bfd_section_* macros
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. (bfd_section_name, bfd_section_size, bfd_section_vma), (bfd_section_lma, bfd_section_alignment): Lose bfd parameter. (bfd_section_flags, bfd_section_userdata): New.

Don't include gdbarch.h from defs.h
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. The buildbot caught a few problems along these lines. gdb/ChangeLog 2019-07-10 Tom Tromey <tom@tromey.com> * defs.h: Don't include gdbarch.h. * aarch64-ravenscar-thread.c, aarch64-tdep.c, alpha-bsd-tdep.h, alpha-linux-tdep.c, alpha-mdebug-tdep.c, arch-utils.h, arm-tdep.h, ax-general.c, btrace.c, buildsym-legacy.c, buildsym.h, c-lang.c, cli/cli-decode.h, cli/cli-dump.c, cli/cli-script.h, cli/cli-style.h, coff-pe-read.h, compile/compile-c-support.c, compile/compile-cplus.h, compile/compile-loc2c.c, corefile.c, cp-valprint.c, cris-linux-tdep.c, ctf.c, d-lang.c, d-namespace.c, dcache.c, dicos-tdep.c, dictionary.c, disasm-selftests.c, dummy-frame.c, dummy-frame.h, dwarf2-frame-tailcall.c, dwarf2expr.c, expression.h, f-lang.c, frame-base.c, frame-unwind.c, frv-linux-tdep.c, gdbarch-selftests.c, gdbtypes.h, go-lang.c, hppa-nbsd-tdep.c, hppa-obsd-tdep.c, i386-dicos-tdep.c, i386-tdep.h, ia64-vms-tdep.c, interps.h, language.c, linux-record.c, location.h, m2-lang.c, m32r-linux-tdep.c, mem-break.c, memattr.c, mn10300-linux-tdep.c, nios2-linux-tdep.c, objfiles.h, opencl-lang.c, or1k-linux-tdep.c, p-lang.c, parser-defs.h, ppc-tdep.h, probe.h, python/py-record-btrace.c, record-btrace.c, record.h, regcache-dump.c, regcache.h, riscv-fbsd-tdep.c, riscv-linux-tdep.c, rust-exp.y, sh-linux-tdep.c, sh-nbsd-tdep.c, source-cache.c, sparc-nbsd-tdep.c, sparc-obsd-tdep.c, sparc-ravenscar-thread.c, sparc64-fbsd-tdep.c, std-regs.c, target-descriptions.h, target-float.c, tic6x-linux-tdep.c, tilegx-linux-tdep.c, top.c, tracefile.c, trad-frame.c, type-stack.h, ui-style.c, utils.c, utils.h, valarith.c, valprint.c, varobj.c, x86-tdep.c, xml-support.h, xtensa-linux-tdep.c, cli/cli-cmds.h: Update. * s390-linux-nat.c, procfs.c, inf-ptrace.c: Likewise. |

Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

Allocate minimal symbols with malloc
Currently, minimal symbols are allocated on the per-BFD obstack. However, it is also possible for multiple symbol readers to create minimal symbols for a given objfile. In this case, the minimal symbols will be reallocated on the obstack, leading to some waste of storage. This is a memory leak, but I think it won't be caught by tools like valgrind, because valgrind doesn't know about obstacks. This patch fixes the problem by using malloc to allocate the storage for minimal symbols. gdb/ChangeLog 2019-03-15 Tom Tromey <tom@tromey.com> * objfiles.h (struct objfile_per_bfd_storage) <msymbols>: Now a unique_xmalloc_ptr.

Simplify per-BFD storage management
There's no reason that the objfile_per_bfd_storage must be allocated via bfd_alloc.

Move psymtabs to their own obstack
Previously, the psymtab obstack was just a pointer to the objfile obstack. This patch changes psymtabs to use their own obstack, instead. A gdb::optional is used to avoid unnecessary allocation when the obstack is not needed. After this patch, the psymtab code lifetime model is that, in the core psymtab code, objects allocated on the psymtab obstack may point to other such objects, or to objects on the per-BFD obstack -- but never to the objfile obstack. Note however that this invariant is only obeyed the core psymtab code, and even there not quite fully: there is still a link from the psymtab to the full symtab. Symbol readers are free to work however they like; and in particular, even after this patch, in practice all symbol readers violate this invariant via the read_symtab_private field. gdb/ChangeLog 2019-01-10 Tom Tromey <tom@tromey.com> * objfiles.h (objfile::reset_psymtabs): Update. * objfiles.c (objfile::objfile): Update. * psymtab.h (psymtab_storage::obstack): Update.

Introduce class psymtab_storage
This introduces a new psymtab_storage class, which holds all psymbol-related objects that are independent of the objfile. (This latter contraint explains why psymbol_map was not moved; though this could still be done with some work.) This patch does not yet change where psymtab allocation is done -- that comes later. This just wraps everything in a single object to make further transformations simpler. Note that a shared_ptr is used to link from the objfile to the psymtab_storage object. The end goal here is to allow a given symbol reader to simply attach to the psymtab_storage object to the BFD, then reuse it in later invocations; shared_ptr makes this simple to reason about. gdb/ChangeLog 2019-01-10 Tom Tromey <tom@tromey.com> * symmisc.c (print_symbol_bcache_statistics): Update.

Update copyright year range in all GDB files.
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. |

Handle dereferencing Rust trait objects
In Rust, virtual tables work a bit differently than they do in C++. In C++, as you know, they are connected to a particular class hierarchy. Rust, instead, can generate a virtual table for potentially any type -- in fact, one such virtual table for each trait (a trait is similar to an abstract class or to a Java interface) that a type implements. Objects that are referenced via a trait can't currently be inspected by gdb. This patch implements the Rust equivalent of "set print object". gdb relies heavily on the C++ ABI to decode virtual tables; primarily to make "set print object" work; but also "info vtbl". However, Rust does not currently have a specified ABI, so this approach seems unwise to emulate. Instead, I've changed the Rust compiler to emit some DWARF that describes trait objects (previously their internal structure was opaque), vtables (currently just a size -- but I hope to expand this in the future), and the concrete type for which a vtable was emitted. The concrete type is expressed as a DW_AT_containing_type on the vtable's type. This is a small extension to DWARF. This patch adds a new entry to quick_symbol_functions to return the symtab that holds a data address. Previously there was no way in gdb to look up a full (only minimal) non-text symbol by address. The psymbol implementation of this method works by lazily filling in a map that is added to the objfile. This avoids slowing down psymbol reading for a feature that is likely to not be used too frequently. I did not update .gdb_index. My thinking here is that the DWARF 5 indices will obsolete .gdb_index soon-ish, meaning that adding a new feature to them is probably wasted work. If necessary I can update the DWARF 5 index code when it lands in gdb.

Introduce lookup_name_info and generalize Ada's FULL/WILD name matching
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 ..

Change objfile to use new/delete
This changes objfiles to use new and delete rather than xmalloc and free. Simon noticed that it uses a non-POD and so shouldn't be allocated with XCNEW; and I wanted to be able to use another non-POD as a member; this patch is the result. Regression tested by the buildbot. 2017-10-13 Tom Tromey <tom@tromey.com> * compile/compile-object-run.c (do_module_cleanup): Use delete. * solib.c (update_solib_list, reload_shared_libraries_1): Use delete. * symfile.c (symbol_file_add_with_addrs): Use new. (symbol_file_add_separate): Update comment. (syms_from_objfile_1, remove_symbol_file_command): Use delete. * jit.c (jit_object_close_impl): Use new. (jit_unregister_code): Use delete. * objfiles.c (objfile::objfile): Rename from allocate_objfile. (~objfile): Rename from free_objfile. (free_objfile_separate_debug, do_free_objfile_cleanup) (free_all_objfiles, objfile_purge_solibs): Use delete. * objfiles.h (struct objfile): Add constructor and destructor. Use DISABLE_COPY_AND_ASSIGN. Add initializers to data members. (allocate_objfile, free_objfile): Don't declare. (struct objstats): Add initializers. |

objfile_per_bfd_storage non-POD
A following patch will want to add a std::vector to objfile_per_bfd_storage. That makes it non-trivially constructible/destructible. Since objfile_per_bfd_storage objects are allocated on an obstack, we need to call their ctors/dtors manually. This is what this patch does. And then since we can now rely on ctors/dtors being run, make objfile_per_bfd_storage::storage_obstack be an auto_obstack. gdb/ChangeLog: 2017-06-27 Pedro Alves <palves@redhat.com> * objfiles.c (get_objfile_bfd_data): Call bfd_alloc instead of bfd_zalloc. Call objfile_per_bfd_storage's ctor. (free_objfile_per_bfd_storage): Call objfile_per_bfd_storage's dtor. * objfiles.h (objfile_per_bfd_storage): Add ctor. Make 'storage_obstack' field an auto_obstack. In-class initialize all non-bitfield fields. Make minsyms_read bool. * symfile.c (read_symbols): Adjust. |

Make symfile_add_flags and objfile->flags strongly typed
This makes these flag types be "enum flag" types. The benefit is
making use of C++'s stronger typing -- mixing the flags types by
mistake errors at compile time.
This caught one old bug in symbol_file_add_main_1 already, fixed by
this patch as well:
@@ -1318,7 +1326,7 @@ symbol_file_add_main_1 (const char *args, int from_tty, int flags)
what is frameless. */
reinit_frame_cache ();
- if ((flags & SYMFILE_NO_READ) == 0)
+ if ((add_flags & SYMFILE_NO_READ) == 0)
set_initial_language ();
}
Above, "flags" are objfile flags, not symfile_add_flags. So that was
actually checking for "flag & OBJF_PSYMTABS_READ", which has the same
value as SYMFILE_NO_READ...
I moved the flags definitions to separate files to break circular
dependencies.
Built with --enable-targets=all and tested on x86-64 Fedora 23.

Remove some unnecessary code
This patch removes some unnecessary code. In particular, terminate_minimal_symbol_table is declared in minsyms.h, so it doesn't need to be declared in objfiles.h as well. And, restore_ui_out_closure was rendered unnecessary by an earlier patch, so the structure definition can be removed now. I'm checking this in as obvious. Tested by rebuilding on x86-64 Fedora 24 with --enable-targets=all; which would notice any missing includes of minsyms.h. 2016-09-23 Tom Tromey <tom@tromey.com> * utils.c (struct restore_ui_out_closure): Remove. * objfiles.h (terminate_minimal_symbol_table): Don't declare. |

DWARF: handle non-local references in nested functions
GDB's current behavior when dealing with non-local references in the
context of nested fuctions is approximative:
- code using valops.c:value_of_variable read the first available stack
frame that holds the corresponding variable (whereas there can be
multiple candidates for this);
- code directly relying on read_var_value will instead read non-local
variables in frames where they are not even defined.
This change adds the necessary context to symbol reads (to get the block
they belong to) and to blocks (the static link property, if any) so that
GDB can make the proper decisions when dealing with non-local varibale
references.
gdb/ChangeLog:
* ada-lang.c (ada_read_var_value): Add a var_block argument
and pass it to default_read_var_value.
* block.c (block_static_link): New accessor.
* block.h (block_static_link): Declare it.
* buildsym.c (finish_block_internal): Add a static_link
argument. If there is a static link, associate it to the new
block.
(finish_block): Add a static link argument and pass it to
finish_block_internal.
(end_symtab_get_static_block): Update calls to finish_block and
to finish_block_internal.
(end_symtab_with_blockvector): Update call to
finish_block_internal.
* buildsym.h: Forward-declare struct dynamic_prop.
(struct context_stack): Add a static_link field.
(finish_block): Add a static link argument.
* c-exp.y: Remove an obsolete comment (evaluation of variables
already start from the selected frame, and now they climb *up*
the call stack) and propagate the block information to the
produced expression.
* d-exp.y: Likewise.
* f-exp.y: Likewise.
* go-exp.y: Likewise.
* jv-exp.y: Likewise.
* m2-exp.y: Likewise.
* p-exp.y: Likewise.
* coffread.c (coff_symtab_read): Update calls to finish_block.
* dbxread.c (process_one_symbol): Likewise.
* xcoffread.c (read_xcoff_symtab): Likewise.
* compile/compile-c-symbols.c (convert_one_symbol): Promote the
"sym" parameter to struct block_symbol, update its uses and pass
its block to calls to read_var_value.
(convert_symbol_sym): Update the calls to convert_one_symbol.
* compile/compile-loc2c.c (do_compile_dwarf_expr_to_c): Update
call to read_var_value.
* dwarf2loc.c (block_op_get_frame_base): New.
(dwarf2_block_frame_base_locexpr_funcs): Implement the
get_frame_base method.
(dwarf2_block_frame_base_loclist_funcs): Likewise.
(dwarf2locexpr_baton_eval): Add a frame argument and use it
instead of the selected frame in order to evaluate the
expression.
(dwarf2_evaluate_property): Add a frame argument. Update call
to dwarf2_locexpr_baton_eval to provide a frame in available and
to handle the absence of address stack.
* dwarf2loc.h (dwarf2_evaluate_property): Add a frame argument.
* dwarf2read.c (attr_to_dynamic_prop): Add a forward
declaration.
(read_func_scope): Record any available static link description.
Update call to finish_block.
(read_lexical_block_scope): Update call to finish_block.
* findvar.c (follow_static_link): New.
(get_hosting_frame): New.
(default_read_var_value): Add a var_block argument. Use
get_hosting_frame to handle non-local references.
(read_var_value): Add a var_block argument and pass it to the
LA_READ_VAR_VALUE method.
* gdbtypes.c (resolve_dynamic_range): Update calls to
dwarf2_evaluate_property.
(resolve_dynamic_type_internal): Likewise.
* guile/scm-frame.c (gdbscm_frame_read_var): Update call to
read_var_value, passing it the block coming from symbol lookup.
* guile/scm-symbol.c (gdbscm_symbol_value): Update call to
read_var_value (TODO).
* infcmd.c (finish_command_continuation): Update call to
read_var_value, passing it the block coming from symbol lookup.
* infrun.c (insert_exception_resume_breakpoint): Likewise.
* language.h (struct language_defn): Add a var_block argument to
the LA_READ_VAR_VALUE method.
