You're still missing the point that the simtest-howto.html stuff
is generally not for port maintainers but for *other* GCC

Correct.  Of course, you need for newlib to generate and for the
simulator to have special calls for e.g. file operations and
memory allocation.

If there's already an AVR simulator, you shouldn't start from
scratch; just connect it to the sim framework.  See ppc, arm or
sh simulators for instance.  No documentation, but plenty of
source code.  When starting from scratch and for gcc testing,
CGEN or igen would be better than SID, because SID needs more
than is covered by the simtest-howto.html instructions.
