2023-09-25arc: Update bfd arc pattern file to allow enable-targets=allClaudiu Zissulescu1-5/+9
The ARC backend uses a BFD pattern file to generate three ARC targets: - an BFD ARC target for ARCv1 and ARCv2 CPU families. It also works for big-endian variants. - an BFD ARC64 target for ARCv3 64bit machines. It also allows working with ARCv3 32bit machines. - an BFD ARC32 target for ARCv4 32bit machines. It also allows working with ARCv3 64bit machines. When configuring with `--enable-targets=all` some patterns are defined multiple times. Fix this issue.

2023-09-25arc: Update ARC's Gnu Assembler backend with ARCv3 ISA.Claudiu Zissulescu6-241/+563
The new Synopsys ARCv3 ISA has a similar instruction format like the old ARCv1 and ARCv2 ISA. Thus, the ARCv3 addition is using whatever we have for old ARC processors plus some ARCv3 spcific mods. To distinguish between various ARC variants, we introduced two new configure defines named TARGET_ARCv3_32 and TARGET_ARCv3_64 which are set when we choose either an ARC32 (ARCv3/32) ISA toolchain or an ARC64 (ARCv3/64) ISA toolchain. gas/ xxxx-xx-xx Claudiu Zissulescu <claziss@synopsys.com> * gas/config/tc-arc.h: Selectively define default target macros. * gas/configure.ac: Add ARC64 target. * gas/configure.tgt: Likewise. * gas/configure: Regenerate * gas/config.in: Regenerate. * gas/config/tc-arc.c (DEFAULT_ARCH): New macro.

2023-09-22Remove keywords from target debug printer namesTom Tromey3-85/+86
I recently checked in a patch that removed the use of the "struct" keyword in some spots. Doing this pointed out that the target delegate code preserves this keyword -- but, with C++, it does not really need to. This patch changes make-target-delegates.py to remove these keywords, and updates target-debug.h to follow. This pointed out that there was already one redudancy: both target_debug_print_struct_inferior_p and target_debug_print_inferior_p existed. Tested by rebuilding.

2023-09-20gdb/dap: only include sourceReference if file path does not existGregory Anders2-9/+16
According to the DAP specification if the "sourceReference" field is included in a Source object, then the DAP client _must_ make a "source" request to the debugger to retrieve file contents, even if the Source object also includes path information. If the Source's path field is a valid path that the DAP client is able to read from the filesystem, having to make another request to the debugger to get the file contents is wasteful and leads to incorrect results (DAP clients will try to get the contents from the server and display those contents as a file with the name in "source.path", but this will conflict with the _acutal_ existing file at "source.path"). Instead, only set "sourceReference" if the source file path does not exist. Approved-By: Tom Tromey <tom@tromey.com>
2023-09-20gdb/dap: use breakpoint fullname to resolve sourceGregory Anders1-3/+3

2023-09-20gdb/dap: check for breakpoint source before unpackingGregory Anders2-8/+19
Not all breakpoints have a source location. For example, a breakpoint set on a raw address will have only the "address" field populated, but "source" will be None, which leads to a RuntimeError when attempting to unpack the filename and line number. Before attempting to unpack the filename and line number from the breakpoint, ensure that the source information is not None. Also populate the source and line information separately from the "instructionReference" field, so that breakpoints that include only an address are still included.

2023-09-20gdb/tui: add 'set tui mouse-events off' to restore mouse selectionMatthew "strager" Glazar6-2/+52
Rationale: I use the mouse with my terminal to select and copy text. In gdb, I use the mouse to select a function name to set a breakpoint, or a variable name to print, for example. When gdb is compiled with ncurses mouse support, gdb's TUI mode intercepts mouse events. Left-clicking and dragging, which would normally select text, seems to do nothing. This means I cannot select text using my mouse anymore. This makes it harder to set breakpoints, print variables, etc. Solution: I tried to fix this issue by editing the 'mousemask' call to only enable buttons 4 and 5. However, this still caused my terminal (gnome-terminal) to not allow text to be selected. The only way I could make it work is by calling 'mousemask (0, NULL);'. But doing so disables the mouse code entirely, which other people might want. I therefore decided to make a setting in gdb called 'tui mouse-events'. If enabled (the default), the behavior is as it is now: terminal mouse events are given to gdb, disabling the terminal's default behavior. If disabled (opt-in), the behavior is as it was before the year 2020: terminal mouse events are not given to gdb, therefore the mouse can be used to select and copy text. Notes: I am not attached to the setting name or its description. Feel free to suggest better wording. Testing: I tested this change in gnome-terminal by performing the following steps manually: 1. Run: gdb --args ./myprogram 2. Enable TUI: press ctrl-x ctrl-a 3. Click and drag text with the mouse. Observe no selection. 4. Input: set tui mouse-events off 5. Click and drag text with the mouse. Observe that selection works now. 6. Input: set tui mouse-events on. 7. Click and drag text with the mouse. Observe no selection.
2023-09-20[gdb/symtab] Error out for .debug_types section in dwz fileTom de Vries5-0/+143
There are two methods to factor out type information in a dwarf4 executable: - use -fdebug-info-types to generate type units in a .debug_types section, and - use dwz to create partial units. The dwz method has an extra benefit: it also allows to factor out information between executables into a newly created .dwz file, pointed to by a .gnu_debugaltlink section. There is nothing prohibiting a .gnu_debugaltlink file to contain a .debug_types section. It's just not generated by dwz or any other tool atm, and consequently gdb has no support for it. Enhancement PR symtab/30838 is open about the lack of support. Make the current situation explicit by emitting a dwarf error: ... (gdb) file struct-with-sig-2^M Reading symbols from struct-with-sig-2...^M Dwarf Error: .debug_types section not supported in dwz file^M ... and add an assert in write_gdbindex: ... + /* See enhancement PR symtab/30838. */ + gdb_assert (!(per_cu->is_dwz && per_cu->is_debug_types)); ... to clarify why we can use: ... data_buf &cu_list = (per_cu->is_debug_types ? types_cu_list : per_cu->is_dwz ? dwz_cu_list : objfile_cu_list); ... The test-case is a modified copy from gdb.dwarf2/struct-with-sig.exp, so it keeps the copyright years range. Tested on x86_64-linux.

2023-09-19Handle pointers and references correctly in DAPTom Tromey3-0/+153
A user pointed out that the current DAP variable code does not let the client deference a pointer. Oops! Fixing this oversight is simple enough -- adding a new no-op pretty-printer for pointers and references is quite simple. However, doing this naive caused a regession in scopes.exp, which expected there to be no children of a 'const char *' variable. This problem was fixed by the preceding patches in the series, which ensure that a C type of this kind is recognized as a string. Bug: https://sourceware.org/bugzilla/show_bug.cgi?id=30821
2023-09-19Give a language to a typeTom Tromey9-94/+98
This changes main_type to hold a language, and updates the debug readers to set this field. This is done by adding the language to the type-allocator object. Note that the non-DWARF readers are changed on a "best effort" basis. This patch also reimplements type::is_array_like to use the type's language, and it adds a new type::is_string_like as well. This in turn lets us change the Python implementation of these methods to simply defer to the type.
2023-09-19Add is_array_like and to_array to language_defnTom Tromey3-0/+34
This adds new is_array_like and to_array methods to language_defn. This will be used in a subsequent patch that generalizes the new Python array- and string-handling code.
2023-09-19Regularize some DWARF type initializationTom Tromey1-11/+13
In one spot, it will be convenient for a subsequent patch if the CU is passed to a type-creation helper function. In another spot, remove the redundant 'objfile' parameter to another such function.
2023-09-19Pass a type allocator to init_fixed_point_typeTom Tromey3-5/+5
init_fixed_point_type currently takes an objfile and creates its own type allocator. However, for a later patch it is more convenient if this function accepts a type allocator. This patch makes this change.
2023-09-19Use gdb::checked_static_cast for catchpointsTom Tromey3-7/+9
This replaces some casts to various kinds of catchpoint with checked_static_cast. Approved-By: Simon Marchi <simon.marchi@efficios.com>
2023-09-19Use gdb::checked_static_cast for code_breakpointTom Tromey2-3/+5
This replaces some casts to 'code_breakpoint *' with checked_static_cast. Approved-By: Simon Marchi <simon.marchi@efficios.com>
2023-09-19Use gdb::checked_static_cast for tracepointsTom Tromey10-50/+61
This replaces some casts to 'tracepoint *' with checked_static_cast. Some functions are changed to accept a 'tracepoint *' now, for better type safety. Approved-By: Simon Marchi <simon.marchi@efficios.com>
2023-09-19Use gdb::checked_static_cast for watchpointsTom Tromey3-156/+149
This replaces some casts to 'watchpoint *' with checked_static_cast. In one spot, an unnecessary block is also removed. Approved-By: Simon Marchi <simon.marchi@efficios.com>
2023-09-19gdb, breakpoint: add a destructor to the watchpoint structMohamed Bouhaouel4-0/+83
Make sure to unlink the related breakpoint when the watchpoint instance is deleted. This prevents having a wp-related breakpoint that is linked to a NULL watchpoint (e.g. the watchpoint instance is being deleted when the 'watch' command fails). With the below scenario, having such a left out breakpoint will lead to a GDB hang, and this is due to an infinite loop when deleting all inferior breakpoints. Scenario: (gdb) set can-use-hw-watchpoints 0 (gdb) awatch <SCOPE VAR> Can't set read/access watchpoint when hardware watchpoints are disabled. (gdb) rwatch <SCOPE VAR> Can't set read/access watchpoint when hardware watchpoints are disabled. (gdb) <continue the program until the end> >> HANG << Signed-off-by: Mohamed Bouhaouel <mohamed.bouhaouel@intel.com> Reviewed-by: Bruno Larsen <blarsen@redhat.com>
2023-09-19gdb/cli: fixes to newly added "list ." commandGuinevere Larsen4-25/+28
After the series that added this command was pushed, Pedro mentioned that the news description could easily be misinterpreted, as well as some code and test improvements that should be made. While fixing the test, I realized that code repetition wasn't happening as it should, so I took care of that too.
