<pre>
I have the following MLIR program:
test.mlir:
`mesh.mesh @mesh_2d(shape = 2x4)
func.func @element_wise_on_def(%arg0: tensor<8x16xf32>, %arg1: tensor<4096x14336xf32>) -> tensor<8x16xf32> {
%0 = tosa.sigmoid %arg0 : (tensor<8x16xf32>) -> tensor<8x16xf32>
%1 = mesh.shard %0 to <@mesh_2d, [[0], [1]]> : tensor<8x16xf32>
return %1 : tensor<8x16xf32>
}`
The program does not use %arg1,but when running the --pass-pipeline="builtin.module(func.func(sharding-propagation,cse))"
The correct result is as follows:
`module {
mesh.mesh @mesh_2d(shape = 2x4)
func.func @element_wise_on_def(%arg0: tensor<8x16xf32>, %arg1: tensor<4096x14336xf32>) -> tensor<8x16xf32> {
%sharding_annotated = mesh.shard %arg0 to <@mesh_2d, [[0], [1]]> annotate_for_users : tensor<8x16xf32>
%0 = tosa.sigmoid %sharding_annotated : (tensor<8x16xf32>) -> tensor<8x16xf32>
%sharding_annotated_0 = mesh.shard %0 to <@mesh_2d, [[0], [1]]> : tensor<8x16xf32>
return %sharding_annotated_0 : tensor<8x16xf32>
}
}`
The above MLIR program will cause a crash when using the following command:
`mlir-opt --pass-pipeline="builtin.module(func.func(mesh-spmdization,test-constant-fold))" test.mlir`
And the crash backtrace is:
`mlir-opt: mlir/lib/Dialect/Mesh/Transforms/Spmdization.cpp:536: mlir::mesh::shardedBlockArgumentTypes(mlir::Block&, mlir::SymbolTableCollection&)::<lambda(mlir::BlockArgument)>: Assertion `rankedTensorArg.hasOneUse()' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
