2021-11-10gdb: adjust x_file fields on COFF readersClément Chigot1-3/+3
Commit e86fc4a5bc37 ("PR 28447: implement multiple parameters for .file on XCOFF") changes the structure associated to the internal representation of files in COFF formats. However, gdb directory update has been forgotten, leading to compilation errors of this kind: CXX coffread.o /home/simark/src/binutils-gdb/gdb/coffread.c: In function 'const char* coff_getfilename(internal_auxent*)': /home/simark/src/binutils-gdb/gdb/coffread.c:1343:29: error: 'union internal_auxent::<unnamed struct>::<unnamed>' has no member named 'x_zeroes' 1343 | if (aux_entry->x_file.x_n.x_zeroes == 0) | ^~~~~~~~ Fix it by adjusting the COFF code in GDB.

2021-05-27gdb: fix some indentation issuesSimon Marchi1-12/+13
I wrote a small script to spot a pattern of indentation mistakes I saw happened in breakpoint.c. And while at it I ran it on all files and fixed what I found. No behavior changes intended, just indentation and addition / removal of curly braces. gdb/ChangeLog: * Fix some indentation mistakes throughout. gdbserver/ChangeLog: * Fix some indentation mistakes throughout.

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.

2021-03-20Allow multiple partial symbol readers per objfileTom Tromey1-1/+3
This patch finally changes gdb so that an objfile can have multiple sources of partial symbols (or mixed partial symbols and other kinds of indices). 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 Tromey1-14/+25
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 Tromey1-8/+14
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.

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.

2021-03-20Introduce dwarf2/public.hTom Tromey1-0/+1
This moves some more DWARF code out of symfile.h and into a new header, dwarf2/public.h. This header is intended to describe the public API of the DWARF reader. gdb/ChangeLog 2021-03-20 Tom Tromey <tom@tromey.com> * coffread.c: Include dwarf2/public.h. * dwarf2/frame.c: Include dwarf2/public.h. * dwarf2/index-write.h: Include dwarf2/public.h, not symfile.h. * dwarf2/public.h: New file. * dwarf2/read.c: Include dwarf2/public.h. * elfread.c: Include dwarf2/public.h. * machoread.c: Include dwarf2/public.h. * symfile.h (dwarf2_has_info, enum dw_index_kind) (dwarf2_initialize_objfile, dwarf2_build_psymtabs) (dwarf2_build_frame_info): Move to dwarf2/public.h. * xcoffread.c: Include dwarf2/public.h.
2021-03-06Create new file dwarf2/sect-names.hTom Tromey1-0/+1
This creates a new file, dwarf2/sect-names.h, and moves some DWARF-specific type definitions from symfile.h into it. gdb/ChangeLog 2021-03-06 Tom Tromey <tom@tromey.com> * xcoffread.c: Include sect-names.h. * symfile.h (struct dwarf2_section_names, struct dwarf2_debug_sections): Move to dwarf2/sect-names.h. * dwarf2/sect-names.h: New file, from symfile.h. * dwarf2/read.c: Include sect-names.h.
2021-02-10gdb: delete SYMBOL_SECTION and MSYMBOL_SECTION macrosAndrew Burgess1-4/+4
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. There should be no user visible change after this commit. gdb/ChangeLog: * coff-pe-read.c (add_pe_forwarded_sym): Make use of section_index and set_section_index member functions where appropriate. * coffread.c (coff_symtab_read): Likewise.

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-41/+41
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

2020-10-17Have partial symbol tables own psymbol vectorsTom Tromey1-54/+53
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.

2020-03-10gdb: Add support for tracking the DWARF line table is-stmt fieldAndrew Burgess1-0/+4
This commit brings support for the DWARF line table is_stmt field to GDB. The is_stmt field is used by the compiler when a single source line is split into multiple assembler instructions, especially if the assembler instructions are interleaved with instruction from other source lines. The compiler will set the is_stmt flag false from some instructions from the source lines, these instructions are not a good place to insert a breakpoint in order to stop at the source line. Instructions which are marked with the is_stmt flag true are a good place to insert a breakpoint for that source line. Currently GDB ignores all instructions for which is_stmt is false. This is fine in a lot of cases, however, there are some cases where this means the debug experience is not as good as it could be. Consider stopping at a random instruction, currently this instruction will be attributed to the last line table entry before this point for which is_stmt was true - as these are the only line table entries that GDB tracks. This can easily be incorrect in code with even a low level of optimisation. With is_stmt tracking in place, when stopping at a random instruction we now attribute the instruction back to the real source line, even when is_stmt is false for that instruction in the line table. When inserting breakpoints we still select line table entries for which is_stmt is true, so the breakpoint placing behaviour should not change. When stepping though code (at the line level, not the instruction level) we will still stop at instruction where is_stmt is true, I think this is more likely to be the desired behaviour. Instruction stepping is, of course, unchanged, stepping one instruction at a time, but we should now report more accurate line table information with each instruction step. The original motivation for this work was a patch posted by Bernd here: https://sourceware.org/ml/gdb-patches/2019-11/msg00792.html As part of that thread it was suggested that many issues would be resolved if GDB supported line table views, this isn't something I've attempted in this patch, though reading the spec, it seems like this would be a useful feature to support in GDB in the future. The spec is here: http://dwarfstd.org/ShowIssue.php?issue=170427.1 And Bernd gives a brief description of the benefits here: https://sourceware.org/ml/gdb-patches/2020-01/msg00147.html With that all said, I think that there is benefit to having proper is_stmt support regardless of whether we have views support, so I think we should consider getting this in first, and then building view support on top of this. The gdb.cp/step-and-next-inline.exp test is based off a test proposed by Bernd Edlinger in this message: https://sourceware.org/ml/gdb-patches/2019-12/msg00842.html gdb/ChangeLog: * buildsym-legacy.c (record_line): Pass extra parameter to record_line. * buildsym.c (buildsym_compunit::record_line): Take an extra parameter, reduce duplication in the line table, and record the is_stmt flag in the line table. * buildsym.h (buildsym_compunit::record_line): Add extra parameter. * disasm.c (do_mixed_source_and_assembly_deprecated): Ignore non-statement lines. * dwarf2/read.c (dwarf_record_line_1): Add extra parameter, pass this to the symtab builder.

2020-01-26Introduce partial_symtab::expand_psymtab methodTom Tromey1-4/+5
The symbol readers generally used two functions to expand a partial symtab: an outer function (now the "read_symtab" method), and an inner function, typically named something like "psymtab_to_symtab". This patch changes this second step to be a method on partial_symtab, and updates all the callers. For legacy_psymtab, a new function pointer member is introduced. This patch enables a subsequent cleanup. gdb/ChangeLog 2020-01-26 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_psymtab_to_symtab_1): Change argument order. Call expand_psymtab.

2020-01-26Consolidate psymtab "Reading" messagesTom Tromey1-19/+1
Each symbol reader implemented its own "Reading..." messages, and most of them double-checked that a previously-expanded psymtab could not be re-read. This patch consolidates the message-printing, and changes these checks into asserts. gdb/ChangeLog 2020-01-26 Tom Tromey <tom@tromey.com> * xcoffread.c (xcoff_read_symtab): Remove prints.

2020-01-26Introduce partial_symtab::read_symtab methodTom Tromey1-21/+22
This introduces a new partial_symtab::read_symtab method, and updates the symbol readers to subclass partial_symtab and implement this method. The old read_symtab and read_symtab_private members are removed. In practice, only DWARF and CTF are truly updated to take advantage of the new setup. The other symbol readers are less actively maintained, and so this patch also introduces a "legacy_psymtab", which essentially works the same way as the old partial_symtab. (Note that, without more knowledge of the interaction between these symbol readers, fixing this to remove the new (small) overhead is not trivial, because these readers copy the read_symtab pointer between partial symtabs.) gdb/ChangeLog 2020-01-26 Tom Tromey <tom@tromey.com> * xcoffread.c (this_symtab_psymtab, read_xcoff_symtab) (xcoff_psymtab_to_symtab_1, xcoff_read_symtab) (xcoff_start_psymtab, xcoff_end_psymtab, scan_xcoff_symtab): Use legacy_symtab. * stabsread.h (dbx_end_psymtab): Use legacy_symtab. * psymtab.c (psymtab_to_symtab): Call method.

2020-01-26Turn start_psymtab_common into a constructorTom Tromey1-5/+2

This is the next step in getting the symbol readers to allocate psymtabs themselves: change allocate_psymtab to be an ordinary constructor, and then use "new" at the previous call sites.

2020-01-13Dwarf 5: Handle debug_str_offsets and indexed attributes that have base offsets.Ali Tamur1-0/+1
* Process debug_str_offsets section. Handle DW_AT_str_offsets_base attribute and keep the value in dwarf2_cu. * Make addr_base field in dwarf2_cu optional to disambiguate 0 value (absent or present and 0). * During parsing, there is no guarantee that DW_AT_str_offsets_base and DW_AT_rnglists_base fields will be processed before the attributes that need those values for correct computation. So make two passes, on the first one mark the attributes that depend on *_base attributes and process only the others. On the second pass, only process the attributes that are marked on the first pass. * For string attributes, differentiate between addresses that directly point to a string and those that point to an offset in debug_str_offsets section. * There are now two attributes, DW_AT_addr_base and DW_AT_GNU_addr_base to read address offset base. Likewise, there are two attributes, DW_AT_rnglists_base and DW_AT_GNU_ranges_base to read ranges base. Since there is no guarantee which ones the compiler will generate, create helper functions to handle all cases. Tested with CC=/usr/bin/gcc (version 8.3.0) against master branch (also with -gsplit-dwarf and -gdwarf-4 flags) and there was no increase in the set of tests that fails. (gdb still cannot debug a 'hello world' program with DWARF 5, so for the time being, this is all we care about). This is part of an effort to support DWARF-5 in gdb.
2020-01-13gdb: add back declarations for _initialize functionsSimon Marchi1-1/+2
I'd like to enable the -Wmissing-declarations warning. However, it warns for every _initialize function, for example: CXX dcache.o /home/smarchi/src/binutils-gdb/gdb/dcache.c: In function ‘void _initialize_dcache()’: /home/smarchi/src/binutils-gdb/gdb/dcache.c:688:1: error: no previous declaration for ‘void _initialize_dcache()’ [-Werror=missing-declarations] _initialize_dcache (void) ^~~~~~~~~~~~~~~~~~ The only practical way forward I found is to add back the declarations, which were removed by this commit: commit 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9 Author: John Baldwin <jhb@FreeBSD.org> Date: Sat Sep 9 11:02:37 2017 -0700 Remove unnecessary function prototypes. I don't think it's a big problem to have the declarations for these functions, but if anybody has a better solution for this, I'll be happy to use it. gdb/ChangeLog: * aarch64-fbsd-nat.c

2020-01-08Change section_offsets to a std::vectorTom Tromey1-15/+9
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.

2019-10-29Change some arguments to gdb::string_view instead of name+lenChristian Biesinger1-17/+25
Just some code cleanup. This change has a few benefits: - Shorter argument list in the functions - If the caller needs to calculate the string, they no longer need to explicitly call strlen - It is easy to pass std::string to this (done in one place currently) This also updates a couple of places that were passing 0/1 to a bool parameter. gdb/ChangeLog: 2019-10-29 Christian Biesinger <cbiesinger@google.com> * coffread.c (record_minimal_symbol): Update.

2019-10-02Change SYMBOL_VALUE_ADDRESS to be an rvalueTom Tromey1-2/+4
This changes SYMBOL_VALUE_ADDRESS to be an rvalue. The symbol readers generally assign using this, so this also introduces SET_SYMBOL_VALUE_ADDRESS and updates the readers. Making this change is useful in a subsequent patch, which redefined SYMBOL_VALUE_ADDRESS. gdb/ChangeLog 2019-10-02 Tom Tromey <tromey@adacore.com> * coffread.c (process_coff_symbol): Update. * dwarf2read.c (var_decode_location, new_symbol): Update. * mdebugread.c (parse_symbol): Update. * objfiles.c (relocate_one_symbol): Update. * stabsread.c (define_symbol, fix_common_block) (scan_file_globals): Update. * symtab.h (SYMBOL_VALUE_ADDRESS): Expand to an rvalue.

2019-09-19bfd_section_* macrosAlan Modra1-7/+6
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.
