Er, I tested this with r247821 and it doesn't work for me.

$ cat as.c
char *allocate(int) __attribute__((__malloc__, __alloc_size__(1)));

$ clang as.c -fsyntax-only
as.c:1:48: warning: unknown attribute '__alloc_size__' ignored
      [-Wunknown-attributes]
char *allocate(int) __attribute__((__malloc__, __alloc_size__(1)));
                                               ^
1 warning generated.

I don't see the string "alloc_size" anywhere inside clang's codebase?
