[Kees Cook via Phabricator via cfe-commits]

kees added inline comments.


================
Comment at: clang/test/SemaCXX/array-bounds.cpp:240
 
-    ((char*)foo)[sizeof(foo)] = '\0';  // expected-warning {{array index 32768 is past the end of the array (which contains 32768 elements)}}
+    ((char*)foo)[sizeof(foo)] = '\0';  // expected-warning {{array index 32768 is past the end of the array (which contains 4096 elements)}}

Perhaps show both element count and byte offset?

`array index $count is $(bytes - end_of_array_in_bytes) past the end of the array (which contains $end_of_array_in_bytes bytes of $array_max_index elements)`
