yann@1634:       Add support for the Signal Processing Engine.  This will set up
yann@1634:       the toolchain so that it supports the SPE ABI extensions. This
yann@1634:       mainly targets Freescale e500 processors.
yann@1634:       
yann@1634:       Setting this option will append "spe" to the end of your target
yann@1634:       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
yann@2467:       configure/build system will know to include SPE ABI support. It
yann@2467:       will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS,
yann@2467:       and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you
yann@2467:       do not need to explicitly add them.
