2024-04-23gdb: move a bunch of quit-related things to event-top.{c,h}Simon Marchi1-0/+1
Move some declarations related to the "quit" machinery from defs.h to event-top.h. Most of the definitions associated to these declarations are in event-top.c. The exceptions are `quit()` and `maybe_quit()`, that are defined in utils.c. For consistency, move these two definitions to event-top.c. Include "event-top.h" in many files that use these things.

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.

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.

2023-11-21gdb: Use std::string_view instead of gdb::string_viewLancelot Six1-9/+9
Given that GDB now requires a C++17, replace all uses of gdb::string_view with std::string_view. This change has mostly been done automatically: - gdb::string_view -> std::string_view - #include "gdbsupport/gdb_string_view.h" -> #include <string_view> One things which got brought up during review is that gdb::stging_view does support being built from "nullptr" while std::sting_view does not. Two places are manually adjusted to account for this difference: gdb/tui/tui-io.c:tui_getc_1 and gdbsupport/format.h:format_piece::format_piece. The above automatic change transformed "gdb::to_string (const gdb::string_view &)" into "gdb::to_string (const std::string_view &)". The various direct users of this function are now explicitly including "gdbsupport/gdb_string_view.h". A later patch will remove the users of gdb::to_string. The implementation and tests of gdb::string_view are unchanged, they will be removed in a following patch.

2023-08-23gdb: fix up a few places where a char was treated as a boolAndrew Burgess1-2/+2
Spotted a few places where a char is being treated as a bool. The GDB style is to use explicit comparisons, so fix things up. There should be no user visible changes after this commit.
2023-08-23gdb: bfd_get_symbol_leading_char vs. ""Alan Modra1-3/+5
Some places matching the first char of a string against bfd_get_symbol_leading_char, which may be zero, didn't check for "". This could lead to accesses past the end of the string and potential buffer overruns. Fix that, and also get rid of a stupid optimisation in dbxread when looking for "__DYNAMIC" that also might access past the end of a string.
2023-08-18Merge psympriv.h into psymtab.hTom Tromey1-1/+1

2023-08-11gdb: warn unused result for bfd IO functionsAlan Modra1-3/+4
This fixes the compilation warnings introduced by my bfdio.c patch. The removed bfd_seeks in coff_symfile_read date back to 1994, commit 7f4c859520, prior to which the file used stdio rather than bfd to read symbols. Since it now uses bfd to read the file there should be no need to synchronise to bfd's idea of the file position. I also fixed a potential uninitialised memory access.

2023-03-17Fix line table regressionTom Tromey1-9/+12
Simon pointed out a line table regression, and after a couple of false starts, I was able to reproduce it by hand using his instructions. The bug is that most of the code in do_mixed_source_and_assembly uses unrelocated addresses, but one spot does: pc = low; ... after the text offset has been removed. This patch fixes the problem by introducing a new type to represent unrelocated addresses in the line table. This prevents this sort of bug to some degree (it's still possible to manipulate a CORE_ADDR in a bad way, this is unavoidable). However, this did let the compiler flag a few spots in that function, and now it's not possible to compare an unrelocated address from a line table with an ordinary CORE_ADDR. Regression tested on x86-64 Fedora 36, though note this setup never reproduced the bug in the first place. I also tested it by hand on the disasm-optim test program.
2023-03-11Change linetables to be objfile-independentTom Tromey1-3/+6
This changes linetables to not add the text offset to the addresses they contain. I did this in a few steps, necessarily combined together in one patch: I renamed the 'pc' member to 'm_pc', added the appropriate accessors, and then recompiled. Then I fixed all the errors. Where possible I generally chose to use the raw_pc accessor, as it is less expensive. Note that this patch discounts the possibility that the text section offset might cause wraparound in the addresses in the line table. However, this was already discounted -- in particular, objfile_relocate1 did not re-sort the table in this scenario. (There was a bug open about this, but as far as I can tell this has never happened, it's not even clear what inspired that bug.) Approved-By: Simon Marchi <simon.marchi@efficios.com>

2023-02-08Set section indices when symbols are madeTom Tromey1-1/+20
Most places in gdb that create a new symbol will apply a section offset to the address. It seems to me that the choice of offset here is also an implicit choice of the section. This is particularly true if you examine fixup_section, which notes that it must be called before such offsets are applied -- meaning that if any such call has an effect, it's purely by accident. This patch cleans up this area by tracking the section index and applying it to a symbol when the address is set. This is done for nearly every case -- the remaining cases will be handled in later patches.

2022-12-01Add name canonicalization for CTom Tromey1-0/+13
PR symtab/29105 shows a number of situations where symbol lookup can result in the expansion of too many CUs. What happens is that lookup_signed_typename will try to look up a type like "signed int". In cooked_index_functions::expand_symtabs_matching, when looping over languages, the C++ case will canonicalize this type name to be "int" instead. Then this method will proceed to expand every CU that has an entry for "int" -- i.e., nearly all of them. A crucial component of this is that the caller, objfile::lookup_symbol, does not do this canonicalization, so when it tries to find the symbol for "signed int", it fails -- causing the loop to continue. This patch fixes the problem by introducing name canonicalization for C. The idea here is that, by making C and C++ agree on the canonical name when a symbol name can have multiple spellings, we avoid the bad behavior in objfile::lookup_symbol (and any other such code -- I don't know if there is any). Unlike C++, C only has a few situations where canonicalization is needed. And, in particular, due to the lack of overloading (thus avoiding any issues in linespec) and due to the way c-exp.y works, I think that no canonicalization is needed during symbol lookup -- only during symtab construction. This explains why lookup_name_info is not touched. The stabs reader is modified on a "best effort" basis. The DWARF reader needed one small tweak in dwarf2_name to avoid a regression in dw2-unusual-field-names.exp. I think this is adequately explained by the comment, but basically this is a scenario that should not occur in real code, only the gdb test suite. lookup_signed_typename is simplified. It used to search for two different type names, but now gdb can search just for the canonical form. gdb.dwarf2/enum-type.exp needed a small tweak, because the canonicalizer turns "unsigned integer" into "unsigned int integer". It seems better here to use the correct C type name.

2022-10-19internal_error: remove need to pass __FILE__/__LINE__Pedro Alves1-2/+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.

2022-08-03Use gdb_bfd_ref_ptr in objfileTom Tromey1-11/+11
This changes struct objfile to use a gdb_bfd_ref_ptr. In addition to removing some manual memory management, this fixes a use-after-free that was introduced by the registry rewrite series. The issue there was that, in some cases, registry shutdown could refer to memory that had already been freed. This help fix the bug by delaying the destruction of the BFD reference (and thus the per-bfd object) until after the registry has been shut down.
2022-07-28Rewrite registry.hTom Tromey1-1/+1
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.

2022-02-21gdb: avoid nullptr access in dbxread.c from read_dbx_symtabAndrew Burgess1-49/+88
This fixes a GDB crash reported in bug pr/28900, related to reading in some stabs debug information. In this commit my goal is to stop GDB crashing. I am not trying to ensure that GDB makes the best possible use of the available stabs debug information. At this point I consider stabs a legacy debug format, with only limited support in GDB. So, the problem appears to be that, when reading in the stabs data, we need to find a N_SO entry, this is the entry that defines the start of a compilation unit (or at least the location of a corresponding source file). It is while handling an N_SO that GDB creates a psymtab to hold the incoming debug information (symbols, etc). The problem we hit in the bug is that we encounter some symbol information (an N_PC entry) outside of an N_SO entry - that is we find some symbol information that is not associated with any source file. We already have some protection for this case, look (in read_dbx_symtab) at the handling of N_PC entries of type 'F' and 'f', if we have no psymtab (the pst variable is nullptr) then we issue a complaint. However, for whatever reason, in both 'f' and 'F' handling, there is one place where we assume that the pst variable (the psymtab) is not nullptr. This is a mistake. In this commit, I guard these two locations (in 'f' and 'F' handling) so we no longer assume pst is not nullptr. While I was at it, I audited all the other uses of pst in read_dbx_symtab, and in every potentially dangerous case I added a nullptr check, and issue a suitable complaint if pst is found to be nullptr. It might well be true that we could/should do something smarter if we see a debug symbol outside of an N_SO entry, and if anyone wanted to do that work, they're welcome too. But this commit is just about preventing the nullptr access, and the subsequent GDB crash. I don't have any tests for this change, I have no idea how to generate weird stabs data for testing. The original binary from the bug report now loads just fine without GDB crashing. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=28900

2021-04-02gdb: pass objfile_per_bfd_storage instead of objfile to partial_symtabSimon Marchi1-2/+2
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.

This is done by having each symbol reader create its own psymbol_functions object and add it to the 'qf' list in the objfile. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_initial_scan): Create partial symtabs. * symfile.c (syms_from_objfile_1, reread_symbols): Update. * psymtab.h (make_psymbol_functions): Don't declare. * psymtab.c (make_psymbol_functions): Remove.

2021-03-20Add partial_symtabs parameter to psymtab construction functionsTom Tromey1-16/+26
This adds a partial_symtabs parameter to the psymtab constructors and to add_psymbol. This helps with the overall project of removing the partial symtabs from the objfile. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_start_psymtab): Add partial_symtabs parameter.

2021-03-20Remove sym_fns::sym_read_psymbolsTom Tromey1-1/+0
Partial symbols are read via the sym_fns::sym_read_psymbols function pointer. In order to separate the partial symbols from the objfile, this must instead be done via a virtual method on quick_symbol_functions. This patch implements this change. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_sym_fns): Update. * symfile.h (struct sym_fns) <sym_read_psymbols>: Remove. * symfile-debug.c (objfile::has_partial_symbols): Use can_lazily_read_symbols.

2021-03-20Change how some psymbol readers access the psymtab storageTom Tromey1-12/+20
Currently, all psymbol readers access the psymtab storage via the objfile. This is done directly at any spot requiring the storage. In order to move psymbols out of the objfile, the psymtab_storage must be passed in explicitly. This patch consolidates the access of the storage in a single place in these readers, updating various functions to pass the storage object around. "Hidden" uses, like "objfile->psymtabs ()", are also updated. The DWARF reader is not yet touched. That requires more complicated changes. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_end_psymtab): Add partial_symtabs parameter. (xcoff_end_psymtab): Update. (scan_xcoff_symtab): Add partial_symtabs parameter. (xcoff_initial_scan): Update. * stabsread.h (dbx_end_psymtab): Add partial_symtabs parameter. * mdebugread.c (mdebug_build_psymtabs): Update.

(dbx_end_psymtab): Add partial_symtabs parameter.
2021-03-20Move sym_fns::qf to objfileTom Tromey1-1/+0
Currently the "partial" symbol reader is attached to the objfile's symbol functions. However, in order to allow multiple separate partial symbol readers, this association must be changed. This patch moves the "qf" member out of sym_fns as a step toward that goal. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * psymtab.c (require_partial_symbols): Check that 'sf' is not null. * xcoffread.c (xcoff_sym_fns): Update. * symfile.h (struct sym_fns) <qf>: Remove. * 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, debug_sym_fns) (install_symfile_debug_logging): Update. * objfiles.h (struct objfile) <qf>: New member. * mipsread.c (ecoff_sym_fns): Update. * machoread.c (macho_sym_fns): Update. * elfread.c (elf_sym_fns_gdb_index, elf_sym_fns_debug_names): Don't declare.

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-72/+72
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

2020-11-01Remove init_psymbol_listTom Tromey1-3/+0
init_psymbol_list is now empty, and so this removes it. gdb/ChangeLog 2020-11-01 Tom Tromey <tom@tromey.com> * dbxread.c (dbx_symfile_read): Update. * dwarf2/read.c (dwarf2_build_psymtabs): Update. * xcoffread.c (xcoff_initial_scan): Update. * psympriv.h (init_psymbol_list): Don't declare. * psymtab.c (init_psymbol_list): Remove.
2020-10-17Have partial symbol tables own psymbol vectorsTom Tromey1-42/+41
Currently pointers to all partial symbols are stored in two vectors; and then indices into these vectors are stored in each partial_symtab. This patch changes this so that each partial symtab instead has vectors of symbols. add_psymbol_to_list can now be changed into a method on partial_symtab as well. My main motivation for doing this is that I am looking into calling sort_pst_symbols in the background. However, I haven't actually implemented this yet. (Also this may make it more feasible to also sort the static psymbols, though I haven't tried that either.) Also, though, this lets us remove the "current_global_psymbols" vector, because now the callers can simply refer directly to the psymtab that they are modifying (formerly this was implicit). The main drawback of this patch is that it increases the size of partial symtab. gdb/ChangeLog 2020-10-17 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_end_psymtab): Use partial_symtab::empty.
