Replace UNSPEC_COPYSIGN with copysign
2023-07-25 Michael Meissner <meissner@linux.ibm.com>
gcc/
* config/rs6000/rs6000.md (UNSPEC_COPYSIGN): Delete.
(copysign<mode>3_fcpsg): Use copysign RTL instead of UNSPEC.
(copysign<mode>3_hard): Likewise.
(copysign<mode>3_soft): Likewise.
* config/rs6000/vector.md (vector_copysign<mode>3): Use copysign RTL
instead of UNSPEC.
* config/rs6000/vsx.md (vsx_copysign<mode>3): Use copysign RTL instead
of UNSPEC.
