David has fixed this recently, but just for AIX. Generally, -Wno-psabi
is beneficial for all targets if it is needed on just one, I've committed
following:
2016-12-15 Jakub Jelinek <ja...@redhat.com>
* gcc.dg/tree-ssa/forwprop-35.c: Use -Wno-psabi everywhere.
* gcc.dg/torture/pr78515.c: Likewise.
* gcc.dg/pr69634.c: Likewise.
