Hi,Attached is a patch that implements the framework necessary for implementing NEON Intrinsics' builtins in Tree/Gimple rather than RTL. For this it uses the target hook TARGET_FOLD_BUILTIN and folds all the builtins for NEON Intrinsics into equivalent trees. This framework is accompanied by an example implementation of vaddv<q>_f<32, 64> intrinsics using the framework. Regression tested on aarch64-none-elf. OK for trunk? Thanks, Tejas Belagod ARM.

I think we need to wait for a resolution to this thread: http://gcc.gnu.org/ml/gcc-patches/2013-03/msg00505.html before we can take this patch. /Marcus
