================
Comment at: clang/test/CodeGenCXX/matrix-type-operators.cpp:374
+  // CHECK-NEXT:    %1 = bitcast [90 x double]* %value to <90 x double>*
+  // CHECK-NEXT:    %2 = load <90 x double>, <90 x double>* %1, align 8
+  // CHECK-NEXT:    %call = call double @_ZN14DoubleWrapper1cvdEv(%struct.DoubleWrapper1* %w1)

Yes, this looks great, thanks!
