Remove broken nios2 assembler dwim support.
2014-11-28 Sandra Loosemore <sandra@codesourcery.com> include/opcode/ * nios2.h (NIOS2_INSN_ADDI, NIOS2_INSN_ANDI): Delete. (NIOS2_INSN_ORI, NIOS2_INSN_XORI): Delete. (NIOS2_INSN_OPTARG): Renumber. opcodes/ * nios2-opc.c (nios2_r1_opcodes): Remove deleted attributes from descriptors. gas/ * config/tc-nios2.c (can_evaluate_expr, get_expr_value): Delete. (output_addi, output_andi, output_ori, output_xori): Delete. (md_assemble): Remove calls to deleted functions. gas/testsuite/ * gas/nios2/nios2.exp: Make "movi" a list test. * gas/nios2/movi.s: Adjust comments, add another case. * gas/nios2/movi.l: New. * gas/nios2/movi.d: Delete.
