commit r14-3588-g9afdebbd5f581bdfb1f94dd944636c09ca553c5c
Author: Richard Biener <rguenther@suse.de>

    Adjust gcc.target/i386/pr52252-{atom,core}.c
    
    The following adjusts the testcases to force 128bit vectorization
    to make them more robust when for example adding -march=cascadelake
    
            * gcc.target/i386/pr52252-atom.c: Add -mprefer-vector-width=128.
            * gcc.target/i386/pr52252-core.c: Likewise.
