I don't see any listed in the Using GCC manual, for either 4.7.3 or 4.8.3,
the two versions I've been working with. The instruction set has lots of
instructions for operating on pairs of 16-bit integers. So far, I've been
writing my own inline functions wrapping asm statements, but I'm wondering
if there are any undocumented intrinsics for these instructions in the
compiler.
It would also be nice if it knew how to add and subtract vectors of two
shorts using the built-in sadd16 and ssub16 instructions, but it doesn't
appear to do that. Are any of the ARM GCC gurus working on that?
