[PATCH] D60042: [llvm-objcopy] Add --prefix-alloc-sections

[Seiya Nuta via Phabricator via llvm-commits]

seiya updated this revision to Diff 196167.
seiya added a comment.

- Use `dyn_cast`
- Add `PrefixedSections` to check whether the target section is already prefixed `AllocSectionsPrefix`.
- Handle the case when `--rename-section` and `--prefix-alloc-sections` are given and the relocation section comes //before// its target section.
