    1.22 +      Add support for the Signal Processing Engine.  This will set up
    1.23 +      the toolchain so that it supports the SPE ABI extensions. This
    1.24 +      mainly targets Freescale e500 processors.

    1.26 +      Setting this option will append "spe" to the end of your target
    1.27 +      tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
    1.28 +      configure/build system will know to include SPE ABI support.
    1.29 +      It will also automatically add "-mabi=spe -mspe" to your
    1.30 +      TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,
    1.31 +      so you do not need to explicitly add them.
