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. Signed-off-by: Thomas Huth <thuth@redhat.com> --- powerpc/Makefile.common | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
