    I am not able to pass the OpenCL-CTS for `erfc` using [clvk](https://github.com/kept/clvk) on the following platform:
- Intel & AMD GPU on ChromeOS
- Nvidia (Tesla V100-SXM2-16GB) on Linux
- Swiftshader on Linux
- llvmpipe on Linux

I'm not sure if it's about `clvk` or if the implementation is not accurate enough.

Testing has been added to the OpenCL-CTS here:
https://github.com/KhronosGroup/OpenCL-CTS/commit/97cf4c7e25a72a835d315aaf82ffb9e32dfaedae

@kpet, @alan-baker, @frasercrmck, @karolherbst, is it passing on your side using libclc?
