My git version is [55fdecc](https://github.com/llvm/llvm-project/commit/55fdeccc4567bcd4e3f8df0d177195880a194a6a).
## Description:
I am experiencing an inconsistent result when executing the same MLIR program with and without the `-tosa-test-quant-utils`.
## Steps to Reproduce:
### 1. **MLIR Program (test.mlir)**:
test.mlir:
```
module {
func.func private @printMemrefI32(tensor<*xi32>)
func.func @main() -> () {
%arg0 = "tosa.const"() {value = dense<-4636> : tensor<52x3x2xi64>} : () -> tensor<52x3x2xi64>
%0 = tosa.reduce_sum %arg0 {axis = 0 : i32} : (tensor<52x3x2xi64>) -> tensor<1x3x2xi64>
%1 = tosa.equal %0, %0 : (tensor<1x3x2xi64>, tensor<1x3x2xi64>) -> tensor<1x3x2xi1>
%2 = tosa.cast %1 : (tensor<1x3x2xi1>) -> tensor<1x3x2xi32>
%rtn2 = tensor.cast %2 : tensor<1x3x2xi32> to tensor<*xi32>
call @printMemrefI32(%rtn2) : (tensor<*xi32>) -> ()
return
}
}
```
### 2. **Command to Run Without `-tosa-test-quant-utils`:**
```
/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 -convert-cf-to-llvm -convert-arith-to-llvm -finalize-memref-to-llvm -convert-func-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 `-tosa-test-quant-utils`:**
```
[[[1, 1],
[1, 1],
[1, 1]]]
```
### 4. **Command to Run With `-tosa-test-quant-utils`:**
```
/path/llvm-project/build/bin/mlir-opt test.mlir -tosa-test-quant-utils | \
/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 -convert-cf-to-llvm -convert-arith-to-llvm -finalize-memref-to-llvm -convert-func-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 `-tosa-test-quant-utils`:**
```
[[[-1, -1],
[-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.
