+Subject: [PATCH] xtensa: fix libgcc build with --text-section-literals
+
+Functions __muldf3_aux, __divdf3_aux, __mulsf3_aux and __divsf3_aux
+don't start with leaf_entry, so they need explicit .literal_position,
+otherwise libgcc build fails in the presence of --text-section-literals.
+
+2016-02-17  Max Filippov  <jcmvbkbc@gmail.com>
+libgcc/
+	* config/xtensa/ieee754-df.S (__muldf3_aux, __divdf3_aux): Add
+	.literal_position before the function.
+	* config/xtensa/ieee754-sf.S (__mulsf3_aux, __divsf3_aux):
+	Likewise.
