how do I use __builtin_pulp_dotsp2() in C?

Created by: edcarstens

I've been experimenting with these built-in C functions from Davide Schiavone's presentation, but I am having trouble with shortVec:

typedef short shortVec attribute ((vector_size (2))));

void runTests(void) { shortVec v1 = {5, 6}; ... }

warning: excess elements in vector initializer shortVec v1 = {5, 6}; ^
