Well, the intrinsic calls could be explained by using call rather than tail call in the IR, but I really don't get why the fadd etc instructions aren't converted to tail calls. Does LegalizeFloatTypes just fail to mark its libcalls as tail call candidates?

I think the TargetLowering::makeLibCall used by LegalizeFloatTypes doesn't set the tail call bit.
