[PATCH] D145220: [X86][InstCombine] Simplify some `pternlog` intrinsics

[Phoebe Wang via Phabricator via llvm-commits]

pengfei added inline comments.


================
Comment at: llvm/lib/Target/X86/X86InstCombineIntrinsic.cpp:591-594
+  // Currently we only handle cases that convert directly to another instruction
+  // or cases where all the ops are constant.  This is because we don't properly
+  // handle creating ternary ops in the backend, so splitting them here may
+  // cause regressions. As the backend improves, uncomment more cases.
----------------
Maybe better to do it in FE and remove all these intrinsics finally?
