	gcc/
	Fix up MIPS16 hard float and add support for complex.

	* config/mips/mips.h (TARGET_HARD_FLOAT_ABI): New.
	(TARGET_SOFT_FLOAT_ABI): New.
	(TARGET_CPU_CPP_BUILTINS): Define __mips_hard_float and
	__mips_soft_float to reflect the ABI in use, not whether the
	FPU is directly accessible (e.g., in MIPS16 mode).
	(UNITS_PER_HWFPVALUE): Use TARGET_SOFT_FLOAT_ABI.
	(UNITS_PER_FPVALUE): Likewise.

	* config/mips/mips.c (mips_expand_call): Remove redundant
	TARGET_MIPS16 check.
	(mips_arg_regno): New.
	(function_arg_advance): When setting bits in cum->fp_code for
	MIPS16, don't subtract 1 from cum->arg_number, since it is now
	zero-based.
	(function_arg): Use mips_arg_regno.
	(mips_return_mode_in_fpr_p): New.
	(mips16_call_stub_mode_suffix): New.

	(mips_output_function_prologue): Test mips16_hard_float, not
	!TARGET_SOFT_FLOAT, to decide when a function stub is required.
	(mips_expand_epilogue): Call MIPS16 helper routines to copy
	return value into a floating-point register.
	(mips_can_use_return_insn): Use mips16_cfun_returns_in_fpr_p.
	(mips_function_value): Rewrite to use mips_return_mode_in_fpr_p.
	(mips16_fp_args): Handle MIPS32r2 ISA which supports
	TARGET_FLOAT64, and use mfhc1/mthc1 to copy the most significant
	word of double arguments from or to the high bits of 64-bit
	floating point registers.
	(build_mips16_function_stub): Fill in DECL_RESULT for stubdecl.
	(mips16_fpret_double): New helper function.
	(build_mips16_call_stub): Use mips16_return_mode_in_fpr_p.  Add
	support for complex modes.  Fill in DECL_RESULT for stubdecl.
