Andrea,
Do we need libgccjit only for compiling to *.eln, or do we also need
it for loading and executing the *.eln files?
IOW, if Emacs was built with libgccjit, but the library isn't
available at run time, will Emacs still be able to load and run *.eln
files that were produced elsewhere (assuming the native code is
compatible with the platform where it will be run)?
Thanks.

We don't use libgccjit for loading elns file but we still have libgccjit
as a dependency because ATM Emacs may need to compile a trampoline if a
primitive is redefined or advised. If it's important to support native
builds with no libgccjit available we should redesign this specific
mechanism.

Andrea

I don't have any evidence that we need to support such builds, I guess
we will hear from downstream distro maintainers if they are needed.
Thanks.
