 New conversion instructions:
  - Bitcast conversion between fp and ints. cast
- - Convert fp to/from int. convf convi (only signed at first, truncation)
- - Convert single to/from double convs convd
+ - Convert fp to/from int. ftosi sitof (only signed at first, truncation)
+ - Convert single to/from double stod dtos
 
 Summary:
-	Add bitcast, convf convi, convs convd
+	Add cast, ftosi sitof, stod dtos
 	Add a 'floating point' bit to instructions
+	Conversions from/to unsigned types are hard!
+	I need to find a reference for that.
