2024-03-26gdb, gdbserver, gdbsupport: remove includes of early headersSimon Marchi1-1/+0
Now that defs.h, server.h and common-defs.h are included via the `-include` option, it is no longer necessary for source files to include them. Remove all the inclusions of these files I could find. Update the generation scripts where relevant. Change-Id: Ia026cff269c1b7ae7386dd3619bc9bb6a5332837 Approved-By: Pedro Alves <pedro@palves.net>
2024-01-12Update copyright year range in header of all files managed by GDBAndrew Burgess1-1/+1
This commit is the result of the following actions: - Running gdb/copyright.py to update all of the copyright headers to include 2024, - Manually updating a few files the copyright.py script told me to update, these files had copyright headers embedded within the file, - Regenerating gdbsupport/Makefile.in to refresh it's copyright date, - Using grep to find other files that still mentioned 2023. If these files were updated last year from 2022 to 2023 then I've updated them this year to 2024. I'm sure I've probably missed some dates. Feel free to fix them up as you spot them.
2023-11-29Use C++17 [[fallthrough]] attributeTom Tromey1-1/+1
This changes gdb to use the C++17 [[fallthrough]] attribute rather than special comments. This was mostly done by script, but I neglected a few spellings and so also fixed it up by hand. I suspect this fixes the bug mentioned below, by switching to a standard approach that, presumably, clang supports.

2023-11-21gdb: Use C++17's std::make_unique instead of gdb::make_uniqueLancelot Six1-1/+1
gdb::make_unique is a wrapper around std::make_unique when compiled with C++17. Now that C++17 is required, use std::make_unique directly in the codebase, and remove gdb::make_unique.

2023-08-23gdb: add gdb::make_unique functionAndrew Burgess1-1/+1
While GDB is still C++11, lets add a gdb::make_unique template function that can be used to create std::unique_ptr objects, just like the C++14 std::make_unique. If GDB is being compiled with a C++14 compiler then the new gdb::make_unique function will delegate to the std::make_unique. I checked with gcc, and at -O1 and above gdb::make_unique will be optimised away completely in this case. If C++14 (or later) becomes our minimum, then it will be easy enough to go through the code and replace gdb::make_unique with std::make_unique later on. I've make use of this function in all the places I think this can easily be used, though I'm sure I've probably missed some. Should be no user visible changes after this commit.

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.

2022-03-29Unify gdb printf functionsTom Tromey1-25/+25
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.

2022-01-26gdb: add string_file::release methodSimon Marchi1-1/+1
A common pattern for string_file is to want to move out the internal string buffer, because it is the result of the computation that we want to return. It is the reason why string_file::string returns a non-const reference, as explained in the comment. I think it would make sense to have a dedicated method for that instead and make string_file::string return a const reference. This allows removing the explicit std::move in the typical case. Note that compile_program::compute was missing a move, meaning that the resulting string was copied. With the new version, it's not possible to forget to move.

2022-01-01Automatic Copyright Year update after running gdb/copyright.pyJoel Brobecker1-1/+1

2021-11-18gdbsupport: make gdb_assert_not_reached accept a format stringSimon Marchi1-3/+3
Change gdb_assert_not_reached to accept a format string plus corresponding arguments. This allows giving more precise messages. Because the format string passed by the caller is prepended with a "%s:" to add the function name, the callers can no longer pass a translated string (`_(...)`). Make the gdb_assert_not_reached include the _(), just like the gdb_assert_fail macro just above. Change-Id: Id0cfda5a57979df6cdaacaba0d55dd91ae9efee7

2021-01-23Use std::vector for "registers_used" in compile featureTom Tromey1-4/+4
This changes the GDB compile code to use std::vector<bool> when computing which registers are used.

2019-07-10Don't include gdbarch.h from defs.hTom Tromey1-0/+1
I touched symtab.h and was surprised to see how many files were rebuilt. I looked into it a bit, and found that defs.h includes gdbarch.h, which in turn includes many things. gdbarch.h is only needed by a minority ofthe files in gdb, so this patch removes the include from defs.h and updates the fallout. I did "wc -l" on the files in build/gdb/.deps; this patch reduces the line count from 139935 to 137030; so there are definitely future build-time savings here. Note that while I configured with --enable-targets=all, it's possible that some *-nat.c file needs an update. I could not test all of these. The buildbot caught a few problems along these lines. gdb/ChangeLog 2019-07-10 Tom Tromey <tom@tromey.com> * defs.h: Don't include gdbarch.h. * aarch64-ravenscar-thread.c, aarch64-tdep.c, alpha-bsd-tdep.h, alpha-linux-tdep.c, alpha-mdebug-tdep.c, arch-utils.h, arm-tdep.h, ax-general.c, btrace.c, buildsym-legacy.c, buildsym.h, c-lang.c, cli/cli-decode.h, cli/cli-dump.c, cli/cli-script.h, cli/cli-style.h, coff-pe-read.h, compile/compile-c-support.c, compile/compile-cplus.h, compile/compile-loc2c.c, corefile.c, cp-valprint.c, cris-linux-tdep.c, ctf.c, d-lang.c, d-namespace.c, dcache.c, dicos-tdep.c, dictionary.c, disasm-selftests.c, dummy-frame.c, dummy-frame.h, dwarf2-frame-tailcall.c, dwarf2expr.c, expression.h, f-lang.c, frame-base.c, frame-unwind.c, frv-linux-tdep.c, gdbarch-selftests.c, gdbtypes.h, go-lang.c, hppa-nbsd-tdep.c, hppa-obsd-tdep.c, i386-dicos-tdep.c, i386-tdep.h, ia64-vms-tdep.c, interps.h, language.c, linux-record.c, location.h, m2-lang.c, m32r-linux-tdep.c, mem-break.c, memattr.c, mn10300-linux-tdep.c, nios2-linux-tdep.c, objfiles.h, opencl-lang.c, or1k-linux-tdep.c, p-lang.c, parser-defs.h, ppc-tdep.h, probe.h, python/py-record-btrace.c, record-btrace.c, record.h, regcache-dump.c, regcache.h, riscv-fbsd-tdep.c, riscv-linux-tdep.c, rust-exp.y, sh-linux-tdep.c, sh-nbsd-tdep.c, source-cache.c, sparc-nbsd-tdep.c, sparc-obsd-tdep.c, sparc-ravenscar-thread.c, sparc64-fbsd-tdep.c, std-regs.c, target-descriptions.h, target-float.c, tic6x-linux-tdep.c, tilegx-linux-tdep.c, top.c, tracefile.c, trad-frame.c, type-stack.h, ui-style.c, utils.c, utils.h, valarith.c, valprint.c, varobj.c, x86-tdep.c, xml-support.h, xtensa-linux-tdep.c, cli/cli-cmds.h: Update. * s390-linux-nat.c, procfs.c, inf-ptrace.c: Likewise.
2019-07-09Rename common to gdbsupportTom Tromey1-2/+2
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.

2019-03-29Allow really large fortran array bounds: TYPE_LENGTH to ULONGESTKeith Seitz1-2/+2
This series is revisit of Siddhesh Poyarekar's patch from back in 2012. The last status on the patch is in the following gdb-patches thread: https://sourceware.org/ml/gdb-patches/2012-08/msg00562.html It appears that Tom approved the patch, but Jan had some issues with a compiler error that made the test fail on -m32 test runs. He wrote up a hand-tweaked .S file to deal with it. Siddesh said he would update tests. Then nothing. Siddesh and Jan have both moved on since. The patch originally required a large precursor patch to work. I have whittled this down to/rewritten the bare minimum, and this first patch is the result, changing the type of TYPE_LENGTH to ULONGEST from unsigned int. The majority of the changes involve changing printf format strings to use %s and pulongest instead of %d. gdb/ChangeLog: * ada-lang.c (ada_template_to_fixed_record_type_1): Use %s/pulongest for TYPE_LENGTH instead of %d in format strings. * ada-typerint.c (ada_print_type): Likewise. * amd64-windows-tdep.c (amd64_windows_store_arg_in_reg): Likewise. * compile/compile-c-support.c (generate_register_struct): Likewise. * gdbtypes.c (recursive_dump_type): Likewise. * gdbtypes.h (struct type) <length>: Change type to ULONGEST. * m2-typeprint.c (m2_array): Use %s/pulongest for TYPE_LENGTH instead of %d in format strings. * riscv-tdep.c (riscv_type_alignment): Cast second argument to std::min to ULONGEST. * symmisc.c (print_symbol): Use %s/pulongest for TYPE_LENGTH instead of %d in format strings. * tracepoint.c (info_scope_command): Likewise. * typeprint.c (print_offset_data::update) (print_offset_data::finish): Likewise. * xtensa-tdep.c (xtensa_store_return_value) (xtensa_push_dummy_call): Likewise.
2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
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.
2018-09-06compile: Remove non-const reference parametersSimon Marchi1-1/+1
As mentioned here: https://sourceware.org/gdb/wiki/Internals%20GDB-C-Coding-Standards#Avoid_non-const_reference_parameters.2C_use_pointers_instead we prefer to avoid non-const references. This patch changes the non-const references I could find in the compile/ directory, either by making them rvalue-reference (&&) or changing them to pointers. I'd say all the changes are pretty obvious, except the one in compile_cplus_instance::enter_scope which might require more attention. gdb/ChangeLog: * compile/compile-c.h (generate_c_for_variable_locations): Change reference to pointer. * compile/compile-c-support.c (compile_program) <compute>: Likewise. * compile/compile-c-symbols.c (generate_vla_size): Likewise.

2018-08-29C++ compile supportKeith Seitz1-25/+180
This patch adds *basic* support for C++ to the compile feature. It does most simple type conversions, including everything that C compile does and your basic "with-classes" type of C++. I've written a new compile-support.exp support file which adds a new test facility for automating and simplifying "compile print" vs "compile code" testing. See testsuite/lib/compile-support.exp and CompileExpression for more on that. The tests use this facility extensively. This initial support has several glaring omissions: - No template support at all I have follow-on patches for this, but they add much complexity to this "basic" support. Consequently, they will be submitted separately. - Cannot print functions The code template needs tweaking, and I simply haven't gotten to it yet. - So-called "special function" support is not included Using constructors, destructors, operators, etc will not work. I have follow-on patches for that, but they require some work because of the recent churn in symbol searching. - There are several test suite references to "compile/1234" bugs. I will file bugs and update the test suite's bug references before pushing these patches. The test suite started as a copy of the original C-language support, but I have written tests to exercise the basic functionality of the plug-in. I've added a new option for outputting debug messages for C++ type-conversion ("debug compile-cplus-types"). gdb/ChangeLog: * Makefile.in (SUBDIR_GCC_COMPILE_SRCS): Add compile-cplus-symbols.c and compile-cplus-types.c.

2018-08-10Use policies for code generationKeith Seitz1-157/+256
This patch changes code generation procedures add_code_header, add_code_footer, and several other language-specific code generation functions into policies. gdb/ChangeLog: * compile/compile-c-support.c (add_code_header, add_code_footer): Move into policy class.

(c_compute_porgram): Use c_compile_program.
2018-08-10Change compile_instance/compile_c_instance into classesKeith Seitz1-14/+15
This patch changes structs compile_instance and compile_c_instance into classes. Because of the nature of the change, there are a number of unavoidably mechanical changes buried in here, such as turning variable access of the POD struct into method calls, removing the struct keyword, and changing access of the plugin from "c_plugin->operation()" to "plugin ().operation ()". There is one "non-trivial" change associated with this patch, though. The type cache and symbol error maps have been moved into the base class, believing these facilities would be used other language implementations. [They are indeed re-used by C++.] gdb/ChangeLog: * compile/compile-c-support.c (c_get_compile_context): Use `new' instead of `new_compile_instance'. * compile/compile-c-symbols.c (compile_instance::insert_symbol_error): Update description. If the symbol error map is not initialized, create it. (generate_c_for_for_one_symbol): Do not check/initialize the symbol error map. * compile/compile-c-types.c (compile_c_instance): Make a class. Update all callers. (compile_instance::compile_instance): Initialize the type cache. (get_cached_type): New function. (insert_type): Update description.

2018-08-10Move C-related declarations to compile-c.hKeith Seitz1-0/+1
This patch simply moves a bunch of C language-related declarations from the various compile header files into a new C-specific header, compile-c.h. gdb/ChangeLog: * Makefile.in (SUBDIR_GCC_COMPILE_SRCS): Move header files ... (HFILES_NO_SRCDIR): ... to here. Add compile-internal.h and compile-c.h. * compile/compile-c-support.c: Include compile-c.h. * compile/compile-c-symbols.c: Include compile-c.h. (generate_c_for_variable_locations): Update comment. * compile/compile-c-types.c: Include compile-c.h. * compile/compile-c.h: New file -- moved C language declarations from other files here. * compile/compile-internal.h: Do not include hashtab.h or common/enum-flags.h.

2018-08-10Return unique_xmalloc_ptr for generate_c_for_variable_locationsKeith Seitz1-6/+4
This patch eliminates two cleanups in compile/ by changing generate_c_for_variable_locations so that it returns a unique_ptr. gdb/ChangeLog: * compile/compile-c-support.c (c_compute_program): Use unique_xmalloc_ptr to eliminate cleanup. * compile/compile-c-symbols.c (generate_c_for_variable_locations): Return a unique_xmalloc_ptr and eliminate cleanup. * compile/compile-internal.h (generate_c_for_variable_locations): Return unique_xmalloc_ptr and update description.
2018-02-08Return unique_xmalloc_ptr from macro scope functionsTom Tromey1-1/+1
This changes the macro scope functions (sal_macro_scope, user_macro_scope, and default_macro_scope) to return a unique_xmalloc_ptr, then fixes up the users.

2017-02-23Use gdb::function_view in iterate_over_symtabs & coPedro Alves1-4/+12
I wanted to pass a lambda to iterate_over_symtabs (see following patch), so I converted it to function_view, and then the rest is cascaded from that. This gets rid of a bunch of single-use callback functions and corresponding manually managed callback capture types (add_partial_datum, search_symbols_data, etc.) in favor of letting the compiler generate them for us by using lambdas with a capture. In a couple cases, it was more natural to convert the existing function callbacks to function objects (i.e., operator(), e.g., decode_compound_collector). gdb/ChangeLog: 2017-02-23 Pedro Alves <palves@redhat.com> * ada-lang.c: Include "common/function-view.h".

2017-02-02Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchyPedro Alves1-36/+26
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.

2016-11-08Use ui_file_as_string in gdb/compile/Pedro Alves1-3/+3
Using ui_file_as_string would imply changing a few prototypes to pass around source and object file names as std::string. Instead of that, wrap those two in a new class. This ends up eliminating a small wrinkle: get_new_file_names and compile_object_load have swapped parameters. The former takes "source, objfile", while the latter takes "objfile, source". gdb/ChangeLog: 2016-11-08 Pedro Alves <palves@redhat.com> * c-lang.h (c_compute_program): Now returns std::string. * compile/compile-internal.h (class compile_file_names): New class. * compile/compile-object-load.c (compile_object_load): Replace object_file and source_file parameters with a compile_file_names parameter. Adjust. * compile-object-load.h: Include "compile-internal.h". (compile_object_load): Replace object_file and source_file parameters with a compile_file_names parameter. * compile/compile-c-support.c (c_compute_program): Now returns a std::string. Use ui_file_as_string. * compile/compile.c (get_new_file_names): Remove parameters and return a compile_file_names instead. (compile_to_object): Now returns a compile_file_names.

2015-09-25Add some more casts (1/2)Simon Marchi1-1/+1
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).

2015-05-16compile: New 'compile print'Jan Kratochvil1-2/+42
It is planned the existing GDB command 'print' will be able to evaluate its expressions using the compiler. There will be some option to choose between the existing GDB evaluation and the compiler evaluation. But as an intermediate step this patch provides the expression printing feature as a new command. I can imagine it could be also called 'maintenance compile print' as in the future one should be able to use its functionality by the normal 'print' command. There was a discussion with Eli about the command name: https://sourceware.org/ml/gdb-patches/2015-03/msg00880.html As there were no other comments yet I haven't renamed it yet, before there is some confirmation about settlement on the final name.

2015-05-16compile: Use -Wall, not -wJan Kratochvil1-5/+7
For a reason unknown to me GDB was using -w instead of -Wall for 'compile code'. The problem is later patch for 'compile printf' really needs some warnings to be able to catch for example missing format string parameters: (gdb) compile printf "%d\n" GCC does not seem to be able to cancel -w (there is nothing like -no-w). Besides that I think even 'compile code' can benefit from -Wall. That #ifndef change in print_one_macro() is needed otherwise we get macro-redefinition warnings for the GCC built-in macros (as -w is no longer in effect). For example, without the #ifndef/#endif one gets: compile -r -- void _gdb_expr(){int i = 5;}^M /tmp/gdbobj-xpU1yB/out4.c:4:0: warning: "__FILE__" redefined [-Wbuiltin-macro-redefined]^M /tmp/gdbobj-xpU1yB/out4.c:5:0: warning: "__LINE__" redefined^M ... It makes more sense to pick the inferior's version of the macros, hence #ifndef instead of #undef. That new testsuite XFAIL is there as if one changes the struct definition to be compliant with cv-qualifiers (to prevent the warnings): struct struct_type { - struct struct_type *selffield; + volatile struct struct_type *selffield; only then GCC/GDB will hit the crash, described in that GDB PR 18202. gdb/ChangeLog 2015-05-16 Jan Kratochvil <jan.kratochvil@redhat.com> * compile/compile-c-support.c (print_one_macro): Use #ifndef.

2014-12-12the "compile" commandTom Tromey1-0/+399
This final patch adds the new "compile" command and subcommands, and all the machinery needed to make it work. A shared library supplied by gcc is used for all communications with gcc. Types and most aspects of symbols are provided directly by gdb to the compiler using this library. gdb provides some information about the user's code using plain text. Macros are emitted this way, and DWARF location expressions (and bounds for VLA) are compiled to C code. This hybrid approach was taken because, on the one hand, it is better to provide global declarations and such on demand; but on the other hand, for local variables, translating DWARF location expressions to C was much simpler than exporting a full compiler API to gdb -- the same result, only easier to implement, understand, and debug. In the ordinary mode, the user's expression is wrapped in a dummy function. After compilation, gdb inserts the resulting object code into the inferior, then calls this function. Access to local variables is provided by noting which registers are used by location expressions, and passing a structure of register values into the function. Writes to registers are supported by copying out these values after the function returns. This approach was taken so that we could eventually implement other more interesting features based on this same infrastructure; for example, we're planning to investigate inferior-side breakpoint conditions. gdb/ChangeLog 2014-12-12 Phil Muldoon <pmuldoon@redhat.com> Jan Kratochvil <jan.kratochvil@redhat.com> Tom Tromey <tromey@redhat.com> * NEWS: Update. * symtab.h (struct symbol_computed_ops) <generate_c_location>: New field. * p-lang.c (pascal_language_defn): Update. * opencl-lang.c (opencl_language_defn): Update. * objc-lang.c (objc_language_defn): Update. * m2-lang.c (m2_language_defn): Update. * language.h (struct language_defn) <la_get_compile_instance, la_compute_program>: New fields. * language.c (unknown_language_defn, auto_language_defn) (local_language_defn): Update. * jv-lang.c (java_language_defn): Update. * go-lang.c (go_language_defn): Update. * f-lang.c (f_language_defn): Update. * dwarf2loc.h (dwarf2_compile_property_to_c): Declare. * dwarf2loc.c (dwarf2_compile_property_to_c) (locexpr_generate_c_location, loclist_generate_c_location): New functions.
