We're using only GEPs from start, so we might not hit all the problems you did.

I was actually surprised that the change to support those ABI
constraints wasn't too big...

Maybe even steeper than introducing new fields to the IR...

:D

One thing at a time... It's in my TODO list to prepare a document with
all the hacks one has to do to make C++ be translated to IR.

As far as I know, llvm-gcc and clang had the same problems and solved
the same hacky way, so there might be other people that would agree on
some more radical changes. But we need more evidence to start with...
One thing at a time... ;)
