[PATCH] D72194: [MC][ELF] Ensure that mergeable globals with an explicit section are assigned to SHF_MERGE sections with compatible entsizes

[ben via Phabricator via llvm-commits]

bd1976llvm updated this revision to Diff 256011.
bd1976llvm added a comment.

- Removed Clang parts of the diff. Error behaviour from llc and clang is still acceptable without the Clang parts. A generic "error: <reason>" is issued rather than a "backend" or "lowering" error as we had before... but the message contents should still allow for easy diagnosis. I will put up the Clang parts as a separate diff.
- Rebased the patch.
