I don't know of any GCC plugin within the GCC code base (except the test cases for plugins).

And I am not sure it would be that easy. If I understand well,
what you suggest would either fill some gcc_jit_context, or create it already filled with an API.

But, AFAIK, there is no current way to query the content of some gcc_jit_context. In other words, it
seems (but I could be wrong) that what is lacking is an API to e.g. *fetch* all the struct-ures and
all the functions inside a gcc_jit_context, and we don't have that yet.

Or perhaps, I have misundertood your idea.

My feeling was that the GCC plugin would fill whatever data structure is used by the application using libgccjit.
And that is application specific -so the GCC plugin has to be application specific too.

Cheers

PS. I could be very wrong, it is not clear in my head!
