2016-11-03arc: Change max instruction length to 64-bitsAndrew Burgess1-1/+1
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.
