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.
1.25 +
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.
