2020-06-25Don't include *sol2-tdep.o on Linux/sparc*Rainer Orth1-4/+4
Linux/sparc* currently links Solaris-specific files (sparc-sol2-tdep.o, sparc64-sol2-tdep.o, sol2-tdep.o) for no apparent reason. It has no business doing so, and none of the functions/variables defined there are used explicitly. If support for the Solaris OSABI were desired, this should be done using --enable-targets instead. Since neither sparc{32,64}_sol2_init_abi currently declared in common headers (sparc*-tdep.h) are used outside their source files, they are made static and the declarations removed. Tested on sparcv9-sun-solaris2.11 and sparc64-unknown-linux-gnu. * configure.tgt <sparc-*-linux*> (gdb_target_obs): Remove sparc-sol2-tdep.o, sol2-tdep.o, sparc64-sol2-tdep.o. <sparc64-*-linux*> (gdb_target_obs): Remove sparc64-sol2-tdep.o, sol2-tdep.o, sparc-sol2-tdep.o. * sparc-sol2-tdep.c (sparc32_sol2_init_abi): Make static. * sparc-tdep.h (sparc32_sol2_init_abi): Remove. * sparc64-sol2-tdep.c (sparc64_sol2_init_abi): Make static. * sparc64-tdep.h (sparc64_sol2_init_abi): Remove.
2020-03-16arc: Migrate to new target featuresAnton Kolesov1-1/+1
This patch replaces usage of target descriptions in ARC, where the whole description is fixed in XML, with new target descriptions where XML describes individual features, and GDB assembles those features into actual target description. v2: Removed arc.c from ALLDEPFILES in gdb/Makefile.in. Removed vim modeline from arc-tdep.c to have it in a separate patch. Removed braces from one line "if/else". Undid the type change for "jb_pc" (kept it as "int"). Joined the unnecessary line breaks into one line. No more moving around arm targets in gdb/features/Makefile. Changed pattern checking for ARC features from "arc/{aux,core}" to "arc/". v3: Added include gaurds to arc.h. Added arc_read_description to _create_ target descriptions less. v4: Got rid of ARC_SYS_TYPE_NONE. Renamed ARC_SYS_TYPE_INVALID to ARC_SYS_TYPE_NUM. Fixed a few indentations/curly braces. Converted arc_sys_type_to_str from a macro to an inline function. gdb/ChangeLog: 2020-03-16 Anton Kolesov <anton.kolesov@synopsys.com> Shahab Vahedi <shahab@synopsys.com> * Makefile.in: Add arch/arc.o * configure.tgt: Likewise. * arc-tdep.c (arc_tdesc_init): Use arc_read_description.

2020-03-16gdb: rename i386-cygwin-tdep.c to i386-windows-tdep.cSimon Marchi1-3/+3
Since this file contains things that apply not only to Cygwin binaries, but also to non-Cygwin Windows binaries, I think it would make more sense for it to be called i386-windows-tdep.c. It is analogous to amd64-windows-tdep.c, which we already have. gdb/ChangeLog: * i386-cygwin-tdep.c: Rename to... * i386-windows-tdep.c: ... this. * Makefile.in (ALL_TARGET_OBS): Rename i386-cygwin-tdep.c to i386-windows-tdep.c. * configure.tgt: Likewise.
2020-03-16gdb: add Windows OS ABISimon Marchi1-2/+2
GDB currently uses the "Cygwin" OS ABI (GDB_OSABI_CYGWIN) for everything related to Windows. If you build a GDB for a MinGW or Cygwin target, it will have "Cygwin" as the default OS ABI in both cases (see configure.tgt). If you load either a MinGW or Cygwin binary, the "Cygwin" OS ABI will be selected in both cases. This is misleading, because Cygwin binaries are a subset of the binaries running on Windows. When building something with MinGW, the resulting binary has nothing to do with Cygwin. Cygwin binaries are only special in that they are Windows binaries that link to the cygwin1.dll library (if my understanding is correct). Looking at i386-cygwin-tdep.c, we can see that GDB does nothing different when dealing with Cygwin binaries versus non-Cygwin Windows binaries. However, there is at least one known bug which would require us to make a distinction between the two OS ABIs, and that is the size of the built-in "long" type on x86-64. On native Windows, this is 4, whereas on Cygwin it's 8. So, this patch adds a new OS ABI, "Windows", and makes GDB use it for i386 and x86-64 PE executables, instead of the "Cygwin" OS ABI. A subsequent patch will improve the OS ABI detection so that GDB differentiates the non-Cygwin Windows binaries from the Cygwin Windows binaries, and applies the "Cygwin" OS ABI for the latter. The default OS ABI remains "Cygwin" for the GDBs built with a Cygwin target. I've decided to split the i386_cygwin_osabi_sniffer function in two, I think it's cleaner to have a separate sniffer for Windows binaries and Cygwin cores, each checking one specific thing. gdb/ChangeLog: * osabi.h (enum gdb_osabi): Add GDB_OSABI_WINDOWS. * osabi.c (gdb_osabi_names): Add "Windows". * i386-cygwin-tdep.c (i386_cygwin_osabi_sniffer): Return GDB_OSABI_WINDOWS when the binary's target is "pei-i386". (i386_cygwin_core_osabi_sniffer): New function, extracted from i386_cygwin_osabi_sniffer. (_initialize_i386_cygwin_tdep): Register OS ABI GDB_OSABI_WINDOWS for i386. * amd64-windows-tdep.c (amd64_windows_osabi_sniffer): Return GDB_OSABI_WINDOWS when the binary's target is "pei-x86-64". (_initialize_amd64_windows_tdep): Register OS ABI GDB_OSABI_WINDOWS for x86-64. * configure.tgt: Use GDB_OSABI_WINDOWS as the default OS ABI when the target matches '*-*-mingw*'.
2020-02-07Move gdbserver to top levelTom Tromey1-24/+0
This patch moves gdbserver to the top level. This patch is as close to a pure move as possible -- gdbserver still builds its own variant of gnulib and gdbsupport. Changing this will be done in a separate patch. [v2] Note that, per Simon's review comment, this patch changes the tree so that gdbserver is not built for or1k or score. This makes sense, because there is apparently not actually a gdbserver port here. [v3] This version of the patch also splits out some configury into a new file, gdbserver/configure.host, so that the top-level configure script can simply rely on it in order to decide whether gdbserver should be built. [v4] This version adds documentation and removes some unnecessary top-level dependencies. [v5] Update docs to mention "make all-gdbserver" and change how top-level configure decides whether to build gdbserver, switching to a single, shared script. Tested by the buildbot. ChangeLog 2020-02-07 Tom Tromey <tom@tromey.com> Pedro Alves <palves@redhat.com> * src-release.sh (GDB_SUPPORT_DIRS): Add gdbserver. * gdbserver: New directory, moved from gdb/gdbserver. * configure.ac (host_tools): Add gdbserver. Only build gdbserver on certain systems. * Makefile.in, configure: Rebuild. * Makefile.def (host_modules, dependencies): Add gdbserver. * MAINTAINERS: Add gdbserver. gdb/ChangeLog 2020-02-07 Tom Tromey <tom@tromey.com> * README: Update gdbserver documentation. * gdbserver: Move to top level. * configure.tgt (build_gdbserver): Remove. * configure.ac: Remove --enable-gdbserver. * configure: Rebuild. * Makefile.in (distclean): Don't mention gdbserver.

2019-11-04Obsolete Solaris 10 supportRainer Orth1-0/+1
Here's the patch corresponding to the Solaris 10 obsoletion announcement https://sourceware.org/ml/gdb/2019-10/msg00008.html Right now it doesn't remove any code, but obviates the need to test on that ancient platform. Besides, some of the patches I have in my queue would require different solutions for Solaris 10 and 11. There are a few comment-only references that I've kept since they are still correct as is, even when GDB doesn't support Solaris 10 any longer. The only code fragment I've left in is support for /proc/<pid/path/a.out in procfs.c (procfs_target::pid_to_exec_file): while current Solaris 11 updates provide /proc/<pid>/execname, that wasn't present in Solaris 11.0 and still isn't in current Illumos and I didn't want to make live harder for them. Tested on i386-pc-solaris2.10 (obsolete configuration rejected) and x86_64-pc-linux-gnu x sparc64-solaris2.10 (likewise) resp. x86_64-pc-linux-gnu x sparcv9-solaris2.11 (still builds; I'm using the sparcv9 form for 64-bit SPARC customary on Solaris in the MAINTAINERS file now). * NEWS (Changes since GDB 8.3): Document Solaris 10 removal. * configure.host: Mark *-*-solaris2.10* obsolete. * configure.tgt: Mark Solaris < 11 obsolete. * MAINTAINERS (Target Instruction Set Architectures) <sparc>: Update target triplet.

Up until now OpenRISC GDB only has supported bare metal debugging. This patch adds linux userspace debugging and core dump analysis support.

2018-11-21gdb/riscv: Add target description supportAndrew Burgess1-3/+6
This commit adds target description support for riscv. I've used the split feature approach for specifying the architectural features, and the CSR feature is auto-generated from the riscv-opc.h header file. If the target doesn't provide a suitable target description then GDB will build one by looking at the bfd headers. This commit does not implement target description creation for the Linux or FreeBSD native targets, both of these will need to add read_description methods into their respective target classes, which probe the target features, and then call riscv_create_target_description to build a suitable target description. Until this is done Linux and FreeBSD will get the same default target description based on the bfd that bare-metal targets get. I've only added feature descriptions for 32 and 64 bit registers, 128 bit registers (for RISC-V) are not supported in the reset of GDB yet. This commit removes the special reading of the MISA register in order to establish the target features, this was only used for figuring out the f-register size, and even that wasn't done consistently. We now rely on the target to tell us what size of registers it has (or look in the BFD as a last resort). The result of this is that we should now support RV64 targets with 32-bit float, though I have not extensively tested this combination yet. * Makefile.in (ALL_TARGET_OBS): Add arch/riscv.o.

2018-11-01arm-pikeos: software single stepJerome Guitton1-0/+1
On ARM, PikeOS does not support hardware single step, causing various semi-random errors when trying to next/step over some user code. So this patch changes this target to use software-single-step instead. The challenge is that, up to now, the PikeOS target was in all respects identical to a baremetal target as far as GDB was concerned, meaning we were using the baremetal osabi for this target too. This is no longer possible, and we need to introduce a new OSABI variant. Unfortunately, there isn't anything in the object file that would allow us to differentiate between the two platforms. So we have to rely on a heuristic instead, where we look for some known symbols that are required in a PikeOS application (these symbols are expected to be defined by the default linker script, and correspond to routines used to allocate the application stack). For the long run, the hope is that the stub implementation provided by PikeOS is enhanced so that it includes vContSupported+ to the $qSupported query, and then that the reply to the "vCont?" query only return support for "continue" operations (thus exclusing "step" operations). We could then use that information to reliably determine at connection time that the target does not support single-stepping and therefore automatically turn software single-stepping automatically based on it. gdb/ChangeLog: * defs.h (enum gdb_osabi): Add GDB_OSABI_PIKEOS. * osabi.c (gdb_osabi_names): Add name for GDB_OSABI_PIKEOS. * arm-pikeos-tdep.c: New file. * configure.tgt: Add arm-pikeos-tdep.o to the case of ARM embedded system. * Makefile.in (ALL_TARGET_OBS): Add arm-pikeos-tdep.o. Tested on arm-pikeos and arm-elf using AdaCore's testsuite. We also evaluated it on armhf-linux as a cross platform.

Share target description declarations and selection among ppc linux native targets, core files, gdbserver and IPA. To avoid complicated define guards, gdbserver and IPA now have declarations for all descriptions, including 64-bit generated descriptions when compiled in 32-bit mode. These have always been linked into the gdbserver and IPA binaries. Because they might be uninitialized, the selection function checks that the selected description is initialized. gdb/ChangeLog: 2018-05-22 Pedro Franco de Carvalho <pedromfc@linux.vnet.ibm.com> * arch/ppc-linux-common.c: New file. * arch/ppc-linux-common.h: New file. * arch/ppc-linux-tdesc.h: New file. * configure.tgt (powerpc*-*-linux*): Add arch/ppc-linux-common.o. * Makefile.in (ALL_TARGET_OBS): Add arch/ppc-linux-common.o.

2018-03-06gdb: Initial baremetal riscv supportAndrew Burgess1-0/+5
This commit introduces basic support for baremetal RiscV as a GDB target. This target is currently only tested against the RiscV software simulator, which is not included as part of this commit. The target has been tested against the following RiscV variants: rv32im, rv32imc, rv32imf, rv32imfc, rv64im, rv64imc, rv64imfd, rv64imfdc. Across these variants we pass on average 34858 tests, and fail 272 tests, which is ~0.8%. The RiscV has a feature of its ABI where structures with a single floating point field, a single complex float field, or one float and one integer field are treated differently for argument passing. The new test gdb.base/infcall-nested-structs.exp is added to cover this feature. As passing these structures should work on all targets then I've made the test as a generic one, even though, for most targets, there's probably nothing special about any of these cases. gdb/ChangeLog: * Makefile.in (ALL_TARGET_OBS): Add riscv-tdep.o (HFILES_NO_SRCDIR): Add riscv-tdep.h.

2018-01-23s390: Split up s390-linux-tdep.c into two filesPhilipp Rudo1-2/+2
Currently all target dependent code for s390 is in one file, s390-linux-tdep.c. This includes code general for the architecture as well as code specific for uses in GNU/Linux (user space). Up until now this was OK as GNU/Linux was the only supported OS. In preparation to support the new Linux kernel 'OS' split up the existing s390 code into a general s390-tdep and a GNU/Linux-specific s390-linux-tdep. Note: The record-replay feature will be moved in a separate patch. This is simply due to the fact that the combined patch would be too large for the mailing list. This requires setting the process_record hook during OSABI init to keep the code bisectable. The patch moving record-replay cleans up this hack. gdb/ChangeLog: * s390-linux-nat.c (s390-tdep.h): New include. * Makefile.in (ALL_TARGET_OBS): Add s390-tdep.o. (HFILES_NO_SRCDIR): Add s390-tdep.h.

2017-12-12gdb: Add OpenRISC or1k and or1knd target supportFranck Jullien1-0/+6
This patch prepares the current GDB port of the OpenRISC processor from https://github.com/openrisc/binutils-gdb for upstream merging. Testing has been done with a cgen sim provided in a separate patch. This has been tested with 2 toolchains. GCC [1] 5.4.0 from the OpenRISC project with Newlib [2] and GCC 5.4.0 with Musl [3] 1.1.4. It supports or1knd (no delay slot target). The default target is or1k (with delay slot). You can change the target arch with: (gdb) set architecture or1knd The target architecture is assumed to be or1knd [1] https://github.com/openrisc/or1k-gcc [2] https://github.com/openrisc/newlib [3] https://github.com/openrisc/musl-cross gdb/doc/ChangeLog: 2017-12-12 Stafford Horne <shorne@gmail.com> Stefan Wallentowitz <stefan@wallentowitz.de> Franck Jullien <franck.jullien@gmail.com> Jeremy Bennett <jeremy.bennett@embecosm.com> * gdb.texinfo: Add OpenRISC documentation. gdb/ChangeLog: 2017-12-12 Stafford Horne <shorne@gmail.com> Stefan Wallentowitz <stefan@wallentowitz.de> Stefan Kristiansson <stefan.kristiansson@saunalahti.fi> Franck Jullien <franck.jullien@gmail.com> Jeremy Bennett <jeremy.bennett@embecosm.com> * configure.tgt: Add targets for or1k and or1knd. * or1k-tdep.c: New file. * or1k-tdep.h: New file. * features/Makefile: Add or1k.xml to build. * features/or1k.xml: New file. * features/or1k-core.xml: New file. * features/or1k.c: Generated.
2017-12-08S390: Add symfile-memAndreas Arnez1-1/+1
For some reason symfile-mem.o is not included in the configuration for "s390*-*-linux*". It was added to the configuration of most GNU/Linux targets with a patch from Andrew Cagney: "Add symfile-mem to all linux targets" -- https://sourceware.org/ml/gdb-patches/2005-02/msg00053.html But the s390 target was overlooked at that time. Thus the command "add-symbol-file-from-memory" is missing and VDSO symbols are not loaded. This is fixed. gdb/ChangeLog: * configure.tgt (s390*-*-linux*): Add symfile-mem.o.

2017-10-11Add FreeBSD/arm architecture.John Baldwin1-0/+4
Support for collecting and supplying general purpose and floating point registers is provided along with signal frame unwinding. While FreeBSD/arm kernels do populate NT_FPREGSET notes, they are always zero-filled, so this implementation ignores them. Recent FreeBSD/arm kernels generate NT_ARM_VFP notes which are used to supply floating-point registers. As with Linux, the AT_HWCAP feature flags are used to determine the correct target description. gdb/ChangeLog: * Makefile.in (ALL_TARGET_OBS): Add arm-fbsd-tdep.o.

2017-10-06Share code updating gdb_target_obsYao Qi1-109/+129
Nowadays, there are much duplications in configure.tgt to update gdb_target_obs, some cpu specific object files are added to gdb_target_obs to some different target triplets of the same cpu. The same problem exists for os specific object files too. It is fragile to update them, and build with all targets enabled doesn't find the problem. This patch splits the gdb_target_obs update to three steps, cpu steps, os steps, and the rest.

2017-10-06[RFC] Replicate src dir in build dirYao Qi1-12/+12
Nowadays, GDB build tree is almost flat, but source tree isn't. We have arch/ nat/ target/ common/ cli/ mi/ tui/ python/ guile/ directories. We need to some rules in Makefile for source files in different source directories, like, # Rules for compiling .c files in the various source subdirectories. %.o: ${srcdir}/arch/%.c $(COMPILE) $< $(POSTCOMPILE) %.o: ${srcdir}/nat/%.c $(COMPILE) $< $(POSTCOMPILE) so we should take care of some special case that files' base name is the same, like, # Specify an explicit rule for gdb/common/agent.c, to avoid a clash with the # object file generate by gdb/agent.c. common-agent.o: $(srcdir)/common/agent.c $(COMPILE) $(srcdir)/common/agent.c $(POSTCOMPILE) As we add more and more files in different directories, it becomes tricky to name files, because we need take this into account. This patch takes the first step toward "Replicate src dir in build dir", that is, we create arch/ directory in buildtree, and put amd64.o there as an example. Dependency tracking is updated for files with directory name. Currently, when we build amd64.o, "-c -o amd64.o -MT amd64.o -MMD -MP -MF .deps/amd64.Tpo" with this patch applied, it becomes, "-c -o arch/amd64.o -MT arch/amd64.o -MMD -MP -MF arch/.deps/amd64.o.Tpo" "make clean" removes the object files, and "make distclean" removes .deps additionally. configure file create .deps directory in each of CONFIG_SRC_SUBDIR, and pass it to Makefile.in, so that "make clean" and "make distclean" can remove stuffs there. If people agree with this change, I'll add more directories to CONFIG_SRC_SUBDIR. gdb: 2017-10-06 Yao Qi <yao.qi@linaro.org> * Makefile.in (CONFIG_SRC_SUBDIR): New. (ALL_64_TARGET_OBS): Replace amd64.o with arch/amd64.o. (clean): Remove object files and dependency files. (distclean): Remove the directory. * configure.ac: Invoke AC_CONFIG_COMMANDS. * configure: Re-generated. * configure.tgt: Replace amd64.o with arch/amd64.o.
2017-09-26Remove support for Solaris < 10 (PR gdb/22185)Rainer Orth1-12/+1
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. I've also started an i386-pc-solaris2.9 build to check that it really stops as expected. PR gdb/22185 * configure.host <*-*-solaris2.[01], *-*-solaris2.[2-9]*>: Mark as obsolete.
