2016-10-06Make "end" field in feature specs required again.Doug Evans17-129/+132
Newer gdbservers may be talking to older gdbs, and older gdbs will flag a missing "end" as an error. So just make "end" required again, and for compatibility change the default field type to "bool". gdb/ChangeLog: 2016-10-06 Doug Evans <dje@google.com> * features/aarch64-core.xml (cpsr_flags): Elide "type" and specify "end" in all fields. * features/aarch64.c: Regenerate. * features/i386/32bit-mpx.xml (_bndcfgu): Specify type of "preserved" and "enabled" fields.

2016-10-05Generate s390 target description c filesYao Qi1-0/+4
If I delete all target description c files under features/ directory, and run make GDB=/scratch/yao/gdb/build-git/all-targets/gdb/gdb cfiles, some s390 target description c files are not generated. This patch adds these s390 xml files to XMLTOC, so these c files can be generated. gdb: 2016-10-05 Yao Qi <yao.qi@linaro.org> * features/Makefile (XMLTOC): Add s390-tevx-linux64.xml, s390-vx-linux64.xml, s390x-tevx-linux64.xml and s390x-vx-linux64.xml.
2016-10-05Simplify i386, amd64 and x32 expedite registersYao Qi1-28/+3
Nowadays, there are a lot of duplication about i386/{i386, amd64, x32}*-expedite in features/Makefile. However, in features/Makefile, we have echo "expedite:$(if $($*-expedite),$($*-expedite),$($(firstword $(subst -, ,$(notdir $*)))-expedite))" \ >> $(outdir)/$*.tmp which means for a given bar/foo-baz.xml, we'll look for either bar/foo-baz-expedite or foo-expedite. In x86 expedite registers, we use the former now, but it will be much simpler if we use the latter. This is what this patch does. This patch removes them, and defines three generic expedite. Re-run 'make GDB=/path/build/gdb all' to regenerate regformats/*.dat files, and they are not changed. gdb: 2016-10-05 Yao Qi <yao.qi@linaro.org> * features/Makefile: Remove i386/*-expedite. Add i386-expedite, amd64-expedite, and x32-expedite.

2016-09-21arc: New Synopsys ARC portAnton Kolesov5-0/+333
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.

2016-08-08Regenerate some target description filesPedro Alves4-132/+132
I regenerated all target description .c files from scratch, and got this spurious diff. It's a simple mid-air collision - these files were clearly generated before commit 73b4f516a037 ("maint_print_c_tdesc_cmd: Use type for TYPE_CODE_FLAGS instead of field_type."), which did the global s/field_type/type/, and pushed to master afterwards. gdb/features/ChangeLog: 2016-08-08 Pedro Alves <palves@redhat.com> * features/i386/amd64-avx-mpx-linux.c: Regenerate. * features/i386/amd64-avx-mpx.c: Regenerate. * features/i386/i386-avx-mpx-linux.c: Regenerate. * features/i386/i386-avx-mpx.c: Regenerate.

2016-04-19Re-factor (i386|amd64)mpx target descriptions.Walfred Tedeschi8-84/+24
In the previous patch a new set of target descriptions (i386|amd64)-avx-mpx were added being same as the (i386|amd64)-mpx. This patch removes AVX feature from (i386|amd64)-mpx target description set. This way the (i386|amd64)avx_mpx(_linux|) set has AVX and MPX features and (i386|amd64)mpx(_linux|) only MPX. 2016-04-14 Walfred Tedeschi <walfred.tedeschi@intel.com> * features/i386/amd64-mpx-linux.xml: Remove AVX feature. * features/i386/amd64-mpx.xml: Remove AVX feature. * features/i386/i386-mpx-linux.xml: Remove AVX feature. * features/i386/i386-mpx.xml: Remove AVX feature. * features/i386/amd64-mpx-linux.c: Regenerate. * features/i386/amd64-mpx.c: Regenerate. * features/i386/i386-mpx-linux.c: Regenerate. * features/i386/i386-mpx.c: Regenerate. * regformats/i386/amd64-mpx-linux.dat: Regenerate. * regformats/i386/amd64-mpx.dat: Regenerate. * regformats/i386/i386-mpx-linux.dat: Regenerate. * regformats/i386/i386-mpx.dat: Regenerate.
2016-04-19Add target descriptions for AVX + MPXWalfred Tedeschi9-0/+876
The current MPX target descriptions assume that MPX is always combined with AVX, however that's not correct. We can have machines with MPX and without AVX; or machines with AVX and without MPX. This patch adds new target descriptions for machines that support both MPX and AVX, as duplicates of the existing MPX descriptions. The following commit will remove AVX from the MPX-only descriptions. 2016-04-16 Walfred Tedeschi <walfred.tedeschi@intel.com> gdb/ChangeLog: * amd64-linux-tdep.c (features/i386/amd64-avx-mpx-linux.c): New include.

2015-07-07Set architecture to arm in arm-*.xml filesYao Qi12-0/+18
This patch is to add the following line to various arm target description xml files, <architecture>arm</architecture> in order to fix problems I've seen on aarch64 multi-arch debugging, detach^M Detaching from program: build-gdb/gdb/testsuite/gdb.base/attach, process 17145^M (gdb) PASS: gdb.base/attach.exp: attach1 detach file^M No executable file now.^M Architecture of file not recognized.^M (gdb) FAIL: gdb.base/attach.exp: attach1, purging symbols after detach Without this patch, struct target_desc *tdesc_* are not initialised properly, that is, fields arch and osabi in 'struct target_desc' are not set properly. This doesn't cause any problems on single arch debugging, because arch-utils.c:gdbarch_info_fill will guess correctly. However, in multi-arch debugging, gdbarch_info_fill gets the aarch64 arch, but the target description is for arm (because the current inferior is 32-bit arm). It is a surprise to me we didn't set architecture to "arm" before in *.xml files, and I didn't find out why didn't do so. AFAICS, gdb/features/arm-with-iwmmxt.xml was added firstly (in patch https://sourceware.org/ml/gdb-patches/2007-01/msg00593.html) which had <architecture>iwmmxt</architecture>, however, afterwards, architecture isn't set anymore in features/arm-*.xml files (in patches https://sourceware.org/ml/gdb-patches/2009-07/msg00689.html and https://sourceware.org/ml/gdb-patches/2010-08/msg00225.html). gdb: 2015-07-07 Yao Qi <yao.qi@linaro.org> * features/arm-with-m-fpa-layout.xml: Set architecture to arm. * features/arm-with-m-fpa-layout.c: Regenerated. * features/arm-with-m-vfp-d16.xml: Likewise. * features/arm-with-m-vfp-d16.c: Regenerated. * features/arm-with-m.xml: Likewise. * features/arm-with-m.c: Regenerated. * features/arm-with-neon.xml: Likewise. * features/arm-with-neon.c: Regenerated. * features/arm-with-vfpv2.xml: Likewise. * features/arm-with-vfpv2.c: Regenerated. * features/arm-with-vfpv3.xml: Likewise. * features/arm-with-vfpv3.c: Regenerated.

2015-02-27Exported const objectsPedro Alves1-1/+7
const works different in C vs C++. In C++, a global "const" variable has internal linkage by default, resulting in link errors like: ... extension.o: In function `get_ext_lang_defn(extension_language)': gdb/extension.c:126: undefined reference to `extension_language_guile' gdb/extension.c:124: undefined reference to `extension_language_guile' ... The fix is to define exported const objects with "extern const". But that in C would not be a definition. So we need to #ifdef C vs C++ in this case. EXPORTED_CONST comes from include/ansidecl.h, but in the feature_to_c.sh case I think it's better to leave the script with no dependencies. gdb/ChangeLog: 2015-02-27 Pedro Alves <palves@redhat.com> * cp-valprint.c (vtbl_ptr_name): Use EXPORTED_CONST. * guile/guile.c (extension_language_guile): Use EXPORTED_CONST. * features/feature_to_c.sh: Tag the generated xml_builtin array with extern const in C++ mode.
2015-02-09record-btrace: add bts buffer size configuration optionMarkus Metzger1-0/+1
Allow the size of the branch trace ring buffer to be defined by the user. The specified buffer size will be used when BTS tracing is enabled for new threads. The obtained buffer size may differ from the requested size. The actual buffer size for the current thread is shown in the "info record" command. Bigger buffers mean longer traces, but also longer processing time. 2015-02-09 Markus Metzger <markus.t.metzger@intel.com> * btrace.c (parse_xml_btrace_conf_bts): Add size.

2015-02-09record btrace: add configuration structMarkus Metzger1-0/+10
Add a struct to describe the branch trace configuration and use it for enabling branch tracing. The user will be able to set configuration fields for each tracing format to be used for new threads. The actual configuration that is active for a given thread will be shown in the "info record" command. At the moment, the configuration struct only contains a format field that is set to the only available format. The format is the only configuration option that can not be set via set commands. It is given as argument to the "record btrace" command when starting recording. 2015-02-09 Markus Metzger <markus.t.metzger@intel.com> * Makefile.in (XMLFILES): Add btrace-conf.dtd. * x86-linux-nat.c (x86_linux_enable_btrace): Update parameters.

2014-10-01features/Makefile: Make 'make cfiles' default to generating all C filesPedro Alves1-4/+118
This makes it easier to rebuild all GDB's generated target description C files. It also clarifies the comments a bit. One might think we need a GDB configured for the particular arquitecture (--target=foo). But a build that includes support for the target description is sufficient. (GDB rejects target descriptions that explicitly specify the architecture, with an <architecture> element, if the architecture is unknown.) Tested that "make clean-cfiles" deletes all .c files under src/gdb/features/, and that "make cfiles" generates them all without error, and that diffing the newly generated C files against master comes out an empty diff. gdb/ 2014-10-01 Pedro Alves <palves@redhat.com> * features/Makefile: Update comments.

The only reason .dat files exist is for GBBserver to use them in its build system. A few .dat files are listed as targets for generation that shouldn't. The target descriptions these files are built from aren't used by GDBserver. They're fallback descriptions GDB itself has baked in. Remove them from the list of .dat files to be generated, otherwise a plain "make" under src/gdb/features/ generates new .dat files that aren't even in the tree today. gdb/ 2014-10-01 Pedro Alves <palves@redhat.com> * features/Makefile (WHICH): Remove arm-with-m, arm-with-m-fpa-layout and arm-with-m-vfp-d16.

2014-10-01Aarch64: Make CPSR a 32-bit register again in the target descriptionPedro Alves2-2/+2
This reverts commit a4d9ba85 - 'AARCH64: Change cpsr type to be 64bit.'. Even though Linux's ptrace exposes CPSR as 64-bit, CPSR is really 32-bit, and basing GDB's fundamentals on a particular OS's ptrace(2) implementation is a bad idea. In addition, while that commit intended to fix big endian Aarch64, it ended up breaking floating point debugging against GDBserver, for both big and little endian, because it changed the CPSR to be 64-bit in the features/aarch64-core.xml file, but missed regenerating the regformats/aarch64.dat file. If we generate it now, we see this: diff --git c/gdb/regformats/aarch64.dat w/gdb/regformats/aarch64.dat index afe1028..0d32183 100644 --- c/gdb/regformats/aarch64.dat +++ w/gdb/regformats/aarch64.dat @@ -35,7 +35,7 @@ expedite:x29,sp,pc 64:x30 64:sp 64:pc -32:cpsr +64:cpsr 128:v0 128:v1 128:v2 IOW, that commit left regformats/aarch64.dat still considering CPSR as 32-bits. regformats/aarch64.dat is used by GDBserver for its internal regcache layout, and for the g/G packet register block. See the generated aarch64.c file in GDBserver's build dir. So the target description xml file that GDBserver reports to GDB is now claiming that CPSR is 64-bit, but what GDBserver actually puts in the g/G register packets is 32-bits. Because GDB thinks CPSR is 64-bit (because that's what the XML description says), GDB will be reading the remaining 32-bit bits of CPSR out of v0 (the register immediately afterwards), and then all the registers that follow CPSR in the register packet end up wrong in GDB, because they're being read from the wrong offsets... gdb/ 2014-10-01 Pedro Alves <palves@redhat.com> * features/aarch64-core.xml (cpsr): Change back to 32-bit. * features/aarch64.c: Regenerate.
2014-07-19Fix for remote G Packet message too long error for baremetal.Michael Eager7-0/+258
Prior to version MicroBlaze v8.10.a,EDK 13.1, XMD's gdbserver stub returned 57 registers in response to GDB's G request. Starting with version MicroBlaze v8.10.a, EDK 13.1, XMD added the slr and shr register, for a count of 59 registers. This patch adds these registers to the expected G response.

2014-04-24Add AVX512 registers support to GDB and GDBserver.Michael Sturm15-0/+1953
This patch adds support for the Intel(R) Advanced Vector Extensions 512 (Intel(R) AVX-512) registers. Native and remote debugging are covered by this patch. Intel(R) AVX-512 is an extension to AVX to support 512-bit wide SIMD registers in 64-bit mode (XMM0-XMM31, YMM0-YMM31, ZMM0-ZMM31). The number of available registers in 32-bit mode is still 8 (XMM0-7, YMM0-7, ZMM0-7). The lower 256-bits of the ZMM registers are aliased to the respective 256-bit YMM registers. The lower 128-bits are aliased to the respective 128-bit XMM registers. There are also 8 new, dedicated mask registers (K0-K7) in both 32-bit mode and 64-bit mode.

2013-05-29[AArch64] Remove all traces of aarch64-without-fpu.xml.Pedro Alves3-68/+1
The aarch64-without-fpu description is unused. Linux requires an FPU, so the AArch64 native port always returns the with-fpu variant: static const struct target_desc * aarch64_linux_read_description (struct target_ops *ops) { initialize_tdesc_aarch64 (); return tdesc_aarch64; } When the target doesn't report a target description at all, we fallback to a register set with an FPU: aarch64_gdbarch_init () ... if (!tdesc_has_registers (tdesc)) tdesc = tdesc_aarch64; This just removes the dead description. Tested by building on x86_64 Fedora 17 with --enable=targets=all. gdb/ 2013-05-29 Pedro Alves <palves@redhat.com> * aarch64-tdep.c: Don't include "features/aarch64-without-fpu.c".
