            Bug ID: 34997
           Summary: clang-cl: /showIncludes doesn't work with /EP
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P

/P /EP foo.cc /Fiout.ii /showIncludes 
clang: warning: argument unused during compilation: '--show-includes'

Works fine if I use just /P:

/P foo.cc /Fiout.ii /showIncludes 
Note: including file:

But I want preprocessor output without line directives. Is there a reason why
this doesn't work, or is it just an oversight?
