11 /* Remaining AOT-only work:
12 * - optimize the trampolines, generate more code in the arch files.
13 * - make things more consistent with how elf works, for example, use ELF
15 * Remaining generics sharing work:
16 * - optimize the size of the data which is encoded.
17 * - optimize the runtime loading of data:
18 * - the trampoline code calls mono_jit_info_table_find () to find the rgctx,
19 * which loads the debugging+exception handling info for the method. This is a
20 * huge waste of time and code, since the rgctx structure is currently empty.
21 * - every shared method has a MonoGenericJitInfo structure which is only really
22 * used for handling catch clauses with open types, not a very common use case.

589 * these are used very inconsistently in the runtime. Some functions like
590 * mono_compile_method () return ftn descriptors, while others like the

592 * We assume that all GOT slots contain function descriptors, and create
593 * descriptors in aot-runtime.c when needed.
594 * The ppc64 abi uses r2 to hold the address of the TOC/GOT, which is loaded
595 * from function descriptors, we could do the same, but it would require
596 * rewriting all the ppc/aot code to handle function descriptors properly.
597 * So instead, we use the same approach as on PPC32.
