Issue deprecation warning on startup.

[ducky64]

Does it make sense to print the error at the end of elaboration? Printing it at the start could just mean that it immediately gets pushed off the screen by a wall of text generated during elaboration?

If you have access to the millennium machines, you can check the console output from bare-chisel build 512.

Yeah that definitely looks good.

Appears to both print at the end of elaborate

Right. We could easily suppress the printing at the end of the test run, but the argument you raised earlier (the warning may scroll off the screen given sufficient output) would apply here as well. Suppressing the warning after elaboration iff we know testing will follow seemed an unwarranted complication: since we want to discourage usage, erring on the side of too many warnings seems quite appropriate.

I don't think suppression is a good idea, I posted the two examples there for those who do not have access to the build outputs.

We're in violent agreement.
