thank you very much! That is interessting so I have
additional questions. The switch-case block in
"mono_get_trampoline_func()" in mini-trampolines.c
tells me which trampoline type calls which C-function.

Q1: Besides the monitor enter/exit trampolines, there
are other trampoline types which might not end up
in a C-function (and use, for example, optimized code

Q2: Do unbox trampolines do any kind of patching, i.e.,
modifying native code? As I understood, unbox trampolines
are only needed when a method of a value type is going to
be called but the instance of the value is boxed (e.g., casted
to object in C#). And unbox trampolines are only handled/
inserted by the magic trampoline. Do I understand it correct?

With kind regards,
Martin Däumler
