[LLVMdev] Help on DAG pattern matching string
Hello, Everyone
> TargetSelectoinDAG.td and then why the two versions are "identical" in
> TableGen's mind.
That's correct. The patterns are identical since the types of operands
involved are the same. DAG pattern matching is done before regalloc,
there are not regclasses actually at that point, thus both patterns
tries to select the same thing...
