Print a scalar

Using graphblas.print

%0 = graphblas.equal %a, %b : tensor<?x?xf64, #CSR64>, tensor<?x?xf64, #CSR64>
graphblas.print %0 { strings=["is_equal: "] } : i1

Print a Sparse Tensor

Using vector.print
%m is a 7x10 matrix with 12 values

%c0 = constant 0 : index
%c1 = constant 1 : index
%cf0 = constant 0.0 : f64
%ci0 = constant 0 : i64
%ptrz = sparse_tensor.pointers %m, %c1 : tensor<?x?xf64, #CSR64> to memref<?xi64>
%idxz = sparse_tensor.indices %m, %c1 : tensor<?x?xf64, #CSR64> to memref<?xi64>
%valz = sparse_tensor.values %m : tensor<?x?xf64, #CSR64> to memref<?xf64>
%ptrz_vv = vector.transfer_read %ptrz[%c0], %ci0: memref<?xi64>, vector<8xi64>
%idxz_vv = vector.transfer_read %idxz[%c0], %ci0: memref<?xi64>, vector<12xi64>
%valz_vv = vector.transfer_read %valz[%c0], %cf0: memref<?xf64>, vector<12xf64>
vector.print %ptrz_vv : vector<8xi64>
vector.print %idxz_vv : vector<12xi64>
vector.print %valz_vv : vector<12xf64>

Print in C++ lowering pass

Using graphblas.print

rewriter.create<graphblas::PrintOp>(loc, val, rewriter.getStrArrayAttr({"val="}));

rewriter.create<graphblas::PrintOp>(
    loc,
    ValueRange{loopIdx, a, b, c},
    rewriter.getStrArrayAttr({"loopIdx=", "a=", "b=", "c="})
);
