[PATCH] D84131: [ELF] Support -r --gc-sections

[Peter Smith via Phabricator via llvm-commits]

psmith added a comment.

I guess if the use case for -r is a kernel module then garbage collection can make sense as the "object" is not relinked. What happens when there is no GC root? I think it will be worth detecting that and turning GC off as otherwise everything will get removed which is unlikely to be what was wanted.
