[PATCH] D125114: [SimplifyLibCalls] handle subobjects of constant aggregates

[Nikita Popov via Phabricator via llvm-commits]

nikic added inline comments.


================
Comment at: llvm/lib/Analysis/ConstantFolding.cpp:660
+
+  SmallVector<Constant*, 256> Ar;
+  Type *Int8Ty = Type::getInt8Ty(GV->getContext());
----------------
There is no need to convert the values to ConstantInt, you should be able to use the `ConstantDataArray::get()` constructor with the SmallVector directly.


================
Comment at: llvm/lib/Analysis/ValueTracking.cpp:4109
   // Look through bitcast instructions and geps.
   V = V->stripPointerCasts();
 
----------------
You can replace this with stripAndAccumulateOffsets(), in which case you don't need explicit handling for GEPs.
