SmallVector< Type, 5 > LLVMTypeConverter::getMemRefDescriptorFields | ( | MemRefType | type, |
bool | unpackAggregates | ||
) | const |
Convert a memref type into a list of LLVM IR types that will form the memref descriptor.
If unpackAggregates
is true the sizes
and strides
arrays in the descriptors are unpacked to individual index-typed elements, else they are kept as rank-sized arrays of index type. In particular, the list will contain:
For example, memref<?x?xf32> is converted to the following list:
!llvm<"float*">
(allocated pointer),!llvm<"float*">
(aligned pointer),i64
(offset),i64
, i64
(sizes),i64
, i64
(strides). These types can be recomposed to a memref descriptor struct.
The result contains the following types:
index
-type integer containing the distance between the beginning of the buffer and the first element to be accessed through the view, followed byindex
-type integers as the rank of the MemRef: the array represents the size, in number of elements, of the memref along the given dimension. For constant MemRef dimensions, the corresponding size entry is a constant whose runtime value must match the static value, followed byindex
-type integers as the rank of the MemRef: the second array represents the "stride" (in tensor abstraction sense), i.e. the number of consecutive elements of the underlying buffer. TODO: add assertions for the static cases.If unpackAggregates
is set to true, the arrays described in (4) and (5) are expanded into individual index-type elements.
template <typename Elem, typename Index, size_t Rank> struct { Elem *allocatedPtr; Elem *alignedPtr; Index offset; Index sizes[Rank]; // omitted when rank == 0 Index strides[Rank]; // omitted when rank == 0 };
