◆ getAssumedUniqueReturnOp()

static func::ReturnOp mlir::bufferization::func_ext::getAssumedUniqueReturnOp ( FuncOp  funcOp)

Return the unique ReturnOp that terminates funcOp.

Return nullptr if there is no such unique ReturnOp.

◆ getBufferizedFunctionArgType()

static BaseMemRefType mlir::bufferization::func_ext::getBufferizedFunctionArgType ( FuncOp  funcOp,
int64_t  index,
const BufferizationOptions options 

Return the index-th bufferized function argument type.

This assumes that the specified argument is a tensor. If the tensor is ranked, a layout map may be specified by the user. If no layout map is specified, the default layout map (as per options.functionBoundaryTypeConversion) is used.
