Well, I can (and, even with my LLVM committer hat on, do) blame LLVM for =
not having a sensible deprecation strategy.  Breaking the ABI is =
unavoidable in a C++ project (unless you invent an entire metalanguage =
on top of C++, as Qt does) but breaking the API is a huge pain, when it =
would be no more effort in most cases to stick on a deprecation =
attribute telling people what they should be using instead.

Having llvm31, llvm32, and so on ports is likely to be unavoidable, as =
lots of external projects end up depending on older versions of LLVM.  =
It would be worth splitting out clang from these.  A few =
refactoring-type tools depend on old versions of clang, but most =
commonly people will be using latest clang with latest LLVM, plus =
something else with old LLVM. =20
