+        LP: #693425
+        Backport from mainline:
+
+        gcc/
+        * config/spu/spu.md ("mov<mode>"): Use nonimmediate_operand
+        predicate for destination operand.
+        * config/spu/spu.c (spu_expand_mov): If move destination is an
+        invalid subreg, perform move in the subreg's inner mode instead.
