As discussed in the thread "HEADS UP: Don't upgrade your Alphas!", I would like to make the -mieee option to gcc the default, since lots of floating point stuff breaks without it. Alpha hardware doesn't support IEEE FP, so there is a performance penalty associated with this; when a floating point value x *might* be NaN, the compiler inserts explicit logic to generate a trap only if appropriate. (It seems to use cmpt??/su most of the time). I just wanted to check if there were any objections before moving forward.
