[Qemu-devel] [PATCH 3/7] target/xtensa: don't continue translation after exception

[Max Filippov <jcmvbkbc@gmail.com>]

There's no point in continuing translating guest instructions once an
unconditional exception is thrown.
There's also no point in updating pc before any instruction is
translated, don't do it.
