addVariantDeclaration()

static void addVariantDeclaration ( CallInst &  CI, const ElementCount &  VF, const StringRef  VFName  )

static

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

The TLI assumes that all parameters and the return type of CI (other than void) need to be widened to a VectorType of VF lanes.
