common-trampoline: Ensure omission of frame-pointer
...
ci/woodpecker/push/woodpecker Pipeline was successful
Details
Some architecture-specific implementations of the FETCH_LINKPTR
(e.g. the one for x86) attempt to find the linkptr relative to the
stack pointer. Therefore, they make assumption about the value of
the SP at the point where the FETCH_LINKPTR code is executed. This
means that we don't want the C compiler to mess with our SP.
For this purpose, local variables in this function are currently
declared using the register storage specifier. Additionally, we
need to make sure that a frame pointer is /always/ omitted for
this function. On x86 Alpine, the frame pointer is presently not
omitted with GCC 13 when using -Os, therefore the tests segfault
with -Os on Alpine presently.

x0 hast to be 0 in case setcontext is called with a context acquired by getcontext.

libucontext: Add patch fixing return values of get/set/swapcontext
...
The arm ABI defines that the value in register r0 is used as the return
value of a function. To indicate success for get/set/swapcontext (return
value of 0) the register r0 must contain zero at the end of the function
call. Thus set r0 to zero and store it in the context. This context
is restored later and indicate successful execution, because r0 is 0.
The order registers are stored has changed so that only one additional
instruction (mov r0, #0 ) needs to be added to fix the return value
bug for get/set/swapcontext.
