No, that just adds the extra option of using -mfloat-abi=hard. The EABI default is -mfloat-abi=soft. You need either "softfp" (soft ABI, allow use of VFP registers) or "hard" to use VFP and NEON. It's my multilibs proposal that would make -mcpu=cortex-a8 imply -mfpu=neon -mfloat-abi=softfp. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=43001
