* QTypeInfo: use C++11 type traits to deduce if a type is static or complexLars Knoll2018-12-101-4/+24
| | | | | | | | | | | | | | | | | | | All types that can be trivially copied and destructed are by definition relocatable, and we should apply those semantics when moving them in memory. Types that are trivial, are by definition not complex and should be treated as such. [ChangeLog][QtCore] Qt Containers and meta type system now use C++11 type traits (std::is_trivial, std::is_trivially_copyable and std::is_trivially_destructible) to detect the class of a type not explicitly set by Q_DECLARE_TYPEINFO. (Q_DECLARE_TYPEINFO is still needed for QList.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We fully specialize QTypeInfo for most C++ built-in types, but enums and extended integral types (like GCC's int128_t) were not covered. Now that we depend on <type_traits>, we can stop pessimizing enums and extended integral types in QVector and QVLA by defaulting QTypeInfo::isComplex to true for such types. Fix a test that checked that enums were complex types. This should have been a XFAIL test. Enums are not complex types.

* Remove qSwap specialization from Q_DECLARE_SHAREDMarc Mutz2015-01-101-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | The way swapping is supposed to work is: 1. Each type supplies a swap() function or function template in its namespace. Any good STL implementation will find it there through ADL. As will the primary qSwap() template. 2. Each use of swap() in Qt, in particular in template code, should use qSwap() instead of std::swap() or the using+swap-trick, because qSwap() automatically enables ADL. It also has a sophisticated conditional noexcept specification that can be used in the custom swap() functions' own noexcept clause. This change also allows us to convert implicitly-shared classes' member-swap functions to noexcept one at a time, because the specialization will no longer be in conflict with the primary template regarding exception specifications. The primary's specification could, of course, be reused here, but it's complex and if the machinery around it is changed later on, it will not affect Q_DECLARE_SHARED classes.
