gdb/ChangeLog: Update copyright year range in all GDB files
2017-12-21Do not emit "field_type" var if not needed on "maint print c-tdesc"Simon Marchi
While fiddling a bit with -Wunused-variable, Sergio noticed that "maint print c-tdesc" was always generating code for the "tdesc_type *field_type" variable, even when it wasn't used. This is caught by GCC when using -Wunused-variable, of course. This patch changes the print_c_tdesc class to only output the field declaration when we actually need it. It shouldn't be necessary to do the same with the other variable declarations (type_with_fields and element_type), because they are always if they are declared. The C files in features/ are regenerated, some declarations of field_type are removed, as expected, while some others move to where they are used for the first time. gdb/ChangeLog: * target-descriptions.c (print_c_tdesc) <visit>: Don't output field_type declaration, use printf_field_type_assignment instead. <printf_field_type_assignment>: New method. * features/aarch64-core.c, features/aarch64-fpu.c features/arc-arcompact.c, features/arc-v2.c, features/arm/arm-with-iwmmxt.c, features/i386/32bit-core.c, features/i386/32bit-mpx.c, features/i386/32bit-sse.c, features/i386/64bit-avx512.c, features/i386/64bit-core.c, features/i386/64bit-mpx.c, features/i386/64bit-sse.c, features/i386/x32-core.c, features/or1k.c, features/rs6000/powerpc-7400.c, features/rs6000/powerpc-altivec32.c, features/rs6000/powerpc-altivec32l.c, features/rs6000/powerpc-altivec64.c, features/rs6000/powerpc-altivec64l.c, features/rs6000/powerpc-cell32l.c, features/rs6000/powerpc-cell64l.c, features/rs6000/powerpc-isa205-altivec32l.c, features/rs6000/powerpc-isa205-altivec64l.c, features/rs6000/powerpc-isa205-vsx32l.c, features/rs6000/powerpc-isa205-vsx64l.c, features/rs6000/powerpc-vsx32.c, features/rs6000/powerpc-vsx32l.c, features/rs6000/powerpc-vsx64.c, features/rs6000/powerpc-vsx64l.c, features/s390-gs-linux64.c, features/s390-tevx-linux64.c, features/s390-vx-linux64.c, features/s390x-gs-linux64.c, features/s390x-tevx-linux64.c, features/s390x-vx-linux64.c: Re-generate.
2017-12-12gdb: Add OpenRISC or1k and or1knd target supportFranck Jullien
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.
2017-12-05Split tdesc_type into multiple classesSimon Marchi
This patch makes tdesc_type an abstract base class and creates three subclasses: - tdesc_type_builtin, for builtin types - tdesc_type_vector, for vector types - tdesc_type_with_fields, for struct, union, flag and enum types This allows getting rid of the union in tdesc_type and to not allow the std::vector separately. I tried to go further and create separate classes for struct, union, flag and enum, but it proved too difficult. One problem is that from the point of the of the target description code, the types tdesc_type_* are opaque (only forward-declared). Therefore, it doesn't know about inheritance relationship between those classes. This makes it impossible to make functions that accept a pointer to a base class and pass a pointer to a derived class, for example. I think this patch here is a good compromise, and if somebody wants to improve things further, the door is open. A make_gdb_type virtual pure method is added to tdesc_type, which replaces the current tdesc_gdb_type function. Calling this method on a tdesc_type returns the corresponding built gdb type. gdb/ChangeLog: * target-descriptions.c (struct tdesc_type): Use default destructor. <u>: Remove. <accept>: Remove.

2017-12-05Make tdesc_reg string fields std::stringSimon Marchi
Make the name, group and type fields of tdesc_reg std::strings. This way, we don't have to manually free them in ~tdesc_reg. Doing so results in a small change in the generated tdesc. Instead of passing an empty string for the group parameter of tdesc_create_reg, the two modified tdesc now pass NULL. The end result should be the same. gdb/ChangeLog: * target-descriptions.c (struct tdesc_reg) <tdesc_reg>: Change type of name_ parameter, adjust to std::string change. <name, group, type>: Change type to std::string. <~tdesc_reg>: Replace with default implementation. <operator==>: Adjust.

features/*.c are generated from *.xml files, in order to get pre-defined target descriptions, (for native debugging, for example). However, these pre-generated tdesc_tic6x_* are not used in GDB at all.

2017-10-13Simplify tic6x and s390x expedite registersYao Qi
Nowadays, we have six tic6x expedite registers, which are duplicated. tic6x-c64xp-expedite = A15,PC tic6x-c64x-expedite = A15,PC tic6x-c62x-expedite = A15,PC tic6x-c64xp-linux-expedite = A15,PC tic6x-c64x-linux-expedite = A15,PC tic6x-c62x-linux-expedite = A15,PC 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. We can define only one generic expedite register for all different ti6cx and s390x target descriptions. Actually, we've done that for x86 target descriptions. Re-run 'make GDB=/path/build/gdb all' to regenerate regformats/*.dat files, and they are not changed. gdb: 2017-10-13 Yao Qi <yao.qi@linaro.org> * features/Makefile: Remove tic6x-*-expedite, add tic6x-expedite. Remove s390x-*-expedite, add s390x-expedite.

2017-09-05Dynamically composite xml in reply to GDBYao Qi
GDBserver still uses pre-generated target descriptions in order to reply to GDB's query on target description (see xml-builtin-generated.c in GDBserver build directory). This patch teaches GDBserver to create XML contents according to the target descriptions rather than using pre-generated ones. First, change target feature c files to pass the feature xml file name to tdesc_create_feature, so that target description in GDBserver can record them, and create XML contents from these features in buffer, like ... <xi:include href="$FEATURE1_XML_NAME"/> <xi:include href="$FEATURE2_XML_NAME"/> ... and send this buffer back to GDB. Note that this patch reuses target_desc.xmltarget a little bit, which is to hold the XML contents dynamically generated in tdesc_get_features_xml. However, it is not xfree'ed in ~target_desc, because we can't tell it is from xstrdup or a literal string. Since we don't delete target_desc, there is no memory leak yet. After we change all target descriptions to the new style, target_desc.xmltarget is from xstrdup, then, we can safely xfree it in ~target_desc. gdb: 2017-09-05 Yao Qi <yao.qi@linaro.org> * arch/tdesc.h (tdesc_create_feature): Add an argument xml. * target-descriptions.c (tdesc_create_feature): Likewise, and adjust code. * features/i386/32bit-avx.c: Re-generated. * features/i386/32bit-avx512.c: Re-generated. * features/i386/32bit-core.c: Re-generated. * features/i386/32bit-linux.c: Re-generated. * features/i386/32bit-mpx.c: Re-generated. * features/i386/32bit-pkeys.c: Re-generated. * features/i386/32bit-sse.c: Re-generated. gdb/gdbserver: 2017-09-05 Yao Qi <yao.qi@linaro.org> * linux-x86-tdesc.c: Don't include <inttypes.h>.

2017-07-26Lazily and dynamically create i386-linux target descriptionsYao Qi
Instead of using pre-generated target descriptions, this patch changes GDB to lazily and dynamically create target descriptions according to the target hardware capability (xcr0 in i386). This support any combination of target features. Some reg in target description has "regnum" attribute, so its register number is got from the attribute value instead from sequential allocation. <reg name="xmm0" bitsize="128" type="vec128" regnum="32"/> when target description is created, it should match the regnum, so this patch adds a new field m_next_regnum to track it, if attribute number is greater than the m_next_regnum, print the code to set register number explicitly. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * i386-linux-tdep.c: Don't include features/i386/i386-*linux.c.

2017-07-26Generate c for feature instead of tdescYao Qi
This patch changes Makefile and command "maint print c-files" so that GDB can print c files for features instead target description. Previously, we feed GDB a target description xml file, which generate c files including multiple features. With this patch, in Makefile, we wrap each feature xml file, and create a temp target description which include only one feature. Then, adjust the target description printer for them, and print a c function for each given feature, so that we can use these c functions later to create target description in a flexible way. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * features/Makefile (CFILES): Rename with TDESC_CFILES.

2017-07-26Use visitor pattern for "maint print c-tdesc"Yao Qi
Target description can be modeled as a tree, the target description is the root node, features are children nodes, registers and types are grand-children nodes. So command "maint print c-tdesc" in effect traverse/visit each node, and print them in c. This can be implemented by visitor pattern, this is the first reason. Secondly, I want to this command prints c files in a different way for some specific xml files, but still print c files the same way for the rest of xml files. Third, I even want to print xml files from target descriptions, so that GDBserver can use it to reply GDB's query qXfer:features:read:target.xml. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * target-descriptions.c (tdesc_element_visitor): New class.

2017-07-26Add optional argument to command "maint prints c-tdesc"Yao Qi
Nowadays, we need two steps to print c files for xml target description, that is, 1) read xml target description in, update the current tdesc, 2) visit the current tdesc, print the c file. It is unnecessary to involve in current tdesc, and some validations in each gdbarch are performed unnecessarily, which will reject some target descriptions if they are missing some mandatory feature. This patch adds an optional argument to "maint print c-tdesc", which is an XML file target description, so that we can combine the two steps above into one step, and don't have to involve in global current tdesc. gdb: 2017-07-26 Yao Qi <yao.qi@linaro.org> * NEWS: Mention it. * features/Makefile (%.c: %.xml): Pass the xml file name to command "maint print c-tdesc". * target-descriptions.c (maint_print_c_tdesc_cmd): Get file name from 'arg'. gdb/doc: 2017-07-26 Yao Qi <yao.qi@linaro.org> * gdb.texinfo (Maintenance Commands): Document optional argument of "maint print c-tdesc".

2017-02-17Add support for Intel PKRU register to GDB and GDBserver.Michael Sturm
This patch adds support for the registers added by the Memory Protection Keys for Userspace (PKU aka PKEYs) feature. Native and remote debugging are covered by this patch. The XSAVE area is extended with a new state containing the 32-bit wide PKRU register. The new register is added to amd64-avx-mpx_avx512-* tdesc, thus it is renamed accordingly. Also, respective xstate mask X86_XSTATE_AVX_MPX_AVX512_MASK is renamed to X86_XSTATE_AVX_MPX_AVX512_PKU_MASK to reflect the new feature set it supports.

2017-02-17Add target description for avx-avx512.Michael Sturm
Add a dedicated target description for the feature combination avx-avx512 as implemented by certain IA CPU models. The corresponding X86_XSTATE_AVX_AVX512_MASK already exists, but shared the tdesc with X86_XSTATE_AVX_MPX_AVX512_MASK. This caused MPX registers displayed as undefined on CPUs that only implemented X86_XSTATE_AVX_AVX512_MASK, which is undesired. This patch solves this issue. This patch also corrects the wrong usage of x32-avx-mpx-avx512, which is replaced by x32-avx-avx512. The MPX feature is not implemented in x32 mode. gdb/Changelog: 2016-04-18 Michael Sturm <michael.sturm@intel.com> * amd64-linux-tdep.c (features/i386/amd64-avx-avx512-linux.c): New include.

2017-02-17Rename target descriptions to reflect actual content of description.Michael Sturm
To better reflect the actual feature set covered by the IA target descriptions, the existing descriptions are renamed. Each feature of the extended state is added to the name of a description or xstate mask starting from AVX. For example, amd64-mpx-avx512-linux becomes amd64-avx-mpx-avx512-linux, while amd64-avx-linux remains unchanged. Likewise, the corresponding xstate masks are changed, e.g. from X86_XSTATE_MPX_AVX512_MASK to X86_XSTATE_AVX_MPX_AVX512_MASK. gdb/Changelog: 2016-04-18 Michael Sturm <michael.sturm@intel.com> * amd64-linux-tdep.c (features/i386/amd64-avx512-linux.c): Rename include to...

2016-10-05Simplify i386, amd64 and x32 expedite registersYao Qi
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.

2016-09-21arc: New Synopsys ARC portAnton Kolesov
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.

2016-04-19Re-factor (i386|amd64)mpx target descriptions.Walfred Tedeschi
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 Tedeschi
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.
