================
Comment at: llvm/lib/Target/X86/X86InstCombineIntrinsic.cpp:588
+  bool BCIsConst = isa<Constant>(B) && isa<Constant>(C);
+  bool ABCIsConst = isa<Constant>(A) && isa<Constant>(B) && isa<Constant>(C);

----------------
If everything is const can we someone use the immediate as a lookup table instead of manually describing every case?
