It appears that float support is complete, or at least, the stackmap records emitted are not inconceivable (I must admit that I don't know about many of the architectures under test here). One curiosity, the SystemZ tests highlight an undocumented (or maybe incorrect) quirk of the stackmap format: in the case of a Register record, the Offset or SmallConstant field can encode a sub-register index! I've only ever seen this field zero for Register entries up until now.
