[LLVMdev] custom lowering with multiple results

[Edmund Grimley-Evans]

There have been some useful replies to my question. In particular, Eli Friedman explained that my change to LegalizeDAG.cpp was wrong and suggested that I use a MERGE_VALUES node in ARMISelLowering.cpp.

Unfortunately, that hasn't solved the problem I was having. I still get the same old assertion failure: "#operands for dag node doesn't match .td file!"

However, here's an updated version of the patch, for the record.
