[kvm-unit-tests PATCH] Make the powerpc tests compilable with GCC 8

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

 



The new GCC 8.1 is optimizing the code with vector instructions.
However, we have not turned on the vector extension in our kvm-unit-test
code, so the tests crash when they hit such an instruction. Compile
the unit tests without vector extensions to avoid this problem.
