+       * config/mips/mips-protos.h (mips_emit_binary): Declare.
+       * config/mips/mips.c (mips_emit_binary): Make global.
+       (mips_set_mips16_mode): Turn off -mfix-r4000 in MIPS16 mode.
+       (mips_conditional_register_usage): Don't treat LO and HI as
+       register operands in MIPS16 mode.
+       (mips_mulsidi3_gen_fn): Use {u,}mulsidi3_{32,64}bit_mips16
+       for MIPS16 code.
+       * config/mips/predicates.md (muldiv_target_operand): New predicate.
+       (move_operand): Allow hilo_operand.
+       * config/mips/mips.md (mul<mode>3): Explicitly specify LO as the
+       target of MIPS16 multiplies, then move it into the target register.
+       (mul<mode>3_internal, *macc2, *msac2): Use muldiv_target_operand.
+       (<u>mulsidi3_32bit_mips16): New expander.
+       (<u>mulsidi3_32bit): Use muldiv_target_operand.
+       (<u>mulsidi3_32bit_r4000): Disable for ISA_HAS_DSP.
+       (<u>mulsidi3_64bit): Require !TARGET_MIPS16.  Split into
+       <u>mulsidi3_64bit_split.
+       (<u>mulsidi3_64bit_mips16): New expander.
+       (<u>mulsidi3_64bit_split): Likewise, using expansions from
+       two previous define_splits.
+       (<u>mulsidi3_64bit_hilo, *muls<u>_di, <u>msubsidi4): Use
+       muldiv_target_operand.
+       (<su>mulsi3_highpart): Use <su>mulsi3_highpart_split for MIPS16 code.
+       (<su>mulsi3_highpart_internal): Require !TARGET_MIPS16.

+       Use <su>muldi3_highpart_split for MIPS16 code.
+       (<su>muldi3_highpart_internal): Renamed from <su>muldi3_highpart.
+       Require !TARGET_MIPS16.  Split into <su>muldi3_highpart_split.
+       (<su>muldi3_highpart_split): New expander.
+       (<u>mulditi3): Explicitly specify LO as the target of MIPS16
+       multiplies, then move it into the target register.

+       (divmod<mode>4, udivmod<mode>4): Turn into define_expands.
+       Use <u>divmod<mode>4_split for MIPS16 code, then explicitly
+       move LO into operand 0.
+       (divmod<mode>4_internal, udivmod<mode>4_internal): Renamed
+       from <u>divmod<mode>4.  Use muldiv_target_operand.
