[PATCH] D47799: [COFF] add /errorrepro to save reproducer on error

[Peter Collingbourne via Phabricator via llvm-commits]

pcc added a comment.

> As I pointed out earlier, /linkrepro isn't really what I would want for that because you either need to re-run the link until you hit the same failure again, which could be very time consuming, or pre-emptively run with /linkrepro, which slows down links and writes lots of bytes you usually don't care about.

You could always rerun the link with /linkrepro if the link fails. Even if the second link succeeds, you still have a reproducer that you can try repeatedly until you hit the failure.
