 Thanks applied,

I'm surprised that you did your regression tests longhand, rather than having
a data table in perl of input and expected output, and auto-generating parrot
code.

Is there any speed advantage in truncating by casting via a C type
[eg a = (int)(short) b]
rather than  and on a bitmask
[eg a = b & 0xFFFF]
?

We're going to have to do that latter to make it work on Crays anyway, so is
a conditional compile to chose between the two worth it?

The bitmask doesn't sign-extend where the casting will, which could be an issue.
