getIndexedTypeInternal()

template<typename IndexTy >

static Type* getIndexedTypeInternal ( Type *  Agg, ArrayRef< IndexTy >  IdxList  )

static

getIndexedType - Returns the type of the element that would be accessed with a gep instruction with the specified parameters.

The Idxs pointer should point to a continuous piece of memory containing the indices, either as Value* or uint64_t.

A null type is returned if the indices are invalid for the specified pointer type.
