Yeah, me too I wish I could remember what exactly the problem was now.

The comment put in at the time said that it was a problem with SFmode
floats, but i'm not sure what it was doing wrong with them :) I'll do a
quick test and if a regression doesn't show itself offhand with
mips64-elf I'll check it in.
