Intrinsics.gen file not found

For some reason, this morning the Intrinsics.gen file is not being generated. I did a update-checkout and rebuilt the xcode project and no luck. Attaching a screen shot..

Anybody know how to resolve this?

Sounds like you are just rebuilding swift, not LLVM. If you run build-script with -x and get through the LLVM part of the build I think it will work.


I did that running all night last night and woke up with a Build Succeded mesasge this morning. Do you think I need a clean rebuild?

That couldn't hurt.
