Hi, The comment at the top of mfbt/DebugOnly.h includes this text:
* Note that DebugOnly instances still take up one byte of space, plus padding, * when used as members of structs. I'm in the process of making js::HashTable (a very common class) smaller by converting some DebugOnly fields to instead be guarded by |#ifdef DEBUG| (bug 1038601). Below is a list of remaining DebugOnly members that I found using grep. People who are familiar with them should inspect them to see if they belong to classes that are commonly instantiated, and thus if some space savings could be made. Thanks.
