Do you think it's better to change it with another patch since I think it's not a SVE special case (NEON and X86 have the same issue)? Changing the default loop count for all tests needs more time to run the tests and make the tests easier to time out. And I've no idea about how to set the suitable value to balance the time and effectiveness. I think some cases can actually trigger the C2 compilation if using default iterations=100. However, it cannot for simple cases like min/max.

Sure, I will do it later then. Thanks a lot!
