Here, a completely new and important concept is introduced into LLVM, and the patch description describes the new concept completely.

However, the relevant documentation is updated not at all.

The new field isn't even documented in the Target.td file.

The ONLY way to learn what isArtificial does, is to either read all these individual changes and understand their impacts, or to Google to find this particular change request.

Respectfully, this is no way to run a railroad.  Please be nice to the programmers of the future.
