2023-08-28gdb: Support XSAVE layouts for the current host in the Linux x86 targets.John Baldwin1-1/+2
Note that this uses the CPUID instruction to determine the total size of the XSAVE register set. If there is a way to fetch the register set size using ptrace that would probably be better. Approved-By: Simon Marchi <simon.marchi@efficios.com>
2023-08-28gdb: Support XSAVE layouts for the current host in the FreeBSD x86 targets.John Baldwin1-2/+3
Use the CPUID instruction to fetch the offsets of supported state components. Approved-By: Simon Marchi <simon.marchi@efficios.com>
2023-01-01Update copyright year range in header of all files managed by GDBJoel Brobecker1-1/+1
This commit is the result of running the gdb/copyright.py script, which automated the update of the copyright year range for all source files managed by the GDB project to be updated to include year 2023.
2022-03-22Add support for hardware breakpoints/watchpoints on FreeBSD/Aarch64.John Baldwin1-1/+2
This shares aarch64-nat.c and nat/aarch64-hw-point.c with the Linux native target. Since FreeBSD writes all of the debug registers in one ptrace op, use an unordered_set<> to track the "dirty" state for threads rather than bitmasks of modified registers.
2022-03-22aarch64: Add an aarch64_nat_target mixin class.John Baldwin1-1/+1
This class includes platform-independent target methods for hardware breakpoints and watchpoints using routines from nat/aarch64-hw-point.c. stopped_data_address is not platform-independent since the FAR register holding the address for a breakpoint hit must be fetched in a platform-specific manner. However, aarch64_stopped_data_address is provided as a helper routine which performs platform-independent validation given the value of the FAR register. For tracking the per-process debug register mirror state, use an unordered_map indexed by pid as recently adopted in x86-nat.c rather than a manual linked-list.
2022-03-22nat: Split out platform-independent aarch64 debug register support.John Baldwin1-1/+2
Move non-Linux-specific support for hardware break/watchpoints from nat/aarch64-linux-hw-point.c to nat/aarch64-hw-point.c. Changes beyond a simple split of the code are: - aarch64_linux_region_ok_for_watchpoint and aarch64_linux_any_set_debug_regs_state renamed to drop linux_ as they are not platform specific. - Platforms must implement the aarch64_notify_debug_reg_change function which is invoked from the platform-independent code when a debug register changes for a given debug register state. This does not use the indirection of a 'low' structure as is done for x86. - The handling for kernel_supports_any_contiguous_range is not pristine. For non-Linux it is simply defined to true. Some uses of this could perhaps be implemented as new 'low' routines for the various places that check it instead? - Pass down ptid into aarch64_handle_breakpoint and aarch64_handle_watchpoint rather than using current_lwp_ptid which is only defined on Linux. In addition, pass the ptid on to aarch64_notify_debug_reg_change instead of the unused state argument.
2022-03-22x86-fbsd-nat: Copy debug register state on fork.John Baldwin1-2/+2
Use the FreeBSD native target low_new_fork hook to copy the per-process debug state from the parent to the child on fork.

2022-01-28FreeBSD x86 nat: Use register maps for GP register sets.John Baldwin1-2/+2
Rather than using the x86-specific register offset tables, use register maps to describe the layout of the general purpose registers fetched via PT_GETREGS. The sole user-visible difference is that FreeBSD/amd64 will now report additional segment registers ($ds, $es, $fs, and $gs) for both 32-bit and 64-bit processes. As part of these changes, the FreeBSD x86 native targets no longer use amd64-bsd-nat.c or i386-bsd-nat.c. Remove FreeBSD-specific register handling (for $fs_base, $gs_base, and XSAVE state) from these files. Similarly, remove the global x86bsd_xsave_len from x86-bsd-nat.c. The FreeBSD x86 native targets use a static xsave_len instead. While here, rework the probing of PT_GETXMMREGS on FreeBSD/i386. Probe the ptrace op once in the target read_description method and cache the result for the future similar to the way the status of XSAVE support is probed in the read_description method. In addition, return the proper xcr0 mask (X87-only) for old kernels or systems without either XSAVE or XMM support.

2021-11-18gdb: rename rs6000-nat.c to rs6000-aix-nat.cSimon Marchi1-1/+1
This file seems to be AIX-specific, according to its contents and configure.nat. Rename it to rs6000-aix-nat.c, to make that clear (and to follow the convention). Change-Id: Ib418dddc6b79b2e28f64431121742b5e87f5f4f5
2021-10-29gdb: or1k: add native linux supportStafford Horne1-0/+4
This patch adds support for running gdb natively on OpenRISC linux. Debugging support is provided via the linux PTRACE interface which is mostly handled by GDB genric code. This patch provides the logic of how to read and write the ptrace registers between linux and GDB. Single stepping is privided in a separate patch.
2021-07-29Don't compile x86 debug register support on OpenBSD.John Baldwin1-3/+2
Simon Marchi tried gdb on OpenBSD, and it immediately segfaults when running a program. Simon tracked down the problem to x86_dr_low.get_status being nullptr at this point: (lldb) print x86_dr_low.get_status (unsigned long (*)()) $0 = 0x0000000000000000 (lldb) bt * thread #1, stop reason = step over * frame #0: 0x0000033b64b764aa gdb`x86_dr_stopped_data_address(state=0x0000033d7162a310, addr_p=0x00007f7ffffc5688) at x86-dregs.c:645:12 frame #1: 0x0000033b64b766de gdb`x86_dr_stopped_by_watchpoint(state=0x0000033d7162a310) at x86-dregs.c:687:10 frame #2: 0x0000033b64ea5f72 gdb`x86_stopped_by_watchpoint() at x86-nat.c:206:10 frame #3: 0x0000033b64637fbb gdb`x86_nat_target<obsd_nat_target>::stopped_by_watchpoint(this=0x0000033b65252820) at x86-nat.h:100:12 frame #4: 0x0000033b64d3ff11 gdb`target_stopped_by_watchpoint() at target.c:468:46 frame #5: 0x0000033b6469b001 gdb`watchpoints_triggered(ws=0x00007f7ffffc61c8) at breakpoint.c:4790:32 frame #6: 0x0000033b64a8bb8b gdb`handle_signal_stop(ecs=0x00007f7ffffc61a0) at infrun.c:6072:29 frame #7: 0x0000033b64a7e3a7 gdb`handle_inferior_event(ecs=0x00007f7ffffc61a0) at infrun.c:5694:7 frame #8: 0x0000033b64a7c1a0 gdb`fetch_inferior_event() at infrun.c:4090:5 frame #9: 0x0000033b64a51921 gdb`inferior_event_handler(event_type=INF_REG_EVENT) at inf-loop.c:41:7 frame #10: 0x0000033b64a827c9 gdb`infrun_async_inferior_event_handler(data=0x0000000000000000) at infrun.c:9384:3 frame #11: 0x0000033b6465bd4f gdb`check_async_event_handlers() at async-event.c:335:4 frame #12: 0x0000033b65070917 gdb`gdb_do_one_event() at event-loop.cc:216:10 frame #13: 0x0000033b64af0db1 gdb`start_event_loop() at main.c:421:13 frame #14: 0x0000033b64aefe9a gdb`captured_command_loop() at main.c:481:3 frame #15: 0x0000033b64aed5c2 gdb`captured_main(data=0x00007f7ffffc6470) at main.c:1353:4 frame #16: 0x0000033b64aed4f2 gdb`gdb_main(args=0x00007f7ffffc6470) at main.c:1368:7 frame #17: 0x0000033b6459d787 gdb`main(argc=5, argv=0x00007f7ffffc6518) at gdb.c:32:10 frame #18: 0x0000033b6459d521 gdb`___start + 321 On BSDs, get_status is set in _initialize_x86_bsd_nat, but only if HAVE_PT_GETDBREGS is defined. PT_GETDBREGS doesn't exist on OpenBSD, so get_status (and the other fields of x86_dr_low) are left as nullptr. OpenBSD doesn't support getting or setting the x86 debug registers, so fix by omitting debug register support entirely on OpenBSD: - Change x86bsd_nat_target to only inherit from x86_nat_target if PT_GETDBREGS is supported. - Don't include x86-nat.o and nat/x86-dregs.o for OpenBSD/amd64. They were already omitted for OpenBSD/i386.

2019-09-20Remove Cell Broadband Engine debugging supportUlrich Weigand1-17/+0
This patch implements removal of Cell/B.E. support, including - Support for the spu-*-* target - Support for native stand-alone SPU debugging - Support for integrated debugging of combined PPU/SPU applications - Remote debugging (gdbserver) support for all the above. The patch also removes the TARGET_OBJECT_SPU target object type, as this is available only on Cell/B.E. targets, including - Native Linux support - Core file support (including core file generation) - Remote target support, including removal of the qXfer:spu:read and qXfer:spu:write remote protocal packets and associated support in gdbserver. gdb/ChangeLog 2019-09-20 Ulrich Weigand <uweigand@de.ibm.com> * NEWS: Mention that Cell/B.E. debugging support was removed. * MAINTAINERS: Remove spu target. * config/djgpp/fnchange.lst: Remove entries for removed files. * Makefile.in (ALL_TARGET_OBS): Remove solib-spu.o, spu-multiarch.o, and spu-tdep.o.

2019-01-01Update copyright year range in all GDB files.Joel Brobecker1-1/+1
This commit applies all changes made after running the gdb/copyright.py script. Note that one file was flagged by the script, due to an invalid copyright header (gdb/unittests/basic_string_view/element_access/char/empty.cc). As the file was copied from GCC's libstdc++-v3 testsuite, this commit leaves this file untouched for the time being; a patch to fix the header was sent to gcc-patches first. gdb/ChangeLog: Update copyright year range in all GDB files.
2018-12-27Build gdb "nat" files in subdirectoryTom Tromey1-33/+40
This moves the various "nat" object files into the nat/ subdirectory. This allows for the removal of a pattern rule from the gdb Makefile, which is a small cleanup. I made the configure.nat change in a (semi-) automated way, hopefully meaning that it is more likely to be correct than had I done it by hand. Eventually I would like for the various configure scripts to only mention source files, and let the Makefile compute the object file names. gdb/ChangeLog 2018-12-27 Tom Tromey <tom@tromey.com> * configure.nat (NATDEPFILES): Use nat/ prefix. * Makefile.in (CONFIG_SRC_SUBDIR): Add nat.

2018-09-20Fold i386-v4-nat.c into i386-sol2-nat.cRainer Orth1-1/+1
I've been carrying around the following patch for some time. I noticed that both i386-sol2-nat.c and i386-v4-nat.c are Solaris-only now and it seems confusing to carry both around. So this patch merges i386-v4-nat.c into i386-sol2-nat.c, simplifying it in a couple of places, like removing checks for macros that are always defined. Tested on 64-bit Solaris 11.5/x86 (amd64-pc-solaris2.11) and 32-bit Solaris 11.3/x86 (i386-pc-solaris2.11) half a year ago. * i386-v4-nat.c (regmap, supply_gregset, fill_gregset) (supply_fpregset, fill_fpregset): Move ... * i386-sol2-nat.c [PR_MODEL_NATIVE != PR_MODEL_LP64]: ... here.

2018-05-22[PowerPC] Consolidate wordsize getter between native and gdbserverPedro Franco de Carvalho1-1/+1
This patch moves the native target wordsize getter for ppc linux to nat/ so that it can be used to simplify ppc_arch_setup in gdbserver. The ptrace call used to get MSR for this is ultimately the same as before, but it is no longer necessary to create a temporary regcache to call fetch_inferior_registers. gdb/ChangeLog: 2018-05-22 Pedro Franco de Carvalho <pedromfc@linux.vnet.ibm.com> * configure.nat <linux powerpc>: Add ppc-linux.o to NATDEPFILES. * ppc-linux-nat.c (ppc_linux_target_wordsize): Move to nat/ppc-linux.c.

2018-05-03Make inf_ptrace_trad Linux-only, move to separate filePedro Alves1-3/+3
There are only two inf_ptrace_trad_target users, MIPS GNU/Linux and Alpha GNU/Linux. They both call it via linux_trad_target. Move this code out of inf-ptrace.c to a GNU/Linux-specific new file. Making this code be GNU/Linux-specific simplifies C++ification of target_ops, because we can make the trad target inherit linux_nat instead of inheriting inf_ptrace. That'll be visible in a later patch. Note this makes linux_target_install_ops an extern function, but that is temporary -- the function will disappear once target_ops is made a C++ class with virtual methods, later in the series. Also, I did not rename the functions in the new file for a similar reason. They'll be renamed again anyway in a couple of patches. gdb/ChangeLog: 2018-05-02 Pedro Alves <palves@redhat.com> * alpha-linux-nat.c: Include "linux-nat-trad.h" instead of "linux-nat.h". * configure.nat (alpha-linux, linux-mips): Add linux-nat-trad.o. * inf-ptrace.c (inf_ptrace_register_u_offset) (inf_ptrace_fetch_register, inf_ptrace_fetch_registers) (inf_ptrace_store_register, inf_ptrace_store_registers) (inf_ptrace_trad_target): Move to ... * linux-nat-trad.c: ... this new file. * linux-nat-trad.h: New file. * linux-nat.c (linux_target_install_ops): Make extern.

2017-09-26Remove support for Solaris < 10 (PR gdb/22185)Rainer Orth1-26/+12
Given that GCC has obsoleted/removed support for Solaris 9 in GCC 4.9/5 in 2013: https://gcc.gnu.org/gcc-4.9/changes.html https://gcc.gnu.org/ml/gcc-patches/2013-05/msg00728.html and the last gdb version that can be compiled with gcc 4.9 is 7.12.1 only when configured with --disable-build-with-cxx, it's time to obsolete/remove support for Solaris < 10. This patch does this, simplifying configure.nat along the way (only a single sol2 configuration with variants for i386 and sparc). Some configure checks for older Solaris versions can go, too, and the check for libthread_db.so.1 removed: * Since Solaris 10, dlopen has moved to libc and libdl.so is just a filter on ld.so.1, so no need to check. * $RDYNAMIC is already handled above (and is a no-op with Solaris ld anyway). Both proc-service.c and sol-thread.c lose support for (Solaris-only) PROC_SERVICE_IS_OLD. The attached revised patch has been tested on sparcv9-sun-solaris2.10, sparcv9-sun-solaris2.11.4, amd64-pc-solaris2.10, amd64-pc-solaris2.11.4, and x86_64-pc-linux-gnu.

2017-06-07Share fork_inferior et al with gdbserverSergio Durigan Junior1-4/+4
This is the most important (and the biggest, sorry) patch of the series. It moves fork_inferior from gdb/fork-child.c to nat/fork-inferior.c and makes all the necessary adjustments to both GDB and gdbserver to make sure everything works OK. There is no "most important change" with this patch; all changes are made in a progressive way, making sure that gdbserver had the necessary features while not breaking GDB at the same time. I decided to go ahead and implement a partial support for starting the inferior with a shell on gdbserver, although the full feature comes in the next patch. The user won't have the option to disable the startup-with-shell, and also won't be able to change which shell gdbserver will use (other than setting the $SHELL environment variable, that is). Everything is working as expected, and no regressions were present during the tests. gdb/ChangeLog: 2017-06-07 Sergio Durigan Junior <sergiodj@redhat.com> Pedro Alves <palves@redhat.com> * Makefile.in (HFILES_NO_SRCDIR): Add "common/common-inferior.h" and "nat/fork-inferior.h". * common/common-inferior.h: New file, with contents from "gdb/inferior.h". * commom/common-utils.c: Include "common-utils.h".

2017-05-06Rearrange gdb/configure.nat to make it simpler and less redundantSergio Durigan Junior1-528/+410
The previous commit introduced gdb/configure.nat, but it was just a copy-and-past (with the necessary adjustments) from the files under gdb/config/. We can do better than that. Instead of using one big 'case' statement that matches the ${gdb_host_cpu} and then match each ${gdb_host}, it is possible to remove a lof of redundancy by matching the most common ${gdb_host}'s first, setting the common variables for each, and then proceed to matching specific ${gdb_host}'s and ${gdb_host_cpu}'s. In other words, reverse the order of the 'case's and take advantage of the fact that a lot of parameters are the same for each host. This commit was tested on x86_64 without regressions. gdb/ChangeLog: 2017-05-06 Sergio Durigan Junior <sergiodj@redhat.com> * configure.nat: Rearrange 'case' statements to match host before cpu.
2017-05-06Introduce "gdb/configure.nat" (and delete "gdb/config/*/*.mh" files)Sergio Durigan Junior1-0/+602
Due to my ongoing work to make it possible for gdbserver to start the inferior using the shell, I had to share the fork_inferior function under the "nat/" directory. In order to do that, I created a new file and put the function there; however, this meant that I now had to update some of the *.mh files (under "gdb/config") and add the new file as a dependency to be built natively. Bleh... After talking a bit to Pedro about this, the idea came up to write a new "gdb/configure.nat" file, a la "gdb/configure.tgt", which would concentrate all of the native settings for each host/system. I decided to tackle this issue. The patch is simple. All of the previous Makefile variables that were being declared inside the *.mh files are now inside "gdb/Makefile.in", and "gdb/configure" is responsible for AC_SUBST'ing them. The definitions of these variables were put inside "gdb/configure.nat", so now they're shell variables. For excerpts of Makefile code, one must create a file under "gdb/config/${gdb_cpu_host}" and reference it on the "nat_extra_makefile_frag" variable. It should now be easier to update the native dependencies of hosts in this single file. This has been tested on x86_64 without regressions. gdb/ChangeLog: 2017-05-06 Sergio Durigan Junior <sergiodj@redhat.com> * Makefile.in: Remove "@host_makefile_frag@".
