CLOC 1.0.14 gives wrong answer on OpenCL builtin log function with -noshared options

[PXAHyLee]

Hi developers,

The OpenCL log function gives wrong answer when the kernel code is compiled with -noshared option. The example seems to work when I use CLOC version 1.0.10.

How to reproduce: Use different CLOC compiler version with or without -noshared flag

Expected output:
[Use CLOC 1.0.10. compiler option: cloc.sh vector_copy_codeobject.cl]

Using <Carrizo>
found device region, flags=3
in[i]: 1.0000000. log(in[i]): 0.0000000. out[i]: 0.0000000
in[i]: 2.0000000. log(in[i]): 0.6931472. out[i]: 0.6931472
in[i]: 3.0000000. log(in[i]): 1.0986123. out[i]: 1.0986123
in[i]: 4.0000000. log(in[i]): 1.3862944. out[i]: 1.3862944

A log-testcase.tar.gz which I modified from vector_copy_codeobject_rocm is attached.

I haven't tested other builtin math function like sqrt used in my own kernel. I'll update the issue if I find there is a bug in other builtin math function.

Thanks,
