[PATCH] IBM Z: Emit vector alignment hints for strlen

2020-10-18 Thread Stefan Schulze Frielinghaus via Gcc-patches
In case the vectorized version of strlen is used, then each memory access inside the loop is 16-byte aligned. Thus add this kind of information so that vector alignment hints can later on be emitted. Bootstrapped and regtested on IBM Z. Ok for master? gcc/ChangeLog: * config/s390/s390.
