Is that correct?

Is this correct ?

Hi, this is the most important patch for RVV auto-vectorization support.
It supports WHILE_LEN pattern to not only decrement Loop control IV counter,
but also adjust data reference address pointer by WHILE_LEN.
1. Single control loop (vec_num == 1 && ncopies == 1):
int
12 matches
