[PATCH] D102634: Calculate indexes of last child of each DWARF entry once during tryExtractDIEsIfNeeded.

[Simon Giesecke via Phabricator via llvm-commits]

simon.giesecke added a comment.

One thing I don't know here is whether all relevant uses of `DWARFUnit` will end up iterating the children. If that's not the case, then this be done only optionally. We can't do it on-demand on the first call to getLastChild easily though, because then, e.g. GsymCreator, would need to synchronize accesses from multiple threads. But maybe this could be passed as an option to `tryExtractDIEsIfNeeded`?

If this is worthwhile, a similar thing could be done for the siblings.
