I have been working on a package of header files that elevate and simplify
programing of the PowerISA Vector extensions. This builds on and extends
the API provided by altivec.h and includes many of the PowerISA 3.0
(POWER9) operations that current compilers may not support.
It seemed like the SciTech SIG was the closest area of interest but I sure
there are others (Like extended precision arithmetic for crypto).
The project is available here: https://github.com/open-power-sdk/pveclib
Thanks for your consideration
