* Add AArch64 ASM to qimage_neon.cppAllan Sandfeld Jensen2015-11-261-2/+1
| | | | | | | | | | | Since AArch64 NEON assembly is different from Arm32 NEON we need to write a separate version. Assembly is used over intrinsics as the intrinsics have trouble efficiently using the vstX and vldX instructions.

* Fix memory leak in QJpegHandlerPrivateJian Liang2015-07-061-2/+3
| | | | | | | | | | | | | | | Since the introduction of jpeg auto transform, it is possible to read jpeg header after its state was changed from ReadHeaer to Ready which will lead to creating some resources again without releasing them. For example, if you call QImageReader::setAutoTransform(true) and then call QImageReader::read(), QJpegHandlerPrivate::readJpegHeader() will be called twice and it will allocate resource again without releasing the old one. This patch add a new state ReadingEnd to prevent the header from being read twice.

* 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.
