* config/tc-mips.c (mips_fix_loongson2f, mips_fix_loongson2f_nop,
mips_fix_loongson2f_jump): New variables. (md_longopts): Add New options -mfix-loongson2f-nop/jump, -mno-fix-loongson2f-nop/jump. (md_parse_option): Initialize variables via above options. (options): New enums for the above options. (md_begin): Initialize nop_insn from LOONGSON2F_NOP_INSN. (fix_loongson2f, fix_loongson2f_nop, fix_loongson2f_jump): New functions. (append_insn): call fix_loongson2f(). (mips_handle_align): Replace the implicit nops. * config/tc-mips.h (MAX_MEM_FOR_RS_ALIGN_CODE): Modified for the new mips_handle_align(). * doc/c-mips.texi: Document the new options. * gas/mips/loongson-2f-2.s: New test of -mfix-loongson2f-nop. * gas/mips/loongson-2f-2.d: Likewise. * gas/mips/loongson-2f-3.s: New test of -mfix-loongson2f-jump. * gas/mips/loongson-2f-3.d: Likewise. * gas/mips/mips.exp: Run the new tests. * opcode/mips.h (LOONGSON2F_NOP_INSN): New macro.
