Do you recall when that was? Must have been long, long ago... I've tried to find where it happened, and the rewrite was done before at least r43893 (Tue Jul 10 10:38:10 2001 UTC (11 years, 9 months ago). Does that mean alpha ev4 and ev5 fp exceptions have been broken for maybe 12 years? If that's really the case then I'd say the proper way forward is to remove support for those alpha variants as they're obviously not used and/or tested by anyone...
