◆ addVariantDeclaration()

static void addVariantDeclaration ( CallInst CI,
const ElementCount VF,
const VecDesc VD 
)
static

A helper function that adds the vector variant declaration for vectorizing the CallInst CI with a vectorization factor of VF lanes.

For each mapping, TLI provides a VABI prefix, which contains all information required to create vector function declaration.
