Function Documentation

◆ 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.

◆ MaxInterleaveGroupFactor

cl::opt<unsigned> MaxInterleaveGroupFactor("max-interleave-group-factor", cl::Hidden, cl::desc("Maximum factor for an interleaved access group (default = 8)"), cl::init(8))
static

Maximum factor for an interleaved memory access.
