# powerpc and powerpc64 common options

if ARCH_powerpc || ARCH_powerpc64

config ARCH_POWERPC_SPE

    bool

    prompt "Enable SPE support"

    default n

    help

      Add support for the Signal Processing Engine.  This will set up

      the toolchain so that it supports the SPE ABI extensions. This

      mainly targets Freescale e500 processors.

      Setting this option will append "spe" to the end of your target

      tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc

      configure/build system will know to include SPE ABI support.

      It will also automatically add "-mabi=spe -mspe" to your

      TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,

      so you do not need to explicitly add them.
