Really digging in the archives this time :)
ia64-specific:
http://lists.xen.org/archives/html/xen-ia64-devel/2008-03/msg00126.html
http://lists.xen.org/archives/html/xen-ia64-devel/2008-12/msg00070.html
x86_64-specific (missing red zone support)
http://lists.xen.org/archives/html/xen-ia64-devel/2008-02/msg00251.html
So I guess it could be OK on arm, but you have to make sure that Mini-OS
implements the whole ABI that gcc will use. Testing is not enough, I got
hit by the red zone for instance.
