On MachO platforms that use subsections-via-symbols dead code stripping will drop prefix data. Unfortunately there is no great way to convey the relationship between a function and its prefix data to the linker. We are forced to use a bit of a hack: we give the prefix data it’s own symbol, and mark the actual function entry an .alt_entry. Patch by Moritz Angermann!
