What does Java do? For Go, like Java, we should turn on the -mieee option by default. Both Go and Java specify the floating point model precisely--Go not as precisely as Java, but it does require denormals to be supported. Unfortunately I'm not sure how to do that. My best idea at the moment is to add a new target hook to common/common-target.def meaning "we actually care about floating point." That said, it would be easy enough to handle -mieee to way we handle -minline-all-stringops in libgo/configure.ac and libgo/Makefile.am. That would let us use -mieee when building and testing libgo. But it should really be the default in all cases, not just libgo. Ian
