s390.c (s390_select_ccmode): Do not attempt to use CCL, CCL1, or CCL2 modes with floating point operations. 

2003-08-01  Andreas Krebbel <krebbel1@de.ibm.com>

	* config/s390/s390.c (s390_select_ccmode): Do not attempt to use CCL,
	CCL1, or CCL2 modes with floating point operations.

	* config/s390/s390.md ("*addsf3_cc", "*addsf3_cconly", "*adddf3_cc",
	"*adddf3_cconly", "*subsf3_cc", "*subsf3_cconly", "*subdf3_cc",
	"*subdf3_cconly"): New insns.
	("*negabssi2", "*negabsdi2", "*negabsdf2", "*negabssf2"): Likewise.
