LGTM, though I will say that ideally this wouldn't accept a Call at all. it looks like the two uses are the function to get the vscale range and OptimizeConstMinMax to get FMF. FMF should really be passed in as an explicit argument, and I guess at that point one would replace the call arg with a function arg.
