This is exactly which got me started into trying to understand what it
takes to analyse s390 on x86_64. . Hence I've referenced the function
which is supposed to verify that a particular combination of host and
target is supported. I'm now interested in understanding why s390 on
x86_64 is not supported.
Crossing arch always makes me nuts. I'd recommend to
view s390 vmcores
in a s390 machine. But if you just want to do some investigation on this
topic, I think s390 guys can give more details. I suppose they've tried it?
