            Bug ID: 25545
           Summary: Bad diagnostic with -Wpacked
           Product: clang
           Version: 3.7
          Hardware: PC
                OS: Linux
            Status: NEW

struct a {
    struct b {
        short x;
        int y;
    } __attribute__((packed)) data;
};

/*
clang -Wpacked -o warnings.o -c warnings.c
warnings.c:3:13: warning: packed attribute is unnecessary for 'x' [-Wpacked]
        short x;
              ^
1 warning generated.
*/

clang --version:
Ubuntu clang version 3.7.0-svn251177-1~exp1 (branches/release_37) (based on
LLVM 3.7.0)
Target: x86_64-pc-linux-gnu
Thread model: posix

This does not reproduce for me if I do not use a nested struct.
