$ arm-eabi-gcc -c -mfloat-abi=softfp -mfpu=neon -flto -user-linker-plugin -c neon-intrinsics.c neon-intrinsics.c:7:1: sorry, unimplemented: gimple bytecode streams do not support machine specific builtin functions on this target
I think this is because the Neon intrinsics are not streamed out into the gimple bytecode stream and needed to be re-factored to allow these builtins to be streamed out for use with LTO.
There are a set of patches from Jie Zhang regarding refactoring neon builtins to allow this streaming to happen that is awaiting review upstream.

cheers Ramana
I'm afraid I don't know what the fix is. Anyone else?
