Add support for the MIPS eXtended Physical Address (XPA) ASE.
ChangeLog: binutils/ * doc/binutils.texi: Document the disassemble MIPS XPA instructions command line option. gas/ * config/tc-mips.c (options): Add OPTION_XPA and OPTION_NO_XPA. (md_longopts): Add xpa and no-xpa command line options. (mips_ases): Add MIPS XPA ASE. (mips_cpu_info_table): Update p5600 entry to allow the XPA ASE. * doc/as.texinfo: Document the MIPS XPA command line options. * doc/c-mips.texi: Document the MIPS XPA command line options, and assembler directives. gas/testsuite/ * gas/mips/mips.exp: Add xpa tests. * gas/mips/xpa.s: New test. * gas/mips/xpa.d: Likewise. include/ * opcode/mips.h (ASE_XPA): New define. opcodes/ * mips-dis.c (mips_arch_choices): Update mips32r2 and mips64r2 to allow the MIPS XPA ASE. (parse_mips_dis_option): Process the -Mxpa option. * mips-opc.c (XPA): New define. (mips_builtin_opcodes): Add MIPS XPA instructions and move the locations of the ctc0 and cfc0 instructions.
