commit 7c75a2a3bfdcc2fc792d730562c677d513347d1c
Author: Sandra Loosemore <sandra@codesourcery.com>
Date:   Fri Jan 24 11:41:31 2020 -0800

    Add -fdelete-null-pointer-checks to some C++ testcases.
    
    These testcases were failing on nios2-elf, which defaults to
    -fno-delete-null-pointer-checks.
