[llvm] r223113 - Add support for ARM modified-immediate assembly syntax.

[Steven Wu]

Hi Asiri

Have you had a chance to look at this problem yet? Since the immediates are evaluated as int64_t, I cannot see an easy way to fix this. I don’t think we can allow a false positive for this error message either. Do you have any solution?

Thanks

Steven
