Simon Marchi	b3b3bada0d	gdb: introduce objfile text_section_offset and data_section_offset methods The pattern objfile->section_offsets[SECT_OFF_TEXT (objfile)] ... appears very often, to get the offset of the text section of an objfile. I thought it would be more readable to write it as: objfile->text_section_offset () ... so I added this method and used it where possible. I also added data_section_offset, although it is not used as much. gdb/ChangeLog: * objfiles.h (ALL_OBJFILE_OSECTIONS): Move up. (SECT_OFF_DATA): Likewise. (SECT_OFF_RODATA): Likewise.

Simon Marchi	6c2659886f	gdb: add back declarations for _initialize functions 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 `481695ed5f` 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

Tom Tromey	6a053cb1ff	Change section_offsets to a std::vector 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.

Tom Tromey	e0eac551da	Remove some includes of readline.h I went through most of the spots that include readline.h and, when appropriate, either removed the include or changed it to include tilde.h. Note that remote-sim.c and bsd-kvm.c could probably include tilde.h instead, but I did not change these. I think I can't build the latter, and I didn't want to set up a sim build for the former. Tested by rebuilding. gdb/ChangeLog 2019-11-06 Tom Tromey <tom@tromey.com> * tui/tui-interp.c: Don't include readline.h. * tui/tui-hooks.c: Don't include readline.h. * symmisc.c: Include tilde.h, not readline.h. * symfile.c: Include tilde.h, not readline.h. * source.c: Include tilde.h, not readline.h. * solib.c: Include tilde.h, not readline.h. * psymtab.c: Include tilde.h, not readline.h. * exec.c: Include tilde.h, not readline.h. * corelow.c: Include tilde.h, not readline.h. * cli/cli-dump.c: Include tilde.h, not readline.h. * cli/cli-cmds.c: Don't include readline.h.

Andrew Burgess	59c35742fb	gdb/fortran: Add new 'info modules' command Add a new command 'info modules' that lists all of the modules GDB knows about from the debug information. A module is a debugging entity in the DWARF defined with DW_TAG_module, currently Fortran is known to use this tag for its modules. I'm not aware of any other language that currently makes use of DW_TAG_module. The output style is similar to the 'info type' output: (gdb) info modules All defined modules: File info-types.f90: 16: mod1 24: mod2 (gdb) Where the user is told the file the module is defined in and, on the left hand side, the line number at which the module is defined along with the name of the module. This patch is a new implementation of an idea originally worked on by Mark O'Connor, Chris January, David Lecomber, and Xavier Oro from ARM. gdb/ChangeLog: * dwarf2read.c (dw2_symtab_iter_next): Handle MODULE_DOMAIN.

Christian Biesinger	31edb80295	Change some arguments to gdb::string_view instead of name+len 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.

Andrew Burgess	3dd9bb4620	gdb: Don't fault for 'maint print psymbols' when using an index I found that these tests: make check-gdb RUNTESTFLAGS="--target_board=cc-with-gdb-index gdb.base/maint.exp" make check-gdb RUNTESTFLAGS="--target_board=cc-with-debug-names gdb.base/maint.exp" were causing GDB to segfault. It turns out that this test runs this command: maint print psymbols -pc main /path/to/some/file which tries to lookup the partial_symtab for 'main'. The problem is that there is no partial_symtab for 'main' as we are using the .gdb_index or .debug_names instead of partial_symtabs. What happens is that maintenance_print_symbols calls find_pc_sect_psymtab, which looks for the partial_symtab in the objfile's objfile->partial_symtabs->psymtabs_addrmap. This is a problem because when we are using the indexes psymtabs_addrmap is reused to hold things other than partial_symtabs, this can be seen in dwarf2read.c in create_addrmap_from_index and create_addrmap_from_aranges. If we then lookup in psymtabs_addrmap we end up returning a pointer to something that isn't really a partial_symtab, after which everything goes wrong. Initially I simply added a check at the start of find_pc_sect_psymtab that the objfile had some partial_symtabs, like: if (objfile->partial_symtabs->psymtabs == NULL) return NULL; Figuring that if there were no partial_symtabs at all then this function should always return NULL, however, this caused a failure in the test gdb.python/py-event.exp which I didn't dig into too deeply, but seems to be that in this tests there are initially no psymtabs, but the second part of find_pc_sect_psymtab does manage to read some in from somewhere, with the check I added the test fails as we returned NULL here and this caused GDB to load in the full symtabs earlier than was expected. Instead I chose to guard only the access to psymtabs_addrmap with a check that the function has some psymtabs. This allows my original tests to pass, and the py-event.exp test to pass too. Now, a good argument can be made that we simply should never call find_pc_sect_psymtab on an objfile that is using indexes instead of partial_symtabs. I did consider this approach, we could easily add an assert into find_pc_sect_psymtab that if we find a partial_symtab in psymtabs_addrmap then the psymtabs pointer must be non-null. The responsibility would then be on the user of find_pc_sect_psymtab to ensure that the objfile being checked is suitable. In the end I didn't take this approach as the check in find_pc_sect_psymtab is cheap and this ensures that any future miss-uses of the function will not cause problems. I also extended the comment on psymtabs_addrmap to indicate that it holds more than just partial_symtabs as this was not at all clear from the original comment, and caused me some confusion when I was initially debugging this problem. gdb/ChangeLog: * psymtab.c (find_pc_sect_psymtab): Move baseaddr local into more inner scope, add check that the objfile has psymtabs before checking psymtabs_addrmap. * psymtab.h (psymtab_storage) <psymtabs_addrmap>: Extend comment.	2019-09-12 20:31:29 -04:00

Note: I tried to put this in common/common-utils.h near skip_spaces, etc. but that is included in common/common-defs.h before common/gdb_unique_ptr.h is included, so it would fail to compile because gdb::unique_xmalloc_ptr isn't defined at that point yet.

Tom Tromey	af97b4161f	Don't derive partial_symbol from general_symbol_info This patch partly reverts commit `8a6d42345` ("Change representation of psymbol to flush out accessors"); specifically, it changes partial_symbol to no longer derive from general_symbol_info. The basic problem here is that the bcache compares objects bitwise, and this change made it less likely that the relevant fields in the psymbol would be fully initialized. This could be seen by running a test under valgrind on the Fedora-i686 buildbot. I considered a simpler patch, namely just zeroing the psymbol's "value" field in add_psymbol_to_bcache. However, it wasn't clear to me that this memset could not then be optimized away by the compiler. Regression tested by the buildbot.

Tom Tromey	8d7bcccb82	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.

Tom Tromey	5923a04c0c	Allocate the address map on the psymtab obstack After this patch, the psymtab address map will now be allocated on the psymtab obstack rather than the objfile obstack. This also changes the psymtab storage object to make the obstack private; this will be used later. gdb/ChangeLog 2019-01-10 Tom Tromey <tom@tromey.com> * psymtab.h (psymtab_storage::obstack): New method. <m_obstack>: Rename from obstack; now private. * psymtab.c (psymtab_storage): Update. * dwarf2read.c (create_addrmap_from_index) (create_addrmap_from_aranges, dwarf2_build_psymtabs_hard): Update.	2019-01-10 07:08:13 -07:00
Tom Tromey	d320c2b5e1	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.

Tom Tromey	3453e7e409	Clean up "Reading symbols" output This patch is another attempt to fix PR cli/19551. Unlike my previous attempt, it doesn't print progress. Instead, it just changes some messages and adds newlines to make the output a bit nicer. It also removes the "done." text that was previously emitted. The idea here is that it is obvious when gdb is done reading debug info, as it starts then doing something else; and that while this message did not provide much benefit to users, it did make it harder to make the output clean.

Tom Tromey	22068491ad	Use filtered printing when reading symbols While working on this series, I found some unfiltered prints that didn't make sense -- many things, like complaints, are filtered, while their context (in this case the "Reading symbols ..." messages) may not be. This patch changes some spots in symbol reading to use filtered prints. I think this is preferable overall; in fact I'd go farther and say that unfiltered printing should just be removed. One of these spots was not strictly related (the change to dump_psymtab), but I left it in partly because it makes psymtab.c "unfiltered-clean", and partly because it is an example of filtered and unfiltered printing being mixed in the same function. gdb/ChangeLog 2018-10-04 Tom Tromey <tom@tromey.com> * symfile.c (symbol_file_add_with_addrs, symbol_file_clear) (separate_debug_file_exists, find_separate_debug_file) (add_symbol_file_command, reread_symbols, allocate_symtab) (allocate_compunit_symtab): Use filtered printing, not unfiltered. * psymtab.c (require_partial_symbols, dump_psymtab) (allocate_psymtab): Use filtered printing, not unfiltered.	2018-10-04 13:40:10 -06:00
Tom Tromey	7974897237	Make psymbols and psymtabs independent of the program space This patch finally makes partial symbols and partial symtabs independent of the program space. Specifically: It changes add_psymbol_to_list to accept a section index, and changes the psymbol readers to pass this. At the same time it removes the code to add the objfile's section offset to the psymbol. It adds an objfile argument to the psymtab textlow and texthigh accessors and changes some code to use the raw variants instead. It removes the "relocate" method from struct quick_symbol_functions, as it is no longer needed any more. It changes partial_symbol::address so that the relevant offset is now applied at the point of use. gdb/ChangeLog 2018-07-26 Tom Tromey <tom@tromey.com> * dwarf-index-write.c (add_address_entry): Don't add objfile offsets. * dbxread.c (find_stab_function): Rename from find_stab_function_addr.

Tom Tromey	4ae976d1df	Introduce accessors for psymtab high and low fields This introduces accessors for the partial symbol table textlow and texthigh fields. This lets us later arrange to relocate these values at their point of use. I did this conversion by renaming the fields. I didn't rename the fields back afterward, thinking that on the off chance that someone has a patch touching this area, then a merge would helpfully break their compile. I looked at making the fields private, but this interferes with the memset in allocate_psymtab, and I didn't want to chase this down. This conversion can be done later if need be. gdb/ChangeLog 2018-07-26 Tom Tromey <tom@tromey.com> * dbxread.c (read_dbx_symtab, end_psymtab, read_ofile_symtab): Update. * dwarf2read.c (dwarf2_create_include_psymtab): Don't initialize textlow and texthigh fields.

Tom Tromey	02e9e7f7e2	Introduce partial_symbol::address This introduces a partial_symbol::address method. This method takes an objfile argument. This is necessary so that we can later relocate a partial symbol at its point of use. It also adds an accessor to compute the unrelocated value; and a method to be used for setting the field. Note that the new method doesn't actually perform any relocation yet. That will come in a subsequent patch. However, the comments are written to reflect the intended, rather than the temporary, semantics. gdb/ChangeLog 2018-07-26 Tom Tromey <tromey@redhat.com> * psympriv.h (struct partial_symbol) <unrelocated_address, address, set_address>: New methods. * psymtab.c (find_pc_sect_psymtab_closer, find_pc_sect_psymbol) (fixup_psymbol_section, relocate_psymtabs): Update.

Tom Tromey	8a6d423450	Change representation of psymbol to flush out accessors This is the psymbol analog to the patch to change the representation of minimal symbols: https://sourceware.org/ml/gdb-patches/2013-10/msg00524.html It has the same rationale: namely, that we're going to change the code to apply psymbol offsets at runtime. This will be done by adding an argument to the SYMBOL_VALUE_ADDRESS macro -- but since we can't convert all the symbol types at once, we need a new approach. Because gdb now is in C++, this patch changes partial_symbol to inherit from general_symbol_info, rather than renaming the field. This simplifies code in some places. Also, as noted before, these macros implement a kind of "phony polymorphism" that is not actually useful in practice; so this patch removes the macros in favor of simply referring directly to members. In a few cases -- obj_section in this patch and the symbol address in the future -- methods will be used instead. Note that this removes the blanket memset from add_psymbol_to_bcache. This hasn't really been needed since bcache was modified to allow holes in objects and since psymtab took advantage of that. This deletion was required due to changing partial_symbol to derive from general_symbol_info. gdb/ChangeLog 2018-07-26 Tom Tromey <tom@tromey.com> * dwarf-index-write.c (write_psymbols, debug_names::insert) (debug_names::write_psymbols): Update. * psympriv.h (struct partial_symbol): Derive from general_symbol_info. <obj_section>: New method.
