[LLVMdev] Question about analysis at compile time

[Jeffrey Bickford]

Hello,

I am currently working on a project that requires me to do some
analysis on code as it compiles.  I would like to print out all type
definitions for a kernel while it is compiling.  I can successfully
compile a kernel using llvm-gcc. I have been looking into writing a
pass to do this but do not know how to run a pass at compile time.  Is
there any tool already available to do this?  

Someone mentioned to me in the irc channel that I can add a pass to the
llvm-gcc source code.  Would anyone know specifically what files I
would need to edit and look through?  Thank you for any help.
