--- Comment #3 from Aaron Ballman <aaron at aaronballman dot com> --- (In reply to Andrew Pinski from comment #1) > I don't think it should be deprecated or removed. It still has its uses. Can you explain what those uses are and why they're not served by a more explicit command line with `-O3 -ffast-math`? Mostly trying to understand if there's something we've missed with Clang's assessment. > Documentation is clear too. > > We just fixed some documentation about the flags being enabled by -Ofast too. > > People will never read the documentation either way anyways. Agreed, that's part of why we're deprecating.
