[PATCH] D17918: [ELF] - Issue an error if trying to generate relocatable from objects having mixed splitstacks.

>It should still get the same type of handling as GNU-split-stack, though. I see no reason to handle one (even if "handle" is discarding if the output is not relocatable) but not the other.
Thats because -r does not need to handle it. We should handle the other one for completeness, but that is not relative to this patch, so should be done separatelly.

>But I think the latter messages have a better idea: Simply rejecting split-stack objects (unless you plan on adding the rest of the support, including changing function prologues) seems like the >most appropriate thing to do right now.
So if we are not going to support splitstacks, I would also vote for this. (I can just update this patch, will cut excessive logic and update the tests, probably will also add few testcases).

But if it is reasonable to have splitstacks, then I can implement this feature I think.

Rui, Rafael, what do you think about this ?

George.
