We have observed that noreg was being generated due to a bug in FastIsel and was not being detected during emission. It happens that in the Asm emission there is an assertion that detects this in getRegisterName() from the tbl-generated file PPCGenAsmWriter.inc. However, when emitting an Obj file, invalid registers can be emitted given that no check are made in getBinaryCodeFromInstr() from PPCGenMCCodeEmitter.inc. In order to cover all cases this adds an assertion for reg operands in LowerPPCMachineInstrToMCInst. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@232525 91177308-0d34-0410-b5e6-96231b3b80d8
