The flags that you used in your example don't exist:
```bash
$ bin/mlir-opt -tensor-reshape-propagation -linalg-elementwise-fusion -canonicalize  eample.mlir
mlir-opt: Unknown command line argument '-tensor-reshape-propagation'.  Try: 'bin/mlir-opt --help'
mlir-opt: Did you mean '--sharding-propagation'?
mlir-opt: Unknown command line argument '-linalg-elementwise-fusion'.  Try: 'bin/mlir-opt --help'
mlir-opt: Did you mean '--linalg-fuse-elementwise-ops'?
```

Where did you take them from? Also, the MLIR file is "broken":
```bash
$ bin/mlir-opt bad.mlir
bad.mlir:1:1: error: custom op 'func' is unknown (tried 'builtin.func' as well)
func @pad_fuse(%arg0: tensor<2x3xf32>) -> tensor<2x4xf32> {
^
```

There's more issues then just this one.

Please provide a working example first. Sharing broken examples is bad use of reviewers time.
