[PATCH] D105909: [clang][CallGraphSection] Add type id metadata to indirect call and targets

[Matt Morehouse via Phabricator via cfe-commits]

morehouse added inline comments.


================
Comment at: clang/lib/CodeGen/CodeGenModule.cpp:2068
+    EmittedMDIdGeneralized = true;
+  }
+
----------------
This code also seems unnecessary as it puts metadata on function definitions.


================
Comment at: clang/lib/CodeGen/CodeGenModule.cpp:2177
+      !CodeGenOpts.SanitizeCfiCanonicalJumpTables ||
+      CodeGenOpts.CallGraphSection)
     CreateFunctionTypeMetadataForIcall(FD, F);
----------------
Also seems unnecessary.


================
Comment at: clang/test/CodeGen/call-graph-section.c:20
+
+// CHECK-DAG: define {{(dso_local)?}} i32 @baz({{.*}} !type [[F_TPRIMITIVE:![0-9]+]]
+int baz(char a, float b, double c) {
----------------
Do we still expect type metadata on function definitions on the latest diff?


================
Comment at: clang/test/CodeGen/call-graph-section.c:39
+  fp_qux(0, 0, 0);
+}

I mean an indirect call with a type like this:

```
void foo(struct MyStruct s)
```

Currently all the tests use primitive types.
