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_ARRAY, so you
|
|
do not need to explicitly add them.
