2017-06-24[ARM] Add support for ARMv8-R in assembler and readelfThomas Preud'homme41-132/+714
=== Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to add support for ARMv8-R in GAS: instructions, build attributes and readelf. === Patch description === Although some differences exist for system registers, from GAS point of view ARMv8-R supports the same instructions as ARMv8-A Aarch32 state and a subset of its extensions. This patch therefore introduce a new feature bit to distinguish the availability of the pan, ras and rdma extensions between ARMv8-A and ARMv8-R and allow crypto, fp and simd extensions to be used by ARMv8-R. Most of the changes are then in the testsuite to (i) rename source files and error output to be shared between ARMv8-A and ARMv8-R, (ii) rename files with expected output for ARMv8-A build attributes and (iii) add new files with expected output for ARMv8-R build attributes. 2017-06-24 Thomas Preud'homme <thomas.preudhomme@arm.com> binutils/ * readelf.c (arm_attr_tag_CPU_arch): Fill value for ARMv8-R. gas/ * NEWS: Mention support for ARMv8-R architecture. * config/tc-arm.c (arm_archs): Add entry for ARMv8-R.

2017-06-24[ARM] Remove ARMv6S-M special casingThomas Preud'homme2-26/+24
=== Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to remove special casing for ARMv6S-M autodetection. === Motivation === Currently, SWI and SVC mnemonics are enabled for ARMv4T and successor architectures with extra checks in the handler function (do_t_swi) to give an error message when ARMv6-M is targeted and some more special casing in aeabi_set_public_attributes. This was made to exclude these mnemonics for ARMv6-M unless the OS extension is in use. However this logic is superfluous: there is already code to check whether an instruction is available based on the feature bit it is part of and whether the targeted architecture has that feature bit. This patch aims at removing that unneeded complexity. === Patch description === The OS extension is already limited to the ARMv6-M architecture so all this patch does is redefined availability of the ARM_EXT_OS feature bit to not be present for ARM_ARCH_V6M. ARM_ARCH_V6SM does not need any change either because it already includes ARM_EXT_OS. The patch also make sure that the error message that was given by do_t_swi when SWI/SVC is unavailable is still the same by detecting the situation in md_assemble. 2017-06-24 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (arm_ext_v6m): Delete.

2017-06-21[ARM] Rework Tag_CPU_arch build attribute value selectionThomas Preud'homme8-69/+231
=== Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to rework the Tag_CPU_arch build attribute value selection to (i) match architecture or CPU if specified by user without any need for hack and (ii) match an architecture with all the features used if in autodetection mode or return an error. === Motivation === Currently, Tag_CPU_arch build attribute value selection assumes that an architecture is always a superset of architectures released earlier. As such, the logic is to browse architectures in chronological order of release and selecting the Tag_CPU_arch value of the last one to contribute a feature used[1]/requested[2] not contributed by earlier architectures. [1] in case of autodetection mode [2] otherwise, ie. in case of -mcpu/-march or associated directives This logic fails the two objectives mentionned in the Context section. First, due to the assumption it does an architecture can be selected while not having all the features used/requested which fails the second objective. Second, not doing an exact match when an architecture or CPU is selected by the user means the wrong value is chosen when a later architecture provides a subset of the feature bits of an earlier architecture. This is the case for the implementation of ARMv8-R (see later patch). An added benefit of this patch is that it is possible to easily generate more consistent build attribute by setting the feature bits from the architecture matched in aeabi_set_public_attributes in autodetection mode. This is better done as a separate patch because lots of testcase' expected results must then be updated accordingly. === Patch description === The patch changes the main logic for Tag_CPU_arch and Tag_CPU_arch_profile values selection to: - look for an exact match in case an architecture or CPU was specified on the command line or in a directive - select the first released architecture that provides a superset of the feature used in the autodetection case - select the most featureful architecture in case of -march=all The array cpu_arch_ver is updated to include all architectures in order to make the first point work. Note that when looking for an exact match, the architecture with selected extension is tried first and then only the architecture. This is because some architectures are exactly equivalent to an earlier architecture with its extensions selected. ARMv6S-M (= ARMv6-M + OS extension) and ARMv6KZ (ARMv6K + security extension) are two such examples. Other adjustments are also necessary in aeabi_set_public_attributes to make this change work. 1) The logic to set Tag_ARM_ISA_use and Tag_THUMB_ISA_use must check the absence of feature bit used/requested to decide whether to give the default value for empty files (see EABI attribute defaults test). It was previously checking that arch == 0 which would only happen if no feature bit could be matched by any architecture, ie there is no feature bit to match. 2) A fallback to a superset match must exist when no_cpu_selected () returns true. This is because aeabi_set_public_attributes is called again after relaxation and at this point selected_cpu is set from the previous execution of that function. There is therefore no way to check whether the user specified an architecture or CPU. 3) Tag_CPU_arch lines are removed from expected output when the detected architecture should be pre-ARMv4, since 0 is the Tag_CPU_arch value for pre-ARMv4 architectures and default value for an absent entry is 0. 2017-06-21 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (fpu_any): Defined from FPU_ANY.

2017-06-21[ARM] Allow Thumb division as an extension for ARMv7Thomas Preud'homme4-0/+33
=== Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to allow ARMv7 to be selected in automatic architecture selection in presence of Thumb division instructions. === Motivation === any-idiv.d and automatic-sdiv.d testcases in GAS testsuite expect autodetection code to select ARMv7 in presence of Thumb integer division. However, the definition of ARM_AEXT_V7 and thus ARM_ARCH_V7 do not contain these instructions and the idiv extension is only available for ARMv7-A and ARMv7-R. Therefore, under the stricter automatic detection code proposed in the subsequent patch of the series ARMv7 is refused if a Thumb division instruction is present. === Patch description === This patch adds a new "idiv" extension after the existing one that is available to all ARMv7 targets. This new entry is ignored by all current code parsing arm_extensions such that it would be unavailable on the command-line and remain a purely internal hack, easily removed in favor of a better solution later. This is considered though by the subsequent patch reworking automatic detection of build attributes such that ARMv7 is allowed to match in present of Thumb division instructions. For good measure, comments are added in all instances of code browsing arm_extensions to mention the expected behavior in case of duplicate entries as well as a new testcase. 2017-06-20 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (arm_extensions): New duplicate idiv entry to enable Thumb division for ARMv7 architecture.

2017-06-21[ARM] Rework selection of feature bits to base build attributes onThomas Preud'homme2-16/+30
=== Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to set the feature bits on which to decide what the build attributes should be according to the mode (autodetection, user specified architecture or CPU, or -march/-mcpu=all). === Motivation === Currently, the flags variable which is used to determine the build attribute is constructed from the instruction used (arm_arch_used and thumb_arch_used) as well as the user specified architecture or CPU (selected_cpu). This means when several .arch are specified the resulting feature bits can be such that no architecture provide them all and can thus result in incorrect Tag_CPU_arch. See for instance what having both .arch armv8-a and .arch armv8-m.base would result in. This is not caught by the testsuite because of further bugs in the Tag_CPU_arch build attribute value selection logic (see next patch in the series). === Patch description === As one would expect, this patch solves the problem by setting flags from feature bits used if in autodetection mode [1] and from selected_cpu otherwise. The logic to set arm_ext_v1, arm_ext_v4t and arm_ext_os feature bits is also moved to only run in autodetection mode since otherwise the architecture or CPU would have a consistent set of feature bits already. [1] No architecture or CPU was specified by the user 2017-06-21 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (aeabi_set_public_attributes): Populate flags from feature bits used or selected_cpu depending on whether a CPU was selected by the user.
2017-06-21[ARM] Simplify Tag_DSP_extension selection logicThomas Preud'homme2-23/+11
=== Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to simplify the logic to decide whether to set Tag_DSP_extension. === Motivation === To decide whether to set Tag_DSP_extension, the current code was checking whether the flags had DSP instruction but the architecture selected for Tag_CPU_arch did not have any. This was necessary because extension feature bit were not available separately. This is no longer necessary and can be simplified. === Patch description === The patch change the logic to set Tag_DSP_extension to check whether any DSP feature bit is set in the extension feature bit, as per the definition of that build attribute. The patch also removes all definitions of arm_arch which is now unneeded. 2017-06-21 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (aeabi_set_public_attributes): Test *mcpu_ext_opt to decide whether to set Tag_DSP_extension build attribute value. Remove now useless arm_arch variable.
2017-06-21[ARM] Keep separation between extensions and architecture bits throughout ↵Thomas Preud'homme3-29/+101
execution === Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to keep the distinction between architecture feature bits and extension ones after parsing has occured. === Motivation === This distinction is necessary to allow the Tag_CPU_arch build attribute value to be exactly as per the architecture of the selected CPU. With mixed architecture and extension feature bit, it is impossible to find an architecture with an exact match of feature bit and the build attribute value logic must then select the closest match which might not be the right architecture. The previous patch in the patch series makes the distinction possible when parsing -mcpu and .cpu directives but the distinction gets lost after. Similarly feature bits contributed by extensions in -march or .arch_extensions directive are mixed together with architecture extensions. === Patch description === The patch adds new feature bit pointer for extension feature bits. Information from the parsing regarding extensions can then be kept separate in those. This requires adapting arm_parse_extension to deal with two feature bits, allowing the architecture bits to be marked as const. It also requires extra care when setting cpu_variant and selected_cpu because the extension bits are optional since there might not be any extension in use. Note that contrary to cpu feature bits, the extension feature bits are made read/write and are always dynamically allocated. This allows to unconditionally free them in arm_md_post_relax added for this occasion, thereby fixing a longstanding memory leak when arm_parse_extension was invoked (XNEW of ext_fset without corresponding XDELETE). Introduction of arm_md_post_relax is necessary to only free the extension feature bits after aeabi_set_attribute_string has been called for the last time. 2017-06-21 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (dyn_mcpu_ext_opt): New static variable.

2017-06-21[ARM] Separate extensions from architectures in arm_cpusThomas Preud'homme2-162/+381
=== Context === This patch is part of a patch series to add support for ARMv8-R architecture. Its purpose is to distinguish for a CPU the feature bits coming from its architecture from the feature bits coming from extension(s) available in this CPU. === Motivation === This distinction is necessary to allow the Tag_CPU_arch build attribute value to be exactly as per the architecture of the selected CPU. With mixed architecture and extension feature bit, it is impossible to find an architecture with an exact match of feature bit and the build attribute value logic must then select the closest match which might not be the right architecture. === Patch description === The patch creates a new field in the arm_cpus table to hold the feature set for the extensions available in each CPU. The existing architecture feature set is then updated to remove those feature bit. The patch also takes advantage of all the lines being changed to reindent the whole table. Note: This patch *adds* a memory leak due to mcpu_cpu_opt sometimes pointing to dynamically allocated feature bits which is never freeed. The subsequent patch in the series solves this issue as well as a preexisting identical issue in arm_parse_extension. The patches are kept separate for ease of review since they are both big enough already. 2017-06-21 Thomas Preud'homme <thomas.preudhomme@arm.com> gas/ * config/tc-arm.c (struct arm_cpu_option_table): New ext field.

2017-06-06[Patch, ARM] Relax the restrictions on REG_SP under Thumb mode on ARMv8-AJiong Wang12-18/+328
For Thumb mode, since ARMv8-A, REG_SP is allowed in most of the places in Rd/Rt/Rt2 etc while it was disallowed before ARMv8-A, and was rejected through the "reject_bad_reg" macro and several scattered checks. This patch only rejects REG_SP in "reject_bad_reg" and several related places for legacy architectures before ARMv8-A. I have checked those affected instructions , all of them qualify such relaxations. Testcases adjusted accordingly. * ld-sp-warn.d was written without .arch and without -march options passed. By default it assumes all architectures, so I deleted the REG_SP warning on ldrsb as it's supported on ARMv8-A.

This will allow reuse of CPU type definition in multiple places where it might be needed, for example in disassembler.
