[PATCH] D78208: [DebugInfo] Report the format of the DWARF64 sections.

[James Henderson via Phabricator via llvm-commits]

jhenderson added a comment.

So, given we're going to start emitting DWARF64 stuff, unless it is going to be forevermore opt-in only (it won't...), I do think my earlier point stands, that people need to expect that output will sometimes change, if it means producing more useful output. In this case too, if the output might suddenly change and break their scripts, just because their debug data has grown a few bytes bigger, it might be very confusing. I think we should just bite the bullet, make the output format change for DWARF32 too, and document the change in behaviour in a release note. Yes, it will break things, but better that people are aware why there's a sudden breakage rather than one appearing in 5 years time when their DWARF grows a bit too big.
