[X86] Adding a new instruction JUMPB
...the SelectionDAG node addition ( http://llvm.org/docs/ExtendingLLVM.html#adding-a-new-selectiondag-node) the right guide to follow? - Is there an example of how to enforce some assertions when assembling on say the computed operands for a given instruction? For example, if the MachineInstr for the JUMPB instruction was computed as an offset between the current instruction and a label, and the distance was out-of-bounds indicating a bad MachineInstr was used, is there a way to error out? Is this purely implemented in the legalisation of the instruction? - I've recently heard about and listened...
