    PR 65138/target
    * config/rs6000/rs6000-cpus.def (powerpc64le): Add new generic
    processor type for 64-bit little endian PowerPC.

    * config/rs6000/rs6000.c (rs6000_option_override_internal): If
    -mdebug=reg, print TARGET_DEFAULT.  Fix logic to use
    TARGET_DEFAULT if there is no default cpu.  Fix -mdebug=reg
    printing built-in mask so it does not pass NULL pointers.

    * config/rs6000/rs6000-tables.opt: Regenerate.

    * doc/invoke.texi (IBM RS/6000 and PowerPC options): Document
    -mcpu=powerpc64le.

    Backport from trunk
    2015-01-19  David Edelsohn  <dje.gcc@gmail.com>

    * config/rs6000/default64.h: Include rs6000-cpus.def.
    (TARGET_DEFAULT) [LITTLE_ENDIAN]: Use ISA 2.7 (POWER8).
    (TARGET_DEFAULT) [BIG_ENDIAN]: Use POWER4.
    * config/rs6000/driver-rs6000.c (detect_processor_aix): Add POWER7
    and POWER8.
    * config/rs6000/linux64.h (PROCESSOR_DEFAULT64): Always default to
    POWER8.
    * config/rs6000/rs6000.c (rs6000_file_start): Emit .machine
    pseudo-op to specify assembler dialect.
