[cfe-dev] Integrating a pass as a clang option

[Jose Luis Vázquez via cfe-dev]

Good afternoon

I've developed a pass that I want to run directly from a clang 
invocation by setting an option in the command line. The pass has been 
ran through opt and tested for correctness. I've defined the option and 
the driver can parse it but I haven't been able to trigger the execution 
of the pass by the pass manager. Is there any particular structure I 
need to follow to convert the flag I added in 
include/clang/Driver/Options.td into an option parsed by the frontend?

Kindest regards

Jose Luis
