Build issues related to Intrinsics for _clri, _enable while building with ARC GNU toolchain

[srikantw]

I'm getting below build issue while building my code with ARC GNU compiler toolchain.

error: '_clri' was not declared in this scope
  546 |         status = _clri();

 error: '_enable' was not declared in this scope; did you mean 'enable'?
  968 |        _enable();

Can anyone suggest the intrinsics required for the above in order to resolve the build issues?

Thanks.
