39 Here we describe how to write the "hello world" of passes.  The "Hello" pass is
43 source tree in the ``lib/Transforms/Hello`` directory.
55 we'll assume that you made ``lib/Transforms/Hello``.  Finally, you must set up
67     LIBRARYNAME = Hello
78 ``$(LEVEL)/Debug+Asserts/lib/Hello.so`` that can be dynamically loaded by the
132   struct Hello : public FunctionPass {
134 This declares a "``Hello``" class that is a subclass of :ref:`FunctionPass
142     Hello() : FunctionPass(ID) {}
150         errs() << "Hello: ";
154     }; // end of struct Hello
164   char Hello::ID = 0;
171   static RegisterPass<Hello> X("hello", "Hello World Pass",
176 ``Hello``, giving it a command line argument "``hello``", and a name "Hello
193       struct Hello : public FunctionPass {
195         Hello() : FunctionPass(ID) {}
198           errs() << "Hello: ";
205     char Hello::ID = 0;
206     static RegisterPass<Hello> X("hello", "Hello World Pass", false, false);
