@theRealAph Thanks for clarification.

I think there are several different parts involved in the above discussion, 
please kindly correct me if I misunderstood.
1. package builders. This is about the release of jdk (both src and binary), by 
either openjdk, adoptium, or any other downstream vendors.
2. jdk daily development. This is about to modify, build, run/test jdk daily by 
jdk developers.

For the package builders, original sleef source is necessary; for the jdk daily 
development, only pre-generated sleef inline headers are necessary. The script 
to pre-generate sleef inline headers is only triggerred by package builders 
(and I think it involves some scripts which are not part of jdk source ? e.g. 
the script to trigger pre-generating script), but for jdk daily development, we 
just need pre-generated sleef inline headers.
Am I understanding correctly above?
