11 config ARCH_POWERPC_SPE
13 prompt "Enable SPE support (EXPERIMENTAL)"
14 depends on EXPERIMENTAL
17 Add support for the Signal Processing Engine. This will set up
18 the toolchain so that it supports the SPE ABI extensions. This
19 mainly targets Freescale e500 processors.
21 Setting this option will append "spe" to the end of your target
22 tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
23 configure/build system will know to include SPE ABI support.
24 It will also automatically add "-mabi=spe -mspe" to your
25 TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,
26 so you do not need to explicitly add them.
