[PATCH] D59335: [RFC] Enable vectorization on Neon even without fast-math

[Renato Golin via Phabricator via llvm-commits]

rengolin added a comment.

I'm curious as to how will we generate these flags.

Is this the responsibility of the front-end, based on command line options, language standards, target-specific?

Or can some middle-end passes change that, too?

How do they propagate, and how does it merge with other fast-math flags?

I could not find a discussion about this on the list, it would be good to solve those before just adding another flag, especially when we already ran out of space. :)
