	gcc/
	* config/mips/mips.opt (mhard-float, msoft-float):  Make these
	control TARGET_HARD_FLOAT_ABI and TARGET_SOFT_FLOAT_ABI, rather
	than TARGET_HARD_FLOAT and TARGET_SOFT_FLOAT.  
	* config/mips/mips.h (mips16_hard_float): Delete.
	(TARGET_HARD_FLOAT_ABI, TARGET_SOFT_FLOAT_ABI):  Delete these
	definitions, and replace with....
	(TARGET_HARD_FLOAT, TARGET_SOFT_FLOAT): Define.
	* config/mips/mips.c (mips16_hard_float): Delete.  Replace
	all references with (TARGET_MIPS16 && TARGET_HARD_FLOAT_ABI).
	(MIPS_MARCH_CONTROLS_SOFT_FLOAT): Update comments.
	(override_options):  Replace MASK_SOFT_FLOAT references with
	MASK_SOFT_FLOAT_ABI.  Delete twiddling with MASK_SOFT_FLOAT
	and mips16_hard_float when TARGET_MIPS16.
