+
+	* config/mips/crti.asm: Add changes for mips16. mips16 uses
+	register 7 as RA instead of $31.
+	* config/mips/crtn.asm: Ditto.
+	* config/mips/mips.c (mips_move_2words): Add case for
+	TARGET_MIPS16 when HOST_BITS_PER_WIDE_INT >= 64.
+	(compute_frame_size): Fix typo.
+	(save_restore_insns): Ditto.  Make documentation about using
+	register $7 as return register more precise.
+	(mips_expand_epilogue): Fix comment. Add code to work around not
+	being able to add to the stack pointer directly.
+	* config/mips/mips.h (EH_RETURN_DATA_REGNO): Change register number
+	to 2 for TARGET_MIPS16 as we need 6 and 7 as clobbers in the
+	epilogue.
