Pedro Alves	d9f719f1ad	target factories, target open and multiple instances of targets ... Currently, to open a target, with "target TARGET_NAME", GDB finds the target_ops instance with "TARGET_NAME" as short name, and then calls its target_ops::open virtual method. In reality, there's no actual target/name lookup, a pointer to the target_ops object was associated with the "target TARGET_NAME" command at add_target time (when GDB is initialized), as the command's context. This creates a chicken and egg situation. Consider the case of wanting to open multiple remote connections. We want to be able to have one remote target_ops instance per connection, but, if we're not connected yet, so we don't yet have an instance to call target->open() on... This patch fixes this by separating out common info about a target_ops to a separate structure (shortname, longname, doc), and changing the add_target routine to take a reference to such an object instead of a pointer to a target_ops, and a pointer to a factory function that is responsible to open an instance of the corresponding target when the user types "target TARGET_NAME". -extern void add_target (struct target_ops *); +extern void add_target (const target_info &info, target_open_ftype *func); I.e. this factory function replaces the target_ops::open virtual method. For static/singleton targets, nothing changes, the target_open_ftype function pushes the global target_ops instance on the target stack. At target_close time, the connection is tor down, but the global target_ops object remains live. However, targets that support being open multiple times will make their target_open_ftype routine allocate a new target_ops instance on the heap [e.g., new remote_target()], and push that on the stack. At target_close time, the new object is destroyed (by the target_ops::close virtual method). Both the core target and the remote targets will support being open multiple times (others could/should too, but those were my stopping point), but not in this patch yet. We need to get rid of more globals first before that'd be useful. Native targets are somewhat special, given find_default_run_target & friends. Those routines also expect to return a target_ops pointer, even before we've open the target. However, we'll never need more than one instance of the native target, so we can assume/require that native targets are global/simpletons, and have the backends register a pointer to the native target_ops. Since all native targets inherit inf_child_target, we can centralize that registration. See add_inf_child_target, get_native_target/set_native_target and find_default_run_target. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> * aarch64-fbsd-nat.c (_initialize_aarch64_fbsd_nat): Use add_inf_child_target. * aarch64-linux-nat.c (_initialize_aarch64_linux_nat): Use add_inf_child_target. * aix-thread.c (aix_thread_target_info): New.

Pedro Alves	f6ac5f3d63	Convert struct target_ops to C++ ... 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.

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.

Yao Qi	c8ec2f334c	Class detached_regcache ... jit.c uses the regcache in a slightly different way, the regcache dosen't write through to target, but it has read and write methods. If I apply regcache in record-full.c, it has the similar use pattern. This patch adds a new class detached_regcache, a register buffer, but can be read and written. Since jit.c doesn't want to write registers through to target, it uses regcache as a readonly regcache (because only readonly regcache disconnects from the target), but it adds a hole in regcache (raw_set_cached_value) in order to modify a readonly regcache. This patch fixes this hole completely. regcache inherits detached_regcache, and detached_regcache inherits readable_regcache. The ideal design is that both detached_regcache and readable_regcache inherit reg_buffer, and regcache inherit detached_regcache and regcache_read (virtual inheritance). I concern about the performance overhead of virtual inheritance, so I don't do it in the patch. gdb: 2018-02-21 Yao Qi <yao.qi@linaro.org> * jit.c (struct jit_unwind_private) <regcache>: Change its type to reg_buffer_rw *.

Tom Tromey	981a3fb359	Constify add_prefix_cmd ... This changes add_prefix_cmd to accept a const-taking function as an argument; then fixes up all the callers. In a couple of spots I had to add a non-const overload of a function, because the function is passed to two different command-adding "constructors". These overloads are temporary; once constification is complete they can be removed. This patch also fixes a typo I happened to notice while constifying. Note that this touches a couple of files (gnu-nat.c and go32-nat.c) that I can't build. So, while I made a best-effort there, I am not certain they will still compile.

Pedro Alves	bf46927112	Eliminate catch_errors ... If you want to use catch_errors with a function with parameters, then currently you have to manually write a "capture" struct wrapping the arguments and marshall/unmarshall that. https://sourceware.org/ml/gdb-patches/2017-09/msg00834.html proposed adjusting catch_errors to use gdb::function_view, which would allow passing lambdas with automatic captures. However, it seems like using TRY/CATCH directly instead ends up producing clearer and easier to debug code. This is what this commit does. Note that removing catch_errors exposes further cleanup opportunities around no longer having to follow catch_errors callback type, and also removes a few cleanups. I didn't do anything to save/restore current_uiout because I think that should be the responsibility of the code that changes current_uiout in the first place. (Another approach could be to make catch_errors a variadic template like: template<typename Function, typename... Args> int catch_errors (const char *errstring, return_mask mask, Function &&func, Args... args); and then with: extern void function_with_args (int, int); extern void function_with_no_args (); calls to the above functions would be wrapped like this: catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_args, arg1, arg2); catch_errors ("some error happened", RETURN_MASK_ERROR, function_with_no_args); but I'm thinking that that doesn't improve much if at all either.) gdb/ChangeLog 2017-10-10 Pedro Alves <palves@redhat.com> Tom Tromey <tom@tromey.com> * breakpoint.c (breakpoint_cond_eval): Change return type to bool and reverse logic.

Tom Tromey	223ffa714c	Remove make_cleanup_restore_target_terminal ... This removes make_cleanup_restore_target_terminal and generally C++-ifies target terminal handling. It changes all target_terminal_* functions to be static members of a new target_terminal class and changes the cleanup to be a scoped_* class. make_cleanup_override_quit_handler is also removed in favor of simply using scoped_restore. Note that there are some files in this patch that I could not compile. Considering that some of the rewrites were automated, and that none of these files involed cleanups, I feel that this is relatively safe.

Simon Marchi	873c08142c	record-full: Remove unused function netorder16 ... clang shows this warning: /home/emaisin/src/binutils-gdb/gdb/record-full.c:2344:1: error: unused function 'netorder16' [-Werror,-Wunused-function] netorder16 (uint16_t input) ^ Remove this function, which, AFAIK, has never been used. Note that GCC doesn't warn about this, because the function is marked as inline. According to gcc's man page, it should ideed not warn: -Wunused-function Warn whenever a static function is declared but not defined or a non-inline static function is unused. This warning is enabled by -Wall. So it's probably not a GCC bug that it doesn't find this unused function, but a different definition of "unused". gdb/ChangeLog: * record-full.c (netorder16): Remove.	2017-06-26 16:51:17 +02:00

Tom Tromey	bef155c3e8	Introduce and use gdb::unlinker ... This introduces a new class, gdb::unlinker, that unlinks a file in the destructor. The user of this class has the option to preserve the file instead, by calling the "keep" method. This patch then changes the spots in gdb that use unlink in a cleanup to use this class instead. In one spot I went ahead and removed all the cleanups from the function. This fixes one latent bug -- do_bfd_delete_cleanup could refer to freed memory, by decref'ing the BFD before using its filename. 2017-01-10 Tom Tromey <tom@tromey.com> * record-full.c (record_full_save_cleanups): Remove.

Tom Tromey	192b62ce0b	Use class to manage BFD reference counts ... This introduces a new specialization of gdb::ref_ptr that can be used to manage BFD reference counts. Then it changes most places in gdb to use this new class, rather than explicit reference-counting or cleanups. This patch removes make_cleanup_bfd_unref. If you look you will see a couple of spots using "release" where a use of gdb_bfd_ref_ptr would be cleaner. These will be fixed in the next patch. I think this patch fixes some latent bugs. For example, it seems to me that previously objfpy_add_separate_debug_file leaked a BFD. I'm not 100% certain that the macho_symfile_read_all_oso change is correct.

Yao Qi	cd6c3b4ffc	New gdbarch methods breakpoint_kind_from_pc and sw_breakpoint_from_kind ... This patch adds two gdbarch methods breakpoint_kind_from_pc and sw_breakpoint_from_kind, and uses target_info.placed_size as "kind" of the breakpoint. This patch updates the usages of target_info.placed_size. The "kind" of a breakpoint is determined by gdbarch rather than target, so we have gdbarch method breakpoint_kind_from_pc, and we should set target_info.placed_size out of each implementation of target to_insert_breakpoint. In this way, each target doesn't have to set target_info.placed_size any more. This patch also sets target_info.placed_address before target_insert_breakpoint too, so that target to_insert_breakpoint can use it, see record_full_insert_breakpoint. Before we call target_insert_breakpoint, we set target_info.placed_address and target_info.placed_size like this, CORE_ADDR addr = bl->target_info.reqstd_address; bl->target_info.placed_size = gdbarch_breakpoint_kind_from_pc (bl->gdbarch, &addr); bl->target_info.placed_address = addr; return target_insert_breakpoint (bl->gdbarch, &bl->target_info); target_insert_breakpoint may fail, but it doesn't matter to the "kind" and "placed_address" of a breakpoint.

Pedro Alves	85ad3aaf40	gdb: Coalesce/aggregate (async) vCont packets/actions ... Currently, with "maint set target-non-stop on", that is, when gdb connects with the non-stop/asynchronous variant of the remote protocol, even with "set non-stop off", GDB always sends one vCont packet per thread resumed. This patch makes GDB aggregate and coalesce vCont packets, so we send vCont packets like "vCont;s:p1.1;c" in non-stop mode too. Basically, this is done by: - Adding a new target method target_commit_resume that is called after calling target_resume one or more times. When resuming a batch of threads, we'll only call target_commit_resume once after calling target_resume for all threads. - Making the remote target defer sending the actual vCont packet to target_commit_resume. Special care must be taken to avoid sending a vCont action with a "wildcard" thread-id (all threads of process / all threads) when that would resume threads/processes that should not be resumed. See remote_commit_resume comments for details. Unlike all-stop's remote_resume implementation, this handles the case of too many actions resulting in a too-big vCont packet, by flushing the vCont packet and starting a new one. E.g., imagining that the "c" action in: vCont;s:1;c overflows the packet buffer, we split the actions like: vCont;s:1 vCont;c Tested on x86_64 Fedora 20, with and without "maint set target-non-stop on". Also tested with a hack that makes remote_commit_resume flush the vCont packet after every action appended (which caught a few bugs). gdb/ChangeLog: 2016-10-26 Pedro Alves <palves@redhat.com> * inferior.h (ALL_NON_EXITED_INFERIORS): New macro. * infrun.c (do_target_resume): Call target_commit_resume.

Pedro Alves	01d3dedf60	Fix PR gdb/19187 (process record over a fork causes internal error) ... Right after a fork is detected, we detach breakpoints from the child (detach_breakpoints), which calls into target_remove_breakpoint with inferior_ptid pointing at the child process, but leaves the breakpoint marked inserted (in the parent). The problem is that record-full.c always deletes all knowledge of the breakpoint. Then when we later really delete the breakpoint from the parent, we fail the assertion, since the breakpoint is unexpectedly not found in the record-full.c breakpoint table. The fix is simply to not forget about the breakpoint if we're detaching it from a fork child. gdb/ChangeLog: 2016-08-10 Pedro Alves <palves@redhat.com> PR gdb/19187 * record-full.c (record_full_remove_breakpoint): Don't remove the breakpoint from the record_full_breakpoints VEC if we're detaching the breakpoint from a fork child. gdb/testsuite/ChangeLog: 2016-08-10 Pedro Alves <palves@redhat.com> PR gdb/19187 * gdb.reverse/waitpid-reverse.exp: Add comment and remove setup_kfails.	2016-08-10 23:03:29 +01:00

That is fine to remote target, because Z/z packets are idempotent, but there is a leftover in record_full_breakpoints in record-full target. The flow can be described as below, record_full_breakpoints remote target ----------------------------------------------------------------------- forward execution, continue, in_target_beneath 1 breakpoint inserted insert breakpoints on 0x85f4 in_target_beneath 1 twice program stops, remove breakpoint on 0x85f4 in_target_beneath 1 breakpoint removed reverse execution, continue, in_target_beneath 1 none is requested insert breakpoints on 0x85f4, in_target_beneath 0 program stops, remote breakpoint on 0x85f4, in_target_beneath 0 request to remove, but GDBserver doesn't know now, the question is why breakoint on 0x85f4 is inserted twice? One is the normal breakpoint, and the other is the single step breakpoint. GDB inserts single step breakpoint to do single step. When program stops at 0x85f4, both of them are set on 0x85f4, and GDB deletes single step breakpoint, so in update_global_location_list, this breakpoint location is no longer found, GDB call force_breakpoint_reinsertion to mark it condition_updated, and insert it again. The reason force_breakpoint_reinsertion is called to update the conditions in the target side, because the conditions may be changed. My original fix is to not call force_breakpoint_reinsertion if OLD_LOC->cond is NULL, but it is not correct if another location on the same address has condition, GDB doesn't produce condition for target side, but GDB should do. Then, I change my mind back to make record-full handling breakpoint idempotent, to align with remote target. Before insert a new entry into record_full_breakpoints, look for existing one on the same address first. I also add an assert on "bp->in_target_beneath == in_target_beneath", to be safer. gdb: 2016-04-07 Yao Qi <yao.qi@linaro.org> * record-full.c (record_full_insert_breakpoint): Return early if entry on the address is found in record_full_breakpoints.	2016-04-07 16:51:31 +01:00

This caused a stack overflow when alloca was used. gdb/ChangeLog: * record-full.c (record_full_exec_insn): Use xmalloc for temporary memory storage.	2015-11-04 15:26:59 +01:00
Luis Machado	7cc53fba0a	Do not pass NULL for the string in catch_errors ... I caught a segmentation fault while running gdb.reverse/sigall-reverse.exp, in a mingw32 GDB, in this code path. It boils down to the code trying to strlen () a NULL pointer. I tracked things down and it looks like record_full_message_wrapper_safe is the only offender. gdb/ChangeLog: 2015-10-26 Luis Machado <lgustavo@codesourcery.com> * record-full.c (record_full_message_wrapper_safe): Pass empty string to catch_errors call instead of NULL.	2015-10-26 11:17:29 -02:00

Simon Marchi	224c3ddb89	Add casts to memory allocation related calls ... Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script. I fixed some bits by hand, but there might be some wrong parts left (hopefully not). gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_stap_parse_special_token): Add cast to allocation result assignment. * ada-exp.y (write_object_renaming): Likewise.

Simon Marchi	8d7493201c	Replace some xmalloc-family functions with XNEW-family ones ... This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files. For those I'll have to rely on the buildbot or people complaining that I broke their gdb. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_add_process): Likewise. * aarch64-tdep.c (aarch64_gdbarch_init): Likewise. * ada-exp.y (write_ambiguous_var): Likewise. * ada-lang.c (resolve_subexp): Likewise.

Simon Marchi	aead7601eb	Add casts for legitimate integer to enum conversions ... This patch is mostly extracted from Pedro's C++ branch. It adds explicit casts from integer to enum types, where it is really the intention to do so. This could be because we are ... * iterating on enum values (we need to iterate on an equivalent integer) * converting from a value read from bytes (dwarf attribute, agent expression opcode) to the equivalent enum * reading the equivalent integer value from another language (Python/Guile) An exception to that is the casts in regcache.c. It seems to me like struct regcache's register_status field could be a pointer to an array of enum register_status. Doing so would waste a bit of memory (4 bytes used by the enum vs 1 byte used by the current signed char, for each register). If we switch to C++11 one day, we can define the underlying type of an enum type, so we could have the best of both worlds. gdb/ChangeLog: * arm-tdep.c (set_fp_model_sfunc): Add cast from integer to enum.

Pedro Alves	6a3753b34b	Simplify target_async hook interface ... All callers of target_async pass it the same callback (inferior_event_handler). Since both common code and target backends need to be able to put the target in and out of target async mode at any given time, there's really no way that a different callback could be passed. This commit simplifies things, and removes the indirection altogether. Bonus: with this, gdb's target_async method ends up with the same signature as gdbserver's. Tested on x86_64 Fedora 20, native and gdbserver. gdb/ChangeLog: 2015-03-25 Pedro Alves <palves@redhat.com> * target.h <to_async>: Replace 'callback' and 'context' parameters with boolean 'enable' parameter.
