Author: rnk Date: Tue Mar 1 19:21:48 2016 New Revision: 262442 URL: http://llvm.org/viewvc/llvm-project?rev=262442&view=rev Log: Add a few dllimport/dllexport tests. NFC
Summary: This change just adds tests for some corner cases of dllimport/dllexport, primarily for some static methods. We plan to enable dllimport/dllexport support for the PS4, and these additional tests are for points we previously were testing internally. -Warren Ristow SN Systems - Sony Computer Entertainment Group Reviewers: rnk Subscribers: silvas Differential Revision: http://reviews.llvm.org/D17775 Modified: cfe/trunk/test/CodeGenCXX/dllexport.cpp cfe/trunk/test/CodeGenCXX/dllimport.cpp Modified: cfe/trunk/test/CodeGenCXX/dllexport.cpp URL: http://llvm.org/viewvc/llvm-project/cfe/trunk/test/CodeGenCXX/dllexport.cpp?rev=262442&r1=262441&r2=262442&view=diff ============================================================================== --- cfe/trunk/test/CodeGenCXX/dllexport.cpp (original) +++ cfe/trunk/test/CodeGenCXX/dllexport.cpp Tue Mar 1 19:21:48 2016 @@ -570,6 +570,30 @@ struct __declspec(dllexport) T { USEVAR(T::b) int T::c; +// Export template class with static member variable +// MSC-DAG: @"\01?StaticClassVarExpTmplClass@?$TmplClass@H@@2HA" = weak_odr dllexport global i32 0, comdat, align 4 +// GNU-DAG: @_ZN9TmplClassIiE26StaticClassVarExpTmplClassE = weak_odr dllexport global i32 0, comdat, align 4 +template<typename T> +struct __declspec(dllexport) TmplClass +{ + static T StaticClassVarExpTmplClass; +}; + +template<typename T> +T TmplClass<T>::StaticClassVarExpTmplClass; + +// Export a definition of a template function. +// MSC-DAG: define weak_odr dllexport i32 @"\01??$TypeFunTmpl@H@@YAHH@Z" +// GNU-DAG: define weak_odr dllexport i32 @_Z11TypeFunTmplIiET_S0_ +template<typename T> +T __declspec(dllexport) TypeFunTmpl(T t) { return t + t; } + +// Instantiate the exported template class and the exported template function. +int useExportedTmplStaticAndFun() +{ + return TmplClass<int>::StaticClassVarExpTmplClass + TypeFunTmpl<int>(10); +} + template <typename T> struct __declspec(dllexport) U { void foo() {} }; struct __declspec(dllexport) V : public U<int> { }; // U<int>'s assignment operator is emitted.
