[cfe-dev] Passing arguments to a custom clang pass

[Santosh Nagarakatte]

Thanks, thats helpful.

Also, I want to pass an extra argument to my pass as shown below.
clang -my_rewriter -my_rewriter_option foo.c

I think I don't need to do most of the modifications you suggested for
-my_rewriter_option and those are required only for -my_rewriter.

Any suggestions, Am I wrong?

Thanks,
Santosh
