Comment (by carter):

 Ben: what are your current thoughts about how to handle supporting
 different microarchitectures?

 1) Allow generating the instructions but require the application to do cpu
 detection to avoid bad instructions ? (I’d be fine with that )

 Or

 2) add micro architecture logic to ghc compilation and have a fall back
 path?


 Or

 3) some mix of both supported?


 I’d think near term 1 would be simpler to get working and 3 is what we
 want to love to
