+       * config/mips/mips.h (CONSTANT_POOL_COST): Move to...
+       * config/mips/mips.c: ...here and set to 4 for TARGET_MIPS16.
+       (mips16_constant_cost, mips_immediate_operand_p, mips_binary_cost)
+       (mips_fp_mult_cost, mips_fp_div_cost, mips_sign_extend_cost)
+       (mips_zero_extend_cost): New functions.
+       (mips_rtx_costs): Treat COMPARE constants as having zero cost.
+       Use the new functions.  Tweak many cost estimates, both here
+       and in the new subroutines.  Return false when the cost of the
+       operands has not been calculated.  Check for *clear_upper32.
+       Check for floating-point multiply-add, reciprocal and rsqrt
+       patterns.  Handle comparison and rotation codes.
