24/// \file
25/// Some thin wrappers around the Clang/LLVM API used to preserve
26/// compatibility with older API versions while keeping the ifdef clutter low
27/// in the rest of the clover::llvm subtree.  In case of an API break please
28/// consider whether it's possible to preserve backwards compatibility by
29/// introducing a new one-liner inline function or typedef here under the
30/// compat namespace in order to keep the running code free from preprocessor
31/// conditionals.
