2019-03-07gdb: Move value_from_host_double into value.c and make more use of itAndrew Burgess2-16/+3
The function value_from_host_double can be moved from f-lang.c into value.c as a generally useful function, and then used more widely. Tested on X86-64/GNU Linux with no regressions. gdb/ChangeLog: * f-lang.c (value_from_host_double): Moved to... * value.c (value_from_host_double): ...here. * value.h (value_from_host_double): Declare. * guile/scm-math.c (vlscm_convert_typed_number): Use value_from_host_double. (vlscm_convert_number): Likewise. * guile/scm-value.c (gdbscm_value_to_real): Likewise. * python/py-value.c (convert_value_from_python): Likewise.
2019-02-07Normalize include guards in gdbTom Tromey2-6/+7
While working on my other scripts to deal with gdb headers, I noticed that some files were missing include guards. I wrote a script to add the missing ones, but found that using the obvious names for the guards ran into clashes -- for example, gdb/nat/linux-nat.h used "LINUX_NAT_H", but this was also the script's choice for gdb/linux-nat.h. So, I changed the script to normalize all include guards in gdb. This patch is the result. As usual the script is available here: https://github.com/tromey/gdb-refactoring-scripts Tested by rebuilding; I also ran it through "Fedora-x86_64-m64" on the buildbot. gdb/ChangeLog 2019-02-07 Tom

2019-01-01Update copyright year range in all GDB files.Joel Brobecker35-35/+35
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.
2018-11-21Use gdb:array_view in call_function_by_hand & friendsPedro Alves1-2/+2
This replaces a few uses of pointer+length with gdb::array_view, in call_function_by_hand and related code. Unfortunately, due to -Wnarrowing, there are places where we can't brace-initialize an gdb::array_view without an ugly-ish cast. To avoid the cast, this patch introduces a gdb::make_array_view function. Unit tests included. This patch in isolation may not look so interesting, due to gdb::make_array_view uses, but I think it's still worth it. Some of the gdb::make_array_view calls disappear down the series, and others could be eliminated with more (non-trivial) gdb::array_view detangling/conversion (e.g. code around eval_call). See this as a "we have to start somewhere" patch. gdb/ChangeLog: 2018-11-21 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_evaluate_subexp): Adjust to pass an array_view. * common/array-view.h (make_array_view): New. * compile/compile-object-run.c (compile_object_run): Adjust to pass an array_view. * elfread.c (elf_gnu_ifunc_resolve_addr): Adjust. * eval.c (eval_call): Adjust to pass an array_view.

2018-10-04Shadowing fix in gdbscm_frame_read_varTom Tromey1-1/+0
-Wshadow=local pointed out that the shadowing in gdbscm_frame_read_var means that the ultimate call to read_var_value will always be passed block==NULL. The fix is to remove the inner declaration. gdb/ChangeLog 2018-10-04 Tom Tromey <tom@tromey.com> * guile/scm-frame.c (gdbscm_frame_read_var): Remove inner declaration of "block".
2018-10-04Simple -Wshadow=local fixesTom Tromey1-2/+2
This fixes all the straightforward -Wshadow=local warnings in gdb. A few standard approaches are used here: * Renaming an inner (or outer, but more commonly inner) variable; * Lowering a declaration to avoid a clash; * Moving a declaration into a more inner scope to avoid a clash, including the special case of moving a declaration into a loop header. I did not consider any of the changes in this patch to be particularly noteworthy, though of course they should all still be examined. gdb/ChangeLog 2018-10-04 Tom Tromey <tom@tromey.com> * ctf.c (SET_ARRAY_FIELD): Rename "u32". * p-valprint.c (pascal_val_print): Split inner "i" variable. * xtensa-tdep.c (xtensa_push_dummy_call): Declare "i" in loop header. * xstormy16-tdep.c (xstormy16_push_dummy_call): Declare "val" in more inner scope. * xcoffread.c (read_xcoff_symtab): Rename inner "symbol". * varobj.c (varobj_update): Rename inner "newobj", "type_changed". * valprint.c (generic_emit_char): Rename inner "buf". * valops.c (find_overload_match): Rename inner "temp".

2018-10-03Avoid two uninitialized warnings from gccTom Tromey1-1/+2
This avoids a couple of uninitialized warnings from gcc by initializing the object in question. The one in coffread.c seems like it could be a latent bug.

2018-09-17python: Make gdb.execute("show commands") work (PR 23669)Simon Marchi2-1/+7
Since commit 56bcdbea2bed ("Let gdb.execute handle multi-line commands") trying to use a command like gdb.execute("show commands") in Python fails. GDB ends up trying to run the "commands" command. The reason is that GDB gets confused with the special "commands" command. In process_next_line, the lookup_cmd_1 function returns the cmd_list_element representing the "commands" sub-command of "show". Lower, we check the cmd_list_element to see if it matches various control commands by name, including the "commands" command. This is where we wrongfully conclude that the executed command must be "commands", when in reality it was "show commands". The fix proposed in this patch removes the comparisons by name, instead comparing the cmd_list_element object by pointer with the objects created at initialization time. Tested on the buildbot, though on a single builder (Fedora-x86_64-m64). gdb/ChangeLog: PR python/23669 * breakpoint.c (commands_cmd_element): New.

2018-08-21Don't throw Scheme exceptions with live std::vector objectsPedro Alves1-77/+98
A complication with the Guile code is that we have two types of exceptions to consider: GDB/C++ exceptions, and Guile/SJLJ exceptions. Because Guile exceptions are SJLJ based, we must make sure to not have live local variables of types with non-trivial dtors when a Guile exception is thrown, because the dtors won't be run when a Guile exceptions is thrown. gdbscm_parse_function_args currently violates this: void gdbscm_parse_function_args (const char *func_name, int beginning_arg_pos, const SCM *keywords, const char *format, ...) { ... /* Keep track of malloc'd strings. We need to free them upon error. */ std::vector<char *> allocated_strings; ... for (char *ptr : allocated_strings) xfree (ptr); gdbscm_throw (status); /// dtor of "allocated_strings" is not run! } This commit fixes the above making using of gdbscm_wrap. It would be nice if we had a way to make it impossible to write such code.

Noticed by inspection. gdb/ChangeLog: 2018-07-19 Pedro Alves <palves@redhat.com> * guile/guile-internal.h (gdbscm_wrap): Really make 'args' a forwarding reference.
2018-07-18Eliminate cleanup in gdbscm_execute_gdb_commandPedro Alves1-21/+8
Note: the "may be modified" comment is no longer true nowadays. gdb/ChangeLog: 2018-07-18 Pedro Alves <palves@redhat.com> * guile/guile.c (gdbscm_execute_gdb_command): Adjust to use gdbscm_wrap. Use gdb::unique_xmalloc_ptr<char> instead of a cleanup.
2018-07-18Eliminate most remaining cleanups under gdb/guile/Pedro Alves6-561/+357
The main complication with the Guile code is that we have two types of exceptions to consider. GDB/C++ exceptions, and Guile/SJLJ exceptions. Code that is facing the Guile interpreter must not throw GDB exceptions, instead Scheme exceptions must be thrown. Also, because Guile exceptions are SJLJ based, Guile-facing code must not use local objects with dtors, unless wrapped in a scope with a TRY/CATCH, because the dtors won't otherwise be run when a Guile exceptions is thrown. This commit adds a new gdbscm_wrap wrapper function than encapsulates a pattern I noticed in many of the functions using GDBSCM_HANDLE_GDB_EXCEPTION_WITH_CLEANUPS. The wrapper is written such that you can pass either a lambda to it, or a function plus a variable number of forwarded args. I used a lambda when its body would be reasonably short, and a separate function in the larger cases. This also convers a few functions that were using GDBSCM_HANDLE_GDB_EXCEPTION to use gdbscm_wrap too because they followed a similar pattern. A few cases of make_cleanup calls are replaced with explicit xfree calls. The make_cleanup/do_cleanups calls in those cases are pointless, because do_cleanups won't be called when a Scheme exception is thrown. We also have a couple cases of Guile-facing code using RAII-type objects to manage memory, but those are incorrect, exactly because their dtor won't be called if a Guile exception is thrown. gdb/ChangeLog: 2018-07-18 Pedro Alves <palves@redhat.com> * guile/guile-internal.h: Add comment about mixing GDB and Scheme exceptions.

This changes gdbscm_exception_message_to_string to return a unique_xmalloc_ptr, allowing for the removal of some cleanups. unique_xmalloc_ptr was chosen because at the root of the call chains is a function from Guile that returns a malloc'd string. gdb/ChangeLog 2018-07-17 Tom Tromey <tom@tromey.com> * guile/scm-param.c (pascm_signal_setshow_error): Update. * guile/guile-internal.h (gdbscm_exception_message_to_string): Update. * guile/scm-cmd.c (cmdscm_function): Update. * guile/scm-pretty-print.c (ppscm_print_exception_unless_memory_error): Update. * guile/scm-exception.c (gdbscm_exception_message_to_string): Return unique_xmalloc_ptr.

2018-06-01Remove TYPE_TAG_NAMETom Tromey1-2/+8
TYPE_TAG_NAME has been an occasional source of confusion and bugs. It seems to me that it is only useful for C and C++ -- but even there, not so much, because at least with DWARF there doesn't seem to be any way to wind up with a type where the name and the tag name are both non-NULL and different. So, this patch removes TYPE_TAG_NAME entirely. This should save a little memory, but more importantly, it simplifies this part of gdb. A few minor test suite adjustments were needed.

2018-05-29Remove a VEC from type.cTom Tromey1-1/+1
This removes a VEC from type.c, by using std::vector. While doing this I also took the opportunity to change types_deeply_equal to return bool. This caught some weird code in typy_richcompare, now fixed. And, since I was changing types_deeply_equal, it seemed like a good idea to also change types_equal, so this patch includes that as well.

2018-05-04Use counted_command_line everywhereTom Tromey1-4/+4
Currently command lines are reference counted using shared_ptr only when attached to breakpoints. This patch changes gdb to use shared_ptr in commands as well. This allows for the removal of copy_command_lines. Note that the change to execute_user_command explicitly makes a new reference to the command line. This will be used in a later patch. This simplifies struct command_line based on the observation that a given command can have at most two child bodies: an "if" can have both "then" and "else" parts. Perhaps the names I've chosen for the replacements here are not very good -- your input requested.

2018-04-23Remove a cleanup from scm-frame.cTom Tromey1-29/+25
This removes a cleanup from scm-frame.c, replacing it with unique_xmalloc_ptr and a new scope. I believe this also fixes a latent bug involving calling do_cleanups twice for a single cleanup.

2018-04-06Introduce a gdb_ref_ptr specialization for struct valueTom Tromey1-3/+2
struct value is internally reference counted and so, while it also has some ownership rules unique to it, it makes sense to use a gdb_ref_ptr when managing it automatically. This patch removes the existing unique_ptr specialization in favor of a reference-counted pointer. It also introduces two other clarifications: 1. Rename value_free to value_decref, which I think is more in line with what the function actually does; and 2. Change release_value to return a gdb_ref_ptr. This change allows us to remove the confusing release_value_or_incref function, primarily by making it much simpler to reason about the result of release_value. gdb/ChangeLog 2018-04-06 Tom Tromey <tom@tromey.com> * varobj.c (varobj_clear_saved_item) (update_dynamic_varobj_children, install_new_value, ~varobj): Update. * value.h (value_incref): Move declaration earlier.

2018-03-19Convert observers to C++Tom Tromey1-3/+3
This converts observers from using a special source-generating script to be plain C++. This version of the patch takes advantage of C++11 by using std::function and variadic templates; incorporates Pedro's patches; and renames the header file to "observable.h" (this change eliminates the need for a clean rebuild). Note that Pedro's patches used a template lambda in tui-hooks.c, but this failed to compile on some buildbot instances (presumably due to differing C++ versions); I replaced this with an ordinary template function.

2018-02-28Create new common/pathstuff.[ch]Sergio Durigan Junior1-0/+1
This commit moves the path manipulation routines found on utils.c to a new common/pathstuff.c, and updates the Makefile.in's accordingly. The routines moved are "gdb_realpath", "gdb_realpath_keepfile" and "gdb_abspath". This will be needed because gdbserver will have to call "gdb_abspath" on my next patch, which implements a way to expand the path of the inferior provided by the user in order to allow specifying just the binary name when starting gdbserver, like: $ gdbserver :1234 a.out With the recent addition of the startup-with-shell feature on gdbserver, this scenario doesn't work anymore if the user doesn't have the current directory listed in the PATH variable. I had to do a minor adjustment on "gdb_abspath" because we don't have access to "tilde_expand" on gdbserver, so now the function is using "gdb_tilde_expand" instead. Otherwise, the code is the same. Regression tested on the BuildBot, without regressions. gdb/ChangeLog: 2018-02-28 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in (COMMON_SFILES): Add "common/pathstuff.c".

2017-11-29Make "break foo" find "A::foo", A::B::foo", etc. [C++ and wild matching]Pedro Alves1-2/+4
This patch teaches GDB about setting breakpoints in all scopes (namespaces and classes) by default. Here's a contrived example: (gdb) b func<tab> (anonymous namespace)::A::function() Bn::(anonymous namespace)::B::function() function(int, int) (anonymous namespace)::B::function() Bn::(anonymous namespace)::function() gdb::(anonymous namespace)::A::function() (anonymous namespace)::B::function() const Bn::(anonymous namespace)::function(int, int) gdb::(anonymous namespace)::function() (anonymous namespace)::function() Bn::B::func() gdb::(anonymous namespace)::function(int, int) (anonymous namespace)::function(int, int) Bn::B::function() gdb::A::func() A::func() Bn::func() gdb::A::function() A::function() Bn::function() gdb::func() B::func() Bn::function(int, int) gdb::function() B::function() Bn::function(long) gdb::function(int, int) B::function() const func() gdb::function(long) B::function_const() const function() (gdb) b function Breakpoint 1 at 0x4005ce: function. (26 locations) (gdb) b B::function<tab> (anonymous namespace)::B::function() B::function() const Bn::B::function() (anonymous namespace)::B::function() const B::function_const() const B::function() Bn::(anonymous namespace)::B::function() (gdb) b B::function Breakpoint 1 at 0x40072c: B::function. (6 locations) To get back the original behavior of interpreting the function name as a fully-qualified name, you can use the new "-qualified" (or "-q") option/flag (added by this commit). For example: (gdb) b B::function (anonymous namespace)::B::function() B::function() const Bn::B::function() (anonymous namespace)::B::function() const B::function_const() const B::function() Bn::(anonymous namespace)::B::function() vs: (gdb) b -qualified B::function B::function() B::function() const B::function_const() const I've chosen "-qualified" / "-q" because "-f" (for "full" or "fully-qualified") is already taken for "-function". Note: the "-qualified" option works with both linespecs and explicit locations. I.e., these are equivalent: (gdb) b -q func (gdb) b -q -f func and so are these: (gdb) b -q filename.cc:func (gdb) b -q -s filename.cc -f func (gdb) b -s filename.cc -q -f func (gdb) b -s filename.cc -f func -q To better understand why I consider wild matching the better default, consider what happens when we get to the point when _all_ of GDB is wrapped under "namespace gdb {}". I have a patch series that does that, and when I started debugging that GDB, I immediately became frustrated. You'd have to write "b gdb::internal_error", "b gdb::foo", "b gdb::bar", etc. etc., which gets annoying pretty quickly. OTOH, consider how this makes it very easy to set breakpoints in classes wrapped in anonymous namespaces. You just don't think of them, GDB finds the symbols for you automatically. (At the Cauldron a couple months ago, several people told me that they run into a similar issue when debugging other C++ projects. One example was when debugging LLVM, which puts all its code under the "llvm" namespace.) Implementation-wise, what the patch does is: - makes C++ symbol name hashing only consider the last component of a symbol name. (so that we can look up symbol names by last-component name only). - adds a C++ symbol name matcher for symbol_name_match_type::WILD, which ignores missing leading specifiers / components. - adjusts a few preexisting testsuite tests to use "-qualified" when they mean it. - adds new testsuite tests. - adds unit tests. Grows the gdb.linespec/ tests like this: -# of expected passes 7823 +# of expected passes 8977 gdb/ChangeLog: 2017-11-29 Pedro Alves <palves@redhat.com> * NEWS: Mention that breakpoints on C++ functions are now set on on all namespaces/classes by default, and mention "break -qualified". * ax-gdb.c (agent_command_1): Adjust to pass a symbol_name_match_type to new_linespec_location. * breakpoint.c (parse_breakpoint_sals): Adjust to get_linespec_location's return type change.

2017-11-06Target FP: Handle interfaces to scripting languagesUlrich Weigand2-8/+35
The last remaing use for DOUBLEST is in the code that interfaces to the scripting languages (Python and Guile). The problem here is that we expose interfaces to convert a GDB value to and from native values of floating-point type in those languages, and those by definition use the host floating-point format. While we cannot completely eliminate conversions to/from the host floating-point format here, we still need to get rid of the uses of value_as_double / value_from_double, since those will go away. This patch implements two new target-float.c routine: - target_float_to_host_double - target_float_from_host_double which convert to/from a host "double". Those should only ever be used where a host "double" is mandated by an external interface. gdb/ChangeLog: 2017-11-06 Ulrich Weigand <uweigand@de.ibm.com> * target-float.c (floatformat_to_host_double): New function.

2017-10-11Constify add_prefix_cmdTom Tromey1-3/+3
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.

This adds two add_cmd overloads: one whose callback takes a const char *, and one that doesn't accept a function at all.

I think it's a bit cleaner/safer to initialize address with a pessimistic value and assign it on success. Then there's no chance of using it uninitialized. If I understand correctly, the NULL check on res_val was to check whether value_addr threw, and that if value_addr returns without throwing, the result will never be NULL. If that's true, we can skip the res_val variable. Tested by running gdb.guile/*.exp locally. gdb/ChangeLog: * guile/scm-value.c (gdbscm_value_address): Initialize address, get rid of res_val.
