[PATCH] D46423: [WIP, RISCV] Support .option relax and .option norelax

[Lewis Revill via Phabricator via llvm-commits]

lewis-revill updated this revision to Diff 161497.
lewis-revill added a comment.

Apologies for the successive updates, however I have updated the revision to utilize an additional feature bit to implement the 'sticky bit' behaviour due to the concerns I mentioned in the previous comment. This revision requires more extensive tests and comments, however it appears to be functional.
