            Bug ID: 23711
           Summary: Add a way to omit code generation
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Driver
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

In particular while refactoring, I modify the code, compile, modify code,
compile, ... until the compiler has caught all my errors. I then start running
my tests: modify, compile, test, modify, ...

In the first phase of refactoring, I am not really interested in code
generation. I just want clang to check that my source code is valid C++. 

I expect the LLVM code generation to be expensive. It would be nice if there
was an option to avoid it in those situations in which the programmer is not
interested in generating any code. 

It might speed up the first phase of refactoring C++ code significantly.
