addToAccessGroupList()

template<typename ListT >

static void addToAccessGroupList ( ListT &  List, MDNode *  AccGroups  )

static

Add all access groups in AccGroups to List.

concatenateTwoVectors()

static Value * concatenateTwoVectors ( IRBuilderBase &  Builder, Value *  V1, Value *  V2  )

static

A helper function for concatenating vectors.

This function concatenates two vectors having the same element type. If the second vector has fewer elements than the first, it is padded with undefs.
