OwningMemRef() [1/4]

template<typename T , unsigned Rank>

mlir::OwningMemRef< T, Rank >::OwningMemRef ( ArrayRef< int64_t >  shape, ArrayRef< int64_t >  shapeAlloc = {}, ElementWiseVisitor< T >  init = {}, std::optional< uint64_t >  alignment = std::optional<uint64_t>(), AllocFunType  allocFun = &::malloc, std::function< void(StridedMemRefType< T, Rank >)>  freeFun = [](StridedMemRefType<T, Rank> descriptor) { ::free(descriptor.data); }  )

inline

Allocate a new dense StridedMemrefRef with a given shape.

An optional shapeAlloc array can be supplied to "pad" every dimension individually. If an ElementWiseVisitor is provided, it will be used to initialize the data, else the memory will be zero-initialized. The alloc and free method used to manage the data allocation can be optionally provided, and default to malloc/free.
