Correctly-rounded FMA came up recently as an ingredient in double-double. Of course the followup question is, does double-double matter? And until I read that article I had been under the impression (since the 1990s!) that double-double is probably too expensive to be worthwhile. But iin fact t’s cheaper than software f128!

Curious why it was surprising that the musl folks took the report seriously.
I didn't see mention of reporting it to FreeBSD. Given the above it seems like that might be a good idea too.

Fun tangentially related fact: there's a (extremely) nascent proposal to add Math.fma to JavaScript.
