Thanks.  I've fixed this and cleaned up a bit the div / floordiv /
truediv mess that we have in low-level operations.  Now there is only
'int_floordiv' (and uint_floordiv, llong_floordiv...) for integer types,
and 'float_truediv' for floats.  In the example you give, the RTyper now
introduces conversions from int to float of both x and y before using
'float_truediv'.  (Interestingly, this is done by removing all
references to 'truediv' from IntegerRepr and letting it fall back to its
superclass FloatRepr.)

A bientot,
