On the LLVM list, Tim (ARM) is trying to push a patch to update the polynomial types on NEON to unsigned, on both 32-bits and 64-bits, since AArch32 says nothing and AArch64 specifies unsigned (char and short).

Is there any such movement on the GCC end? The LLVM folks would rather this be a common move (or GCC first), than going solo and risk losing ABI compatibility.

Any comments?

cheers,
