However, if you're reading garbage memory, you might get a denorm.
This is what we were suggesting in this case.

If a number can't be normalized, it is expressed by a denorm, which
does not have an implied 1 bit. The alpha neither generates nor
consumes denorms unless you specify the -mieee flag and pay a big
penalty.
