I am still confused with WordArray in Pharo terminology: 32bit or native 
register size?

For the naming I like the Java convention: byte(8), short(16), int(32), 
long(64).
Ideally that would make: ByteArray(8), ShortArray(16), IntegerArray(32), 
LongArray(64), WordArray(native), DoubleWordArray(native*2)

As for floats, one arithmetic on 64bit double is fine, but I think we need both 
32bit & 64bit loads/stores, that is having FloatArray(32) and DoubleArray(64). 
That would make UFFI code consistent among 32bit & 64bit machines . Also in x86 
all architectures do IEEE 64bit double arithmetic, so no need for a "native" 
register size.
