           descr   Gcc has a bug in tree optimization. For adddf3,
                   -INF + -INF returns 0 without -fno-tree-vrp.
                   Debugging with -fdump-tree-all shows that
                   softfloat.c.021t.cleanup_cfg is ok but softfloat.c.023t.ssa
                   is broken.
