[PATCH] D96035: [WIP][dsymutil][DWARFlinker] implement separate multi-thread processing for compile units.

[David Blaikie via Phabricator via llvm-commits]

>> By "generating resulting DWARF" I guess that has to be buffered in memory? (how could two CUs be written to the final output file at the same time? You wouldn't know where to write to because you wouldn't know how big the previous unit would be if you haven't finished processing it)

That seems quite expensive :s

"how this implementation works" - the patch in this review? The existing checked-in implementation? (apologies as I'm not especially familiar with the implementation of dsymutil as it is today)
