quad-float128.h (IBM128_TYPE): Explicitly use __ibm128, instead of trying to use long double.
2018-01-08 Michael Meissner <meissner@linux.vnet.ibm.com> * config/rs6000/quad-float128.h (IBM128_TYPE): Explicitly use __ibm128, instead of trying to use long double. (CVT_FLOAT128_TO_IBM128): Use TFtype instead of __float128 to accomidate -mabi=ieeelongdouble multilibs. (CVT_IBM128_TO_FLOAT128): Likewise. * config/rs6000/ibm-ldouble.c (IBM128_TYPE): New macro to define the appropriate IBM extended double type. (__gcc_qadd): Change all occurances of long double to IBM128_TYPE. (__gcc_qsub): Likewise. (__gcc_qmul): Likewise. (__gcc_qdiv): Likewise. (pack_ldouble): Likewise. (__gcc_qneg): Likewise.

(__gcc_qunord): Likewise. * config/rs6000/_mulkc3.c (toplevel): Include soft-fp.h and quad-float128.h for the definitions. (COPYSIGN): Use the f128 version instead of the q version. (INFINITY): Likewise. (__mulkc3): Use TFmode/TCmode for float128 scalar/complex types. * config/rs6000/_divkc3.c (toplevel): Include soft-fp.h and quad-float128.h for the definitions. (COPYSIGN): Use the f128 version instead of the q version. (INFINITY): Likewise. (FABS): Likewise.
