2020-06-17gdb: Convert language la_get_symbol_name_matcher field to a methodAndrew Burgess1-1/+0
This commit changes the language_data::la_get_symbol_name_matcher function pointer member variable into a member function of language_defn. There should be no user visible changes after this commit. Before this commit access to the la_get_symbol_name_matcher function pointer was through the get_symbol_name_matcher function, which looked something like this (is pseudo-code): <return-type> get_symbol_name_matcher (language_defn *lang, <other args>) { if (current_language == ada) current_language->la_get_symbol_name_matcher (<other args>); else lang->la_get_symbol_name_matcher (<other args>); } In this commit I moved the get_symbol_name_matcher as a non-virtual function in the language_defn base class, I then add a new virtual method that is only used from within get_symbol_name_matcher, this can then be overridden by specific languages as needed. So we now have: class language_defn { <return-type> get_symbol_name_matcher (<args>) { if (current_language == ada) return current_language->get_symbol_name_matcher_inner (<args>); else return this->get_symbol_name_matcher_inner (<args>); } virtual <return-type> get_symbol_name_matcher_inner (<args>) { .... } } gdb/ChangeLog: * ada-lang.c (ada_get_symbol_name_matcher): Update header comment.

This commit changes the language_data::la_sniff_from_mangled_name function pointer member variable into a member function of language_defn. Previously the la_sniff_from_mangled_name pointer was NULL for some languages, however, all uses of this function pointer were through the function language_sniff_from_mangled_name which provided a default implementation.

This commit changes the language_data::la_read_var_value function pointer member variable into a member function of language_defn. An interesting aspect of this change is that the implementation of language_defn::read_var_value is actually in findvar.c. This is partly historical, the new language_defn::read_var_value is a rename of default_read_var_value, which was already in that file, but also, that is the file that contains the helper functions needed by the read_var_value method, so it makes sens that the method implementation should continue to live there (I think).

2020-06-02gdb: Represent all languages as sub-classes of language_defnAndrew Burgess1-1/+17
This commit converts all languages to sub-classes of a language_defn base class. The motivation for this change is to make it easier to add new methods onto languages without having to update all of the individual language structures. In the future it might be possible to move more things, like expression parsing, into the language class(es) for better encapsulation, however I have no plans to tackle this in the short term. This commit sets up a strategy for transitioning from the current language system, where each language is an instance of the language_defn structure, to the class hierarchy system. The plan is to rename the existing language_defn into language_data, and make this a base class for the new language_defn class, something like this: struct language_data { ... old language_defn fields here ... }; struct language_defn : public language_data { language_defn (const language_data d) : language_data (d) { .... } }; Then each existing language, for example ada_language_defn can be converted into an instance of language_data, and passed into the constructor of a new language class, something like this: language_data ada_language_data = { ... old ada_language_defn values here ... }; struct ada_language : public language_defn { ada_language (ada_language_data) { .... } }; What this means is that immediately after the conversion nothing much changes. Every language is now its own class, but all the old language fields still exist and can be accessed in the same way. In later commits I will convert function pointers from the old language_defn structure into real class methods on language_defn, with overrides on sub-classes where needed. At this point I imagine that those fields of the old language_defn structure that contained only data will probably remain as data fields within the new language_data base structure, it is only the methods that I plan to change initially. I tweaked how we manage the list of languages a bit, each language is now registered as it is created, and this resulted in a small number of changes in language.c. Most of the changes in the *-lang.c files are identical. There should be no user visible changes after this commit. gdb/ChangeLog: * gdb/ada-lang.c (ada_language_defn): Convert to...

The plan for removing val_print is, essentially, to first duplicate printing code as needed to use the value API; and then remove the val_print code. This makes it possible to do the changes incrementally while keeping everything working. This adds a new la_value_print_inner function pointer to struct language_defn. Eventually this will replace la_val_print. This patch also changes printing to prefer this API, when available -- but no language defines it yet. gdb/ChangeLog 2020-03-13 Tom Tromey <tom@tromey.com> * valprint.c (do_val_print): Call la_value_print_inner, if available. * rust-lang.c (rust_language_defn): Update. * 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_value_print_inner>: New member. * language.c (unknown_language_defn, auto_language_defn): Update. * go-lang.c (go_language_defn): Update. * f-lang.c (f_language_defn): Update. * d-lang.c (d_language_defn): Update. * c-lang.c (c_language_defn, cplus_language_defn) (asm_language_defn, minimal_language_defn): Update. * ada-lang.c (ada_language_defn): Update.

2019-11-21Adjust byte order variable display/change if DW_AT_endianity is present.Peeter Joot1-1/+1
- Rationale: It is possible for compilers to indicate the desired byte order interpretation of scalar variables using the DWARF attribute: DW_AT_endianity A type flagged with this variable would typically use one of: DW_END_big DW_END_little which instructs the debugger what the desired byte order interpretation of the variable should be. The GCC compiler (as of V6) has a mechanism for setting the desired byte ordering of the fields within a structure or union. For, example, on a little endian target, a structure declared as: struct big { int v; short a[4]; } __attribute__( ( scalar_storage_order( "big-endian" ) ) ); could be used to ensure all the structure members have a big-endian interpretation (the compiler would automatically insert byte swap instructions before and after respective store and load instructions). - To reproduce GCC V8 is required to correctly emit DW_AT_endianity DWARF attributes in all situations when the scalar_storage_order attribute is used. A fix for (dwarf endianity instrumentation) for GCC V6-V7 can be found in the URL field of the following PR: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82509 - Test-case: A new test case (testsuite/gdb.base/endianity.*) is included with this patch. Manual testing for mixed endianity code has also been done with GCC V8. See: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=82509#c4 - Observed vs. expected: Without this change, using scalar_storage_order that doesn't match the target, such as struct otherendian { int v; } __attribute__( ( scalar_storage_order( "big-endian" ) ) ); would behave like the following on a little endian target: Breakpoint 1 at 0x401135: file endianity.c, line 41.

2019-10-01Introduce metadata styleTom Tromey1-1/+4
This introduces a new "metadata" style and changes many places in gdb to use it. The idea here is to let the user distinguish gdb output from output that (conceptually at least) comes directly from the inferior. The newly-styled category includes text that gdb traditionally surrounds in "<...>", like "<unavailable>". I only added a single test for this. In many cases this output is difficult to test.

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.

2019-04-29gdb: Introduce new language field la_is_string_type_pAndrew Burgess1-0/+11
This commit is preparation work for the next commit, and by itself makes no user visible change to GDB. I've split this work into a separate commit in order to make code review easier. This commit adds a new field 'la_is_string_type_p' to the language struct, this predicate will return true if a type is a string type for the given language. Some languages already have a "is this a string" predicate that I was able to reuse, while for other languages I've had to add a new predicate. In this case I took inspiration from the value printing code for that language - what different conditions would result in printing something as a string. A default "is this a string" method has also been added that looks for TYPE_CODE_STRING, this is the fallback I've used for a couple of languages. In this commit I add the new field and initialise it for each language, however at this stage the new field is never used. gdb/ChangeLog: * ada-lang.c (ada_language_defn): Initialise new field. * c-lang.c (c_is_string_type_p): New function.

2019-04-12gdb: Remove LANG_MAGICAndrew Burgess1-2/+1
The language_defn structure has an la_magic field, this used to be used as a basic check that the language_defn structure had the expected layout - at least the end of the structure was where we expected it to be. This feature only really makes sense if we imagine GDB dynamically loading language support from dynamic libraries, where a version mismatch might cause problems. However, in current GDB language support is statically built into GDB, and since this commit: commit 47e77640be31fc1a4eb3718f594ed5fd0faff065 Date: Thu Jul 20 18:28:01 2017 +0100 Make language_def O(1) the existing (if pointless) check of the la_magic field was removed. There now appears to be no use of the la_magic field, and I propose that we delete it. There should be no user visible changes after this commit. gdb/ChangeLog: * ada-lang.c (ada_language_defn): Remove use of LANG_MAGIC. * c-lang.c (c_language_defn): Likewise.

2018-06-18Remove la_errorTom Tromey1-1/+0
While working on the parser code, I noticed that yyerror is exported from each parser. It is used by this code in parse.c: TRY { if (lang->la_parser (&ps)) lang->la_error (NULL); } However, it seems to me that la_error will never be called here, because in every case, la_parser throws an exception on error -- each implementation of yyerror just calls error. So, this patch removes la_error and makes all the yyerror functions static. This is handy primarily because it makes it simpler to make the expression parsers pure.

2018-03-27problem looking up some symbols when they have a linkage nameJoel Brobecker1-0/+1
This patch fixes a known failure in gdb.ada/maint_with_ada.exp (maintenance check-psymtabs). Another way to witness the same issue is by considering the following Ada declarations... type Wrapper is record A : Integer; end record; u00045 : constant Wrapper := (A => 16#060287af#); pragma Export (C, u00045, "symada__cS"); ... which declares a variable name "u00045" but with a linkage name which is "symada__cS". This variable is a record with one component, the Ada equivalent of a struct with one field in C. Trying to print that variable's value currently yields: (gdb) p /x <symada__cS> 'symada(char, signed)' has unknown type; cast it to its declared type This indicates that GDB was only able to find the minimal symbol, but not the full symbol. The expected output is: (gdb) print /x <symada__cS> $1 = (a => 0x60287af) The error message gives a hint about what's happening: We processed the symbol through gdb_demangle, which in the case of this particular symbol name, ends up matching the C++ naming scheme. As a result, the demangler transforms our symbol name into 'symada(char, signed)', thus breaking Ada lookups. This patch fixes the issue by first introducing a new language_defn attribute called la_store_sym_names_in_linkage_form_p, which is a boolean to be set to true for the few languages that do not want their symbols to have their names stored in demangled form, and false otherwise. We then use this language attribute to skip the call to gdb_demangle for all languages whose la_store_sym_names_in_linkage_form_p is true. In terms of the selection of languages for which the new attribute is set to true, the selection errs on the side of preserving the existing behavior, and only changes the behavior for the languages where we are certain storing symbol names in demangling form is not needed. It is conceivable that other languages might be in the same situation, but I not knowing in detail the symbol name enconding strategy, I decided to play it safe and let other language maintainers potentially adjust their language if it makes sense to do so. gdb/ChangeLog: PR gdb/22670 * dwarf2read.c (dwarf2_physname): Do not return the demangled symbol name if the CU's language stores symbol names in linkage format. * language.h (struct language_defn) <la_store_sym_names_in_linkage_form_p>: New field.

gdb/ChangeLog: Update copyright year range in all GDB files
2017-11-08Introduce lookup_name_info and generalize Ada's FULL/WILD name matchingPedro Alves1-1/+1
Summary: - This is preparation for supporting wild name matching on C++ too. - This is also preparation for TAB-completion fixes. - Makes symbol name matching (think strcmp_iw) be based on a per-language method. - Merges completion and non-completion name comparison (think language_ops::la_get_symbol_name_cmp generalized). - Avoid re-hashing lookup name multiple times - Centralizes preparing a name for lookup (Ada name encoding / C++ Demangling), both completion and non-completion. - Fixes Ada latent bug with verbatim name matches in expressions - Makes ada-lang.c use common|symtab.c completion code a bit more. Ada's wild matching basically means that "(gdb) break foo" will find all methods named "foo" in all packages. Translating to C++, it's roughly the same as saying that "break klass::method" sets breakpoints on all "klass::method" methods of all classes, no matter the namespace. A following patch will teach GDB about fullname vs wild matching for C++ too. This patch is preparatory work to get there. Another idea here is to do symbol name matching based on the symbol language's algorithm. I.e., avoid dependency on current language set. This allows for example doing (gdb) b foo::bar< int > (<tab> and having gdb name match the C++ symbols correctly even if the current language is C or Assembly (or Rust, or Ada, or ...), which can easily happen if you step into an Assembly/C runtime library frame. By encapsulating all the information related to a lookup name in a class, we can also cache hash computation for a given language in the lookup name object, to avoid recomputing it over and over. Similarly, because we don't really know upfront which languages the lookup name will be matched against, for each language we store the lookup name transformed into a search name. E.g., for C++, that means demangling the name. But for Ada, it means encoding the name. This actually forces us to centralize all the different lookup name encoding in a central place, resulting in clearer code, IMO. See e.g., the new ada_lookup_name_info class. The lookup name -> symbol search name computation is also done only once per language. The old language->la_get_symbol_name_cmp / symbol_name_cmp_ftype are generalized to work with both completion, and normal symbol look up. At some point early on, I had separate completion vs non-completion language vector entry points, but a single method ends up being better IMO for simplifying things -- the more we merge the completion / non-completion name lookup code paths, the less changes for bugs causing completion vs normal lookup finding different symbols. The ada-lex.l change is necessary because when doing (gdb) p <UpperCase> then the name that is passed to write_ write_var_or_type -> ada_lookup_symbol_list misses the "<>", i.e., it's just "UpperCase", and we end up doing a wild match against "UpperCase" lowercased by ada_lookup_name_info's constructor. I.e., "uppercase" wouldn't ever match "UpperCase", and the symbol lookup fails. This wouldn't cause any regression in the testsuite, but I added a new test that would pass before the patch and fail after, if it weren't for that fix. This is latent bug that happens to go unnoticed because that particular path was inconsistent with the rest of Ada symbol lookup by not lowercasing the lookup name. Ada's symbol_completion_add is deleted, replaced by using common code's completion_list_add_name. To make the latter work for Ada, we needed to add a new output parameter, because Ada wants to return back a custom completion candidates that are not the symbol name. With this patch, minimal symbol demangled name hashing is made consistent with regular symbol hashing. I.e., it now goes via the language vector's search_name_hash method too, as I had suggested in a previous patch. dw2_expand_symtabs_matching / .gdb_index symbol names were a challenge. The problem is that we have no way to telling what is the language of each symbol name found in the index, until we expand the corresponding full symbol, which is off course what we're trying to avoid. Language information is simply not considered in the index format... Since the symbol name hashing and comparison routines are per-language, we now have a problem. The patch sorts this out by matching each name against all languages. This is inneficient, and indeed slows down completion several times. E.g., with: $ cat script.cmd set pagination off set $count = 0 while $count < 400 complete b string_prin printf "count = %d\n", $count set $count = $count + 1 end $ time gdb --batch -q ./gdb-with-index -ex "source script-string_printf.cmd" I get, before patch (-O2, x86-64): real 0m1.773s user 0m1.737s sys 0m0.040s While after patch (-O2, x86-64): real 0m9.843s user 0m9.482s sys 0m0.034s However, the following patch will optimize this, and will actually make this use case faster compared to the "before patch" above: real 0m1.321s user 0m1.285s sys 0m0.039s gdb/ChangeLog: 2017-11-08 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_encode): Rename to ..

2017-11-08Per-language symbol name hashing algorithmPedro Alves1-0/+1
Currently, we have a mess of symbol name hashing/comparison routines. There's msymbol_hash for mangled names, and dict_hash and msymbol_hash_iw for demangled names. Then there's strcmp_iw, strcmp_iw_ordered and Ada's full_match/wild_match, which all have to agree with the hashing routines. That's why dict_hash is really about Ada names. From the inconsistency department, minimal symbol hashing doesn't go via dict_hash, so Ada's wild matching can't ever work with minimal symbols. This patch starts fixing this, by doing two things: #1 - adds a language vector method to let each language decide how to compute a symbol name hash. #2 - makes dictionaries know the language of the symbols they hold, and then use the dictionaries language to decide which hashing method to use. For now, this is just scaffolding, since all languages install the default method. The series will make C++ install its own hashing method later on, and will add per-language symbol name comparison routines too. This patch was originally based on a patch that Keith wrote for the libcc1/C++ WIP support. gdb/ChangeLog: 2017-11-08 Keith Seitz <keiths@redhat.com> Pedro Alves <palves@redhat.com> * ada-lang.c (ada_language_defn): Install default_search_name_hash. * buildsym.c (struct buildsym_compunit): <language>: New field.

2017-07-20Make language_def O(1)Pedro Alves1-10/+1
Profiling GDB with the rest of series applied, I saw calls to language_def showing up high in some runs. The problem is that language_def is O(N) currently, since walk the languages vector each time to find the matching language_defn. IMO, the add_language mechanism is pointless, because "enum language" implies the core of GDB needs to know about all languages anyway. So simply make the languages vector array be an array where each element's index is the corresponding enum language enumerator. Note that "local_language_defn" is gone along the way. It's just a copy of "auto", so the new code simply maps one to the other. One fewer place to update when we need to change the language vector... Also, a while ago the output of "set language" was made out of order as side effect of some other change. While I was at it, I made them sorted again. gdb/ChangeLog: 2017-07-20 Pedro Alves <palves@redhat.com> * ada-lang.c (ada_language_defn): Make extern.
