[PATCH] D103138: [AMDGPU] [IndirectCalls] Don't propagate attributes to address taken functions and their callees

[Jay Foad via Phabricator via llvm-commits]

foad added inline comments.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUPropagateAttributes.cpp:118
 
+  CallGraph *ModuleCG;
+
----------------
Add the nullptr initializion here instead of in the constructor?


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUPropagateAttributes.cpp:248
+
+    std::queue<CallGraphNode *> SubGraph;
+    SubGraph.push(CGN);
----------------
It's more common to use a SmallVector for this, with push_back and pop_back_val.


================
Comment at: llvm/lib/Target/AMDGPU/AMDGPUPropagateAttributes.cpp:234-237
+  if (!ModuleCG) {
+    llvm_unreachable("Call graph not valid");
+    return Changed;
+  }
----------------

Then it's a bad choice :) I agree with Matt. `assert(CG)` or `assert(CG && "message")` are shorter and simpler and more familiar because they're already ubiquitous throughout llvm.
