[kvm-unit-tests v2 PATCH 2/2] x86: don't compare two global objects' addrs for inequality

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Two global objects can't have the same address in C. Clang uses this
fact to omit the check on the first iteration of the loop in
check_exception_table. Avoid compariting inequality by using less-than.
