2017-03-20Change {lookup,make}_reference_type APIArtemiy Volkov2-2/+2
Parameterize lookup_reference_type() and make_reference_type() by the kind of reference type we want to look up. Create two wrapper functions lookup_{lvalue,rvalue}_reference_type() for lookup_reference_type() to simplify the API. Change all callers to use the new API. gdb/Changelog PR gdb/14441 * dwarf2read.c (read_tag_reference_type): Use lookup_lvalue_reference_type() instead of lookup_reference_type(). * eval.c (evaluate_subexp_standard): Likewise. * f-exp.y: Likewise. * gdbtypes.c (make_reference_type, lookup_reference_type): Generalize with rvalue reference types.

2017-02-02Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchyPedro Alves6-129/+46
This patch starts from the desire to eliminate make_cleanup_ui_file_delete, but then goes beyond. It makes ui_file & friends a real C++ class hierarchy, and switches temporary ui_file-like objects to stack-based allocation. - mem_fileopen -> string_file mem_fileopen is replaced with a new string_file class that is treated as a value class created on the stack. This alone eliminates most make_cleanup_ui_file_delete calls, and, simplifies code a whole lot (diffstat shows around 1k loc dropped.) string_file's internal buffer is a std::string, thus the "string" in the name. This simplifies the implementation much, compared to mem_fileopen, which managed growing its internal buffer manually. - ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone The new string_file class has a string() method that provides direct writable access to the internal std::string buffer. This replaced ui_file_as_string, which forced a copy of the same data the stream had inside. With direct access via a writable reference, we can instead move the string out of the string_stream, avoiding deep string copying. Related, ui_file_xstrdup calls are replaced with xstrdup'ping the stream's string, and ui_file_obsavestring is replaced by obstack_copy0. With all those out of the way, getting rid of the weird ui_file_put mechanism was possible. - New ui_file::printf, ui_file::puts, etc. methods These simplify / clarify client code. I considered splitting client-code changes, like these, e.g.: - stb = mem_fileopen (); - fprintf_unfiltered (stb, "%s%s%s", - _("The valid values are:\n"), - regdesc, - _("The default is \"std\".")); + string_file stb; + stb.printf ("%s%s%s", + _("The valid values are:\n"), + regdesc, + _("The default is \"std\".")); In two steps, with the first step leaving fprintf_unfiltered (etc.) calls in place, and only afterwards do a pass to change all those to call stb.printf etc.. I didn't do that split, because (when I tried), it turned out to be pointless make-work: the first pass would have to touch the fprintf_unfiltered line anyway, to replace "stb" with "&stb". - gdb_fopen replaced with stack-based objects This avoids the need for cleanups or unique_ptr's. I.e., this: struct ui_file *file = gdb_fopen (filename, "w"); if (filename == NULL) perror_with_name (filename); cleanups = make_cleanup_ui_file_delete (file); // use file. do_cleanups (cleanups); is replaced with this: stdio_file file; if (!file.open (filename, "w")) perror_with_name (filename); // use file. - odd contorsions in null_file_write / null_file_fputs around when to call to_fputs / to_write eliminated. - Global null_stream object A few places that were allocating a ui_file in order to print to "nowhere" are adjusted to instead refer to a new 'null_stream' global stream. - TUI's tui_sfileopen eliminated. TUI's ui_file much simplified The TUI's ui_file was serving a dual purpose. It supported being used as string buffer, and supported being backed by a stdio FILE. The string buffer part is gone, replaced by using of string_file. The 'FILE *' support is now much simplified, by making the TUI's ui_file inherit from stdio_file. gdb/ChangeLog: 2017-02-02 Pedro Alves <palves@redhat.com> * ada-lang.c (type_as_string): Use string_file. * ada-valprint.c (ada_print_floating): Use string_file. * ada-varobj.c (ada_varobj_scalar_image) (ada_varobj_get_value_image): Use string_file. * aix-thread.c (aix_thread_extra_thread_info): Use string_file. * arm-tdep.c (_initialize_arm_tdep): Use string_printf. * breakpoint.c (update_inserted_breakpoint_locations) (insert_breakpoint_locations, reattach_breakpoints) (print_breakpoint_location, print_one_detail_ranged_breakpoint) (print_it_watchpoint): Use string_file.

2017-01-26Refactor disassembly codeYao Qi1-57/+20
This patch addes class gdb_disassembler, and refactor code to use it. The gdb_disassembler object is saved in disassember_info.application_data. However, disassember_info.application_data is already used by gdb for arm, mips spu, and scm-disasm. In arm and mips, .application_data is gdbarch, but we can still get gdbarch from gdb_disassember. The use of application_data in spu is a little bit complicated. It creates its own disassemble_info, and save spu_dis_asm_data in .application_data. This will overwrite the pointer to gdb_disassembler, so we need to find another place to save spu_dis_asm_data. I extend disassemble_info, and put "id" there. gdb: 2017-01-26 Pedro Alves <palves@redhat.com> Yao Qi <yao.qi@linaro.org> * arm-tdep.c: Include "disasm.h".

2016-12-22Class-ify ui_outSimon Marchi2-3/+3
This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

2016-11-21Create subobject value in pretty printerYao Qi1-10/+1
Nowadays, we create a value of subobject in pretty printer with 'address' being used, value = value_from_contents_and_address (type, valaddr + embedded_offset, address + embedded_offset); set_value_component_location (value, val); /* set_value_component_location resets the address, so we may need to set it again. */ if (VALUE_LVAL (value) != lval_internalvar && VALUE_LVAL (value) != lval_internalvar_component && VALUE_LVAL (value) != lval_computed) set_value_address (value, address + embedded_offset); value_from_contents_and_address creates a value from memory, but the value we are pretty-printing may not from memory at all. Instead of using value_from_contents_and_address, we create a value of subobject with the same location as object's but different offset. We avoid using address in this way. As a result, parameter 'address' in apply_val_pretty_printer is no longer needed, we can remove it in next step. We've already had the location of the 'whole' value, so it is safe to assume we can create a value of 'component' or 'suboject' value at the same location but with different offset. gdb: 2016-11-21 Yao Qi <yao.qi@linaro.org> * guile/scm-pretty-print.c (gdbscm_apply_val_pretty_printer): Don't call value_from_contents_and_address and set_value_address.

The wildebeest-debian-wheezy-i686 buildslave's build is broken due to: ../../binutils-gdb/gdb/python/python.c: In function void _initialize_python(): ../../binutils-gdb/gdb/python/python.c:1709:36: error: missing sentinel in function call [-Werror=format] Reproduced on Fedora 23 by sticking a few: #undef NULL #define 0 in build/gdb/build-gnulib/{stddef|signal|stdio}.h.

2016-04-12Introduce interruptible_selectPedro Alves1-1/+3
We have places where we call a blocking gdb_select expecting that a Ctrl-C will unblock it. However, if the Ctrl-C is pressed just before gdb_select, the SIGINT handler runs before gdb_select, and thus gdb_select won't return. For example gdb_readline_no_editing: QUIT; /* Wait until at least one byte of data is available. Control-C can interrupt gdb_select, but not fgetc. */ FD_ZERO (&readfds); FD_SET (fd, &readfds); if (gdb_select (fd + 1, &readfds, NULL, NULL, NULL) == -1) and stdio_file_read: /* For the benefit of Windows, call gdb_select before reading from the file. Wait until at least one byte of data is available. Control-C can interrupt gdb_select, but not read. */ { fd_set readfds; FD_ZERO (&readfds); FD_SET (stdio->fd, &readfds); if (gdb_select (stdio->fd + 1, &readfds, NULL, NULL, NULL) == -1) return -1; } return read (stdio->fd, buf, length_buf); This is a race classically fixed with either the self-pipe trick, or by blocking SIGINT and then using pselect instead of select. Blocking SIGINT most of the time would mean that check_quit_flag (and thus QUIT) would need to do a syscall every time it is called, which sounds best avoided, since QUIT is called in many loops. Thus we take the self-pipe trick route (wrapped in a serial event). Instead of having all places that need this manually add an extra file descriptor to the set of gdb_select's watched file descriptors, we introduce a wrapper, interruptible_select, that does that. The Windows version of gdb_select actually does not suffer from this, because mingw-hdep.c:gdb_call_async_signal_handler sets a Windows event that gdb_select always waits on. So this patch can be seen as generalization of that technique. We can't remove that extra event from mingw-hdep.c until we get rid of immediate_quit though. gdb/ChangeLog: 2016-04-12 Pedro Alves <palves@redhat.com> * defs.h: Extend QUIT-related comments to mention interruptible_select.

2016-01-13Per-inferior/Inferior-qualified thread IDsPedro Alves1-4/+4
This commit changes GDB to track thread numbers per-inferior. Then, if you're debugging multiple inferiors, GDB displays "inferior-num.thread-num" instead of just "thread-num" whenever it needs to display a thread: (gdb) info inferiors Num Description Executable 1 process 6022 /home/pedro/gdb/tests/threads * 2 process 6037 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame 1.1 Thread 0x7ffff7fc2740 (LWP 6022) "threads" (running) 1.2 Thread 0x7ffff77c0700 (LWP 6028) "threads" (running) 1.3 Thread 0x7ffff7fc2740 (LWP 6032) "threads" (running) 2.1 Thread 0x7ffff7fc1700 (LWP 6037) "threads" (running) 2.2 Thread 0x7ffff77c0700 (LWP 6038) "threads" (running) * 2.3 Thread 0x7ffff7fc2740 (LWP 6039) "threads" (running) (gdb) ... (gdb) thread 1.1 [Switching to thread 1.1 (Thread 0x7ffff7fc2740 (LWP 8155))] (gdb) ... etc. You can still use "thread NUM", in which case GDB infers you're referring to thread NUM of the current inferior. The $_thread convenience var and Python's InferiorThread.num attribute are remapped to the new per-inferior thread number. It's a backward compatibility break, but since it only matters when debugging multiple inferiors, I think it's worth doing. Because MI thread IDs need to be a single integer, we keep giving threads a global identifier, _in addition_ to the per-inferior number, and make MI always refer to the global thread IDs. IOW, nothing changes from a MI frontend's perspective. Similarly, since Python's Breakpoint.thread and Guile's breakpoint-thread/set-breakpoint-thread breakpoint methods need to work with integers, those are adjusted to work with global thread IDs too. Follow up patches will provide convenient means to access threads' global IDs. To avoid potencially confusing users (which also avoids updating much of the testsuite), if there's only one inferior and its ID is "1", IOW, the user hasn't done anything multi-process/inferior related, then the "INF." part of thread IDs is not shown. E.g,.: (gdb) info inferiors Num Description Executable * 1 process 15275 /home/pedro/gdb/tests/threads (gdb) info threads Id Target Id Frame * 1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) add-inferior Added inferior 2 (gdb) info threads Id Target Id Frame * 1.1 Thread 0x7ffff7fc1740 (LWP 15275) "threads" main () at threads.c:40 (gdb) No regressions on x86_64 Fedora 20. gdb/ChangeLog: 2016-01-13 Pedro Alves <palves@redhat.com> * NEWS: Mention that thread IDs are now per inferior and global thread IDs. * Makefile.in (SFILES): Add tid-parse.c.

There is a handful of calls to scm_dynwind_begin (0); where the parameter is an enum, scm_t_dynwind_flags.

2015-10-26Fix constness problem in ioscm_make_gdb_stdio_portSimon Marchi1-4/+11
ioscm_make_gdb_stdio_port passes const char pointers (literal strings) to scm_mode_bits, which takes a non-const char pointer. Ideally, we would change scm_mode_bits to take a const char pointer, but it's not part of an API we control. Instead, it's easy enough to build the string to pass to scm_mode_bits in a (non-const) char array and pass that. gdb/ChangeLog: * guile/scm-ports.c (ioscm_make_gdb_stdio_port): Pass non-const char pointer to scm_mode_bits.

2015-10-26scm-symbol.c: Add (domain_enum) castsSimon Marchi1-2/+3
We currently pass integers as domain_enums to lookup_symbol. The most obvious fix is to add casts there. I first thought of changing the type of the domain variables to domain_enum. However, because we pass a pointer to them to gdbscm_parse_function_args, which expects them to be integers (because of the format string), I don't think it would be correct. If the enum does not have the same size as an int, gdbscm_parse_function_args could write past the memory of domain, overwriting something else on the stack. gdb/ChangeLog: * guile/scm-symbol.c (gdbscm_lookup_global_symbol): Add domain_enum cast. (gdbscm_lookup_symbol): Likewise.
2015-09-25Add some more casts (1/2)Simon Marchi14-67/+72
Note: I needed to split this patch in two, otherwise it's too big for the mailing list. This patch adds explicit casts to situations where a void pointer is assigned to a pointer to the "real" type. Building in C++ mode requires those assignments to use an explicit cast. This includes, for example: - callback arguments (cleanups, comparison functions, ...) - data attached to some object (objfile, program space, etc) in the form of a void pointer - "user data" passed to some function This patch comes from the commit "(mostly) auto-generated patch to insert casts needed for C++", taken from Pedro's C++ branch. Only files built on x86 with --enable-targets=all are modified, so the native files for other arches will need to be dealt with separately. I built-tested this with --enable-targets=all and reg-tested. To my surprise, a test case (selftest.exp) had to be adjusted. Here's the ChangeLog entry. Again, this was relatively quick to make despite the length, thanks to David Malcom's script, although I don't believe it's very useful information in that particular case... gdb/ChangeLog: * aarch64-tdep.c (aarch64_make_prologue_cache): Add cast(s).

2015-09-25Add casts to memory allocation related callsSimon Marchi4-13/+18
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.

2015-08-26Replace some xmalloc-family functions with XNEW-family onesSimon Marchi3-5/+4
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.

2015-08-25DWARF: handle non-local references in nested functionsPierre-Marie de Rodat2-3/+12
GDB's current behavior when dealing with non-local references in the context of nested fuctions is approximative: - code using valops.c:value_of_variable read the first available stack frame that holds the corresponding variable (whereas there can be multiple candidates for this); - code directly relying on read_var_value will instead read non-local variables in frames where they are not even defined. This change adds the necessary context to symbol reads (to get the block they belong to) and to blocks (the static link property, if any) so that GDB can make the proper decisions when dealing with non-local varibale references. gdb/ChangeLog: * ada-lang.c (ada_read_var_value): Add a var_block argument and pass it to default_read_var_value. * block.c (block_static_link): New accessor. * block.h (block_static_link): Declare it. * buildsym.c (finish_block_internal): Add a static_link argument.

2015-08-11Explicit locations: use new location APIKeith Seitz1-6/+17
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.

2015-08-06Add casts for legitimate integer to enum conversionsSimon Marchi1-1/+1
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.

2015-08-01Replace the block_found global with explicit data-flowPierre-Marie de Rodat2-3/+3
As Pedro suggested on gdb-patches@ (see https://sourceware.org/ml/gdb-patches/2015-05/msg00714.html), this change makes symbol lookup functions return a structure that includes both the symbol found and the block in which it was found.

2015-07-31Mostly trivial enum fixesSimon Marchi5-7/+7
This is a patch I extracted from Pedro's C++ branch. It contains the most trivial enum fixes, where an integer type/value was used instead of the appropriate enum type/value. It fixes many C++ errors, since in C++ you can't mix integers and enums implicitely. Regardless of the C++ conversion, I think this is a good cleanup to make use of the appropriate enum types. Regression-tested on native x86_64. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_linux_can_use_hw_breakpoint): Use enum type or value instead of integer. (aarch64_linux_insert_watchpoint): Likewise.

2015-07-14Remove CHECK_TYPEDEF, use check_typedef insteadSimon Marchi2-9/+9
I think that the CHECK_TYPEDEF macro is not necessary, and even a bit annoying. It makes unclear the fact that the "type" variables gets overwritten. It has actually bitten me a few times. I think the following, explicit form, is better. type = check_typedef (type); This patches changes all instances of CHECK_TYPEDEF for an equivalent call to check_typedef. The bulk of the change was done with this sed: sed -i 's/CHECK_TYPEDEF (\([^)]*\));/\1 = check_typedef (\1);/' <file>.c The ChangeLog was generated using David Malcom's generate_changelog.py. I manually fixed those places where it gets the wrong function name, hopefully all of them. The patch was built-tested, and I ran a few smoke tests. gdb/ChangeLog: * gdbtypes.h (CHECK_TYPEDEF): Remove. * aarch64-tdep.c (aarch64_return_in_memory): Replace CHECK_TYPEDEF with check_typedef. * ada-lang.c (decode_constrained_packed_array_type): Likewise.

2015-04-11Remove --xdbJan Kratochvil1-1/+1
Pedro Alves: The commands that enables aren't even documented in the manual. Judging from that, I assume that only wdb users would ever really be using the --xdb switch. I think it's time to drop "support" for the --xdb switch too. I looked through the commands that that exposes, the only that looked potentially interesting was "go", but then it's just an alias for "tbreak+jump", which can easily be done with "define go...end". I'd rather free up the "go" name for something potentially more interesting (either run control, or maybe even unrelated, e.g., for golang). gdb/ChangeLog 2015-04-11 Jan Kratochvil <jan.kratochvil@redhat.com> * NEWS (Changes since GDB 7.9): Add removed -xdb. * breakpoint.c (command_line_is_silent): Remove xdb_commands conditional.
