binutils/ChangeLog:
* doc/binutils.texi: Document -Mvirt disassembler option. gas/ChangeLog: * config/tc-mips.c (struct mips_set_options): New ase_virt field. (mips_opts): Update for the new field. (file_ase_virt): New variable. (ISA_SUPPORTS_VIRT_ASE): New macro. (ISA_SUPPORTS_VIRT64_ASE): New macro. (MIPS_CPU_ASE_VIRT): New define. (is_opcode_valid): Handle ase_virt. (macro_build): Handle "+J". (validate_mips_insn): Likewise. (mips_ip): Likewise. (enum options): Add OPTION_VIRT and OPTION_NO_VIRT. (md_longopts): Add mvirt and mnovirt (md_parse_option): Handle OPTION_VIRT and OPTION_NO_VIRT. (mips_after_parse_args): Handle ase_virt field. (s_mipsset): Handle "virt" and "novirt". (mips_elf_final_processing): Add a comment about virt ASE might need a new flag. (md_show_usage): Print out the usage of -mvirt and mno-virt options. * doc/c-mips.texi: Document -mvirt and -mno-virt. Document ".set virt" and ".set novirt". gas/testsuite/ChangeLog: * gas/mips/mips.exp: Run virt and virt64 testcases. * gas/mips/virt.d: New file. * gas/mips/virt.s: New file. * gas/mips/virt64.d: New file. * gas/mips/virt64.s: New file. include/opcode/ChangeLog: * mips.h (OP_MASK_CODE10): Correct definition. (OP_SH_CODE10): Likewise. Add a comment that "+J" is used now for OP_*CODE10. (INSN_ASE_MASK): Update. (INSN_VIRT): New macro. (INSN_VIRT64): New macro opcodes/ChangeLog: * mips-dis.c (mips_arch_choices): Add INSN_VIRT to mips32r2 . Add INSN_VIRT and INSN_VIRT64 to mips64r2. (parse_mips_dis_option): Handle the virt option. (print_insn_args): Handle "+J". (print_mips_disassembler_options): Print out message about virt64. * mips-opc.c (IVIRT): New define. (IVIRT64): New define. (mips_builtin_opcodes): Add dmfgc0, dmtgc0, hypcall, mfgc0, mtgc0, tlbgr, tlbgwi, tlbginv, tlbginvf, tlbgwr, tlbgp VIRT instructions. Move rfe to the bottom as it conflicts with tlbgp.
