llvm dev - Jun 2014 - [LLVMdev] Why llvm-pass don't work when applied on itself(passfile)

Hi,
I applied some pass i.e.  Hello pass on Hello.cpp(the pass file).It doesnot
work as using command clang -emit-llvm -c Hello.c(Hell.cpp) does not create
any .bc file .Can any body have some suggestion ?

Thanks

Is the problem that you can't create a bitcode file or that you can't 
get clang to run your pass?

Assuming you can't generate a bitcode file, clang -emit-llvm -c
<file.c>
should create a file ending with .o that is an LLVM bitcode file.  It 
will not have a .bc suffix.

Let's take Hello.cpp  pass file from llvm/lib/Transform/Hello. Now I want
to run clang -emit-llvm -c Hello.cpp(Hello.c).Means I want to apply this
pass on itself.Then there are too many errors.
