Hi Simon,
> We need to keep to this basic pattern to ensure we spill a lot to stack and the 'big vectors' approach drastically helps makes this simple to understand. Using a more basic load/cvt/store pattern would mean that it wouldn't be the memory folding code thats being tested - the load-execute version of the instruction from the tables would be matched much earlier instead.
I was afraid of that. Could you add a comment explaining that at the being of the tests?
Please commit with this change.
Thanks,
-Quentin
