<br>
Rather by accident than on purpose I looked at the release notes and found the following:<br>
<a href="http://releases.llvm.org/8.0.0/docs/ReleaseNotes.html#changes-to-the-jit-apis" rel="noreferrer" target="_blank">http://releases.llvm.org/8.0.0/docs/ReleaseNotes.html#changes-to-the-jit-apis</a><br>
<br>
TL;DR: Orc v1 is deprecated and will be removed in the next release.<br>
<br>
I have several questions in this regard:<br>
<br>
1. Is there a migration guide I can use to update my code to the new version?<br>
2. Is there any development plan for this part of LLVM? So far I have feeling that it's a closed source development.<br>
3. Is there some communication channels I am missing to follow? I follow dev&commits mailing lists and present on IRC once in a while, but I somehow missed the message about the Orc v1 removal.<br>
<br>
Also, the release notes mention that Orc v2 is the recommended way for the new projects, but:<br>
<br>
1. Is there a documentation?<br>
2. How stable the APIs are?<br>
<br>
Thank you,<br>
Alex.<br>
