2019-07-19Arm: Add read_description read funcs and use in GDBAlan Hayward1-3/+5
Switch the Arm target to get target descriptions via arm_read_description and aarch32_read_description, in the same style as other feature targets. Add an enum to specify the different types - this will also be of use to gdbserver in a later patch. Under the hood return the same existing pre-feature target descriptions. gdb/ChangeLog: * Makefile.in: Add new files. * aarch32-tdep.c: New file. * aarch32-tdep.h: New file. * aarch64-linux-nat.c (aarch64_linux_nat_target::read_description): Call aarch32_read_description. * arch/aarch32.c: New file. * arch/aarch32.h: New file. * arch/arm.c (arm_create_target_description) (arm_create_mprofile_target_description): New function. * arch/arm.h (arm_fp_type, arm_m_profile_type): New enum.

2018-12-08gdb/or1k: Add linux debugging supportStafford Horne1-0/+8
Up until now OpenRISC GDB only has supported bare metal debugging. This patch adds linux userspace debugging and core dump analysis support. The changes are loosely based on nios2 and riscv implementations. This was tested with linux 4.20 core dumps for executables linked against musl libc. bfd/ChangeLog: * elf32-or1k.c (or1k_grok_prstatus): New function. (or1k_grok_psinfo): Likewise. gdb/ChangeLog: * Makefile.in (ALL_TARGET_OBS): Add or1k-linux-tdep.o. * configure.tgt: Add or1k*-*-linux*. * or1k-linux-tdep.c: New file. * or1k-tdep.c (or1k_gdbarch_init): Call gdbarch_init_osabi.
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.

2018-05-22[PowerPC] Consolidate linux target description selectionPedro Franco de Carvalho1-1/+2
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.

2018-04-15Add x86-tdep.o to i386/amd64 target buildSimon Marchi1-2/+3
We get this error when doing a build with a single amd64 target (the default when doing just ./configure on x86-64 GNU/Linux): /home/simark/src/binutils-gdb/gdb/i386-tdep.c:4431: error: undefined reference to 'x86_in_indirect_branch_thunk(unsigned long, char const**, int, int)' /home/simark/src/binutils-gdb/gdb/amd64-tdep.c:3045: error: undefined reference to 'x86_in_indirect_branch_thunk(unsigned long, char const**, int, int)' The problem is that commit 1d509aa625f8 ("infrun: step through indirect branch thunks") missed adding x86-tdep.o to the list of object file included in an amd64 or i386 build.

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.

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.

2017-04-12gdb: Move DJGPP/go32 bits to their own tdep filePedro Alves1-0/+4
I posit that this makes them easier to find. The other day while working on the wchar_t patch, I had a bit of trouble finding the DJGPP/go32 tdep bits. My initial reaction was looking for a go32-specific tdep file, but there's none. Confirmed that a --host=i586-pc-msdosdjgpp GDB still builds successfully and includes the i386-go32-tdep.o object.

2016-11-23Normalize names of some source filesSimon Marchi1-40/+40
Most tdep/nat files are named: <cpu>-<os>-tdep.c <cpu>-<os>-nat.c A few files do not respect this scheme. This patch renames them so that they are consistent with the rest of the files. It builds fine with --enable-targets=all, but that doesn't test the nat files. I can only hope that my grep skill is good enough. gdb/ChangeLog: * Makefile.in (ALL_64_TARGET_OBS, ALL_TARGET_OBS, HFILES_NO_SRCDIR, ALLDEPFILES): Rename files. * alphabsd-nat.c: Rename to ... *

2016-09-21arc: New Synopsys ARC portAnton Kolesov1-0/+5
ARC is a family of licensable processors developed by Synopsys. This is an initial patch that doesn't yet support some of the features, that are already available in Synopsys' fork of GDB, namely: * longjmp support * signal frame handling * prologue analysis * Linux targets support * native Linux support ARC cores are configurable and extensible, which means from debugger perspective that some registers and debug capabilities are optional, therefore it is up to the GDB stub to determine exact list of register available on target and supply it to GDB via XML target descriptions. List of registers that is known to GDB and is required is intentionally kept small to simplify requirements to GDB stub and implementation of a GDB client. gdb/ChangeLog: * Makefile.in (ALL_TARGET_OBS): Add arc-tdep.o. (HFILES_NO_SRCDIR): Add arc-tdep.h. (ALLDEPFILES): Add arc-tdep.c. * NEWS: Mention new ARC port. * configure.tgt: Add ARC. * arc-tdep.c: New file. * arc-tdep.h: New file. * features/Makefile (XMLTOC): Add arc-v2.xml and arc-arcompact.xml. * features/arc-v2.xml: New file. * features/arc-v2.c: New file (generated). * features/arc-arcompact.xml: New file. * features/arc-arcompact.c: New file (generated). gdb/doc/ChangeLog: * gdb.texinfo (Embedded Processors): Document ARC.
