That's a good question and I can't give you a full answer to that
because every time I look within the gcc internals I come away
thinking about how convoluted they are compared to LLVM.

Of course, the structure of the gcc internals are as much a political
decision as they are a technical decision.

I was about to post that DragonEgg was a long dead project (and it was),
but while checking, I came across this:

http://lists.llvm.org/pipermail/llvm-dev/2017-August/116705.html

so we now get to see if anything will become of this revival effort
or if DragonEgg will die once again.
