> Instead of filtering it out here, how about checking for `__LD,__compact_unwind` inside `createOutputSections()` while looping over `mergedOutputSections`, and then doing something like `unwindInfoSection->setCompactUnwind(...)`? Benefits: no need for the loop in `UnwindInfoSection::isNeeded()`, no need for `getOutputSection`, and no need to create an outputSegment to be discarded later.

No followup necessary. I did it all here.
