qiucf added a comment.

Making a new option mapped to another float op flag looks reasonable, but is 
there any clearer motivation for this? (such as the need for `-Ofast 
-fno-approx-func`)

----------------
`-enable-no-signed-zeros-fp-math` is an `llc` flag.

Do we really have `-enable-approx-func-fp-math` for `llc` now?
