_parser class's scope, since that is private implementation detail.

Fix PR threads/19422 - show which thread caused stop This commit changes GDB like this: - Program received signal SIGINT, Interrupt. + Thread 1 "main" received signal SIGINT, Interrupt. - Breakpoint 1 at 0x40087a: file threads.c, line 87. + Thread 3 "bar" hit Breakpoint 1 at 0x40087a: file threads.c, line 87. ... once the program goes multi-threaded. Until GDB sees a second thread spawn, the output is still the same as before, per the discussion back in 2012: https://www.sourceware.org/ml/gdb/2012-11/msg00010.html This helps non-stop mode, where you can't easily tell which thread hit a breakpoint or received a signal: (gdb) info threads Id Target Id Frame * 1 Thread 0x7ffff7fc1740 (LWP 19362) "main" (running) 2 Thread 0x7ffff7fc0700 (LWP 19366) "foo" (running) 3 Thread 0x7ffff77bf700 (LWP 19367) "bar" (running) (gdb) Program received signal SIGUSR1, User defined signal 1. 0x0000003616a09237 in pthread_join (threadid=140737353877248, thread_return=0x7fffffffd5b8) at pthread_join.c:92 92 lll_wait_tid (pd->tid); (gdb) b threads.c:87 Breakpoint 1 at 0x40087a: file threads.c, line 87. (gdb) Breakpoint 1, thread_function1 (arg=0x1) at threads.c:87 87 usleep (1); /* Loop increment. */ The best the user can do is run "info threads" and try to figure things out. It actually also affects all-stop mode, in case of "handle SIG print nostop": ... Program received signal SIGUSR1, User defined signal 1. Program received signal SIGUSR1, User defined signal 1. Program received signal SIGUSR1, User defined signal 1. Program received signal SIGUSR1, User defined signal 1. ... The above doesn't give any clue that these were different threads getting the SIGUSR1 signal. I initially thought of lowercasing "breakpoint" in "Thread 3 hit Breakpoint 1" but then after trying it I realized that leaving "Breakpoint" uppercase helps the eye quickly find the relevant information. It's also easier to implement not showing anything about threads until the program goes multi-threaded this way. Here's a larger example session in non-stop mode: (gdb) c -a& Continuing.
