matching. This design just fundamentally didn't work because ADDSUB is available prior to any legal lowerings of BLENDI nodes. Instead, we have a dedicated ADDSUB synthetic ISD node which is pattern matched trivially into the instructions. These nodes are then recognized by both the existing and a trivial new lowering combine in the backend. Removing these patterns required adding 2 missing shuffle masks to the DAG combine, without which tests would have failed. Added the masks and a helpful assert as well to catch if anything ever goes wrong here. llvm-svn: 217851 |
