[PATCH] D75149: [ELF] --orphan-handling=: don't warn/error for unused synthesized sections

[Kees Cook via Phabricator via llvm-commits]

kees added a comment.

On my orphan checking kernel series, I'm left with only .rela_* and .rela.* getting reported, along with:

  (.shstrtab) is being placed in '.shstrtab'
  (.strtab) is being placed in '.strtab'
  (.symtab) is being placed in '.symtab'
