2023-04-27gdb: remove some trailing newlines from warning messagesAndrew Burgess1-4/+4
While working on a later patch in this series, which tightens up some of our pattern matching when using gdb_test, I ran into some failures caused by some warnings having a trailing newline character. The warning function already adds a trailing newline, and it is my understanding that we should not be adding a second by including a newline at the end of any warning message. The problem cases I found were in language.c and remote.c, in this patch I fix the cases I hit, but I also checked all the other warning calls in these two files and removed any additional trailing newlines I found. In remote.c the warning actually had a newline character in the middle of the warning message (in addition to the trailing newline), which I've removed. I don't think it's helpful to forcibly split a warning as was done here -- in the middle of a sentence. Additionally, the message isn't even that long (71 characters), so I think removing this newline is an improvement. None of the expected test result need updating with this commit, currently the patterns in gdb_test will match one or more newline sequences, so the tests are as happy with one newline (after this commit) as they are with two newlines (before this commit). A later commit will change gdb_test so that it is not so forgiving, and these warnings would have caused some failures. Reviewed-By: Tom Tromey <tom@tromey.com>
2023-04-21gdb: remove language_autoSimon Marchi1-92/+43
I think that the language_auto enumerator and the auto_language class can be removed. There isn't really an "auto" language, it's only a construct of the "set language" command to say "pick the appropriate language automatically". But "auto" is never the current language. The `current_language` points to the current effective language, and the fact that we're in "auto language" mode is noted by the language_mode global. - Change set_language to handle the "auto" (and "local", which is a synonym) early, instead of in the for loop. I think it makes the two cases (auto vs explicit language) more clearly separated anyway. - Adjust add_set_language_command to hard-code the "auto" string, instead of using the "auto" language definition. - Remove auto_language, rename auto_or_unknown_language to unknown_language and move the bits of the existing unknown_language in there. - Remove the set_language at the end of _initialize_language. I think it's not needed, because we call set_language in gdb_init, after all _initialize functions are called. There is some chance that an _initialize function that runs after _initialize_language implicitly depends on current_language being set, but my testsuite runs haven't found anything like that. - Use language_unknown instead of language_auto when creating a minimal symbol (minimal_symbol_reader::record_full). I think that this value is used to indicate that we don't know the symbol of the minimal symbol (yet), so language_unknown makes sense to me. Update a condition accordingly in ada-lang.c. symbol_find_demangled_name also appears to "normalize" this value from "unknown" to "auto", remove that part and update the condition to just check for language_unknown.

2023-04-21gdb: switch "set language" to getter/setterSimon Marchi1-9/+19
The `language` global variable is mostly a scratch variable used for the setting. The source of truth is really current_language and language_mode (auto vs manual), which are set by the set_language_command callback. Switch the setting to use the add_setshow_enum_cmd overload that takes a value getter and setter. Change-Id: Ief5b2f93fd7337eed7ec96023639ae3dfe62250b Reviewed-By: Tom Tromey <tom@tromey.com>

2023-03-31Remove language_demangleTom Tromey1-15/+0
I noticed that language_demangle shadows the global "current_language". When I went to fix this, though, I then saw that language_demangle is only called in two places, and has a comment saying it should be removed. This patch removes it. Note that the NULL check in language_demangle is not needed by either of the existing callers. Regression tested on x86-64 Fedora 36. Approved-By: Simon Marchi <simon.marchi@efficios.com>
2023-01-20gdb: move compile_instance to compile/compile.hSimon Marchi1-1/+0
struct compile_instance needs to be visible to users, since we use std::unique<compile_instance>. language.c and c-lang.c currently includes compile-internal.h for this reason, which kind of defeats the purpose of having an "internal" header file.

Convert the implementation of 'set debug symbol-lookup' to the new debug printing scheme. In a few places I've updated the debug output to remove places where the printed debug message included the function name, the new debug scheme already adds that, but I haven't done all the possible updates.
2022-10-19internal_error: remove need to pass __FILE__/__LINE__Pedro Alves1-11/+6
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.

2022-08-04Use registry in gdbarchTom Tromey1-21/+18
gdbarch implements its own registry-like approach. This patch changes it to instead use registry.h. It's a rather large patch but largely uninteresting -- it's mostly a straightforward conversion from the old approach to the new one. The main benefit of this change is that it introduces type safety to the gdbarch registry. It also removes a bunch of code. One possible drawback is that, previously, the gdbarch registry differentiated between pre- and post-initialization setup. This doesn't seem very important to me, though.

2022-01-26Fix another crash with gdb parameters in PythonTom Tromey1-5/+6
While looking into the language-capturing issue, I found another way to crash gdb using parameters from Python: (gdb) python print(gdb.parameter('endian')) (This is related to PR python/12188, though this patch isn't going to fix what that bug is really about.) The problem here is that the global variable that underlies the "endian" parameter is initialized to NULL. However, that's not a valid value for an "enum" set/show parameter. My understanding is that, in gdb, an "enum" parameter's underlying variable must have a value that is "==" (not just strcmp-equal) to one of the values coming from the enum array. This invariant is relied on in various places. I started this patch by fixing the problem with "endian". Then I added some assertions to add_setshow_enum_cmd to try to catch other problems of the same type. This patch fixes all the problems that I found. I also looked at all the calls to add_setshow_enum_cmd to ensure that they were all included in the gdb I tested. I think they are: there are no calls in nat-* files, or in remote-sim.c; and I was trying a build with all targets, Python, and Guile enabled.

2022-01-06Avoid crash in language_infoTom Tromey1-1/+1
language_info calls: show_language_command (NULL, 1, NULL, NULL); ... "knowing" that show_language_command does not use its ui_file parameter. However, this was changed in commit 7514a661 ("Consistently Use ui_file parameter to show callbacks"). This patch changes language_info to pass a ui_file. It took a while to write the test -- this function is only called when 'verbose' is on and when switching the "expected" language in auto mode.
2022-01-05Use filtered output in language_infoTom Tromey1-1/+1
Change language_info to use filtered output. This is ok because the sole caller uses filtered output elsewhere, and because this function calls show_language_command, which also uses filtered output.

2021-10-04Use unique_xmalloc_ptr<char> when demanglingTom Tromey1-2/+3
I noticed that some methods in language_defn could use unique_xmalloc_ptr<char> rather than a plain 'char *'. This patch implements this change, fixing up the fallout and changing gdb_demangle to also return this type. In one spot, std::string is used to simplify some related code, and in another, an auto_obstack is used to avoid manual management. Regression tested on x86-64 Fedora 34.
2021-09-24Move value_true to value.hTom Tromey1-17/+0
I noticed that value_true is declared in language.h and defined in language.c. However, as part of the value API, I think it would be better in one of those files. And, because it is very short, I changed it to be an inline function in value.h. I've also removed a comment from the implementation, on the basis that it seems obsolete -- if the change it suggests was needed, it probably would have been done by now; and if it is needed in the future, odds are it would be done differently anyway. Finally, this patch also changes value_true and value_logical_not to return a bool, and updates some uses.
2021-09-23Change pointer_type to a method of struct typeTom Tromey1-8/+0
I noticed that pointer_type is declared in language.h and defined in language.c. However, it really has to do with types, so it should have been in gdbtypes.h all along. This patch changes it to be a method on struct type. And, I went through uses of TYPE_IS_REFERENCE and updated many spots to use the new method as well. (I didn't update ones that were in arch-specific code, as I couldn't readily test that.)
2021-07-15Avoid expression parsing crash with unknown languageTom Tromey1-2/+2
PR gdb/28093 points out that gdb crashes when language is set to "unknown" and expression parsing is attempted. At first I thought this was a regression due to the expression rewrite, but it turns out that older versions crash as well. This patch avoids the crash by changing the default expression parser to throw an exception. I think this is preferable -- the current behavior of silently doing nothing does not really make sense.

2021-05-12gdb: generate the prefix name for prefix commands on demandMarco Barisione1-2/+2
Previously, the prefixname field of struct cmd_list_element was manually set for prefix commands. This seems verbose and error prone as it required every single call to functions adding prefix commands to specify the prefix name while the same information can be easily generated. Historically, this was not possible as the prefix field was null for many commands, but this was fixed in commit 3f4d92ebdf7f848b5ccc9e8d8e8514c64fde1183 by Philippe Waroquiers, so we can rely on the prefix field being set when generating the prefix name. This commit also fixes a use after free in this scenario: * A command gets created via Python (using the gdb.Command class). The prefix name member is dynamically allocated. * An alias to the new command is created. The alias's prefixname is set to point to the prefixname for the original command with a direct assignment. * A new command with the same name as the Python command is created. * The object for the original Python command gets freed and its prefixname gets freed as well. * The alias is updated to point to the new command, but its prefixname is not updated so it keeps pointing to the freed one. gdb/ChangeLog: * command.h (add_prefix_cmd): Remove the prefixname argument as it can now be generated automatically.

2021-01-28gdb: rename type::{arch,objfile} -> type::{arch_owner,objfile_owner}Simon Marchi1-1/+1
I think this makes the names of the methods clearer, especially for the arch. The type::arch method (which gets the arch owner, or NULL if the type is not arch owned) is easily confused with the get_type_arch method (which returns an arch no matter what). The name "arch_owner" will make it intuitive that the method returns NULL if the type is not arch-owned. Also, this frees the type::arch name, so we will be able to morph the get_type_arch function into the type::arch method. gdb/ChangeLog: * gdbtypes.h (struct type) <arch>: Rename to... <arch_owner>: ... this, update all users. <objfile>: Rename to... <objfile_owner>: ... this, update all users.

2021-01-22gdb: add owner-related methods to struct typeSimon Marchi1-1/+1
Add the following methods to struct type: * is_objfile_owned * set_owner (objfile and gdbarch overloads) * objfile and arch getters Rename the fields in main_type to ensure no other code accesses them directly. As usual, we can't make them actually private, but giving them the `m_` prefix will help making sure they are not accessed when not supposed to, by convention. Remove the TYPE_OWNER macro to ensure no code uses the type_owner struct directly. gdb/ChangeLog: * gdbtypes.h (TYPE_OBJFILE_OWNED): Adjust. (TYPE_OWNER): Remove. (TYPE_OBJFILE): Adjust.

2020-11-12gdb: rewrite how per language primitive types are managedAndrew Burgess1-100/+105
Consider the following GDB session: $ gdb (gdb) set language c (gdb) ptype void type = void (gdb) set language fortran (gdb) ptype void No symbol table is loaded. Use the "file" command. (gdb) With no symbol file loaded GDB and the language set to C GDB knows about the type void, while when the language is set to Fortran GDB doesn't know about the void, why is that? In f-lang.c, f_language::language_arch_info, we do have this line: lai->primitive_type_vector [f_primitive_type_void] = builtin->builtin_void; where we add the void type to the list of primitive types that GDB should always know about, so what's going wrong? It turns out that the primitive types are stored in a C style array, indexed by an enum, so Fortran uses `enum f_primitive_types'. The array is allocated and populated in each languages language_arch_info member function. The array is allocated with an extra entry at the end which is left as a NULL value, and this indicates the end of the array of types. Unfortunately for Fortran, a type is not assigned for each element in the enum. As a result the final populated array has gaps in it, gaps which are initialised to NULL, and so every time we iterate over the list (for Fortran) we stop early, and never reach the void type. This has been the case since 2007 when this functionality was added to GDB in commit cad351d11d6c3f6487cd. Obviously I could just fix Fortran by ensuring that either the enum is trimmed, or we create types for the missing types. However, I think a better approach would be to move to C++ data structures and removed the fixed enum indexing into the array approach. After this commit the primitive types are pushed into a vector, and GDB just iterates over the vector in the obvious way when it needs to hunt for a type. After this commit all the currently defined primitive types can be found when the language is set to Fortran, for example: $ gdb (gdb) set language fortran (gdb) ptype void type = void (gdb) A new test checks this functionality. I didn't see any other languages with similar issues, but I could have missed something. gdb/ChangeLog: * ada-exp.y (find_primitive_type): Make parameter const. * ada-lang.c (enum ada_primitive_types): Delete.

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-2/+2
Many spots incorrectly use only spaces for indentation (for example, there are a lot of spots in ada-lang.c). I've always found it awkward when I needed to edit one of these spots: do I keep the original wrong indentation, or do I fix it? What if the lines around it are also wrong, do I fix them too? I probably don't want to fix them in the same patch, to avoid adding noise to my patch. So I propose to fix as much as possible once and for all (hopefully). One typical counter argument for this is that it makes code archeology more difficult, because git-blame will show this commit as the last change for these lines. My counter counter argument is: when git-blaming, you often need to do "blame the file at the parent commit" anyway, to go past some other refactor that touched the line you are interested in, but is not the change you are looking for. So you already need a somewhat efficient way to do this. Using some interactive tool, rather than plain git-blame, makes this trivial. For example, I use "tig blame <file>", where going back past the commit that changed the currently selected line is one keystroke. It looks like Magit in Emacs does it too (though I've never used it). Web viewers of Github and Gitlab do it too. My point is that it won't really make archeology more difficult. The other typical counter argument is that it will cause conflicts with existing patches. That's true... but it's a one time cost, and those are not conflicts that are difficult to resolve. I have also tried "git rebase --ignore-whitespace", it seems to work well. Although that will re-introduce the faulty indentation, so one needs to take care of fixing the indentation in the patch after that (which is easy). gdb/ChangeLog: * aarch64-linux-tdep.c: Fix

2020-10-23gdb: remove LA_VALUE_PRINT macroAndrew Burgess1-1/+1
Remove the LA_VALUE_PRINT macro, and replace its uses with direct calls to the value_print member function on an appropriate language. In the global 'value_print' function, we call the value_print method on the current_language, this is a direct inline replacement of the old LA_VALUE_PRINT macro. However, in ada-lang.c, and language.c the macro was being used within the print_array_index member function of a language class. In these cases we now call the value_print member function of the current language class. In theory, when we are inside (for example) the ada_language::print_array_index function the current_language should always be set to Ada, so this change should have no effect. However, if we ever could get into ada_language::print_array_index with the current language set to something else (which I think would have been a bug) then we would now see a change in behaviour. I couldn't find any cases where this happened though. There should be no user visible changes after this commit, but it is not impossible in some edge cases. gdb/ChangeLog: * ada-lang.c (ada_language::print_array_index): Call value_print directly. * language.c (language_defn::print_array_index): Likewise. * language.h (LA_VALUE_PRINT): Delete. * valprint.c (value_print): Call value_print on the current_language directly.
2020-10-23gdb: Merge auto and unknown language implementationsAndrew Burgess1-155/+60
The auto_language and unknown_language classes are basically the same except for the language names and store_sym_names_in_linkage_form_p which the unknown_language overrides to return true, while auto_language returns the default false. This commit creates a new parent class from which both of these languages can inherit. The two base classes are now greatly reduced. Some of the static helper functions which previously were called from both of these languages are now only called from one place, and so I've inlined them into the new class. There should be no user visible changes after this commit. gdb/ChangeLog: * language.c (default_is_string_type_p): Delete, implementation moved into auto_or_unknown_language::is_string_type_p. (unk_op_print_tab): Moved into auto_or_unknown_language::opcode_print_table. (unknown_language_arch_info): Delete, implementation moved into auto_or_unknown_language::language_arch_info. (class auto_or_unknown_language): New class, member functions copied from unknown_language class, with some updates. (class unknown_language): Most member functions moved into auto_or_unknown_language class. Inherit from auto_or_unknown_language class. (class auto_language): Inherit from auto_or_unknown_language. Delete most member functions.
