2024-03-26gdb, gdbserver, gdbsupport: remove includes of early headersSimon Marchi1-1/+0
Now that defs.h, server.h and common-defs.h are included via the `-include` option, it is no longer necessary for source files to include them. Remove all the inclusions of these files I could find. Update the generation scripts where relevant. Change-Id: Ia026cff269c1b7ae7386dd3619bc9bb6a5332837 Approved-By: Pedro Alves <pedro@palves.net>
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.

2021-02-02gdb/dwarf: few fixes for handling DW_FORM_{rng,loc}listxSimon Marchi1-1/+4
We hit an assertion when loading the binary from PR 26813. When fixing it, execution goes a up bit further but then hits another assert, and another, and another. With these fours fixes, I am able to load the binary and get to the prompt. An error is shown (index pointing outside of the section), because the DW_FORM_rnglistx attribute is not read correctly, but that one is taken care of by the next patch. The four fixes are: - attribute::form_requires_reprocessing needs to handle forms DW_FORM_rnglistx and DW_FORM_loclistx, because set_unsigned_reprocess is called for them in read_attribute_value. - read_attribute_reprocess must call set_unsigned for them, not set_address. The parameter of set_address is a CORE_ADDR, meaning it's for program addresses. Post-reprocess, DW_FORM_rnglistx and DW_FORM_loclistx are offsets into their respective sections (.debug_rnglists and .debug_loclists). set_unsigned is the current attribute value setter that fits the best. But perhaps we should have a setter that takes a sect_offset? - read_attribute_process must call as_unsigned_reprocess instead of as_unsigned to get the pre-reprocess value, otherwise we hit the assert inside as_unsigned that makes sure the attribute doesn't need reprocessing. - attribute::set_unsigned needs to clear the requires_reprocessing flag, otherwise it stays set when reprocessing DW_FORM_rnglistx and DW_FORM_loclistx attributes. There's another assert that we hit once the next patch is applied, but since it's in the same vein as the changes in this patch, I included it in this patch: - attribute::form_is_unsigned must handle form DW_FORM_loclistx, otherwise we hit the assert when trying to call set_unsigned for an attribute of this form. DW_FORM_rnglistx is already handled. gdb/ChangeLog: PR gdb/26813 * dwarf2/attribute.h (struct attribute) <set_unsigned>: Clear requires_reprocessing flag. * dwarf2/attribute.c (attribute::form_is_unsigned): Handle DW_FORM_loclistx.

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-1/+1
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

Now it correctly respects the form of the attribute. gdb/ChangeLog 2020-09-29 Tom Tromey <tom@tromey.com> * dwarf2/read.c (is_valid_DW_AT_defaulted): Move to attribute.c. (dwarf2_add_member_fn): Update. * dwarf2/attribute.h (struct attribute) <defaulted>: Declare. * dwarf2/attribute.c (attribute::defaulted): New method, from is_valid_DW_AT_defaulted.
2020-09-29Remove DW_ADDRTom Tromey1-0/+3
This removes DW_ADDR in favor of accessor methods. gdb/ChangeLog 2020-09-29 Tom Tromey <tom@tromey.com> * dwarf2/read.c (read_attribute_reprocess, read_attribute_value) (dwarf2_const_value_attr, dump_die_shallow) (dwarf2_fetch_constant_bytes): Update. * dwarf2/attribute.h (struct attribute) <form_is_ref>: Update comment. <set_address>: New method. (DW_ADDR): Remove. * dwarf2/attribute.c (attribute::form_is_ref): Update comment. (attribute::as_string, attribute::as_address): Add assert.
2020-09-29Add reprocessing flag to struct attributeTom Tromey1-0/+14
Some forms require "reprocessing" -- a second pass to update their value appropriately. In this case, we'll set the unsigned value on the attribute, and then later set it to the correct value. To handle this, we introduce a reprocessing flag to attribute. Then, we manage this flag to ensure that setting and unsetting is done properly. gdb/ChangeLog 2020-09-29 Tom Tromey <tom@tromey.com> * dwarf2/read.c (read_cutu_die_from_dwo): Use OBSTACK_ZALLOC. (read_attribute_reprocess, read_attribute_value): Update. (read_attribute): Clear requires_reprocessing. * dwarf2/attribute.h (struct attribute) <as_unsigned_reprocess, form_requires_reprocessing>: New methods. <string_init>: Clear requires_reprocessing. <set_unsigned_reprocess>: New method. <name>: Shrink by one bit. <requires_reprocessing>: New member. * dwarf2/attribute.c (attribute::form_requires_reprocessing): New method.
2020-09-29Use setter for attribute's unsigned valueTom Tromey1-0/+23
This adds form_is_unsigned and an unsigned setter method to struct attribute, and updates the remaining code. Now DW_UNSND is no longer used as an lvalue. gdb/ChangeLog 2020-09-29 Tom Tromey <tom@tromey.com> * dwarf2/read.c (read_attribute_value): Update. * dwarf2/attribute.h (struct attribute) <form_is_unsigned, set_unsigned>: New methods. * dwarf2/attribute.c (attribute::form_is_unsigned): New method.
2020-09-29Remove DW_BLOCKTom Tromey1-1/+2
This removes the DW_BLOCK accessor in favor of methods on struct attribute. The methods, unlike the access, check the form. Note that DW_FORM_data16 had to be handled by form_is_block, because in practice that is how we store values of this form. gdb/ChangeLog 2020-09-29 Tom Tromey <tom@tromey.com> * dwarf2/read.c (read_call_site_scope) (handle_data_member_location, dwarf2_add_member_fn) (mark_common_block_symbol_computed, attr_to_dynamic_prop) (partial_die_info::read, read_attribute_value) (var_decode_location, dwarf2_const_value_attr, dump_die_shallow) (dwarf2_fetch_die_loc_sect_off, dwarf2_fetch_constant_bytes) (dwarf2_symbol_mark_computed): Update. * dwarf2/attribute.h (struct attribute) <as_block, set_block>: New methods. (DW_BLOCK): Remove. * dwarf2/attribute.c (attribute::form_is_block): Add DW_FORM_data16.
2020-09-29Remove DW_STRING and DW_STRING_IS_CANONICALTom Tromey1-9/+17
This removes DW_STRING and DW_STRING_IS_CANONICAL, replacing them with accessor methods on struct attribute. The new code ensures that a string value will only ever be used when the form allows it. gdb/ChangeLog 2020-09-29 Tom Tromey <tom@tromey.com> * dwarf2/read.c (read_cutu_die_from_dwo) (read_attribute_reprocess, read_attribute_value, read_attribute) (dwarf2_const_value_attr, dwarf2_name, dump_die_shallow) (dwarf2_fetch_constant_bytes): Update. * dwarf2/attribute.h (struct attribute) <form_is_string>: Declare. <set_string_noncanonical, set_string_canonical>: New methods. <string_is_canonical>: Update comment. <canonical_string_p>: Add assert. (DW_STRING, DW_STRING_IS_CANONICAL): Remove. * dwarf2/attribute.c (attribute::form_is_string): New method. (attribute::string): Use it.
2020-09-29Avoid using DW_* macros in dwarf2/attribute.cTom Tromey1-5/+5
There's no need to use the DW_* accessor macros in dwarf2/attribute.c, and this is a necessary step toward our goal of removing them entirely. gdb/ChangeLog 2020-09-29 Tom Tromey <tom@tromey.com> * dwarf2/attribute.c (attribute::address): Don't use DW_UNSND or DW_ADDR. (attribute::string): Don't use DW_STRING. (attribute::get_ref_die_offset): Don't use DW_UNSND. (attribute::constant_value): Don't use DW_UNSND or DW_SND.
2020-09-29Rename struct attribute accessorsTom Tromey1-2/+2
This removes the "value_" prefix from the struct value accessors. This seemed unnecessarily wordy to me. gdb/ChangeLog 2020-09-29 Tom Tromey <tom@tromey.com> * dwarf2/read.c (dwarf2_find_base_address, read_call_site_scope) (dwarf2_get_pc_bounds, dwarf2_record_block_ranges) (partial_die_info::read, dwarf2_string_attr, new_symbol): Update. * dwarf2/attribute.h (struct attribute): Rename methods. * dwarf2/attribute.c (attribute::as_address): Rename from value_as_address. (attribute::as_string): Rename from value_as_string.
2020-05-27Attribute method inliningTom Tromey1-27/+2
This inlines a couple of methods on struct attribute, improving the performance of DWARF partial symbol reading. These methods were discovered as hot spots using callgrind. For this patch, and for all the patches in this series, I tested gdb's performance on three programs: 1. gdb itself -- I built gdb and copied it to /tmp, ensuring that the same version was used in all tests. 2. The system libxul.so, the main library of Firefox. I installed the separate debuginfo and ensured that gdb read it. 3. A large-ish Ada program that I happen to have. I ran gdb 10 times like: /bin/time -f %e \ ./gdb/gdb --data-directory ./gdb/data-directory -nx \ -iex 'set debug-file-directory /usr/lib/debug' \ -batch $X ... where $X was the test executable. Then I computed the mean time. This was all done with a standard (-g -O2) build of gdb. The baseline times were gdb 1.90 libxul 2.12 Ada 2.61 This patch brings the numbers down to gdb 1.88 libxul 2.11 Ada 2.60 Not a huge change, but still visible in the results. gdb/ChangeLog 2020-05-27 Tom Tromey <tromey@adacore.com> * dwarf2/attribute.h (struct attribute) <form_is_ref>: Inline. <get_ref_die_offset>: Inline. <get_ref_die_offset_complaint>: New method. * dwarf2/attribute.c (attribute::form_is_ref): Move to header. (attribute::get_ref_die_offset_complaint): Rename from get_ref_die_offset. Just issue complaint.
2020-04-24Add attribute::value_as_string methodTom Tromey1-0/+18
The full DIE reader checks that an attribute has a "string" form in some spots, but the partial DIE reader does not. This patch brings the two readers in sync for one specific case, namely when examining the linkage name. This avoids regressions in an existing DWARF test case. A full fix for this problem would be preferable. An accessor like DW_STRING should always check the form. However, I haven't attempted that in this series. Also the fact that the partial and full readers can disagree like this is a design flaw. gdb/ChangeLog 2020-04-24 Tom Tromey <tom@tromey.com> * dwarf2/read.c (partial_die_info::read) <case DW_AT_linkage_name>: Use value_as_string. (dwarf2_string_attr): Use value_as_string. * dwarf2/attribute.h (struct attribute) <value_as_string>: Declare method. * dwarf2/attribute.c (attribute::value_as_string): New method.

2020-03-26Change two functions to be methods on struct attributeTom Tromey1-0/+37
This changes dwarf2_get_ref_die_offset and dwarf2_get_attr_constant_value to be methods on struct attribute. gdb/ChangeLog 2020-03-26 Tom Tromey <tom@tromey.com> * dwarf2/read.c (handle_data_member_location, dwarf2_add_field) (mark_common_block_symbol_computed, read_tag_string_type) (attr_to_dynamic_prop, read_subrange_type): Update.

(skip_one_die, process_imported_unit_die, read_namespace_alias) (read_call_site_scope, partial_die_info::read) (partial_die_info::read, lookup_die_type, follow_die_ref): Update. * dwarf2/attribute.c (attribute::get_ref_die_offset): New method, from dwarf2_get_ref_die_offset. (attribute::constant_value): New method, from dwarf2_get_attr_constant_value. * dwarf2/attribute.h (struct attribute) <get_ref_die_offset>: Declare method. <constant_value>: New method.
2020-02-08Change attr_form_is_block to be a methodTom Tromey1-8/+7
This changes attr_form_is_block to be a method. This is done separately because, unlike the other attribute functions, attr_form_is_block had special handling for the case where the argument was NULL. This required auditing each call site; in most cases, NULL was already ruled out, but in a few spots, an additional check was needed. gdb/ChangeLog 2020-02-08 Tom Tromey <tom@tromey.com> * dwarf2read.c (read_call_site_scope) (handle_data_member_location, dwarf2_add_member_fn) (mark_common_block_symbol_computed, read_common_block) (attr_to_dynamic_prop, partial_die_info::read) (var_decode_location, dwarf2_fetch_die_loc_sect_off) (dwarf2_symbol_mark_computed, set_die_type): Update. * dwarf2/attribute.h (struct attribute) <form_is_block>: Declare method. (attr_form_is_block): Don't declare. * dwarf2/attribute.c (attribute::form_is_block): Now a method. Change-Id: Idfb290c61d738301ab991666f43e0b9cf577b2ae
2020-02-08Change some attribute functions to be methodsTom Tromey1-20/+20

2020-02-08Create dwarf2/attribute.[ch]Tom Tromey1-0/+122
This moves the attribute-related code out of dwarf2read.c and into the new files dwarf2/attribute.[ch]. gdb/ChangeLog 2020-02-08 Tom Tromey <tom@tromey.com> * dwarf2read.c (struct attribute, DW_STRING) (DW_STRING_IS_CANONICAL, DW_UNSND, DW_BLOCK, DW_SND, DW_ADDR) (DW_SIGNATURE, struct dwarf_block, attr_value_as_address) (attr_form_is_block, attr_form_is_section_offset) (attr_form_is_constant, attr_form_is_ref): Move. * dwarf2/attribute.h: New file. * dwarf2/attribute.c: New file, from dwarf2read.c. * Makefile.in (COMMON_SFILES): Add dwarf2/attribute.c.
