[cfe-dev] enabling CodeGen options before Pass is ran?

[ret val]

Is there anyway for me to set a option for CodeGen(
CodeGenOptions::EmitDeclMetadata<http://clang.llvm.org/doxygen/classclang_1_1CodeGenOptions.html#a65c32a27e41ceb9465c6ee27fdac4c9a>)
before my Pass is ran? I'm guessing time my Pass is actually running its too
late. I don't understand the consequences of running CodeGen a second, is
this a possibility or is there a better approach.

Thank you
