2024-09-25gdb, gdbserver, python, testsuite: Remove MPX.Schimpe, Christina1-65/+2
GDB deprecated the commands "show/set mpx bound" in GDB 15.1, as Intel listed Intel(R) Memory Protection Extensions (MPX) as removed in 2019. MPX is also deprecated in gcc (since v9.1), the linux kernel (since v5.6) and glibc (since v2.35). Let's now remove MPX support in GDB completely. This includes the removal of: - MPX functionality including register support - deprecated mpx commands - i386 and amd64 implementation of the hooks report_signal_info and get_siginfo_type - tests - and pretty printer. We keep MPX register numbers to not break compatibility with old gdbservers. Approved-By: Felix Willgerodt <felix.willgerodt@intel.com>
2024-06-14gdb/gdbserver: share x86/linux tdesc cachingAndrew Burgess1-21/+5
This commit builds on the previous series of commits to share the target description caching code between GDB and gdbserver for x86/Linux targets. The objective of this commit is to move the four functions (2 each of) i386_linux_read_description and amd64_linux_read_description into the gdb/arch/ directory and combine them so we have just a single copy of each. Then GDB, gdbserver, and the in-process-agent (IPA) will link against these shared functions. One curiosity with this patch is the function x86_linux_post_init_tdesc. On the gdbserver side the two functions amd64_linux_read_description and i386_linux_read_description have some functionality that is not present on the GDB side, there is some additional configuration that is performed as each target description is created, to setup the expedited registers. To support this I've added the function x86_linux_post_init_tdesc. This function is called from the two *_linux_read_description functions, but is implemented separately for GDB and gdbserver. An alternative approach that avoids adding x86_linux_post_init_tdesc would be to have x86_linux_tdesc_for_tid return a non-const target description, then in x86_target::low_arch_setup we could inspect the target description to figure out if it is 64-bit or not, and modify the target description as needed. In the end I think that adding the x86_linux_post_init_tdesc function is the simpler solution. The contents of gdbserver/linux-x86-low.cc have moved to gdb/arch/x86-linux-tdesc-features.c, and gdbserver/linux-x86-tdesc.h has moved to gdb/arch/x86-linux-tdesc-features.h, this change leads to some updates in the #includes in the gdbserver/ directory. This commit also changes how target descriptions are cached. Previously both GDB and gdbserver used static C-style arrays to act as the tdesc cache. This was fine, except for two problems. Either the C-style arrays would need to be placed in x86-linux-tdesc-features.c, which would allow us to use the x86_linux_*_tdesc_count_1() functions to size the arrays for us, or we'd need to hard code the array sizes using separate #defines, which we'd then have to keep in sync with the rest of the code in x86-linux-tdesc-features.c. Given both of these problems I decided a better solution would be to just switch to using a std::unordered_map to act as the cache. This will resize automatically, and we can use the xcr0 value as the key. At first inspection, using xcr0 might seem to be a problem; after all the {i386,amd64}_create_target_description functions take more than just the xcr0 value. However, this patch is only for x86/Linux targets, and for x86/Linux all of the other flags passed to the tdesc creation functions have constant values and so are irrelevant when we consider tdesc caching. For testing I've done the following: - Built on x86-64 GNU/Linux for all targets, and just for the native target, - Build on i386 GNU/Linux for all targets, and just for the native target, - Build on a 64-bit, non-x86 GNU/Linux for all targets, just for the native target, and for targets x86_64-*-linux and i386-*-linux.

2024-06-14gdb/gdbserver: share some code relating to target description creationAndrew Burgess1-0/+1
This commit is part of a series to share more of the x86 target description creation code between GDB and gdbserver. Unlike previous commits which were mostly refactoring, this commit is the first that makes a real change, though that change should mostly be for gdbserver; I've largely adopted the "GDB" way of doing things for gdbserver, and this fixes a real gdbserver bug. On a x86-64 Linux target, running the test: gdb.server/connect-with-no-symbol-file.exp results in two core files being created. Both of these core files are from the inferior process, created after gdbserver has detached. In this test a gdbserver process is started and then, after gdbserver has started, but before GDB attaches, we either delete the inferior executable, or change its permissions so it can't be read. Only after doing this do we attempt to connect with GDB. As GDB connects to gdbserver, gdbserver attempts to figure out the target description so that it can send the description to GDB, this involves a call to x86_linux_read_description. In x86_linux_read_description one of the first things we do is try to figure out if the process is 32-bit or 64-bit. To do this we look up the executable via the thread-id, and then attempt to read the architecture size from the executable. This isn't going to work if the executable has been deleted, or is no longer readable. And so, as we can't read the executable, we default to an i386 target and use an i386 target description. A consequence of using an i386 target description is that addresses are assumed to be 32-bits. Here's an example session that shows the problems this causes. This is run on an x86-64 machine, and the test binary (xx.x) is a standard 64-bit x86-64 binary: shell_1$ gdbserver --once localhost :54321 /tmp/xx.x shell_2$ gdb -q (gdb) set sysroot (gdb) shell chmod 000 /tmp/xx.x (gdb) target remote :54321 Remote debugging using :54321 warning: /tmp/xx.x: Permission denied. 0xf7fd3110 in ??

Notice also that the $pc value is a 32-bit value. It appears to be within one of the mappings reported by GDB, but is outside any of the mappings reported from the kernel. And this is where the problem arises. When gdbserver detaches from the inferior we pass the inferior the address from which it should resume. Due to the 32/64 bit confusion we tell the inferior to resume from the 32-bit $pc value, which is not within any valid mapping, and so, as soon as the inferior resumes, it segfaults. If we look at how GDB (not gdbserver) figures out its target description then we see an interesting difference. GDB doesn't try to read the executable. Instead GDB uses ptrace to query the thread's state, and uses this to figure out the if the thread is 32 or 64 bit. If we update gdbserver to do it the "GDB" way then the above problem is resolved, gdbserver now sees the process as 64-bit, and when we detach from the inferior we give it the correct 64-bit address, and the inferior no longer segfaults. Now, I could just update the gdbserver code, but better, I think, to share one copy of the code between GDB and gdbserver in gdb/nat/. That is what this commit does. The cores of x86_linux_read_description from gdbserver and x86_linux_nat_target::read_description from GDB are moved into a new file gdb/nat/x86-linux-tdesc.c and combined into a single function x86_linux_tdesc_for_tid which is called from each location. This new function does things mostly the GDB way, some changes are needed to allow for the sharing; we now take some pointers for where the shared code can cache the xcr0 and xsave layout values. Another thing to note about this commit is how the functions i386_linux_read_description and amd64_linux_read_description are handled. For now I've left these function as implemented separately in GDB and gdbserver. I've moved the declarations of these functions into gdb/arch/{i386,amd64}-linux-tdesc.h, but the implementations are left where they are. A later commit in this series will make these functions shared too, but doing this is not trivial, so I've left that for a separate commit. Merging the declarations as I've done here ensures that everyone implements the function to the same API, and once these functions are shared (in a later commit) we'll want a shared declaration anyway.

2024-06-14gdb: move xcr0 == 0 check into i386_linux_core_read_descriptionAndrew Burgess1-7/+8
Currently, in i386_linux_core_read_description, if GDB fails to extract an xcr0 value from the core file, then we will have a default zero value for the xcr0 variable, we still call the i386_linux_read_description function, which checks for this zero value and returns nullptr. Back in i386_linux_core_read_description we spot the nullptr return value from i386_linux_read_description and call i386_linux_read_description again, but this time passing a default value for xcr0. In the next commit I plan to rework i386_linux_read_description, and in so doing I will remove the check for xcr0 == 0, this is inline with how the amd64 code is written. However, this means that the 'xcr0 == 0' check needs to move up the stack to i386_linux_core_read_description, again, this brings the i386 code into line with the amd64 code. This is just a refactor in preparation for the next commit, there should be no user visible changes after this commit.

This is fixed in this commit. I've updated the function to follow the same pattern as amd64_linux_core_read_description, if xcr0 is 0 then we select a default xcr0 value and use that to select a tdesc.
2024-03-25gdb/gdbserver: share x86/linux tdesc cachingAndrew Burgess1-22/+8
This commit builds on the previous series of commits to share the target description caching code between GDB and gdbserver for x86/Linux targets.

Then both GDB and gdbserver will link against these shared functions. It is worth reading the description of the previous commit to see why this merging is not as simple as it seems: on the gdbserver side we actually have two users of these functions, gdbserver itself, and the in process agent (IPA). However, the previous commit streamlined the gdbserver code, and so now it is simple to move the two functions along with all their support functions from the gdbserver directory into the gdb/nat/ directory, and then GDB is fine to call these functions. One small curiosity with this patch is the function x86_linux_post_init_tdesc. On the gdbserver side the two functions amd64_linux_read_description and i386_linux_read_description have some functionality that is not present on the GDB side, that is some additional configuration that is performed as each target description is created to setup the expedited registers. To support this I've added the function x86_linux_post_init_tdesc. This function is called from the two *_linux_read_description functions, but is implemented separately for GDB and gdbserver. This does mean adding back some non-shared code when this whole series has been about sharing code, but now the only non-shared bit is the single line that is actually different between GDB and gdbserver, all the rest, which is identical, is now shared. I did need to add a new rule to the gdbserver Makefile, this is to allow the nat/x86-linux-tdesc.c file to be compiled for the IPA. Approved-By: John Baldwin <jhb@FreeBSD.org>

The I386_LINUX_XSAVE_XCR0_OFFSET #define is used as part of the target description creation, and I noticed that this constant is defined separately for GDB and gdbserver. This commit moves the definition into gdb/nat/x86-linux.h, which allows the #define to be shared. There should be no user visible changes after this commit.

2024-02-20gdb: pass frames as `const frame_info_ptr &`Simon Marchi1-5/+5
We currently pass frames to function by value, as `frame_info_ptr`. This is somewhat expensive: - the size of `frame_info_ptr` is 64 bytes, which is a bit big to pass by value - the constructors and destructor link/unlink the object in the global `frame_info_ptr::frame_list` list. This is an `intrusive_list`, so it's not so bad: it's just assigning a few points, there's no memory allocation as if it was `std::list`, but still it's useless to do that over and over. As suggested by Tom Tromey, change many function signatures to accept `const frame_info_ptr &` instead of `frame_info_ptr`. Some functions reassign their `frame_info_ptr` parameter, like: void the_func (frame_info_ptr frame) { for (; frame != nullptr; frame = get_prev_frame (frame)) { ... } } I wondered what to do about them, do I leave them as-is or change them (and need to introduce a separate local variable that can be re-assigned). I opted for the later for consistency. It might not be clear why some functions take `const frame_info_ptr &` while others take `frame_info_ptr`. Also, if a function took a `frame_info_ptr` because it did re-assign its parameter, I doubt that we would think to change it to `const frame_info_ptr &` should the implementation change such that it doesn't need to take `frame_info_ptr` anymore. It seems better to have a simple rule and apply it everywhere. Change-Id: I59d10addef687d157f82ccf4d54f5dde9a963fd0 Approved-By: Andrew Burgess <aburgess@redhat.com>

2023-02-27Catch gdb_exception_error instead of gdb_exception (in many places)Kevin Buettner1-1/+1
As described in the previous commit for this series, I became concerned that there might be instances in which a QUIT (due to either a SIGINT or SIGTERM) might not cause execution to return to the top level. In some (though very few) instances, it is okay to not propagate the exception for a Ctrl-C / SIGINT, but I don't think that it is ever okay to swallow the exception caused by a SIGTERM. Allowing that to happen would definitely be a deviation from the current behavior in which GDB exits upon receipt of a SIGTERM. I looked at all cases where an exception handler catches a gdb_exception. Handlers which did NOT need modification were those which satisifed one or more of the following conditions: 1) There is no call path to maybe_quit() in the try block. I used a static analysis tool to help make this determination. In instances where the tool didn't provide an answer of "yes, this call path can result in maybe_quit() being called", I reviewed it by hand. 2) The catch block contains a throw for conditions that it doesn't want to handle; these "not handled" conditions must include the quit exception and the new "forced quit" exception. 3) There was (also) a catch for gdb_exception_quit. Any try/catch blocks not meeting the above conditions could potentially swallow a QUIT exception. My first thought was to add catch blocks for gdb_exception_quit and then rethrow the exception. But Pedro pointed out that this can be handled without adding additional code by simply catching gdb_exception_error instead. That's what this patch series does. There are some oddball cases which needed to be handled differently, plus the extension languages, but those are handled in later patches.

2022-07-21gdb: move the type cast into gdbarch_tdepAndrew Burgess1-2/+2
I built GDB for all targets on a x86-64/GNU-Linux system, and then (accidentally) passed GDB a RISC-V binary, and asked GDB to "run" the binary on the native target. I got this error: (gdb) show architecture The target architecture is set to "auto" (currently "i386"). (gdb) file /tmp/hello.rv32.exe Reading symbols from /tmp/hello.rv32.exe... (gdb) show architecture The target architecture is set to "auto" (currently "riscv:rv32"). (gdb) run Starting program: /tmp/hello.rv32.exe ../../src/gdb/i387-tdep.c:596: internal-error: i387_supply_fxsave: Assertion `tdep->st0_regnum >= I386_ST0_REGNUM' failed. What's going on here is this; initially the architecture is i386, this is based on the default architecture, which is set based on the native target. After loading the RISC-V executable the architecture of the current inferior is updated based on the architecture of the executable. When we "run", GDB does a fork & exec, with the inferior being controlled through ptrace. GDB sees an initial stop from the inferior as soon as the inferior comes to life. In response to this stop GDB ends up calling save_stop_reason (linux-nat.c), which ends up trying to read register from the inferior, to do this we end up calling target_ops::fetch_registers, which, for the x86-64 native target, calls amd64_linux_nat_target::fetch_registers. After this I eventually end up in i387_supply_fxsave, different x86 based targets will end in different functions to fetch registers, but it doesn't really matter which function we end up in, the problem is this line, which is repeated in many places: i386_gdbarch_tdep *tdep = (i386_gdbarch_tdep *) gdbarch_tdep (arch); The problem here is that the ARCH in this line comes from the current inferior, which, as we discussed above, will be a RISC-V gdbarch, the tdep field will actually be of type riscv_gdbarch_tdep, not i386_gdbarch_tdep. After this cast we are relying on undefined behaviour, in my case I happen to trigger an assert, but this might not always be the case. The thing I tried that exposed this problem was of course, trying to start an executable of the wrong architecture on a native target. I don't think that the correct solution for this problem is to detect, at the point of cast, that the gdbarch_tdep object is of the wrong type, but, I did wonder, is there a way that we could protect ourselves from incorrectly casting the gdbarch_tdep object? I think that there is something we can do here, and this commit is the first step in that direction, though no actual check is added by this commit. This commit can be split into two parts: (1) In gdbarch.h and arch-utils.c. In these files I have modified gdbarch_tdep (the function) so that it now takes a template argument, like this: template<typename TDepType> static inline TDepType * gdbarch_tdep (struct gdbarch *gdbarch) { struct gdbarch_tdep *tdep = gdbarch_tdep_1 (gdbarch); return static_cast<TDepType *> (tdep); } After this change we are no better protected, but the cast is now done within the gdbarch_tdep function rather than at the call sites, this leads to the second, much larger change in this commit, (2) Everywhere gdbarch_tdep is called, we make changes like this: - i386_gdbarch_tdep *tdep = (i386_gdbarch_tdep *) gdbarch_tdep (arch); + i386_gdbarch_tdep *tdep = gdbarch_tdep<i386_gdbarch_tdep> (arch); There should be no functional change after this commit. In the next commit I will build on this change to add an assertion in gdbarch_tdep that checks we are casting to the correct type.

2021-12-29Use correct stream for process record outputTom Tromey1-3/+4
The process record code often emits unfiltered output. In some cases, this output ought to go to gdb_stderr (but see below). In other cases, the output is guarded by a logging variable and so ought to go to gdb_stdlog. This patch makes these changes. Note that in many cases, the output to stderr is followed by a "return -1", which is how process record indicates an error. It seems to me that calling error here would be preferable, because, in many cases, that's all the caller does when it sees a -1. However, I haven't made this change. This is part of PR gdb/7233.

2021-12-03gdb: make extract_integer take an array_viewSimon Marchi1-1/+1
I think it would make sense for extract_integer, extract_signed_integer and extract_unsigned_integer to take an array_view. This way, when we extract an integer, we can validate that we don't overflow the buffer passed by the caller (e.g. ask to extract a 4-byte integer but pass a 2-byte buffer). - Change extract_integer to take an array_view - Add overloads of extract_signed_integer and extract_unsigned_integer that take array_views. Keep the existing versions so we don't need to change all callers, but make them call the array_view versions. This shortens some places like: result = extract_unsigned_integer (value_contents (result_val).data (), TYPE_LENGTH (value_type (result_val)), byte_order); into result = extract_unsigned_integer (value_contents (result_val), byte_order); value_contents returns an array view that is of length `TYPE_LENGTH (value_type (result_val))` already, so the length is implicitly communicated through the array view.

2021-11-15gdb: fix gdbarch_tdep ODR violationSimon Marchi1-2/+2
I would like to be able to use non-trivial types in gdbarch_tdep types. This is not possible at the moment (in theory), because of the one definition rule. To allow it, rename all gdbarch_tdep types to <arch>_gdbarch_tdep, and make them inherit from a gdbarch_tdep base class. The inheritance is necessary to be able to pass pointers to all these <arch>_gdbarch_tdep objects to gdbarch_alloc, which takes a pointer to gdbarch_tdep. These objects are never deleted through a base class pointer, so I didn't include a virtual destructor. In the future, if gdbarch objects deletable, I could imagine that the gdbarch_tdep objects could become owned by the gdbarch objects, and then it would become useful to have a virtual destructor (so that the gdbarch object can delete the owned gdbarch_tdep object). But that's not necessary right now. It turns out that RISC-V already has a gdbarch_tdep that is non-default-constructible, so that provides a good motivation for this change. Most changes are fairly straightforward, mostly needing to add some casts all over the place. There is however the xtensa architecture, doing its own little weird thing to define its gdbarch_tdep. I did my best to adapt it, but I can't test those changes. Change-Id: Ic001903f91ddd106bd6ca09a79dabe8df2d69f3b

2020-12-04gdb: move displaced stepping logic to gdbarch, allow starting concurrent ↵Simon Marchi1-3/+1
displaced steps Today, GDB only allows a single displaced stepping operation to happen per inferior at a time. There is a single displaced stepping buffer per inferior, whose address is fixed (obtained with gdbarch_displaced_step_location), managed by infrun.c. In the case of the AMD ROCm target [1] (in the context of which this work has been done), it is typical to have thousands of threads (or waves, in SMT terminology) executing the same code, hitting the same breakpoint (possibly conditional) and needing to to displaced step it at the same time. The limitation of only one displaced step executing at a any given time becomes a real bottleneck. To fix this bottleneck, we want to make it possible for threads of a same inferior to execute multiple displaced steps in parallel. This patch builds the foundation for that. In essence, this patch moves the task of preparing a displaced step and cleaning up after to gdbarch functions. This allows using different schemes for allocating and managing displaced stepping buffers for different platforms. The gdbarch decides how to assign a buffer to a thread that needs to execute a displaced step. On the ROCm target, we are able to allocate one displaced stepping buffer per thread, so a thread will never have to wait to execute a displaced step. On Linux, the entry point of the executable if used as the displaced stepping buffer, since we assume that this code won't get used after startup. From what I saw (I checked with a binary generated against glibc and musl), on AMD64 we have enough space there to fit two displaced stepping buffers. A subsequent patch makes AMD64/Linux use two buffers. In addition to having multiple displaced stepping buffers, there is also the idea of sharing displaced stepping buffers between threads. Two threads doing displaced steps for the same PC could use the same buffer at the same time. Two threads stepping over the same instruction (same opcode) at two different PCs may also be able to share a displaced stepping buffer. This is an idea for future patches, but the architecture built by this patch is made to allow this. Now, the implementation details. The main part of this patch is moving the responsibility of preparing and finishing a displaced step to the gdbarch. Before this patch, preparing a displaced step is driven by the displaced_step_prepare_throw function. It does some calls to the gdbarch to do some low-level operations, but the high-level logic is there. The steps are roughly: - Ask the gdbarch for the displaced step buffer location - Save the existing bytes in the displaced step buffer - Ask the gdbarch to copy the instruction into the displaced step buffer - Set the pc of the thread to the beginning of the displaced step buffer Similarly, the "fixup" phase, executed after the instruction was successfully single-stepped, is driven by the infrun code (function displaced_step_finish). The steps are roughly: - Restore the original bytes in the displaced stepping buffer - Ask the gdbarch to fixup the instruction result (adjust the target's registers or memory to do as if the instruction had been executed in its original location) The displaced_step_inferior_state::step_thread field indicates which thread (if any) is currently using the displaced stepping buffer, so it is used by displaced_step_prepare_throw to check if the displaced stepping buffer is free to use or not. This patch defers the whole task of preparing and cleaning up after a displaced step to the gdbarch. Two new main gdbarch methods are added, with the following semantics: - gdbarch_displaced_step_prepare: Prepare for the given thread to execute a displaced step of the instruction located at its current PC. Upon return, everything should be ready for GDB to resume the thread (with either a single step or continue, as indicated by gdbarch_displaced_step_hw_singlestep) to make it displaced step the instruction. - gdbarch_displaced_step_finish: Called when the thread stopped after having started a displaced step. Verify if the instruction was executed, if so apply any fixup required to compensate for the fact that the instruction was executed at a different place than its original pc. Release any resources that were allocated for this displaced step. Upon return, everything should be ready for GDB to resume the thread in its "normal" code path. The displaced_step_prepare_throw function now pretty much just offloads to gdbarch_displaced_step_prepare and the displaced_step_finish function offloads to gdbarch_displaced_step_finish. The gdbarch_displaced_step_location method is now unnecessary, so is removed. Indeed, the core of GDB doesn't know how many displaced step buffers there are nor where they are. To keep the existing behavior for existing architectures, the logic that was previously implemented in infrun.c for preparing and finishing a displaced step is moved to displaced-stepping.c, to the displaced_step_buffer class. Architectures are modified to implement the new gdbarch methods using this class. The behavior is not expected to change. The other important change (which arises from the above) is that the core of GDB no longer prevents concurrent displaced steps. Before this patch, start_step_over walks the global step over chain and tries to initiate a step over (whether it is in-line or displaced). It follows these rules: - if an in-line step is in progress (in any inferior), don't start any other step over - if a displaced step is in progress for an inferior, don't start another displaced step for that inferior After starting a displaced step for a given inferior, it won't start another displaced step for that inferior. In the new code, start_step_over simply tries to initiate step overs for all the threads in the list. But because threads may be added back to the global list as it iterates the global list, trying to initiate step overs, start_step_over now starts by stealing the global queue into a local queue and iterates on the local queue. In the typical case, each thread will either: - have initiated a displaced step and be resumed - have been added back by the global step over queue by displaced_step_prepare_throw, because the gdbarch will have returned that there aren't enough resources (i.e. buffers) to initiate a displaced step for that thread Lastly, if start_step_over initiates an in-line step, it stops iterating, and moves back whatever remaining threads it had in its local step over queue to the global step over queue. Two other gdbarch methods are added, to handle some slightly annoying corner cases. They feel awkwardly specific to these cases, but I don't see any way around them: - gdbarch_displaced_step_copy_insn_closure_by_addr: in arm_pc_is_thumb, arm-tdep.c wants to get the closure for a given buffer address. - gdbarch_displaced_step_restore_all_in_ptid: when a process forks (at least on Linux), the address space is copied. If some displaced step buffers were in use at the time of the fork, we need to restore the original bytes in the child's address space. These two adjustments are also made in infrun.c: - prepare_for_detach: there may be multiple threads doing displaced steps when we detach, so wait until all of them are done - handle_inferior_event: when we handle a fork event for a given thread, it's possible that other threads are doing a displaced step at the same time. Make sure to restore the displaced step buffer contents in the child for them.

2020-11-02gdb, gdbserver, gdbsupport: fix leading space vs tabs issuesSimon Marchi1-10/+10
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

2020-01-13gdb: add back declarations for _initialize functionsSimon Marchi1-1/+2
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 481695ed5f6e0a8a9c9c50bfac1cdd2b3151e6c9 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

2019-09-19bfd_section_* macrosAlan Modra1-1/+1
This large patch removes the unnecessary bfd parameter from various bfd section macros and functions. The bfd is hardly ever used and if needed for the bfd_set_section_* or bfd_rename_section functions can be found via section->owner except for the com, und, abs, and ind std_section special sections. Those sections shouldn't be modified anyway. The patch also removes various bfd_get_section_<field> macros, replacing their use with bfd_section_<field>, and adds bfd_set_section_lma. I've also fixed a minor bug in gas where compressed section renaming was done directly rather than calling bfd_rename_section. This would have broken bfd_get_section_by_name and similar functions, but that hardly mattered at such a late stage in gas processing. bfd/ * bfd-in.h (bfd_get_section_name, bfd_get_section_vma), (bfd_get_section_lma, bfd_get_section_alignment), (bfd_get_section_size, bfd_get_section_flags), (bfd_get_section_userdata): Delete.

This changes a few spots that use field_fmt to use field_core_addr instead. gdb/ChangeLog 2019-07-15 Tom Tromey <tromey@adacore.com> * target.c (flash_erase_command): Use field_core_addr. * symfile.c (generic_load): Use field_core_addr. * sparc64-linux-tdep.c (sparc64_linux_handle_segmentation_fault): Use field_core_addr. * i386-linux-tdep.c (i386_linux_handle_segmentation_fault): Use field_core_addr.
2019-07-09Rename common to gdbsupportTom Tromey1-1/+1
This is the next patch in the ongoing series to move gdbsever to the top level. This patch just renames the "common" directory. The idea is to do this move in two parts: first rename the directory (this patch), then move the directory to the top. This approach makes the patches a bit more tractable. I chose the name "gdbsupport" for the directory. However, as this patch was largely written by sed, we could pick a new name without too much difficulty. Tested by the buildbot. gdb/ChangeLog 2019-07-09 Tom Tromey <tom@tromey.com> * contrib/ari/gdb_ari.sh: Change common to gdbsupport. * configure: Rebuild. * configure.ac: Change common to gdbsupport. *

2019-07-04i386/AArch64: Remove old xml testsAlan Hayward1-24/+0
Both the i386, X86_64 and AArch64 builds of gdbserver include a bunch of legacy xml files, dat files and auto generated C files, when building for unit test. These tests exists back from when feature target descriptions were added to prove that the new target descriptions were identical to the original older versions. The old files are not used for anything other than these tests. Now that this has been proven, we are not gaining anything by keeping the original files and tests. Should new functionality be added, it would break the tests, unless the functionality was backported to the xml. There is no requirement that we must match the exact xml from N releases ago. It adds obfuscation, where as the feature target descriptions were meant to simplify the code. In addition, there are a bunch of xml and dat files which are completely unused. This patch removes the selftests and the target descriptions from gdbserver. Update the unittest to allow 0 tests (note, this failed on other targets that never had any tests). gdb/ChangeLog: * aarch64-tdep.c: Remove xml self tests. * amd64-linux-tdep.c: Likewise. * amd64-tdep.c: Likewise. * i386-linux-tdep.c: Likewise. * i386-tdep.c: Likewise. gdb/gdbserver/ChangeLog: * configure.srv: Remove legacy xml. * linux-aarch64-low.c (initialize_low_arch): Remove initialize_low_tdesc call. * linux-aarch64-tdesc-selftest.c: Remove file. * linux-aarch64-tdesc.h (initialize_low_tdesc): Remove. * linux-x86-low.c (initialize_low_arch): Remove initialize_low_tdesc call. * linux-x86-tdesc-selftest.c: Remove file. * linux-x86-tdesc.h (initialize_low_tdesc): Remove. gdb/testsuite/ChangeLog: * gdb.server/unittest.exp: Allow 0 unit tests to run.
2019-04-08Rename gdb exception typesTom Tromey1-1/+1
This renames the gdb exception types. The old types were only needed due to the macros in common-exception.h that are now gone. The intermediate layer of gdb_exception_RETURN_MASK_ALL did not seem needed, so this patch removes it entirely. gdb/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * common/common-exceptions.h (gdb_exception_RETURN_MASK_ALL): Remove.

As on amd64, these registers hold the base address of the fs and gs segments, respectively. For i386 these two registers are 32 bits. gdb/ChangeLog: * amd64-fbsd-nat.c (amd64_fbsd_nat_target::read_description): Update calls to i386_target_description to add 'segments' parameter. * amd64-tdep.c (amd64_init_abi): Set tdep->fsbase_regnum. Don't add segment base registers. * arch/i386.c (i386_create_target_description): Add 'segments' parameter to enable segment base registers. * arch/i386.h (i386_create_target_description): Likewise. * features/i386/32bit-segments.xml: New file. * features/i386/32bit-segments.c: Generate. * i386-fbsd-nat.c (i386_fbsd_nat_target::read_description): Update call to i386_target_description to add 'segments' parameter. * i386-fbsd-tdep.c (i386fbsd_core_read_description): Likewise. * i386-go32-tdep.c (i386_go32_init_abi): Likewise. * i386-linux-tdep.c (i386_linux_read_description): Likewise. * i386-tdep.c (i386_validate_tdesc_p): Add segment base registers if feature is present. (i386_gdbarch_init): Pass I386_NUM_REGS to set_gdbarch_num_regs. Add 'segments' parameter to call to i386_target_description. (i386_target_description): Add 'segments' parameter to enable segment base registers. (_initialize_i386_tdep) [GDB_SELF_TEST]: Add 'segments' parameter to call to i386_target_description. * i386-tdep.h (struct gdbarch_tdep): Add 'fsbase_regnum'. (enum i386_regnum): Add I386_FSBASE_REGNUM and I386_GSBASE_REGNUM. Define I386_NUM_REGS. (i386_target_description): Add 'segments' parameter to enable segment base registers. gdb/gdbserver/ChangeLog: * linux-x86-tdesc.c (i386_linux_read_description): Update call to i386_create_target_description for 'segments' parameter. * lynx-i386-low.c (lynx_i386_arch_setup): Likewise. * nto-x86-low.c (nto_x86_arch_setup): Likewise. * win32-i386-low.c (i386_arch_setup): Likewise.
