          Yeah, I'm frequently confused between `inverse` and `reverse` too. I think both names are correct descriptions of what they do, but maybe later we can come up with alternate names that are less confusing. Maybe "negate" instead of "inverse", and "swap" instead of "reverse", for example.

Name bikeshedding:

• negate or complement
• swapped or flipped

fitzgen commented on issue #6093:

Soft preference for flipped over swapped.

No preference on negate vs complement.

If there's an agreement on a set of names I can implement this change.

jameysharp commented on issue #6093:

Sounds good! It's not important to pick the perfect names for this so I'm not going to bother looking for agreement from everybody. We just need names that are better than what we have now. :laughing:

Let's go with Nick's preference for "flip" to replace "reverse" since nobody else spoke up, and I'll pick "negate" to replace "inverse".

I think we should pick the verb form of these words, so use "flip" because that is the thing the function does, rather than "flipped" as the thing the function returns.

Sorry for missing this issue, somehow I didn't see the notification and only saw this after #6862 above -- I do have some thoughts on the bikeshed color if it's not too late though!

flip and negate are both still very confusing to me: flip could mean that we're flipping arguments, or the sense of the condcode itself; and negate sounds like it has something to do with twos-complement negation.

I might suggest flip_args for the first -- that makes it very clear that this is the condcode for the case where the args are flipped (commuted).

I might suggest complement rather than negate as there's precedent in Boolean logic: a complement really is the opposite-bit result (true for false and vice-versa), without connotations of integer negation.

Thoughts?

After discussion in today's Cranelift meeting, our consensus is swap_args and complement. I'm sorry we didn't actually have consensus before you put a PR together!

No worries @jameysharp. I'll make the change.
