# powerpc specific configuration file config ARCH_powerpc_ABI string default "" if ARCH_powerpc_ABI_DEFAULT default "eabi" if ARCH_powerpc_ABI_EABI default "spe" if ARCH_powerpc_ABI_SPE choice bool prompt "ABI" default ARCH_powerpc_ABI_DEFAULT config ARCH_powerpc_ABI_DEFAULT bool prompt "default" help The default ABI (System V.4). config ARCH_powerpc_ABI_EABI bool prompt "EABI" depends on BARE_METAL help The Embedded ABI (stack alignment of 8 bytes, etc). config ARCH_powerpc_ABI_SPE bool prompt "SPE" help 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. endchoice
