    #### Problem Description:
When running the following command to optimize `OPT.ll` by adding O3 optimization:

```sh
opt -opaque-pointers -O3 -S -o OPT_O3.ll OPT.ll 
```

an error occurs indicating an unterminated attribute group:

```
opt: OPT.ll:156495:57: error: unterminated attribute group
attributes #0 = { nocallback nofree nounwind willreturn memory(argmem: readwrite) }
 ^
```
 #### Cause:
The error arises from line 156495 of `OPT.ll`, where an attribute group is not properly terminated or formatted according to LLVM IR syntax.
 
I have attached the OPT.ll file to reproduce the error by running the above mentioned command.
