[Vm-dev] CompiledMethod header bits index 29 (flag bit)

What is the intention of the flag bit in the CompiledMethod header?

Just interested what it is good for, or was used for originally.
More specifically, I would like to verify that I can just reuse it without having to worry about to many incompatibilities.

My understanding so far is that it is only used to highlight methods in a browser.


PS: the split encoding of the primitive code seems also to be a beautiful artifact of an old legacy ;)
