Hello, are there any updates on this? I also think not generating any vector
instruction for interrupt routine will be good, since interrupt handler needs
to be fast, but if v is enabled in march, it will generate extra unnecessary
vector save and restore in interrupt routine code, which adds extra cost for an
interrupt handler.
