MLIR Program:
```mlir
module {
func.func @m0(%arg0: memref<4xf32>) -> () {
%cst_1 = arith.constant 0.000000e+00 : f32
%36 = vector.constant_mask [8] : vector<8xi1>
%cst_12 = arith.constant 0.000000e+00 : f32
%37 = vector.broadcast %cst_12 : f32 to vector<8xf32>
%38 = vector.mask %36 { vector.multi_reduction <add>, %37, %cst_12 [0] : vector<8xf32> to f32 } : vector<8xi1> -> f32
%39 = arith.addf %38, %cst_12 : f32
return
}
func.func @m47(%arg0: tensor<4xf32>) -> () {
%send = shard.send %arg0 on @m64 destination = [] : (tensor<4xf32>) -> tensor<4xf32>
return
}
shard.grid @m64(shape = 2)
}
```
Reproduce Command: `mlir-opt --convert-shard-to-mpi a.mlir`
StackTrace:
```
a.mlir:12:13: error: failed to legalize operation 'shard.send' that was explicitly marked illegal: %0 = "shard.send"(%arg0) <{destination = array<i64>, grid = @m64, grid_axes = array<i16>}> : (tensor<4xf32>) -> tensor<4xf32>
%send = shard.send %arg0 on @m64 destination = [] : (tensor<4xf32>) -> tensor<4xf32>
^
a.mlir:12:13: note: see current operation: %0 = "shard.send"(%arg0) <{destination = array<i64>, grid = @m64, grid_axes = array<i16>}> : (tensor<4xf32>) -> tensor<4xf32>
