[PATCH] D33824: [ELF] - Do not merge relocation sections by name when using --emit-relocs.

[George Rimar via Phabricator via llvm-commits]

grimar created this revision.
Herald added a subscriber: emaste.

Previously we would merge relocation sections by name.
That did not work in some cases, like testcase shows.

Patch implements logic to merge relocation sections if their target
sections were merged into the same output section.

Such approach should allow to implement linker script case (https://reviews.llvm.org/D33780) in a
simple way.

Testcase and idea to change how we handle this belongs to Rafael Espíndola.
