| | | | | | | | | Since Qt 5.10, qTo/FromBig/LittleEndian<float/double> stopped working. It may be confusing, but big endian floats do exist, so not to break old code, we should support them.

* Add ++/--/min/max to QSpecialIntegerErik Verbruggen2018-08-171-0/+40
| | | | | | | | | | | | | Add both prefix and postfix versions of the increment/decrement operators, and a static constexpr min/max which returns the minimum/maximumm values that can be stored in the QSpecialInteger. These latter functions are useful to define constants, e.g.: typedef quint8_be IPv4_TTL; static constexpr TTL_TO_DROP = IPv4_TTL::min(); Change-Id: I825a279feb68b93572765a9fdb5aa7b06d1be35b Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Add qbswap for a memory regionThiago Macieira2018-07-041-0/+25
| | | | | | | | | | | | The compiler was generating some vectorized code for qresource.cpp but it wasn't very efficient. So improve upon it and make use in other places where we read UTF-16BE strings. [ChangeLog][QtCore] Added an overload of q{To,From}{Big,Little}Endian that operates on a memory region.

* doc: Add missing template textMartin Smith2017-12-041-1/+3
| | | | | | | | | | | | There are two fake classes in qendian.h that exist only documenting a lot of operator functions, but now that clang is being used to parse all C++ code, when a class is a template class, clangqdoc must see its template stuff to recognize template type T, for example. Hence, this update adds template<typename T> to some fake class declarations used only for documentation purposes. ie, inside #ifdef Q_CLANG_QDOC.

* Use the GCC and Clang __builtin_bswap intrinsics in qbswapThiago Macieira2014-12-201-13/+13
| | | | | | | | | | | | | | | | Glibc will use the intrinsics for 32- and 64-bit, but didn't for 16-bit (probably because GCC didn't document it until version 4.8), so this commit will make us access the intrinsics directly the intrisincs for all type sizes. Additionally, this will get us access to the compiler intrisics even without Glibc, such as when building against uclibc or Bionic. Another benefit is that both Clang and ICC will use the MOVBE instruction on Atom and Haswell architectures.

| | | | | | | | | | | | | | | | | | Just like qMalloc/qRealloc/qFree, there is absolutely no reason to wrap these functions just to avoid an include, except to pay for it with worse runtime performance. On OS X, on byte sizes from 50 up to 1000, calling memset directly is 28-15% faster(!) than adding an additional call to qMemSet. The advantage on sizes above that is unmeasurable. For qMemCopy, the benefits are a little more modest: 16-7%.
