* arc/nps400: Validate address type operands correctlyAndrew Burgess2016-11-041-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | When we match against an address type operand within an instruction it is important that we match exactly the right address type operand early on, during the opcode selection phase. If we wait until the operand insertion phase to check that we have the correct address operand, then it is too late to select an alternative opcode. This becomes important only when we have multiple opcodes with the same mnemonic, and operand lists that differ only in the type of the address operands. This commit fixes this issue, and adds some example instructions that require this issue to be fixed (the instructions are identical except for the address type operand). gas/ChangeLog: * config/tc-arc.c (find_opcode_match): Use insert function to validate matching address type operands. * testsuite/gas/arc/nps400-10.d: New file. * testsuite/gas/arc/nps400-10.s: New file. opcodes/ChangeLog: * arc-opc.c (arc_flag_operands): Add F_DI14.

* arc: Change max instruction length to 64-bitsAndrew Burgess2016-11-031-482/+300
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [ARC] Misc minor edits/fixesGraham Markall2016-06-231-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code supporting -mspfp, -mdpfp, and -mfpuda options are in sections of code that are commented as being for backward compatibility only, and having no effect. However, they do have an effect, enabling the SPX, DPX, and DPA instruction subclasses respectively. This commit moves the code supporting these options away from the comments indicating that they are dummy options, and also fixes a small issue where -mnps400 had the additional effect of enabling SPX instructions. A couple of other minor edits (that make no functional change) are also included. gas/ChangeLog: * config/tc-arc.c (options, md_longopts, md_parse_option): Move -mspfp, -mdpfp and -mfpuda out of the sections for dummy options.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit completes support for having multiple instructions with the same mnemonic in non-contiguous blocks within the arc_opcodes table.

* arc/opcodes: Use flag operand class to handle multiple flag matchesAndrew Burgess2016-03-211-25/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When parsing the operand instruction flags we don't currently detect the case where multiple flags are provided from the same class set, these will be accepted and the bit values merged together, resulting in the wrong instruction being assembled. For example: adc.n.eq r0,r0,r2 Will assemble without error, yet, upon disassembly, the instruction will actually be: adc.c r0,r0,r2 In a later commit the concept of required flags will be introduced. Required flags are just like normal instruction flags, except that they must be present for the instruction to match. Adding this will allow for simpler instructions in the instruction table, and allow for more sharing of operand extraction and insertion functions. To solve both of the above issues (multiple flags being invalid, and required flags), this commit reworks the flag class mechanism. Currently the flag class is never used. Each instruction can reference multiple flag classes, each flag class has a class type and a set of flags. However, at present, the class type is never used. The current values identify the type of instruction that the flag will be used in, but this is not required information. Instead, this commit discards the old flag classes, and introduces 3 new classes. The first F_CLASS_NONE, is just a NULL marker value, and is only used in the NULL marker flag class. The other two flag classes are F_FLAG_OPTIONAL, and F_FLAG_REQUIRED. The class F_FLAG_OPTIONAL has the property that at most one of the flags in the flag set for that class must be present in the instruction. The "at most" one means that no flags being present is fine. The class F_FLAG_REQUIRED is not currently used, but will be soon. With this class, exactly one of the flags from this class must be present in the instruction. If the flag class contains a single flag, then of course that flag must be present. However, if the flag class contained two or more, then one, and only one of them must be present. gas/ChangeLog: * config/tc-arc.c (find_opcode_match): Move lnflg, and i declarations to start of block.

* arc/gas: default mach is arc700, initialised in md_beginAndrew Burgess2016-03-211-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit restructures the selection of the default cpu/mach so that the choice is made from md_begin (if the user has not provided a command line choice). This will reduce the amount of change needed in a later patch. At the request of Synopsys, the default architecture changes to ARC700 from this commit, previously the default was a non-existent super-architecture that contained all instructions from all arc variants.
