> Subject: [PATCH 6/6] arc/nps400: Add new control instructions
>
> Add some new control instructions to the opcodes library, and a new test
> for these new instructions to the assembler. The new instructions use
> an instruction flag longer than any seen before (on arc), and so the max
> flag length is extended to accommodate this.
>
> gas/ChangeLog:
>
> * config/tc-arc.h (MAX_FLAG_NAME_LENGTH): Increase to 7.
> * testsuite/gas/arc/nps400-2.d: New file.
> * testsuite/gas/arc/nps400-2.s: New file.
>
> opcodes/ChangeLog:
>
> * arc-nps400-tbl.h: Add schd, sync, and hwschd instructions.
> * arc-opc.c (arc_flag_operands): Add new flags.
> (arc_flag_classes): Add new classes.
