Portable dumper ideas

I had trouble understanding the alignment code, especially align_table. Ideas: Use ALIGNOF maybe? The maximum alignment required should be perhaps (from opaque.h) typedef union { struct { Lisp_Object obj; } obj; struct { void *p; } p; struct { double d; } d; } max_align_t; We could move max_align_t to lisp.h, and have size_t max_alignment = ALIGNOF (max_align_t); Wouldn't we get a tremendous performance boost by having the lrecord_implementations_table indices be constant? We would lose a level of indirection on every FOOP, because it would not have to examine lrecord_implementations_table itself.
