--- Comment #4 from Sebastian Huber <address@hidden> ---
The C code test case works at least on arm, bfin, epiphany, lm32, m32c, m68k,
mips, moxie, nios2, or1k, powerpc, sh, sparc64, sparc, v850, and x86_64.

The use case for this is that high level configuration code can pass some
information to low level initialization code. During the execution of the low
level initialization code the read-only or read-write global data may be not
available, e.g. due to some magic address mapping mode of a processor.
Addresses may be used as configuration constants in this scenario, e.g. to get
the location and size of the initialization stack.
