Update check conditions for illegal placed instructions.
ARC cpus do not accept any jump or instructions with long immediate
into the delay slots.
gas/
2017-06-07 Claudiu Zissulescu <claziss@synopsys.com>
* /config/tc-arc.c (is_br_jmp_insn_p): Update macro with known
instructions to be accounted as jumps.
(assemble_insn): Check for limms into the delay slots. Emit an
error if so.
* testsuite/gas/arc/asm-errors-3.d: New file.
* testsuite/gas/arc/asm-errors-3.err: Likewise.
* testsuite/gas/arc/asm-errors-3.s: Likewise.
