We recently introduced a new option "-ffp-model=[precise|fast|strict], which is supposed to serve as an umbrella option for the most common combination of options. I think our default behavior should be equivalent to -ffp-model=precise, which enables contraction. It currently seems to enable -ffp-contract=fast in the precise model (https://godbolt.org/z/c6w8mJ). I'm not sure that's what it should be doing, but whatever the precise model does should be our default.
