No, you can still link those. There's no ABI change nor any interference at IR level. Thanks for the pointer, I wasn't aware of that option. What we can do is to optimize away the freezes with -ffine-grained-bitfield-accesses. The freeze is only needed when a struct field is shared between more than one bitfield. Regarding perf, it's looking good, but @jmciver will post here a summary later.
