Preprocessor define for when code is being compiled for compute?

[jkant]

Is there a preprocessor define enabled for when the code is being compiled for compute vs. the normal CPU compiler?

I would like to be able to re-use as much code as I can, but the HLSL intrinsics don't do anything on the CPU side, whereas the System.Math equivalents won't work on the GPU. I would prefer to write a wrapper function around the couple of intrinsics I am using that conditionally points to the appropriate function, rather than maintain parallel versions of all the code that uses these intrinsics.

Thanks!

As an alternative, it would be great if we could map certain C# functions to their HLSL equivalents. For example -

float.Lerp, float.Max, float.Pow, float.Log

I don't think this should be terribly difficult and I'd be interested in contributing but not sure where to start looking on the codebase so figured I would add this as a comment here in case somebody else can get to it first.
