--- Comment #1 from Bas Nieuwenhuizen <bas at basnieuwenhuizen.nl> ---
I went looking to why there were no good CTS tests for this and found this in
the vulkan spec:

For the OpSRem and OpSMod instructions, if either operand is negative the
result is undefined.

Note
While the OpSRem and OpSMod instructions are supported by the Vulkan
environment, they require non-negative values and thus do not enable additional
functionality beyond what OpUMod provides.


While I'm open to fixing this, you may want to rethink what you are doing.
