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.
2023-12-14gdb: change regcache interface to use array_viewSimon Marchi1-21/+28
Change most of regcache (and base classes) to use array_view when possible, instead of raw pointers. By propagating the use of array_view further, it enables having some runtime checks to make sure the what we read from or write to regcaches has the expected length (such as the one in the `copy(array_view, array_view)` function. It also integrates well when connecting with other APIs already using gdb::array_view. Add some overloads of the methods using raw pointers to avoid having to change all call sites at once (which is both a lot of work and risky). I tried to do this change in small increments, but since many of these functions use each other, it ended up simpler to do it in one shot than having a lot of intermediary / transient changes. This change extends into gdbserver as well, because there is some part of the regcache interface that is shared. Changing the reg_buffer_common interface to use array_view caused some build failures in nat/aarch64-scalable-linux-ptrace.c. That file currently "takes advantage" of the fact that reg_buffer_common::{raw_supply,raw_collect} operates on `void *`, which IMO is dangerous. It uses raw_supply/raw_collect directly on uint64_t's, which I guess is fine because it is expected that native code will have the same endianness as the debugged process. To accomodate that, add some overloads of raw_collect and raw_supply that work on uint64_t. This file also uses raw_collect and raw_supply on `char` pointers. Change it to use `gdb_byte` pointers instead. Add overloads of raw_collect and raw_supply that work on `gdb_byte *` and make an array_view on the fly using the register's size. Those call sites could be converted to use array_view with not much work, in which case these overloads could be removed, but I didn't want to do it in this patch, to avoid starting to dig in arch-specific code. During development, I inadvertently changed reg_buffer::raw_compare's behavior to not accept an offset equal to the register size. This behavior (effectively comparing 0 bytes, returning true) change was caught by the AArch64 SME core tests. Add a selftest to make sure that this raw_compare behavior is preserved in the future.

2023-12-14gdb: use reg_buffer_common throughout gdbsupport/common-regcache.hSimon Marchi1-6/+11
Right now, gdbsupport/common-regcache.h contains two abstractons for a regcache. An opaque type `regcache` (gdb and gdbserver both have their own regcache that is the concrete version of this) and an abstract base class `reg_buffer_common`, that is the base of regcaches on both sides. These abstractions allow code to be written for both gdb and gdbserver, for instance in the gdb/arch sub-directory. However, having two different abstractions is impractical. If some common code has a regcache, and wants to use an operation defined on reg_buffer_common, it can't. It would be better to have just one. Change all instances of `regcache *` in gdbsupport/common-regcache.h to be `reg_buffer_common *`, then fix fallouts. Implementations in gdb and gdbserver now need to down-cast (using gdb::checked_static_cast) from reg_buffer_common to their concrete regcache type. Some of them could be avoided by changing free functions (like regcache_register_size) to be virtual methods on reg_buffer_common. I tried it, it seems to work, but I did not include it in this series to avoid adding unnecessary changes.

2023-11-21gdb: Replace gdb::optional with std::optionalLancelot Six1-2/+2
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.

It helped me during development, catching bugs closer to when they actually happened. Also remove the equivalent gdb_assert in regcache_raw_read_unsigned, since it's checking the same condition a few frames above.

2022-12-09[aarch64] Add TPIDR2 register support for LinuxLuis Machado1-4/+16
With the AArch64 Scalable Matrix Extension we have a new TPIDR2 register, and it will be added to the existing NT_ARM_TLS register set. Kernel patches are being reviewed here: https://lore.kernel.org/linux-arm-kernel/20220818170111.351889-1-broonie@kernel.org/ From GDB's perspective, we handle it in a similar way to the existing TPIDR register. But we need to consider cases of systems that only have TPIDR and systems that have both TPIDR and TPIDR2. With that in mind, the following patch adds the required code to support TPIDR2 and turns the org.gnu.gdb.aarch64.tls feature into a dynamically-generated target description as opposed to a static target description containing only TPIDR. That means we can remove the gdb/features/aarch64-tls.xml file and replace the existing gdb/features/aarch64-tls.c auto-generated file with a new file that dynamically generates the target description containing either TPIDR alone or TPIDR and TPIDR2. In the future, when *BSD's start to support this register, they can just enable it as is being done for the AArch64 Linux target. The core file read/write code has been updated to support TPIDR2 as well. On GDBserver's side, there is a small change to the find_regno function to expose a non-throwing version of it. It always seemed strange to me how find_regno causes the whole operation to abort if it doesn't find a particular register name. The patch moves code from find_regno into find_regno_no_throw and makes find_regno call find_regno_no_throw instead. This allows us to do register name lookups to find a particular register number without risking erroring out if nothing is found. The patch also adjusts the feature detection code for aarch64-fbsd, since the infrastructure is shared amongst all aarch64 targets. I haven't added code to support TPIDR2 in aarch64-fbsd though, as I'm not sure when/if that will happen.
2022-10-19internal_error: remove need to pass __FILE__/__LINE__Pedro Alves1-1/+1
Currently, every internal_error call must be passed __FILE__/__LINE__ explicitly, like: internal_error (__FILE__, __LINE__, "foo %d", var); The need to pass in explicit __FILE__/__LINE__ is there probably because the function predates widespread and portable variadic macros availability. We can use variadic macros nowadays, and in fact, we already use them in several places, including the related gdb_assert_not_reached. So this patch renames the internal_error function to something else, and then reimplements internal_error as a variadic macro that expands __FILE__/__LINE__ itself. The result is that we now should call internal_error like so: internal_error ("foo %d", var); Likewise for internal_warning. The patch adjusts all calls sites. 99% of the adjustments were done with a perl/sed script. The non-mechanical changes are in gdbsupport/errors.h, gdbsupport/gdb_assert.h, and gdb/gdbarch.py.

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-2/+2
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

2020-10-06gdbserver: Remove unused argument in register_data()Shahab Vahedi1-7/+7
The register_data() function in gdbserver/regcache.cc has an input argument called "fetch". This argument is not used by this static function at all. Therefore, it is time to get rid of it. gdbserver/ChangeLog: * regcache.cc (register_data): Remove unused "fetch" argument.

2020-02-20gdbserver: finish turning the target ops vector into a classTankut Baris Aktemur1-2/+2
Now that 'process_stratum_target' has a single field left, namely 'pt' of type 'process_target', and that all the requests to a 'process_stratum_target' are forwarded to 'pt', meld the 'process_target' class into 'process_stratum_target'. This essentially means 1. All the references of the form 'the_target->pt' become 'the_target'. 2. All the uses of the name 'process_target' become 'process_stratum_target'. 3. The platform-specific target op vectors (e.g. linux_target_ops) are removed and instances of their "process target" classes are used instead. gdbserver/ChangeLog: 2020-02-20 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * target.h (struct process_stratum_target): Remove. (class process_target): Rename to ... (class process_stratum_target): ... this. * linux-low.h (class linux_process_target): Derive from 'process_stratum_target'. * linux-low.cc (linux_target_ops): Remove. (initialize_low): Set the_target to the singleton instance of linux_process_target. * lynx-low.h (class lynx_process_target): Derive from 'process_stratum_target'. * lynx-low.cc (lynx_target_ops): Remove.

2020-02-13gdbserver: rename source files to .ccSimon Marchi1-0/+528
For the same reasons outlined in the previous patch, this patch renames gdbserver source files to .cc. I have moved the "-x c++" switch to only those rules that require it. gdbserver/ChangeLog: * Makefile.in: Rename source files from .c to .cc. * %.c: Rename to %.cc. * configure.ac: Rename server.c to server.cc. * configure: Re-generate.
