- Currently, LLVM supports symbols of the name "token1@token2".
- "token2" is used to identify whether an appropriate symbol reference can be used for the symbol.
- Now, if the symbol reference couldn't be found, the AsmParser usually emits an error, unless the backend is configured to accept the "@" in a symbol name
- Thus, this patch aims to do that. It sets the `AllowAtInName` attribute in the SystemZ backend for the HLASM dialect.
- Setting this attribute ensures that, if a particular symbol reference is found, it uses that. If it doesn't, and there exists an "@" in the symbol name, it will use that instead of explicitly erroring out.
