[cfe-dev] Status of "-parse-print-callbacks"

[Jon Simons]

I am wondering, what is the status of using the "-parse-print-callbacks"
flag for clang-cc?

Should it succeed and fail when normal parsing would succeed and fail?

I ask because I see discrepancies:

   # cat test.c
   typedef struct foo { int x; } foo;
   void test() {
     foo *foo;
     foo->x = 0;
   }
   # clang-cc test.c
   # clang-cc -parse-print-callbacks test.c 1>/dev/null
   test.c:4:6: error: expected identifier or '('
     foo->x = 0;
        ^
   test.c:4:6: error: parse error
   2 diagnostics generated.

Is this something that warrants a PR and/or following up on?  Or is
"-parse-print-callbacks" something that might not be worth updating
because C++ parsing is still in development?
