My git version is [9d7ca6c](https://github.com/llvm/llvm-project/commit/9d7ca6cdf038dab24fbc5c22a91be36604decb67).
## Description:
I am experiencing an inconsistent result when executing the same MLIR program with and without the `-test-math-to-vcix`.
## Steps to Reproduce:
### 1. **MLIR Program (test.mlir)**:
test.mlir:
```
module {
func.func private @printMemrefI32(tensor<*xi32>)
func.func @main() {
%0 = "tosa.const"() <{values = dense<-16> : tensor<4x1xi32>}> : () -> tensor<4x1xi32>
%1 = tosa.equal %0, %0 : (tensor<4x1xi32>, tensor<4x1xi32>) -> tensor<4x1xi1>
%2 = tosa.cast %1 : (tensor<4x1xi1>) -> tensor<4x1xi32>
%cast = tensor.cast %2 : tensor<4x1xi32> to tensor<*xi32>
call @printMemrefI32(%cast) : (tensor<*xi32>) -> ()
return
}
}
```
### 2. **Command to Run Without `-test-math-to-vcix`:**
```
/path/llvm-project/build/bin/mlir-opt test.mlir -pass-pipeline='builtin.module(func.func(tosa-to-linalg))' | \
/path/llvm-project/build/bin/mlir-opt -tosa-to-tensor -tosa-to-arith -one-shot-bufferize="bufferize-function-boundaries" -convert-linalg-to-affine-loops -lower-affine -convert-scf-to-cf -expand-strided-metadata -lower-host-to-llvm -convert-cf-to-llvm -reconcile-unrealized-casts | \
/path/llvm-project/build/bin/mlir-runner -e main -entry-point-result=void \
-shared-libs=/path/llvm-project/build/lib/libmlir_runner_utils.so \
-shared-libs=/path/llvm-project/build/lib/libmlir_c_runner_utils.so \
-shared-libs=/path/llvm-project/build/lib/libmlir_async_runtime.so
```
### 3. **Output Without `-test-math-to-vcix`:**
```
[[1],
[1],
[1],
[1]]
```
### 4. **Command to Run With `-test-math-to-vcix`:**
```
/path/llvm-project/build/bin/mlir-opt test.mlir -test-math-to-vcix | \
/path/llvm-project/build/bin/mlir-opt -pass-pipeline='builtin.module(func.func(tosa-to-linalg))' | \
/path/llvm-project/build/bin/mlir-opt -tosa-to-tensor -tosa-to-arith -one-shot-bufferize="bufferize-function-boundaries" -convert-linalg-to-affine-loops -lower-affine -convert-scf-to-cf -expand-strided-metadata -lower-host-to-llvm -convert-cf-to-llvm -reconcile-unrealized-casts | \
/path/llvm-project/build/bin/mlir-runner -e main -entry-point-result=void \
-shared-libs=/path/llvm-project/build/lib/libmlir_runner_utils.so \
-shared-libs=/path/llvm-project/build/lib/libmlir_c_runner_utils.so \
-shared-libs=/path/llvm-project/build/lib/libmlir_async_runtime.so
```
### 5. **Output With `-test-math-to-vcix`:**
```
[[-1],
[-1],
[-1],
[-1]]
```
I'm not sure if there is any bug in my program or if the wrong usage of the above passes caused this result.
