[PATCH] D67656: [llvm-objcopy] Add --set-section-alignment

[Fangrui Song via Phabricator via llvm-commits]

MaskRay added a comment.

binutils commit fa463e9fc644e7a3bad39aa73bf6be72ea865805 (2019-08-28) implemented --set-section-alignment.

- Its interaction with --rename-section is unclear. We disallow the combination of --rename-section + --set-section-flags because both options can specify the flags. --set-section-alignment does not have the conflict.
- In GNU objcopy, `--set-section-alignment .data=8` specifies the exponent for the power of two, so this sets the alignment to 256. I think this a strange behavior.
