2023-05-01gdb: move struct ui and related things to ui.{c,h}Simon Marchi1-1/+1
I'd like to move some things so they become methods on struct ui. But first, I think that struct ui and the related things are big enough to deserve their own file, instead of being scattered through top.{c,h} and event-top.c. Change-Id: I15594269ace61fd76ef80a7b58f51ff3ab6979bc
2023-03-30PR gdb/30219: Clear sync_quit_force_run in quit_forceKevin Buettner1-0/+1
PR 30219 shows an internal error due to a "Bad switch" in print_exception() in gdb/exceptions.c. The switch in question contains cases for RETURN_QUIT and RETURN_ERROR, but is missing a case for the recently added RETURN_FORCED_QUIT. This commit adds that case. Making the above change allows the errant test case to pass, but does not fix the underlying problem, which I'll describe shortly. Even though the addition of a case for RETURN_FORCED_QUIT isn't the actual fix, I still think it's important to add this case so that other situations which lead to print_exeption() being called won't generate that "Bad switch" internal error. In order to understand the underlying problem, please examine this portion of the backtrace from the bug report: 0x5576e4ff5780 print_exception /home/smarchi/src/binutils-gdb/gdb/exceptions.c:100 0x5576e4ff5930 exception_print(ui_file*, gdb_exception const&) /home/smarchi/src/binutils-gdb/gdb/exceptions.c:110 0x5576e6a896dd quit_force(int*, int) /home/smarchi/src/binutils-gdb/gdb/top.c:1849 The real problem is in quit_force; here's the try/catch which eventually leads to the internal error: /* Get out of tfind mode, and kill or detach all inferiors. */ try { disconnect_tracing (); for (inferior *inf : all_inferiors ()) kill_or_detach (inf, from_tty); } catch (const gdb_exception &ex) { exception_print (gdb_stderr, ex); } While running the calls in the try-block, a QUIT check is being performed. This check finds that sync_quit_force_run is (still) set, causing a gdb_exception_forced_quit to be thrown. The exception gdb_exception_forced_quit is derived from gdb_exception, causing exception_print to be called. As shown by the backtrace, print_exception is then called, leading to the internal error. The actual fix, also implemented by this commit, is to clear sync_quit_force_run along with the quit flag. This will allow the various cleanup code, called by quit_force, to run without triggering a gdb_exception_forced_quit. (Though, if another SIGTERM is sent to the gdb process, these flags will be set again and a QUIT check in the cleanup code will detect it and throw the exception.)

2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+1
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-10-19internal_error: remove need to pass __FILE__/__LINE__Pedro Alves1-1/+1
Currently, every internal_error call must be passed __FILE__/__LINE__ explicitly, like: internal_error (__FILE__, __LINE__, "foo %d", var); The need to pass in explicit __FILE__/__LINE__ is there probably because the function predates widespread and portable variadic macros availability. We can use variadic macros nowadays, and in fact, we already use them in several places, including the related gdb_assert_not_reached. So this patch renames the internal_error function to something else, and then reimplements internal_error as a variadic macro that expands __FILE__/__LINE__ itself. The result is that we now should call internal_error like so: internal_error ("foo %d", var); Likewise for internal_warning. The patch adjusts all calls sites. 99% of the adjustments were done with a perl/sed script. The non-mechanical changes are in gdbsupport/errors.h, gdbsupport/gdb_assert.h, and gdb/gdbarch.py.

2022-03-29Remove unnecessary calls to wrap_here and gdb_flushTom Tromey1-7/+3
Various spots in gdb currently know about the wrap buffer, and so are careful to call wrap_here to be certain that all output has been flushed. Now that the pager is just an ordinary stream, this isn't needed, and a simple call to gdb_flush is enough. Similarly, there are places where gdb prints to gdb_stderr, but first flushes gdb_stdout. stderr_file already flushes gdb_stdout, so these aren't needed.
2022-03-29Unify gdb printf functionsTom Tromey1-1/+1
Now that filtered and unfiltered output can be treated identically, we can unify the printf family of functions. This is done under the name "gdb_printf". Most of this patch was written by script.
2022-03-29Unify gdb puts functionsTom Tromey1-1/+1
Now that filtered and unfiltered output can be treated identically, we can unify the puts family of functions. This is done under the name "gdb_puts". Most of this patch was written by script.
2022-03-29Unify vprintf functionsTom Tromey1-1/+1
Now that filtered and unfiltered output can be treated identically, we can unify the vprintf family of functions: vprintf_filtered, vprintf_unfiltered, vfprintf_filtered and vfprintf_unfiltered. (For the gdb_stdout variants, recall that only printf_unfiltered gets truly unfiltered output at this point.) This removes one such function and renames the remaining two to "gdb_vprintf". All callers are updated. Much of this patch was written by script.
2022-01-26Always call the wrap_here methodTom Tromey1-1/+1
This changes all existing calls to wrap_here to call the method on the appropriate ui_file instead. The choice of ui_file is determined by context.
2022-01-26Convert wrap_here to use integer parameterTom Tromey1-1/+1
I think it only really makes sense to call wrap_here with an argument consisting solely of spaces. Given this, it seemed better to me that the argument be an int, rather than a string. This patch is the result. Much of it was written by a script.

2021-07-30Replace exception_print_same with operator!=Tom Tromey1-14/+0
I noticed that exception_print_same is only used in a single spot, and it seemed to be better as an operator!= method attached to gdb_exception. Regression tested on x86-64 Fedora 34.

2019-07-09Rename common to gdbsupportTom Tromey1-1/+1
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty.

2019-04-08Make exceptions use std::string and be self-managingTom Tromey1-8/+3
This changes the exception's "message" member to be a shared_ptr wrapping a std::string. This allows removing the stack of exception messages, because now exceptions will self-destruct when needed. This also adds a noexcept copy constructor and operator= to gdb_exception, plus a "what" method. gdb/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * xml-support.c (gdb_xml_parser::parse): Update. * x86-linux-nat.c (x86_linux_nat_target::enable_btrace): Update. * value.c (show_convenience): Update. * unittests/cli-utils-selftests.c (test_number_or_range_parser) (test_parse_flags_qcs): Update. * thread.c (thr_try_catch_cmd): Update. * target.c (target_translate_tls_address): Update. * stack.c (print_frame_arg, read_frame_local, read_frame_arg) (info_frame_command_core, frame_apply_command_count): Update. * rust-exp.y (rust_lex_exception_test): Update. * riscv-tdep.c (riscv_print_one_register_info): Update. * remote.c (remote_target::enable_btrace): Update. * record-btrace.c (record_btrace_enable_warn): Update. * python/py-utils.c (gdbpy_convert_exception): Update. * printcmd.c (do_one_display, print_variable_and_value): Update. * mi/mi-main.c (mi_print_exception): Update. * mi/mi-interp.c (mi_cmd_interpreter_exec): Use SCOPE_EXIT. * mi/mi-cmd-stack.c (list_arg_or_local): Update. * linux-nat.c (linux_nat_target::attach): Update. * linux-fork.c (class scoped_switch_fork_info): Update. * infrun.c (displaced_step_prepare): Update. * infcall.c (call_function_by_hand_dummy): Update. * guile/scm-exception.c (gdbscm_scm_from_gdb_exception): Update. * gnu-v3-abi.c (print_one_vtable): Update. * frame.c (get_prev_frame_always): Update. * f-valprint.c (info_common_command_for_block): Update. * exec.c (try_open_exec_file): Update. * exceptions.c (print_exception, exception_print) (exception_fprintf, exception_print_same): Update. * dwarf2-frame.c (dwarf2_build_frame_info): Update. * dwarf-index-cache.c (index_cache::store) (index_cache::lookup_gdb_index): Update. * darwin-nat.c (maybe_cache_shell): Update. * cp-valprint.c (cp_print_value_fields): Update. * compile/compile-cplus-symbols.c (gcc_cplus_convert_symbol) (gcc_cplus_symbol_address): Update. * compile/compile-c-symbols.c (gcc_convert_symbol) (gcc_symbol_address, generate_c_for_for_one_variable): Update. * common/selftest.c: Update. * common/common-exceptions.h (struct gdb_exception) <message>: Now a std::string.

This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-06-07target_stack -> current_top_target() throughoutPedro Alves1-1/+1
The recent C++ification of target_ops replaced references to the old "current_target" squashed target throughout with references to a "target_stack" pointer. I had picked the "target_stack" name very early in the multi-target work, and managed to stick with it, even though it's a bit of a misnomer, since it isn't really a "target stack" object, but a pointer into the current top target in the stack. As I'm splitting more pieces off of the multi-target branch, I've come to think that it's better to rename it now. A following patch will introduce a new class to represent a target stack, and "target_stack" would be _its_ ideal name. (In the branch, the class is called a_target_stack to work around the clash.) Thus this commit renames target_stack to current_top_target and replaces all references throughout. Also, while at it, current_top_target is made a function instead of a pointer, to make it possible to change its internal implementation without leaking implementation details out. In a couple patches, the implementation of the function will change to refer to a target stack object, and then further down the multi-target work, it'll change again to find the right target stack for the current inferior. gdb/ChangeLog: 2018-06-07 Pedro Alves <palves@redhat.com> * target.h (target_stack): Delete.

2018-05-03Convert struct target_ops to C++Pedro Alves1-1/+5
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.

gdb/ChangeLog: Update copyright year range in all GDB files
2017-10-10Eliminate catch_exceptions/catch_exceptions_with_msgPedro Alves1-83/+0
This patch gets rid of catch_exceptions / catch_exceptions_with_msg. The latter is done mostly by getting rid of the three remaining vestigial libgdb wrapper functions, which are really pointless nowadays. This results in a good number of simplifications. (I checked that Insight doesn't use those functions.) The gdb.mi/mi-pthreads.exp change is necessary because this actually fixes a bug, IMO -- the patch stops MI's -thread-select causing output on the CLI stream. I.e., before: -thread-select 123456789 &"Thread ID 123456789 not known.\n" ^error,msg="Thread ID 123456789 not known." (gdb) After: -thread-select 123456789 ^error,msg="Thread ID 123456789 not known."

2017-10-10Eliminate catch_errorsPedro Alves1-39/+0
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.

2017-09-20Remove make_cleanup_restore_target_terminalTom Tromey1-5/+4
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.

2016-10-26PR 20569, segv in follow_execSandra Loosemore1-0/+18
The following testcases make GDB crash whenever an invalid sysroot is provided, when GDB is unable to find a valid path to the symbol file: gdb.base/catch-syscall.exp gdb.base/execl-update-breakpoints.exp gdb.base/foll-exec-mode.exp gdb.base/foll-exec.exp gdb.base/foll-vfork.exp gdb.base/pie-execl.exp gdb.multi/bkpt-multi-exec.exp gdb.python/py-finish-breakpoint.exp gdb.threads/execl.exp gdb.threads/non-ldr-exc-1.exp gdb.threads/non-ldr-exc-2.exp gdb.threads/non-ldr-exc-3.exp gdb.threads/non-ldr-exc-4.exp gdb.threads/thread-execl.exp The immediate cause of the segv is that follow_exec is passing a NULL argument (the result of exec_file_find) to strlen. However, the problem is deeper than that: follow_exec simply isn't prepared for the case where sysroot translation fails to locate the new executable. Actually all callers of exec_file_find have bugs due to confusion between host and target pathnames. This commit attempts to fix all that. In terms of the testcases that were formerly segv'ing, GDB now prints a warning but continues execution of the new program, so that the tests now mostly FAIL instead. You could argue the FAILs are due to a legitimate problem with the test environment setting up the sysroot translation incorrectly. A new representative test is added which exercises the ne wwarning code path even with native testing. Tested on x86_64 Fedora 23, native and gdbserver. gdb/ChangeLog: 2016-10-25 Sandra Loosemore <sandra@codesourcery.com> Luis Machado <lgustavo@codesourcery.com> Pedro Alves <palves@redhat.com> PR gdb/20569 * exceptions.c (exception_print_same): Moved here from exec.c. * exceptions.h (exception_print_same): Declare. * exec.h: Include "symfile-add-flags.h".

2016-04-12Eliminate immediate_quitPedro Alves1-7/+1
This finally gets rid of immediate_quit (and surrounding infrustruture), as nothing sets it anymore. gdb_call_async_signal_handler was only necessary in order to handle immediate_quit. We can just call mark_async_signal_handler directly on all hosts now. In turn, we can clean up mingw-hdep.c's gdb_select a bit, as sigint_event / sigint_handler is no longer needed. gdb/ChangeLog: 2016-04-12 Pedro Alves <palves@redhat.com> * defs.h: Update comments on SIGINT handling.

2016-04-12Don't call clear_quit_flag in prepare_to_throw_exceptionPedro Alves1-1/+0
I think this is reminiscent of the time when a longjmp would always jump to the top level. Nowaways code that throw exceptions other than a quit, which may even be caught and handled without reaching the top level. Certainly such exceptions shouldn't clear an interrupt request... (We also need to get rid of prepare_to_throw_exception in order to be able to just do "throw ex;" in C++.) One could argue that we should clear the quit flag when we throw a quit from the SIGINT handler, when immediate_quit is in effect, to handle a race, here: immediate_quit++; QUIT; ... that's the usual pattern code must use when enabling immediate_quit. The QUIT is there to catch the case of Ctrl-C having already been pressed before immediate_quit was enabled. However, this can happen: immediate_quit++; << Ctrl-C pressed here too. QUIT; And in that case, if the quit flag was already set, it'll stay set even after throwing a quit from the SIGINT handler. The end result is a double quit. But OTOH, the user did press Ctrl-C two times. Since I'm getting rid of immediate_quit, I'm not bothering with this. gdb/ChangeLog: 2016-04-12 Pedro Alves <palves@redhat.com> * exceptions.c (prepare_to_throw_exception): Don't clear the quit flag.

2015-03-07Split TRY_CATCH into TRY + CATCHPedro Alves1-5/+10
This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception.

2015-03-07Normalize TRY_CATCH exception handling blockPedro Alves1-2/+7
This normalizes some exception catch blocks that check for ex.reason to look like this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ALL) { ... } if (ex.reason < 0) { ... } ~~~ This is a preparation step for running a script that converts all TRY_CATCH uses to look like this instead: ~~~ TRY { ... } CATCH (ex, RETURN_MASK_ALL) { ... } END_CATCH ~~~ The motivation for that change is being able to reimplent TRY/CATCH in terms of C++ try/catch. This commit makes it so that: - no condition other than ex.reason < 0 is checked in the if predicate - there's no "else" block to check whether no exception was caught - there's no code between the TRY_CATCH (TRY) block and the 'if (ex.reason < 0)' block (CATCH). - the exception object is no longer referred to outside the if/catch block. Note the local volatile exception objects that are currently defined inside functions that use TRY_CATCH will disappear. In cases it's more convenient to still refer to the exception outside the catch block, a new non-volatile local is added and copy to that object is made within the catch block.

2014-07-24Rationalize "fatal" error handling outside of gdbserverGary Benson1-2/+12
GDB and gdbserver have functions named "fatal" that are used in completely different ways. In gdbserver "fatal" is used to handle critical errors: it differs from "error" in that "fatal" causes gdbserver to exit whereas "error" does not. In GDB "fatal" is used to abort the current operation and return to the command level. This is implemented by throwing a non-error "RETURN_QUIT" exception. This commit removes GDB's "fatal" and "vfatal" functions entirely. The exception-throwing function "throw_vfatal" is renamed as "throw_vquit", and a new convenience function "throw_quit" is added. The small number of calls to "fatal" are replaced with calls to "throw_quit", making what is happening more obvious. This commit also modifies GDB's "throw_error" to call "throw_verror" rather than calling "throw_it" directly. This change means the assignment of RETURN_ERROR as the exception type now happens in precisely one place in GDB rather than two. gdb/ 2014-07-24 Gary Benson <gbenson@redhat.com> * exceptions.h (throw_vfatal): Renamed to... (throw_vquit): New declaration. (throw_quit): Likewise. * exceptions.c (throw_vfatal): Renamed to... (throw_vquit): New function. (throw_quit): Likewise. (throw_error): Call throw_verror rather than throw_it. * utils.h (vfatal): Removed. (fatal): Likewise. * utils.c (vfatal): Removed. (fatal): Likewise. (internal_verror): Replaced call to fatal with call to throw_quit. (quit): Replaced calls to fatal with calls to throw_quit.
2014-07-14Move catch_command_errors and catch_command_errors_const to main.cPedro Alves1-32/+0
We'll need to add error handling code to commands run before the event loop starts (commands in .gdbinit, -ex commands, etc.). Turns out those are run through catch_command_errors, and, catch_command_errors is used nowhere else. Move it (and the _const variant) to main.c, so that we can further specialize it freely. gdb/ 2014-07-14 Pedro Alves <palves@redhat.com> * exceptions.c (catch_command_errors, catch_command_errors_const): Moved to main.c. * exceptions.h (catch_command_errors_ftype) (catch_command_errors_const_ftype): Moved to main.c. (catch_command_errors, catch_command_errors_const): Delete declarations. * main.c (catch_command_errors_ftype) (catch_command_errors_const_ftype): Moved here from exceptions.h. (catch_command_errors, catch_command_errors_const)): Moved here from exceptions.c and make static.
2014-07-14Eliminate exceptions.c:print_any_exception.Pedro Alves1-22/+4
exception_print and exception_fprintf call print_flush, which does all the same flushing and annotation things that print_any_exception does, and more. gdb/ 2014-07-14 Pedro Alves <palves@redhat.com> * exceptions.c (print_any_exception): Delete. (catch_exceptions_with_msg): Use exception_print instead of print_any_exception. (catch_errors): Use exception_fprintf instead of print_any_exception. (catch_command_errors, catch_command_errors_const): Use exception_print instead of print_any_exception.
