integer and floating-point storage
...to 254 so that 1 and 2 could be represented with
perfect precision as 127/127 and 254/127 (but I would do regression on the
integer values). Or I could use 16 bits, doubling memory load and
improving precision. It would be convenient if R could work with
half-precision floating-point numbers (binary16):

Can R do that?
If not, is anyone interested in working on developing some of these
features in R? We have GPL code from PLINK and Octave that might help a
lot.

Implementing a proposed InstCombine optimization
> I am not entirely sure this is safe. Transforming this to an fsub could change the value stored on platforms that implement negates using arithmetic instead of with bitmath (such as ours)
I think it's probably safe for IEEE754-2008 conformant platforms because negation was clarified to be a non-arithmetic bit flip that cannot cause exceptions in that specification. However, I'm sure
