[M3devel] [M3commit] CVS Update: cm3

[Tony Hosking]

Note that the front-end refuses to do any constant folding that results in overflow.  Instead, it generates code that will execute at run-time.  If that causes a run-time error then fine.  Similarly, the back-end should never do constant folding for things that overflow.
