Hi Mandeep,

I don't think we should be implementing old ARMCC intrinsics either. GCC doesn't, especially since most of them are easy to do with one line inline assembly snippets.

Those intrinsics are not covered by the ACLE (mentioned, but not defined), which reinforces the notion that we shouldn't be doing anyway.
