re PR bootstrap/77993 (bootstrap failure on PowerPC/Linux)
2016-11-03 Michael Meissner <meissner@linux.vnet.ibm.com>
PR target/77993
* config/rs6000/rs6000.h (FLOAT128_IBM_P): Do not allow IFmode or
ICmode unless we have standard PowerPC floating point.
* config/rs6000/rs6000.md (FP iterator): Likewise.
(FMOVE128 iterator): Likewise.
