-/* Remaining AOT-only work:
- * - optimize the trampolines, generate more code in the arch files.
- * - make things more consistent with how elf works, for example, use ELF
- * relocations.
- * Remaining generics sharing work:
- * - optimize the size of the data which is encoded.
- * - optimize the runtime loading of data:
- * - the trampoline code calls mono_jit_info_table_find () to find the rgctx,
- * which loads the debugging+exception handling info for the method. This is a
- * huge waste of time and code, since the rgctx structure is currently empty.
