    • PR preprocessor/53469 - argument tokens of _Pragma miss virtual location · f3d25c65 
      Consider this short test snippet:

-------------------------8-------------------
    #define STRINGIFY(x) #x
    #define TEST(x) \
      _Pragma(STRINGIFY(GCC diagnostic ignored "-Wunused-local-typedefs")) \
      typedef int myint;

    void bar ()
    {
      TEST(myint)
    }
-------------------------8-------------------

The _Pragma is effectively ignored, and compiling with
-Wunused-local-typedefs warns on the local typedef, even though the
pragma should have prevented the warning to be emitted.

This is because when the preprocessor sees the _Pragma operator and
then goes to handle the first token ('GCC' here) that makes up its
operands, it retains the spelling location of that token, not its
virtual location.

Later when diagnostic_report_diagnostic is called to emit the warning
(or ignore it because of the pragma), it compares the location of the
first operand of the pragma with the location of the unused location,
(by calling linemap_location_before_p) and that comparison fails
because in this case, both locations should be virtual.

This patch fixes the issue by teaching the pragma handling to use
virtual locations.

Bootstrapped and tested on x86_64-unknown-linux-gnu against trunk.
