That would remove this code

Hi, I have two questions about the above method of the SelectionDAGISel class. 1. The overrides in PPCDAGToDAGISel and in I64DAGToDAGISel are identical (except for PPCISD::FIRST_NUMBER vs. IA64ISD::FIRST_NUMBER). Maybe, this means that it would be better if SelectionDAGISel had default implementation? That would remove this code duplication. If desired, SelectionDAGISel can have both

In the 2.3 release, we included a list of the major LLVM API changes. If you are working on upgrading your code from 2.3 to 2.4, I'd appreciate it if you could compile a list of the major stumbling blocks you have, so that others can benefit from your experience. Please send any info to the list, thanks! -Chris
