Anton Bikineev	cc7e74753a	[CodeGenCXX] Treat 'this' as noalias in constructors ... This is currently a clang extension and a resolution of the defect report in the C++ Standard. Differential Revision: https://reviews.llvm.org/D46441 llvm-svn: 344150	2018-10-10 16:14:51 +00:00
Reid Kleckner	563f0e852c	Use comdats to avoid double initialization of weak data ... Initializers of global data that can appear multiple TUs (static data members of class templates or __declspec(selectany) data) are now in a comdat group keyed on the global variable being initialized. On non-Windows platforms, this is a code size and startup time optimization. On Windows, this is necessary for ABI compatibility with MSVC. Fixes PR16959.
