	PR libgcc/83112
	* config/rs6000/float128-ifunc.c (__addkf3_resolve): Use the
	correct type for all ifunc resolvers to silence -Wattribute-alias
	warnings.  Eliminate the forward declaration of the resolver
	functions which is no longer needed.

	PR libgcc/83103
	* config/rs6000/quad-float128.h (TF): Don't define if long double
	is IEEE 128-bit floating point.
	(TCtype): Define as either TCmode or KCmode, depending on whether
	long double is IEEE 128-bit floating point.
	(__mulkc3_sw): Add declarations for software/hardware versions of
	complex multiply/divide.
	(__divkc3_sw): Likewise.
	(__mulkc3_hw): Likewise.
	(__divkc3_hw): Likewise.
	* config/rs6000/_mulkc3.c (_mulkc3): If we are building ifunc
	handlers to switch between using software emulation and hardware
	float128 instructions, build the complex multiply/divide functions
	for both software and hardware support.
	* config/rs6000/_divkc3.c (_divkc3): Likewise.
	* config/rs6000/float128-ifunc.c (__mulkc3_resolve): Likewise.

	* config/rs6000/t-float128 (clean-float128): Delete _mulkc3-hw.c
	and _divkc3-hw.c.
