Fangrui Song	789a46f2d7	[CodeGenModule] Assume dso_local for -fpic -fno-semantic-interposition ... Summary: Clang -fpic defaults to -fno-semantic-interposition (GCC -fpic defaults to -fsemantic-interposition). Users need to specify -fsemantic-interposition to get semantic interposition behavior. Semantic interposition is currently a best-effort feature. There may still be some cases where it is not handled well.

George Burgess IV	18b28a86c1	Properly construct `inline` members without initializers ... Digging through commit logs, it appears the checks in this block predate `inline` class variables. With them, we fail to emit dynamic initializers for members that don't have an explicit initializer, and we won't go out of our way to instantiate the class denoted by `Var->getType()`. Fixes PR35599. llvm-svn: 327945	2018-03-20 03:27:44 +00:00
Richard Smith	93ee9caaed	In C++17, when instantiating an out-of-line definition of an inline static data ... member, don't forget to instantiate the initializer too. llvm-svn: 322236	2018-01-10 23:08:26 +00:00
Richard Smith	e124612eda	[c++17] Visit class template explicit specializations just like all other class definitions in codegen. ... If an explicit specialization has a static data member, it may be a definition and we may need to register it for emission. llvm-svn: 317296	2017-11-03 01:26:01 +00:00
Richard Smith	8910fe699e	For better compatibility with C++11 and C++14, emit a nondiscardable definition ... of a static constexpr data member if it's defined 'constexpr' out of line, not only if it's defined 'constexpr' in the class. llvm-svn: 316310	2017-10-23 03:58:34 +00:00
Richard Smith	d9b9009c61	PR28394: For compatibility with c++11 and c++14, if a static constexpr data ... member is redundantly redeclared outside the class definition in code built in c++17 mode, ensure we emit a non-discardable definition of the data member for c++11 and c++14 compilations to use. llvm-svn: 274416	2016-07-02 01:32:16 +00:00
Richard Smith	62f19e700d	Implement C++17 P0386R2, inline variables. (The 'inline' specifier gives a ... variable weak discardable linkage and partially-ordered initialization, and is implied for constexpr static data members.) llvm-svn: 273754	2016-06-25 00:15:56 +00:00
