GCC already solved it: https://gcc.gnu.org/onlinedocs/gcc/Vector-Extensions.html The operations behave like C++ valarrays. Addition is defined as the addition of the corresponding elements of the operands. For example, in the code below, each of the 4 elements in a is added to the corresponding 4 elements in b and the resulting vector is stored in c.
And these are also available in clang. https://clang.llvm.org/docs/LanguageExtensions.html#vectors-...:
“Vectors and Extended Vectors
Supports the GCC, OpenCL, AltiVec, NEON, SVE and RVV vector extensions”
Thanks!
