[PATCH] D58762: [BinaryFormat] Add DT_USED tag into dynamic section.

[James Henderson via Phabricator via llvm-commits]

jhenderson added a comment.

Hmmm... I'm not sure about this. The code and test look fine, but I'm wondering if we should even support this? (I have similar concerns re. DT_AUXILIARY and DT_FILTER by the way, but they're already recognised by LLVM). In particular, this is in the processor-specific tag range, so could conflict with the value some developers have used for their own processor-specific tag. Some questions before I give this the thumbs up:

1. Do GNU objdump and readelf recognise this flag?
2. Do you know of any actual users of this tag?
3. Is there documentation for these tags anywhere other than the Oracle/Sun documentation? I'm not talking about code examples here by the way.
