    LLVM 2.2 was the last LLVM release to support llvm-gcc 4.0 and llvm-upgrade. -llvm-gcc 4.0 has been replaced with llvm-gcc 4.2. llvm-upgrade was useful for -upgrading LLVM 1.9 files to LLVM 2.x syntax, but you can always use a previous -LLVM release to do this. One nice impact of this is that the LLVM regressionn -test suite no longer depends on llvm-upgrade, which makes it run faster.
