Hi Wolfgang,

You are right, especially as the resulting start address of the global data is usually also used as the top of the internal stack. Guess we should align it on 16 bytes, to be sure.
Yes, we already had this 8-byte stack align problem on ARM, IIRC.
BTW - this uncovers a number of other problems.
commit 800eb096 "POST cleanup." inserts a single data word between global data and initial stack, thus also breaking stack alignment.
I think this approach is wrong, the POST word should be made part of the global_data instead.
Good idea.
Cheers, Stefan
