[PATCH] D129642: [Sema] Tweak diagnostic logic so suppress-in-hedaer logic works in tools too.

[Kadir Cetinkaya via Phabricator via cfe-commits]

kadircet added inline comments.


================
Comment at: clang/lib/Sema/SemaDecl.cpp:1784
 
   if (D->isInvalidDecl() || D->isUsed() || D->hasAttr<UnusedAttr>())
     return false;
----------------
i think we can just bail out early here when the main file is a header file 
(i.e. lang opts have `IsHeaderFile` set).
