I was exploring the idea to replace the bytecode backeend of a runtime
like by example JRuby
to construct a graph of graal's node.
So please correct me if I'm wrong but I think it's not possible currently
or possible in a very restricted way because each method need to be have
a bytecode attached.
By example, a deoptimize node will call a code in Hotspot that will
trigger the interpreter
so each method need a bytecode view.
Another related problem is that there is currently no node that does
I can't generate a graph of nodes with profile information that I will
be able to extract
using Graal interface with Hotspot.
