When looking at a perf profile of a link with objects with compressed debug info and `-S` in ldflags, I noticed that a substantial amount of time was spent in `MergeInputSection::splitIntoPieces` -> `InputSectionBase::decompress`. This seems to be because the code that implements section stripping operates on `ctx.inputSections` while `splitSections` operates on `ctx.objectFiles`.
