2017-11-07opcodes/arc: Fix incorrect insn_class for some nps insnsAndrew Burgess1-4/+4

2016-11-04arc/nps400: Validate address type operands correctlyAndrew Burgess1-0/+14
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.

2016-11-03arc: Change max instruction length to 64-bitsAndrew Burgess1-14/+41
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.

2016-11-03arc/opcodes/nps400: Fix some instruction masksAndrew Burgess1-3/+3
A few masks were incorrect, there were opcode bits that lives outside of the instruction mask, the effected instructions are decode1, zncv, and efabgt. Previously these instructions would assemble and disassemble correctly, and a correctly encoded binary should behave no differently. The only difference would be seen in a few incorrectly encoded binaries, previously these would have decoded to the above instructions, while now they will not. opcodes/ChangeLog: * arc-nps400-tbl.h: Fix some instruction masks.
