[Development] Disabling thread safe static guards
Hi, Can we disable gcc's feature of emitting extra code to make local static initialization thread safe ? (-fno-threadsafe-statics) Since MSVC doesn't support it we can't rely on this feature in cross-platform Qt code (maybe only in QPA code). Generates uneeded code and helps hidding crashes that developers using Linux don't notice.

Generates uneeded code and helps hidding crashes that developers using Linux don't notice. The code is needed because we use it in Q_GLOBAL_STATIC. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center ___ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development

Also, it's one of the C++11 features. It's tracked as Q_COMPILER_THREADSAFE_STATICS and is supported in MSVC since 2015. -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center ___ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
