1613 * - we use an approach similar to the x86 abi: reserve a register (r30) to hold
1615 * - The full-aot trampolines need access to the GOT of mscorlib, so we store
1616 * in in the 2. slot of every GOT, and require every method to place the GOT
1617 * address in r30, even when it doesn't access the GOT otherwise. This way,
1618 * the trampolines can compute the mscorlib GOT address by loading 4(r30).
1623 * PPC64 uses function descriptors which greatly complicate all code, since
1624 * these are used very inconsistently in the runtime. Some functions like
1625 * mono_compile_method () return ftn descriptors, while others like the
1626 * trampoline creation functions do not.
1627 * We assume that all GOT slots contain function descriptors, and create
1628 * descriptors in aot-runtime.c when needed.
1629 * The ppc64 abi uses r2 to hold the address of the TOC/GOT, which is loaded
1630 * from function descriptors, we could do the same, but it would require
1631 * rewriting all the ppc/aot code to handle function descriptors properly.
1632 * So instead, we use the same approach as on PPC32.
1633 * This is a horrible mess, but fixing it would probably lead to an even bigger

1884 * arch_emit_specific_trampoline_pages:

1887 * lookup both the generic trampoline code and the data argument.
1888 * This page can be remapped in process multiple times so we can get an
1889 * unlimited number of trampolines.
1890 * Specifically this implementation uses the following trick: two memory pages
1891 * are allocated, with the first containing the data and the second containing the trampolines.
1892 * To reduce trampoline size, each trampoline jumps at the start of the page where a common
1893 * implementation does all the lifting.
1894 * Note that the ARM single trampoline size is 8 bytes, exactly like the data that needs to be stored
1895 * on the arm 32 bit system.

7625 * These include the following:
7626 * - specific trampolines
7627 * - static rgctx invoke trampolines
7629 * These trampolines have the same code, they are parameterized by GOT
7631 * They are defined in this file, in the arch_... routines instead of
7632 * in tramp-<ARCH>.c, since it is easier to do it this way.
7636 * When running in aot-only mode, we can't create specific trampolines at
7637 * runtime, so we create a few, and save them in the AOT file.
7638 * Normal trampolines embed their argument as a literal inside the
7639 * trampoline code, we can't do that here, so instead we embed an offset
7640 * which needs to be added to the trampoline address to get the address of
7641 * the GOT slot which contains the argument value.
7642 * The generated trampolines jump to the generic trampolines using another
7643 * GOT slot, which will be setup by the AOT loader to point to the
7644 * generic trampoline code of the given type.
7648 * FIXME: Maybe we should use more specific trampolines (i.e. one class init for
