No it isn't.
The IR is being changed, but the changes are not revolution, they are
evolution, as you put it.

This is not some major data structure change, it involves changing some
enums and macro names, and changing the functions as appropriate for
new semantics.

Of course, i'm summarizing a large amount of code (I work on the branch
in question every day :P) in one sentence, so someone may take issue
with it.
But in terms of "how deep it goes", this is as fundamental as the
changes GDB needs in the areas i mentioned.
No more, no less.

It may seem more fundamental to someone who doesn't work on the
internals of compilers, but trust me, it's not.
