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. Also, while developing this errors in the implementation of the new printf formats showed up as regressions. gdb/ChangeLog 2019-10-01 Tom Tromey <tom@tromey.com> * p-lang.c (pascal_printstr): Use metadata style. * value.c (show_convenience): Use metadata style. * valprint.c (valprint_check_validity, val_print_optimized_out) (val_print_not_saved, val_print_unavailable) (val_print_invalid_address, generic_val_print, val_print) (value_check_printable, val_print_array_elements): Use metadata style. * ui-out.h (class ui_out) <field_fmt>: New overload. <do_field_fmt>: Add style parameter. * ui-out.c (ui_out::field_fmt): New overload. * typeprint.c (type_print_unknown_return_type) (val_print_not_allocated, val_print_not_associated): Use metadata style. * tui/tui-out.h (class tui_ui_out) <do_field_fmt>: Add style parameter. * tui/tui-out.c (tui_ui_out::do_field_fmt): Update. * tracepoint.c (tvariables_info_1): Use metadata style. * stack.c (print_frame_arg, print_frame_info, print_frame) (info_frame_command_core): Use metadata style. * skip.c (info_skip_command): Use metadata style. * rust-lang.c (rust_print_enum): Use metadata style. * python/py-prettyprint.c (print_stack_unless_memory_error): Use metadata style. * python/py-framefilter.c (py_print_single_arg): Use metadata style. * printcmd.c (do_one_display, print_variable_and_value): Use metadata style. * p-valprint.c (pascal_val_print) (pascal_object_print_value_fields): Use metadata style. * p-typeprint.c (pascal_type_print_base): Use metadata style. * mi/mi-out.h (class mi_ui_out) <do_field_fmt>: Add style parameter. * mi/mi-out.c (mi_ui_out::do_field_fmt): Update. * m2-valprint.c (m2_print_long_set): Use metadata style. * m2-typeprint.c (m2_print_type): Use metadata style. * infcmd.c (print_return_value_1): Use metadata style. * gnu-v3-abi.c (print_one_vtable): Use metadata style. * f-valprint.c (info_common_command_for_block): Use metadata style. * f-typeprint.c (f_type_print_base): Use metadata style. * expprint.c (print_subexp_standard): Use metadata style. * cp-valprint.c (cp_print_value_fields): Use metadata style. * cli/cli-style.h (class cli_style_option): Add constructor.

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.

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.
2018-06-18Remove 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.

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.

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.

2017-07-17Introduce class completion_tracker & rewrite completion<->readline interactionPedro Alves1-1/+1
This patch reworks the whole completion machinery, and prepares it for later enhancements. Adds a new "completion_tracker" class that is meant to hold everything about the state of the current completion operation. This class now has the responsibility of tracking the list of completion matches, and checking whether the max completions limit has been reached. You can look at this as this patch starting out by C++fying the existing "completion_tracker" in symtab.c (it's just an htab_t typedef currently), moving it to completer.h/c, and then making it a class/generalizing/enhancing it. Unlike with the current tracking, completion_tracker now checks whether the limit has been reached on each completion match list insertion. This both simplifies the max-completions handling code (maybe_add_completion_enum is gone, for example), and is a prerequisite for follow up patches. The current completion_tracker is only used for symbol completions, and the symbol code gets at the current instance via globals. This patch cleans that up by adding a completion_tracker reference to the signature of the completion functions, and passing the tracker around everywhere necessary. Then, the patch changes how the completion match list is handed over to readline. Currently, we're using the rl_completion_entry_function readline entry point, and the patch switches to rl_attempted_completion_function. A following patch will want to let GDB itself decide the common completion prefix between all matches (what readline calls the "lowest common denominator"), instead of having readline compute it, and that's not possible with the rl_completion_entry_function entry point. Also, rl_attempted_completion_function lets GDB hand over the match list to readline as an array in one go instead of passing down matches one by one, so from that angle it's a nicer entry point anyway. Lastly, the patch catches exceptions around the readline entry points, because we can't let C++ exceptions cross readline. We handle that in the readline input entry point, but the completion entry point isn't guarded, so GDB can abort if completion throws. E.g., in current master: (gdb) b -function "fun<tab> terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR' Aborted (core dumped) This patch fixes that. This will be exercised in the new tests added later on in the series. gdb/ChangeLog: 2017-07-17 Pedro Alves <palves@redhat.com> * ada-lang.c (symbol_completion_match): Adjust comments.

2017-05-19Use watchpoint's language when re-parsing expressionTom Tromey1-0/+2
PR rust/21484 notes that watch -location does not work with Rust: (gdb) watch -location a syntax error in expression, near `) 0x00007fffffffe0f4'. update_watchpoint tries to tell gdb that the new expression it creates has C syntax: /* The above expression is in C. */ b->language = language_c; However, update_watchpoint doesn't actually use this language when re-parsing the expression. Originally I was going to fix this by saving and restoring the language in update_watchpoint, but this regressed gdb.dlang/watch-loc.exp, because the constructed expression actually has D syntax (specifically the name is not parseable by C). Next I looked at directly constructing an expression, and not relying on the parser at all; but it seemed to me that upon a re-set, we'd want to reparse the type, and there is no existing API to do this correctly. So, in the end I made a hook to let each language choose what expression to use. I made all the languages other than Rust use the C expression, because that is the status quo ante. However, this is probably not truly correct. After this patch, at least, it is easy to correct by someone who knows the language(s) in question. Regtested by the buildbot.

2016-06-23Move logic out of symbol_find_demangled_nameTom Tromey1-0/+1
This patch moves most of the demangling logic out of symbol_find_demangled_name into the various language_defn objects. The simplest way to do this seemed to be to add a new method to language_defn. This is shame given the existing la_demangle, but given Ada's unusual needs, and the differing demangling options between languages, la_demangle didn't seem to fit. In order to make this work, I made enum language order-sensitive.

2016-04-22Centralize yacc interface names remapping (yyparse, yylex, yyerror, etc)Pedro Alves1-1/+1
This factors out all the yy-variables remapping to a single file, instead of each parser having to do the same, with different prefixes. With this, a parser just needs to define the prefix they want and include yy-remap.h, which does the dirty job. Note this renames the c_error, ada_error, etc. functions. Writing the remapping pattern as: #define yyerror GDB_YY_REMAP (error) instead of: #define yyerror GDB_YY_REMAP (yyerror) would have avoided the renaming. However, that would be problematic if we have a macro 'foo' in scope, when we write: #define yyfoo GDB_YY_REMAP (foo) as that would expand 'foo'. The c_yyerror etc. naming end ups indicating that this is a yacc related function more clearly, so feels like a good change, anyway. gdb/ChangeLog: 2016-04-22 Pedro Alves <palves@redhat.com> * ada-exp.y: Remove all yy symbol remappings.

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.

2014-12-12the "compile" commandTom Tromey1-0/+2
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.

2014-02-26use bound_minsym as result for lookup_minimal_symbol et alTom Tromey1-4/+4
This patch changes a few minimal symbol lookup functions to return a bound_minimal_symbol rather than a pointer to the minsym. This change helps prepare gdb for computing a minimal symbol's address at the point of use. Note that this changes even those functions that ostensibly search a single objfile. That was necessary because, in fact, those functions can search an objfile and its separate debug objfiles; and it is important for the caller to know in which objfile the minimal symbol was actually found. The bulk of this patch is mechanical. 2014-02-26 Tom Tromey <tromey@redhat.com> * ada-lang.c (ada_update_initial_language): Update.

2013-10-25New field la_varobj_ops in struct language_defnYao Qi1-0/+2
This is a follow-up series to move language stuff out of varobj.c. This patch adds a new field la_varobj_ops in struct language_defn so that each language has varobj-related options. Not every language supports varobj, and the operations are identical to operations of c languages. 'struct language_defn' is the ideal place to save all language-related operations. After this patch, some cleanups can be done in patch 2/2, which removes language-related stuff completely from varobj.c. Regression tested on x86_64-linux. gdb: 2013-10-25 Yao Qi <yao@codesourcery.com> * language.h (struct lang_varobj_ops): Declare.

2012-03-02language-specific read_var_value for Ada renamingsJoel Brobecker1-0/+1
The purpose of this patch is to better support renamings in the "info locals" command. Consider ... procedure Foo is GV : Integer renames Pck.Global_Variable; begin Increment (GV); -- STOP end Foo; ... Pck.Global_Variable is just an integer. After having stopped at the "STOP" line, "info locals" yields: (gdb) info locals gv = <error reading variable gv (Cannot access memory at address 0xffffffffffffffff)> In reality, two things are happening: (1) Variable "GV" does not exist, which is normal, since there is "GV" the renaming of another variable; (2) But to allow the user access to that renaming the same way the code has, the compiler produces an artificial variable whose name encodes the renaming: gv___XR_pck__global_variable___XE For practical reasons, the artificial variable itself is given irrelevant types and addresses. But the "info locals" command does not act as if it was a short-cut of "foreach VAR in locals, print VAR". Instead it gets the value of each VAR directly, which does not work in this case, since the variable is artificial and needs to be decoded first. This patch makes the "read_var_value" routine language-specific. The old implementation of "read_var_value" gets renamed to "default_read_var_value" and all languages now use it (unchanged behavior), except for Ada. In Ada, the new function ada_read_var_value checks if we have a renaming, and if so, evaluates its value, or else defers to default_read_var_value. gdb/ChangeLog: * language.h (struct language_defn): New "method" la_read_var_value. * findvar.c: #include "language.h".

2012-02-08Rename la_get_symbol_name_match_p into la_get_symbol_name_cmpJoel Brobecker1-1/+1
The la_get_symbol_name_match_p language hook was poorly named, as it suggested that the function should return nonzero if the names match, whereas it is the exact opposite.
