2022-07-28Rewrite registry.hTom Tromey1-13/+2
This rewrites registry.h, removing all the macros and replacing it with relatively ordinary template classes. The result is less code than the previous setup. It replaces large macros with a relatively straightforward C++ class, and now manages its own cleanup. The existing type-safe "key" class is replaced with the equivalent template class. This approach ended up requiring relatively few changes to the users of the registry code in gdb -- code using the key system just required a small change to the key's declaration. All existing users of the old C-like API are now converted to use the type-safe API. This mostly involved changing explicit deletion functions to be an operator() in a deleter class. The old "save/free" two-phase process is removed, and replaced with a single "free" phase. No existing code used both phases. The old "free" callbacks took a parameter for the enclosing container object. However, this wasn't truly needed and is removed here as well.
2022-06-12Remove addrmap wrapper functionsTom Tromey1-1/+1
This removes the various addrmap wrapper functions in favor of simple method calls on the objects themselves.
2022-06-02gdb: Do not add empty sections to the section mapIlya Leoshkevich1-1/+7
From: Ulrich Weigand <ulrich.weigand@de.ibm.com> build_objfile_section_table () creates four synthetic sections per objfile, which are collected by update_section_map () and passed to std::sort (). When there are a lot of objfiles, for example, when debugging JITs, the presence of these sections slows down the sorting significantly. The output of update_section_map () is used by find_pc_section (), which can never return any of these sections: their size is 0, so they cannot be accepted by bsearch_cmp (). Filter them (and all the other empty sections) out in insert_section_p (), which is used only by update_section_map ().
2022-05-31Use unique_ptr for objfilesTom Tromey1-3/+1
A while back, I changed objfiles to be held via a shared_ptr. The idea at the time was that this was a step toward writing to the index cache in the background, and this would let gdb keep a reference alive to do so. However, since then we've rewritten the DWARF reader, and the new index can do this without requiring a shared pointer -- in fact there are patches pending to implement this. This patch switches objfile management to unique_ptr, which makes more sense now. Regression tested on x86-64 Fedora 34.

2022-04-18gdbsupport: make gdb_abspath return an std::stringSimon Marchi1-2/+2
I'm trying to switch these functions to use std::string instead of char arrays, as much as possible. Some callers benefit from it (can avoid doing a copy of the result), while others suffer (have to make one more copy). Change-Id: Iced49b8ee2f189744c5072a3b217aab5af17a993

2022-04-07gdb: remove symtab::objfileSimon Marchi1-1/+1
Same idea as previous patch, but for symtab::objfile. I find it clearer without this wrapper, as it shows that the objfile is common to all symtabs of a given compunit. Otherwise, you could think that each symtab (of a given compunit) can have a specific objfile. Change-Id: Ifc0dbc7ec31a06eefa2787c921196949d5a6fcc6

2022-02-06gdb: move compunit_filetabs to compunit_symtab::filetabsSimon Marchi1-1/+1
Make compunit_filetabs, used to iterate a compunit_symtab's filetabs, a method of compunit_symtab. The name filetabs conflicts with the current name of the field. Rename the field to m_filetabs, since at this point nothing outside of compunit_symtab uses it, so we should treat it as private (even though it's not actually private). Rename the last_filetab field to m_last_filetab as well (it's only used on compunit_symtab::add_filetab). Adjust the COMPUNIT_FILETABS macro to keep its current behavior of returning the first filetab. Change-Id: I537b553a44451c52d24b18ee1bfa47e23747cfc3

2021-10-18CTF: incorrect underlying type setting for enumeration typesWeimin Pan1-0/+26
A bug was filed against the incorrect underlying type setting for an enumeration type, which was caused by a copy and paste error. This patch fixes the problem by setting it by calling objfile_int_type, which was originally dwarf2_per_objfile::int_type, with ctf_type_size bits. Also add error checking on ctf_func_type_info call.
2021-06-28gdb: convert obj_section macros to methodsSimon Marchi1-14/+13
Convert these three macros to methods of obj_section. The problem fixed by the following patch is caused by an out of bound access of the objfile::section_offsets vector. Since this is deep in macros, we don't get a clear backtrace and it's difficult to debug. Changing that to methods means we can step in them and break on them. Because their implementation requires knowing about struct objfile, move struct obj_section below struct objfile in objfiles.h. The obj_section_offset was used in one place as an lvalue to set offsets, in machoread.c. Replace that with a set_offset method. Add the objfile::section_offset and objfile::set_section_offset methods to improve encapsulation (reduce other objects poking into struct objfile's internals). gdb/ChangeLog: * objfiles.h (struct obj_section): Move down. <offset, set_offset, addr, endaddr>: New. (obj_section_offset, obj_section_addr, obj_section_endaddr), replace all users to use obj_section methods. (struct objfile) <section_offset, set_section_offset>: New.

2021-04-02gdb: remove objfile parameter from get_objfile_bfd_dataSimon Marchi1-6/+4
I noticed it was unused. I think that makes sense, as it shows that objfile_per_bfd_storage is not specific to one objfile (it can be shared by multiple objfiles that have the same bfd). There is one thing I wonder though, maybe I'm missing something. If the BFD doesn't require relocation, get_objfile_bfd_data stores the newly allocated object in objfiles_bfd_data, so we can assume that objfiles_bfd_data is the owner of the object. When the bfd's refcount drops to 0, the corresponding objfile_per_bfd_storage object in objfiles_bfd_data is deleted. But if the BFD requires relocation, get_objfile_bfd_data returns a newly allocated object that isn't kept anywhere else (and isn't shared). So the objfile becomes the owner of the objfile_per_bfd_storage object. In objfile::~objfile, we have this: if (obfd) gdb_bfd_unref (obfd); else delete per_bfd; I'm thinking that obfd could be non-nullptr, and it could require relocation. In that case, it would never be freed. Anyway, that's not really connected to this patch. gdb/ChangeLog: * objfiles.c (get_objfile_bfd_data): Remove objfile parameter, adjust callers. Change-Id: Ifa3158074ea6b42686780ba09d0c964b0cf14cf1
2021-04-02gdb: pass objfile_per_bfd_storage instead of objfile to partial_symtabSimon Marchi1-1/+1
Since partial_symtab is supposed to be objfile-independent (since series [1]), I think it would make sense for partial_symtab to not take an objfile as a parameter in its constructor. This patch replaces that parameter with an objfile_per_bfd_storage parameter. The objfile is used for two things: - to get the objfile_name, for debug messages. We can get that name from the bfd instead. - to intern the partial symtab filename. Even though it goes through an objfile method, the request is actually forwarded to the underlying objfile_per_bfd_storage. So we can ask the new objfile_per_bfd_storage instead. In order to get a reference to the BFD from the objfile_per_bfd_storage, the BFD is saved in the objfile_per_bfd_storage object.

2021-03-20Switch objfile to hold a list of psymbol readersTom Tromey1-2/+2
This changes objfile::qf to be a forward_list, and then updates all the uses to iterate over the list. Note that there is still only ever a single element in the list; this is handled by clearing the list whenever an object is added. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * dwarf2/read.c (dwarf2_build_psymtabs): Update. * symfile.c (syms_from_objfile_1, reread_symbols): Update. * symfile-debug.c (objfile::has_partial_symbols) (objfile::find_last_source_symtab) (objfile::forget_cached_source_info) (objfile::map_symtabs_matching_filename, objfile::lookup_symbol) (objfile::print_stats, objfile::dump) (objfile::expand_symtabs_for_function) (objfile::expand_all_symtabs) (objfile::expand_symtabs_with_fullname) (objfile::map_matching_symbols) (objfile::expand_symtabs_matching) (objfile::find_pc_sect_compunit_symtab) (objfile::map_symbol_filenames) (objfile::find_compunit_symtab_by_address) (objfile::lookup_global_symbol_language) (objfile::require_partial_symbols): Update. * psymtab.c (maintenance_print_psymbols) (maintenance_info_psymtabs, maintenance_check_psymtabs): Update. * objfiles.h (struct objfile) <qf>: Now a forward_list. * objfiles.c (objfile_relocate1): Update. * elfread.c (elf_symfile_read): Update.
2021-03-20Rearrange psymtab_storage constructionTom Tromey1-1/+0
This changes objfile so that it doesn't construct a psymtab_storage object until the psymtab functions are installed. It also applies a similar treatment to reread_symbols. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * symfile.c (syms_from_objfile_1): Call reset_psymtabs.

2021-03-20Move psymbol_map out of objfileTom Tromey1-3/+3
objfile::psymbol_map is used to implement a Rust feature. It is currently specific to partial symbols -- it isn't used by the DWARF indices. This patch moves it out of objfile and into psymbol_functions, adding a new method to quick_symbol_functions to handle the clearing case. This is needed because the map holds unrelocated addresses. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * quick-symbol.h (struct quick_symbol_functions) <relocated>: New method. * psymtab.h (struct psymbol_functions) <relocated>: New method. <fill_psymbol_map>: Declare method. <m_psymbol_map>: New member. * psymtab.c (psymbol_functions::fill_psymbol_map): Rename.

2021-03-20Introduce method wrappers for quick_symbol_functionsTom Tromey1-19/+0
This introduces wrappers for each function in quick_symbol_functions. The wrappers are methods on objfile, and are defined in symfile-debug.c, so that they can use the symfile_debug variable.

2021-02-10gdb: delete SYMBOL_SECTION and MSYMBOL_SECTION macrosAndrew Burgess1-2/+2
Delete two more symbol/section related macros. This time it's SYMBOL_SECTION and MSYMBOL_SECTION. As with general_symbol_info::m_name it is not currently possible to make general_symbol_info::m_section private as general_symbol_info must remain a POD type. But other than failing to make the new m_section private, this change does what you'd expect, adds a get and set member function and updates all users to use the new functions instead of the previous wrapper macros.

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-20/+20
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

2020-01-08Change section_offsets to a std::vectorTom Tromey1-41/+24
This changes section_offsets to be specialization of a std::vector and updates all the users. It also removes the ANOFFSET and SIZEOF_N_SECTION_OFFSETS macros. Most of this is just a generic sort of cleanup, that reduces the number of lines of code. However, a couple spots were doing weird things. objfile_relocate did: - std::vector<struct section_offsets> - new_debug_offsets (SIZEOF_N_SECTION_OFFSETS (debug_objfile->num_sections)); ... which seems to greatly over-estimate the number of elements needed. This appeared in set_objfile_default_section_offset: - std::vector<struct section_offsets> offsets (objf->num_sections, - { { offset } }); ... which makes sense due to type safety, but is also actively confusing given that section_offsets was previously also a kind of vector type.

The simplest way to do this was to introduce a new iterator that will return the underlying objfile, rather than a shared_ptr. (I also tried changing the rest of gdb to use shared_ptr, but this was quite large; and to using intrusive reference counting, but this also was tricky.) gdb/ChangeLog 2019-12-12 Tom Tromey <tom@tromey.com> * progspace.h (objfile_list): New typedef.

2019-12-12Move free_all_objfiles to program_spaceTom Tromey1-15/+0
This changes free_all_objfiles to be a method on program_space, in line with the other changes to treat program_space as a container for objfiles. gdb/ChangeLog 2019-12-12 Tom Tromey <tom@tromey.com> * symfile.c (symbol_file_clear): Update. * progspace.h (struct program_space) <free_all_objfiles>: Declare method. * progspace.c (program_space::free_all_objfiles): New method. * objfiles.h (free_all_objfiles): Don't declare. * objfiles.c (free_all_objfiles): Move to program_space.

2019-12-12Introduce program_space::remove_objfileTom Tromey1-28/+1
This introduces a new method, program_space::remove_objfile, and changes the objfile destructor not to unlink an objfile from the program space's list. This is cleaner because, like the previous patch, it treats the program space more like a container for objfiles. Also, this makes it possible to keep an objfile alive even though it has been unlinked from the program space's list, which is important for processing in a worker thread. gdb/ChangeLog 2019-12-12 Tom Tromey <tom@tromey.com> * progspace.h (struct program_space) <remove_objfile>: Declare. * progspace.c (program_space::remove_objfile): New method. * objfiles.c (unlink_objfile): Remove.

2019-12-12Introduce program_space::add_objfileTom Tromey1-45/+6
This introduces a new method, program_space::add_objfile, that adds an objfile to the program space's list of objfiles. It also changes the obfile's constructor so that linking an objfile into this list is not done here. The former is an improvement because it makes more sense to treat the program space as a container holding objfiles -- so manipulation of the list belongs there. The latter is not strictly needed, but seemed better both because it is removing a global side effect from a constructor, and for symmetry reasons, as a subsequent patch will remove unlinking from the destructor. gdb/ChangeLog 2019-12-12 Tom Tromey <tom@tromey.com> * progspace.h (struct program_space) <add_objfile>: Declare method. * progspace.c (program_space::add_objfile): New method. * objfiles.c (~objfile): Don't unlink objfile. (put_objfile_before): Remove. (add_separate_debug_objfile): Don't call put_objfile_before. (objfile::make): Call add_objfile. Set new_objfiles_available on the per-program-space data.

2019-12-12Make the objfile destructor privateTom Tromey1-3/+11
The idea behind this is that, in the long run, some code will need to be able to hold onto an objfile after it is unlinked from the program space. In particular, this is needed for some functionality to be moved to worker threads -- otherwise the objfile can be deleted while still in use. So, this makes ~objfile private, replacing it with an "unlink" method, making it more obvious which operation is intended at the calling points. gdb/ChangeLog 2019-12-12 Tom Tromey <tom@tromey.com> * symfile.c (syms_from_objfile_1): Use objfile_up. (syms_from_objfile_1, remove_symbol_file_command): Call unlink method. (reread_symbols): Use objfile_up. * solib.c (update_solib_list, reload_shared_libraries_1): Call unlink method. * objfiles.h (struct objfile) <~objfile>: Now private. <unlink>: New method. (struct objfile_deleter): New. (objfile_up): New typedef. * objfiles.c (objfile::unlink): New method. (free_objfile_separate_debug, free_all_objfiles) (objfile_purge_solibs): Use it. * jit.c (jit_unregister_code): Remove. (jit_inferior_exit_hook, jit_event_handler): Call unlink on objfile. * compile/compile-object-run.c (do_module_cleanup): Call unlink on objfile. * compile/compile-object-load.c (compile_object_load): Use objfile_up.

2019-10-21gdb: Ensure that !(a < a) is true in sort_cmp on obj_section objectsAndrew Burgess1-6/+10
After the switch to use std::sort, if GDB is compiled with the -D_GLIBCXX_DEBUG=1 flag then we see an error when using sort_cmp (in objfiles.c) to sort obj_section objects. The problem is that std::sort checks that the condition !(a < a) holds, and currently this is not true. GDB's sort_cmp is really designed to sort lists in which no obj_section repeats, however, there is some code in place to try and ensure we get a stable sort order if there is a bug in GDB, unfortunately this code fails the above check. By reordering some of the checks inside sort_cmp, it is pretty easy to ensure that the !(a < a) condition holds. I've not bothered to make this condition check optimal, like I said this code is only in place to ensure that we get stable results if GDB goes wrong, so I've made the smallest change needed to get the correct behaviour. After this commit I see no regressions when running GDB compiled with -D_GLIBCXX_DEBUG=1. gdb/ChangeLog: * objfiles.c (sort_cmp): Ensure that !(a < a) holds true.

2019-10-20Make unlink_objfile and put_objfile_before staticTom Tromey1-33/+22
I noticed an obsolete comment just before unlink_objfile, and then I noticed that both unlink_objfile and put_objfile_before could be static. This patch makes these changes, and also moves unlink_objfile earlier, so that a forward declaration is not needed. Tested by rebuilding. gdb/ChangeLog 2019-10-20 Tom Tromey <tom@tromey.com> * objfiles.h (unlink_objfile, put_objfile_before): Don't declare. * objfiles.c (unlink_objfile): Move earlier. Now static. Remove obsolete comment. (put_objfile_before): Now static. Change-Id: I1b5927a60fd1cc59bfc9c6761f61652a01ef13e0
