2024-06-12Allow calling of user-defined function call operatorsHannes Domani1-3/+31
Currently it's not possible to call user-defined function call operators, at least not without specifying operator() directly: ``` (gdb) l 1 1 struct S { 2 int operator() (int x) { return x + 5; } 3 }; 4 5 int main () { 6 S s; 7 8 return s(23); 9 } (gdb) p s(10) Invalid data type for function to be called. (gdb) p s.operator()(10) $1 = 15 ``` This now looks if an user-defined call operator is available when trying to 'call' a struct value, and calls it instead, making this possible: ``` (gdb) p s(10) $1 = 15 ``` The change in operation::evaluate_funcall is to make sure the type fields are only used for function types, only they use them as the argument types.

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.

2024-02-26Remove two unnecessary castsTom Tromey1-1/+1
I noticed a spot in ada-lang.c where the return value of value_as_address was cast to CORE_ADDR -- a no-op cast. I searched and found another. This patch fixes both.
2024-02-05Handling of arrays with optimized-out boundsTom Tromey1-1/+1
In Ada, sometimes the compiler must emit array bounds by referencing an artificial variable that's created for this purpose. However, with optimization enabled, these variables can be optimized away. Currently this can result in displays like: (gdb) print mumble $1 = (warning: unable to get bounds of array, assuming null array ) This patch changes this to report that the array is optimized-out, instead, which is closer to the truth, and more generally useful. For example, Python pretty-printers can now recognize this situation. In order to accomplish this, I introduced a new PROP_OPTIMIZED_OUT enumerator and changed one place to use it. Reusing the "unknown" state wouldn't work properly, because in C it is normal for array bounds to be unknown.
2024-02-02gdb, testsuite, fortran: Fix sizeof intrinsic for Fortran pointersNils-Christian Kempke1-0/+7
For Fortran pointers gfortran/ifx emits DW_TAG_pointer_types like <2><17d>: Abbrev Number: 22 (DW_TAG_variable) <180> DW_AT_name : (indirect string, offset: 0x1f1): fptr <184> DW_AT_type : <0x214> ... <1><219>: Abbrev Number: 27 (DW_TAG_array_type) <21a> DW_AT_type : <0x10e> <216> DW_AT_associated : ... The 'pointer property' in Fortran is implicitly modeled by adding a DW_AT_associated to the type of the variable (see also the DW_AT_associated description in DWARF 5). A Fortran pointer is more than an address and thus different from a C pointer. It is a self contained type having additional fields such as, e.g., the rank of its underlying array. This motivates the intended DWARF modeling of Fortran pointers via the DW_AT_associated attribute. This patch adds support for the sizeof intrinsic by simply dereferencing pointer types when encountered during a sizeof evaluation. The patch also adds a test for the sizeof intrinsic which was not tested before. Tested-by: Thiago Jung Bauermann <thiago.bauermann@linaro.org> Approved-By: Tom Tromey <tom@tromey.com>
2024-01-28Use domain_search_flags in lookup_symbol et alTom Tromey1-2/+3
This changes lookup_symbol and associated APIs to accept domain_search_flags rather than a domain_enum. Note that this introduces some new constants to Python and Guile. I chose to break out the documentation patch for this, because the internals here do not change until a later patch, and it seemed simpler to patch the docs just once, rather than twice.
2024-01-19gdb: remove SYMBOL_*_OPS macrosSimon Marchi1-3/+4
Remove SYMBOL_BLOCK_OPS, SYMBOL_COMPUTED_OPS and SYMBOL_REGISTER_OPS, in favor of methods on struct symbol. More changes could be done here to improve the design and make things safer, but I just wanted to do a straightforward change to remove the macros for now.

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.
2023-12-14gdb: change value_of_register and value_of_register_lazy to take the next frameSimon Marchi1-1/+2
Some functions related to the handling of registers in frames accept "this frame", for which we want to read or write the register values, while other functions accept "the next frame", which is the frame next to that. The later is needed because we sometimes need to read register values for a frame that does not exist yet (usually when trying to unwind that frame-to-be). value_of_register and value_of_register_lazy both take "this frame", even if what they ultimately want internally is "the next frame". This is annoying if you are in a spot that currently has "the next frame" and need to call one of these functions (which happens later in this series). You need to get the previous frame only for those functions to get the next frame again. This is more manipulations, more chances of mistake. I propose to change these functions (and a few more functions in the subsequent patches) to operate on "the next frame". Things become a bit less awkward when all these functions agree on which frame they take. So, in this patch, change value_of_register_lazy and value_of_register to take "the next frame" instead of "this frame". This adds a lot of get_next_frame_sentinel_okay, but if we convert the user registers API to also use "the next frame" instead of "this frame", it will get simple again.

2023-11-29Use C++17 [[fallthrough]] attributeTom Tromey1-1/+1
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. I suspect this fixes the bug mentioned below, by switching to a standard approach that, presumably, clang supports.

2023-11-21gdb: Use std::string_view instead of gdb::string_viewLancelot Six1-0/+1
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.

2023-11-21gdb: Replace gdb::optional with std::optionalLancelot Six1-1/+1
Since GDB now requires C++17, we don't need the internally maintained gdb::optional implementation. This patch does the following replacing: - gdb::optional -> std::optional - gdb::in_place -> std::in_place - #include "gdbsupport/gdb_optional.h" -> #include <optional> This change has mostly been done automatically. One exception is gdbsupport/thread-pool.* which did not use the gdb:: prefix as it already lives in the gdb namespace.

2023-03-27Simplify binop_promoteTom Tromey1-36/+19
binop_promote currently only handles integer sizes up to builtin_long_long. However, this may not handle 128-bit types. Simplify this code, unify the C and non-C (but not OpenCL, as I don't know how to test this) cases, and handle 128-bit integers as well. This still doesn't exactly follow C or C++ rules. This could be implemented, but if so, I think it makes more sense as a C-specific expression node.
