* Minor improvements in qrgba64_p.hAllan Sandfeld Jensen2020-10-311-31/+104
| | | | | | | | | | Adds SIMD acceleration for the blend_pixel, and raw interpolate methods, and cleans up other SIMD code. Gives minor speedups in text rendering and various fallbacks. Change-Id: Ib0ad8b408450e4e73f3c1d50e9caaed0098acb94 Reviewed-by: Thiago Macieira <thiago.macieira@intel.com>
* Replace Q_ALWAYS_INLINE with static inlineAllan Sandfeld Jensen2020-07-281-21/+19
| | | | | | | | | Static inline on functions serves the same purpose of keeping non- inlined instances from different binaries from being mixed, and has the benefit of being available across compilers.

* Add qtguiglobal.h and qtguiglobal_p.hLars Knoll2016-07-031-0/+1
| | | | | | | | | | | | | | | | | | | | The new modular configuration system requires one global header per module, that is included by all other files in this module. A similar scheme and naming convention is already being used for many other modules (e.g. printsupport, qml, quick). That header will later on #include the configuration file for Qt Gui. For now it defines the Q_GUI_EXPORT macro for this library. In addition, add a private global header, qtguiglobal_p.h, that can later on include the private config header for Qt Gui for things we don't want to export to the world.

* ARM: Vectorize common QRgba64 compositing functions.Erik Verbruggen2016-05-241-17/+83
| | | | | | | | | | | | | | | | Adds overloaded functions for some common operations used for compositing, and use those together with specialized loading/storing. QRgba64 is represented as a quint64, so most of the time it lives in the integer registers. By overloading functions to return SIMD data types, the temporary values are kept in SIMD registers (so no more unnecessary transfers between the registers, which can cost a lot on ARM). It also allows the compiler to do better TBAA and optimizations. Another benefit is that the loop bodies are smaller, giving them a higher chance to fit in the micro-op cache of modern CPUs.

* Solid and gradients in high color accuracyAllan Sandfeld Jensen2015-04-101-0/+83
This patch updates the internal color precisions of solids and gradients to 16bit per color. This makes it possible to render at higher precision on non-premultiplied ARGB32, the RGB30 formats and any other hi-color formats if more are added. [ChangeLog][QtGui][Painting] Internal precision of solids and gradients is now up to 16bit per color.
