[LLVMdev] Custom Opcodes versus built-in opcodes
...method
to use in a Custom Lowering function? Even the other backends use
getNode in their lowering functions with custom opcodes.
This is from SparcISelLowering.cpp
CompareFlag = DAG.getNode(SPISD::CMPFCC, MVT::Flag, LHS, RHS);
if (SPCC == ~0U) SPCC = FPCondCCodeToFCC(CC);
Opc = SPISD::BRFCC;
}
return DAG.getNode(Opc, MVT::Other, Chain, Dest,
DAG.getConstant(SPCC, MVT::i32), CompareFlag);

Actually, I'm wrong, sorry about that. It looks like the encoding is
in the definition of the enum:

[LLVMdev] Custom Opcodes versus built-in opcodes
I am using lowering instructions and using custom opcodes that I can
more easily directly map to my backend. These opcodes are then used to
emit a custom set of instructions into the MachineBasicBlock. I've been
able to get one to work correctly, however, I've ran into an issue where
my second one is being confused as a FRAMEADDR opcode instead of my
opcode.
