Will the new version of DCE allow to remove some portion of code depending on a boolean value? It could be interesting to have some debug/logging code but with no performance or code size impact in production. @bashor?

In IR it can be realized by custom compiler plugin

Yes, but it also makes sense to be part of the DCE:

if (false) {/* Dead code => remove */}

[bashor]

Yes, we are going to implement something like that, but not before we make IR BE default.

You can star or vote for KT-34912 to get updates.

(I think it should be a separate pass)

Also, we are thinking about the ability to provide some value externally. At least, it could be useful to able to distinguish debug/development and release/production builds, even we will not have a general solution.

Something like https://developer.android.com/studio/build/gradle-tips#share-custom-fields-and-resource-values-with-your-app-code?

It would definitively make sense to generate different variants of builds.
