* Add AVX2 autovectorized versions of premultiplyAllan Sandfeld Jensen2015-03-101-65/+20
| | | | | | | | | | | | Following up on using GCC's autovectorizing for faster SSE4.1 premultiply, this patch adds specialized autovectorized versions of premultiply for AVX2, giving another almost doubling in speed. To make the speed up for AVX2 and also SSE4_1 available to non-GCC compilers, the target-specific methods have been moved to separate files.

Since the last two commits, there's no runtime detection of either SSE2 or Neon support, so there's no point in attempting runtime detection.

* | Remove runtime detection of Neon on ARM CPUsThiago Macieira2014-01-161-29/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | Now the only way to enable Neon support is to change the mkspec. [ChangeLog][Important Behavior Changes] Qt no longer checks for support for the Neon FPU on ARM platforms at runtime. Code optimized for Neon must be enabled unconditionally at compile time by ensuring the compiler supports Neon. You may need to edit your mkspec for that.

* | Remove runtime detection of SSE2Thiago Macieira2014-01-161-63/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the compiler supports SSE2, we'll use our SSE2-optimised code unconditionally. Runtime detection is left for SSSE3 code. The SSE2 codebase is big and thus a timebomb if an inline function gets leaked out and run without runtime check. In reality, it's extremely unlikely people running CPUs without SSE2 support are running Qt 5 at this moment (they're either too old or too new, e.g. Intel Quark). The SSSE3 codebase is a lot more manageable.

* | Remove the files building AVX codeThiago Macieira2013-12-101-70/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This feature was never completely implemented. Sure, it's nice to build the SSE2 + SSSE3 code with the VEX prefix, which results in better code. But the leap isn't that big anyway. This is the first step to removing the runtime detection for the drawhelpers. They create timebombs when we use inline functions.
