It is implemented in hardware on the z/Architecture, and our
compilers have natively supported that for many years.

We also have compilers that support it for x86 machines (both
32-bit and 64-bit) using the IBM DPD format.   Since it's not
native to the hardware those are supported via runtime functions.
