Comment at: clang/test/Driver/cl-options.c:567
-// This test was super sneaky: "/Z7" means "line-tables", but "-gdwarf" occurs
-// later on the command line, so it should win. Interestingly the cc1 arguments
-// came out right, but had wrong semantics, because an invariant assumed by
-// CompilerInvocation was violated: it expects that at most one of {gdwarfN,
-// line-tables-only} appear. If you assume that, then you can safely use
-// Args.hasArg to test whether a boolean flag is present without caring
-// where it appeared. And for this test, it appeared to the left of -gdwarf
-// which made it "win". This test could not detect that bug.
+// If We specify both /Z7 and -gdwarf we should get dwarf, not codeview.
// RUN: %clang_cl /Z7 -gdwarf /c -### -- %s 2>&1 | FileCheck
-check-prefix=Z7_gdwarf %s
----------------
I think Meta folks depend on a mode that emits both codeview and DWARF.
