Currently, for MS, the linkage for the inheriting constructors is set to internal. However, the comdat attribute is also set like: define internal noundef ptr @"??0?$B@_N@@qeaa@AEBVF@@aebua@@@z"(ptr noundef nonnull returned align 1 dereferenceable(1) %this, ptr noundef nonnull align 1 dereferenceable(1) %0, ptr noundef nonnull align 1 dereferenceable(1) %1) unnamed_addr comdat This could cause linker to fail. The change is to remove comdat attribute for the inheriting constructor to make linker happy. Differential Revision: https://reviews.llvm.org/D158538
