[Mono-devel-list] Question Jit Trampolines

[Zoltan Varga]

                              Hi,

  Contrary to the comments in tramp-x86.c, x86_magic_trampoline is used for
all methods, not just virtual methods. If the call is not virtual, the
call site itself
is rewritten so it calls the real method next time, not the trampoline.
This is done by this line:
					InterlockedExchange ((gint32*)(code + 2), (guint)addr -
((guint)code + 1) - 5);

              Zoltan
