s390.md (UNSPEC_COPYSIGN): New constant.
2007-03-19 Andreas Krebbel <krebbel1@de.ibm.com>
* config/s390/s390.md (UNSPEC_COPYSIGN): New constant.
(op_type attribute): RRF instruction type added.
(fT0): New mode attribute.
("*movdi_64dfp", "*movdf_64dfp", "*neg<mode>2_nocc", "*abs<mode>2_nocc",
"*negabs<mode>2_nocc", "copysign<mode>3"): Insn definitions added.
* config/s390/s390.h (SECONDARY_MEMORY_NEEDED): Due to a new instruction
no secondary memory is needed when moving DFmode values between GPRs
and FPRs.
