How is this "backwards compatible"?
If someone takes a new LLVM and tries to load those programs
into an older kernel they will be rejected.
There appears to be no effort to make things work cleanly in
that situation at all.
No, that was just the patch I used for LLVM to enable the
insns, so not the final one that will be submitted there
officially where we have a switch to enable/disable this
functionality.
