+       * elf/tls-macros.h (__TLS_CALL_CLOBBERS <__powerpc__>): Remove r3.
+       Define and use for __powerpc64__ too.
+       (TLS_LD <__powerpc__>): Add r3 to clobbers.
+       (TLS_GD <__powerpc__>): Set asm output.  Make __result r3 reg.
+       (TLS_GD <__powerpc64__>): Make __result r3 reg.
+       (TLS_IE <__powerpc64__>): Relax output constraint.
