[kvm-unit-tests PATCH v2 01/13] riscv: Call abort instead of assert on unhandled exceptions

[Andrew Jones]

We should call abort() instead of assert() on an unhandled
exception since assert() calls abort() anyway after a useless
"assert failed: 0" message. We can also skip dumping the
exception stack and just unwind from the stack frame where
the exception occurred.
