If you're using the clang executable, it does automatic inlining as
long as you turn on the optimizers.  You can tweak how aggressive the
inliner is with the -inline-threshold command-line parameter; the
default value is 200.

If you're writing your own program using the clang libraries, you'll
have to invoke the inliner yourself; http://llvm.org/docs/ would be
helpful for that.

That said, what are you planning to do with clang?  We're always
interested in hearing about new users.
