1611 * - we use an approach similar to the x86 abi: reserve a register (r30) to hold
1613 * - The full-aot trampolines need access to the GOT of mscorlib, so we store
1614 * in in the 2. slot of every GOT, and require every method to place the GOT
1615 * address in r30, even when it doesn't access the GOT otherwise. This way,
1616 * the trampolines can compute the mscorlib GOT address by loading 4(r30).
1621 * PPC64 uses function descriptors which greatly complicate all code, since
1622 * these are used very inconsistently in the runtime. Some functions like
1623 * mono_compile_method () return ftn descriptors, while others like the
1624 * trampoline creation functions do not.
1625 * We assume that all GOT slots contain function descriptors, and create
1626 * descriptors in aot-runtime.c when needed.
1627 * The ppc64 abi uses r2 to hold the address of the TOC/GOT, which is loaded
1628 * from function descriptors, we could do the same, but it would require
1629 * rewriting all the ppc/aot code to handle function descriptors properly.
1630 * So instead, we use the same approach as on PPC32.
1631 * This is a horrible mess, but fixing it would probably lead to an even bigger

1882 * arch_emit_specific_trampoline_pages:

1885 * lookup both the generic trampoline code and the data argument.
1886 * This page can be remapped in process multiple times so we can get an
1887 * unlimited number of trampolines.
1888 * Specifically this implementation uses the following trick: two memory pages
1889 * are allocated, with the first containing the data and the second containing the trampolines.
1890 * To reduce trampoline size, each trampoline jumps at the start of the page where a common
1891 * implementation does all the lifting.
1892 * Note that the ARM single trampoline size is 8 bytes, exactly like the data that needs to be stored
1893 * on the arm 32 bit system.
