Zvi Rackover d91a5044bd LoopVectorize: MaxVF should not be larger than the loop trip count ... Summary: Improve how MaxVF is computed while taking into account that MaxVF should not be larger than the loop's trip count. Other than saving on compile-time by pruning the possible MaxVF candidates, this patch fixes pr34438 which exposed the following flow: 1. Short trip count identified -> Don't bail out, set OptForSize:=True to avoid tail-loop and runtime checks. 2. Compute MaxVF returned 16 on a target supporting AVX512. 3. OptForSize -> choose VF:=MaxVF. 4. Bail out because TripCount = 8, VF = 16, TripCount % VF !=0 means we need a tail loop. With this patch step 2. will choose MaxVF=8 based on TripCount.
