This patch series is a follow up for the previous patch series for vector load [1]. Some of associated test cases show the benefits of this kind of structuring. Like the one on vect load, this patch series makes costing not call function vect_model_store_cost any more but next to the transform.
Most of them are organized according to the memory access types of vector store, hope it can make the review and bisection easy. The changes just follow the handlings in the function vect_model_store_cost first, then refine a bit by referring to the transform code, I also checked them with some typical test cases to verify. The whole series can be bootstrapped and regtested incrementally on: - x86_64-redhat-linux - aarch64-linux-gnu - powerpc64-linux-gnu P7, P8 and P9 - powerpc64le-linux-gnu P8, P9 and P10 By considering the current vector test buckets are mainly tested without cost model, I also verified the whole patch series was neutral for SPEC2017 int/fp on Power9 at O2, O3 and Ofast separately.
