2020-07-14arc: Detect usage of illegal double register pairsClaudiu Zissulescu1-3/+11
ARC can use odd-even double register pairs in some selected instructions. Although the GNU assembler doesn't allow even-odd registers to be used, there may be cases when the disassembler is presented with such situation. This patch add a test and detects such cases. opcodes/ 2020-07-14 Claudiu Zissulescu <claziss@gmail.com> * arc-dis.c (print_insn_arc): Detect and emit a warning when a faulty double register pair is detected. binutils/ 2020-07-14 Claudiu Zissulescu <claziss@gmail.com> * testsuite/binutils-all/arc/double_regs.s: New test. * testsuite/binutils-all/arc/objdump.exp: Add the above test.

2017-06-29[ARC] Fix handling of cpu=... disassembler option valueAnton Kolesov1-8/+8
There is a bug in handling of cpu=... disassembler option in case there are other options after it, for example, `cpu=EM,dsp'. In this case `EM,dsp' is treated as an option value, and strcasecmp reports is as non-equal to "EM". This is fixed by using disassembler_options_cmp function, which compares string treating `,' the same way as `\0'. This function also solves a problem with option order in parse_option. Previously, if several option had same prefix (e.g. fpud, fpuda), then the longer one should have been compared first, otherwise when longer option is passed it would be treated as a short one, because CONST_STRNEQ ("fpud", "fpuda") would be true. The order of options was correct for ARC, so there were no bugs per se, but with disassembler_option_cmp there is no risk of such a bug being introduced in the future. opcodes/ChangeLog: yyyy-mm-dd Anton Kolesov <Anton.Kolesov@synopsys.com> * arc-dis.c (parse_option): Use disassembler_options_cmp to compare disassembler option strings.

2017-05-30[ARC] Allow CPU to be enforced via disassemble_info optionsAnton Kolesov1-26/+105
Currently print_insn_arc relies on BFD mach and ELF private headers to distinguish between various ARC architectures. Sometimes those values are not correct or available, mainly in the case of debugging targets without and ELF file available. Changing a BFD mach is not a problem for the debugger, because this is a generic BFD field, and GDB, for example, already sets it according to information provided in XML target description or specified via GDB 'set arch' command. However, things are more complicated for ELF private headers, since it requires existing of an actual ELF file. To workaround this problem this patch allows CPU model to be specified via disassemble info options. If CPU is specified in options, then it will take a higher precedence than whatever might be specified in ELF file. This is mostly needed for ARC EM and ARC HS, because they have the same "architecture" (mach) ARCv2 and differ in their private ELF headers. Other ARC architectures can be distinguished between each other purely via "mach" field. Proposed disassemble option format is "cpu=<CPU>", where CPU can be any valid ARC CPU name as supported by GAS. Note that this creates a seeming redundancy with objdump -m/--architecture option, however -mEM and -mHS still result in "ARCv2" architecture internally, while -Mcpu={HS,EM} would have an actual effect on disassembler. opcodes/ChangeLog: yyyy-mm-dd Anton Kolesov <anton.kolesov@synopsys.com> * arc-dis.c (enforced_isa_mask): Declare.

2016-11-03arc: Change max instruction length to 64-bitsAndrew Burgess1-282/+189
The current handling for arc instructions longer than 32-bits is all handled as a special case in both the assembler and disassembler. The problem with this approach is that it leads to code duplication, selecting a long instruction is exactly the same process as selecting a short instruction, except over more bits, in both cases we select based on bit comparison, and initial operand insertion and extraction. This commit unifies both the long and short instruction worlds, converting the core opcodes library from being largely 32-bit focused, to being largely 64-bit focused. The changes are, on the whole, not too much. There's obviously a lot of type changes but otherwise the bulk of the code just works. Most of the actual functional changes are to code that previously handled the longer 48 or 64 bit instructions. The insert/extract handlers for these have now been brought into line with the short instruction insert/extract handlers. All of the special case handling code that was previously added has now been removed again. Overall, this commit reduces the amount of code in the arc assembler and disassembler. gas/ChangeLog: * config/tc-arc.c (struct arc_insn): Change type of insn field.

2016-10-14[ARC] Disassembler: fix LIMM detection for short instructions.Claudiu Zissulescu1-2/+3
The ARC (short) instructions are using a special register number to indicate is the instruction uses a long immediate (LIMM). In the case of short instruction, this LIMM indicator depends on the ISA version used. Thus, for ARCv1 processors, the LIMM indicator is 0x3E, the same value used in "long" instructions. However, for the ARCv2 processors, this LIMM indicator is 0x1E. This patch fixes the LIMM detection for ARCv1 ISA and adds two tests. gas/ 2016-10-13 Claudiu Zissulescu <claziss@synopsys.com> * testsuite/gas/arc/shortlimm_a7.d: New file. * testsuite/gas/arc/shortlimm_a7.s: Likewise. * testsuite/gas/arc/shortlimm_hs.d: Likewise. * testsuite/gas/arc/shortlimm_hs.s: Likewise. include/ 2016-10-13 Claudiu Zissulescu <claziss@synopsys.com> * opcode/arc.h (ARC_OPCODE_ARCV2): New define. opcodes/ 2016-10-13 Claudiu Zissulescu <claziss@synopsys.com> * arc-dis.c (find_format_from_table): Discriminate LIMM indicator usage on ISA basis.

2016-09-16[ARC] Disassemble correctly extension instructions.Claudiu Zissulescu1-3/+3
For each MAJOR-MINOR opcode tuple, we can have either a 3-operand, or 2-operand, or a single operand instruction format, depending on the values present in i-field, and a-field. The disassembler is reading the section containing the extension instruction format and stores them in a table. Each table element represents a linked list with encodings for a particular MAJOR-MINOR tuple. The current implementation checks only against the first element of the list, hence, the issue. This patch is walking the linked list until empty or finds an opcode match. It also adds a test outlining the found problem. opcodes/ 2016-09-15 Claudiu Zissulescu <claziss@synopsys.com> * arc-dis.c (find_format): Walk the linked list pointed by einsn. gas/ 2016-09-15 Claudiu Zissulescu <claziss@synopsys.com> * testsuite/gas/arc/textinsnxop.d: New file. * testsuite/gas/arc/textinsnxop.s: Likewise.

2016-03-21arc: Add nps400 machine type, and assembler flag.Andrew Burgess1-0/+4
This commit introduces the nps400 machine type as a variant of arc. There's a new flag in the assembler to select this machine type. All other changes are just adding handling of the new machine type into the relevant places. The nps400 is an arc700 variant with some vendor specific instructions added into the instruction set. This commit does not add any of the new instructions, this is just laying the groundwork for future commits. However, in preparation for these new instructions a new opcode define for nps400 has been added to include/opcode/arc.h, this new opcode define is used in the assembler and disassembler along with the existing define for arc700 such that when assembling and disassembling for nps400 the user will have access to all arc700 instructions and all the nps400 vendor extension instructions. bfd/ChangeLog: * archures.c (bfd_mach_arc_nps400): Define. * bfd-in2.h: Regenerate. * cpu-arc.c (arch_info_struct): New entry for nps400, renumber some existing entries to make space. * elf32-arc.c (arc_elf_object_p): Add nps400 case. (arc_elf_final_write_processing): Likewise. binutils/ChangeLog: * readelf.c (decode_ARC_machine_flags): Handle nps400. gas/ChangeLog: * config/tc-arc.c (cpu_types): Add nps400 entry. (check_zol): Handle nps400. include/ChangeLog: * elf/arc.h (E_ARC_MACH_NPS400): Define. * opcode/arc.h (ARC_OPCODE_NPS400): Define. opcodes/ChangeLog: * arc-dis.c (print_insn_arc): Handle nps400.
