* MIPS: Support recognition of the DSP ASE at run-timeAdrian Perez de Castro2014-06-271-1/+3
| | | | | | | | | | | | | Add detection of MIPS DSPr2 at run-time in qsimd.cpp. This makes it possible to have generic Qt builds for MIPS that can enable the fast code paths for processors with the DSP ASE at run-time. Also, this makes it possible to manually disable them by setting the environment variable "QT_NO_CPU_FEATURE=dspr2". Last, but not least, functions requiring DSPr2 are not enabled when running in CPUs with version-1 DSP.

* | MIPS: Fast path for rgb888 to rgb32 conversionAdrian Perez de Castro2014-03-061-0/+4
|/ | | | | | | | | | Add a hand-coded MIPS assembler function to convert a stream of rgb888 bytes to an array of 32-bit ARGB values. This is used in QImage for image conversion, and also in QJpegHandler for decoding JPEG image scanlines.

* Remove runtime detection of Neon on ARM CPUsThiago Macieira2014-01-161-1/+1
| | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | 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.

Note: the functions need to be declared outside of the function block so namespace scoping works properly with MSVC. For functions declared inside, it expects them to be in the global namespace.

Needed a cast to lose the volatile again, passing the argument to qMin().

* Make the CPU detection much more efficient in user codeThiago Macieira2012-07-021-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | First, check that the option in question hasn't been already enabled by the compiler, via compiler switches. If it has been, then we don't need to verify anything, and we can assume that it's safe to use such instructions. For example, on an x86-64 build, qCpuHasFeature(SSE2) is always a constant true. If the compile-time check fails, then we proceed to try and detect the processor features at runtime. But instead of insisting on a call to qDetectCPUFeatures, allow the code using the detection to read from a variable and simply test it for values. Only if the variable isn't initialised should it make a function call. The Q_ASSUME allows this code to be very efficient even with multiple uses of qCpuHasFeature. Change the uninitialised value from -1 to 0 so that simpler instructions can be used to check for non-initialisation. The qDetectCPUFeatures function is renamed to qDetectCpuFeatures to match the Qt coding style and also to catch uses this code that need to be adapted.

* Overhaul the qsimd_p.h: rename macros and update conditionalsThiago Macieira2012-05-311-4/+4
| | | | | | | | | | | | | | | The QT_HAVE_xxx macros are replaced with QT_COMPILER_SUPPORTS_xxx. They indicate that the compiler supports those intrinsics, but not necessarily that they can be used right now. ICC and MSVC allow one to use the intrinsics anywhere, but for Qt all uses of the intrinsics are either in specially-built files, protected by runtime checks, or they are unconditional (qstring.cpp). So we only use the intrinsics when the compiler was instructed to generate code for that instruction set anyway.

* Support more scaling factors for JPEG decompressionJohn Brooks2012-04-121-19/+24
| | | | | | | | | | | | | | | | | Since libjpeg 7, decompression scaling factors of [1,16]/8 have been supported. Upscaling is slower, but using the entire range of downscaling factors is significantly faster for sizes between the power-of-two factors. Time to decompress a 5184x3456 image and scale to 1900x1200, slightly less than 3/8ths, changes from 251ms to 203ms. libjpeg versions prior to 7 will round up to the next largest factor they support, and continue to work as before.
