[PATCH] D126455: [FuncSpec] Make the Function Specializer part of the IPSCCP pass.

[Momchil Velikov via Phabricator via llvm-commits]

chill added inline comments.


================
Comment at: llvm/lib/Transforms/IPO/FunctionSpecialization.cpp:695
 
-  LLVM_DEBUG(dbgs() << "FnSpecialization: Number of specializations = "
-                    << NumFuncSpecialized << "\n");
-
-  // Remove any ssa_copy intrinsics that may have been introduced.
-  removeSSACopy(M);
-  return Changed;
+  // If the function has been completely specialized, the original function
+  // is no longer needed. Mark it unreachable.
----------------
This is better placed outside of `rewriteCallSites`, perhaps just after the call to `rewriteCallSites`.
