* | qsimd: add support for new x86 CPU featuresThiago Macieira2018-05-054-328/+393
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds detection for: VAES, GFNI, AVX512VBMI2, AVX512VNNI, AVX512BITALG, AVX512VPOPCNTDQ, AVX512_4NNIW, AVX512_4FMAPS. These features were found in the "Intel® Architecture Instruction Set Extensions and Future Features" manual, revision 30. This commit also adds support for RDPID (already in the main manual) and the Control-flow Enforcement Technology, which appears in a separate Intel paper. This new support was done by adding a new generator script so we don't have to maintain two tables in sync, one in qsimd.cpp with the feature names, and the other in qsimd_p.h. Since we now need a lot more bits, it's no longer worth keeping the two halves of the qt_cpu_features variable mostly similar to the main two CPUID results. This commit goes back to keeping things in order, like we used to prior to commit 6a8251a89b6a61258498f4af1ba7b3d5b7f7096c (Qt 5.6) At the time of this commit, GCC 8 has macros for AVX512VPOPCNTDQ, AVX512_4NNIW, AVX512_4FMAPS, AVX512VBMI2 and GFNI.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The problem is that qCountLeadingZeroBits is calling qPopulationCount which is only conditionally constexpr, so qCountLeadingZeroBits can only be marked constexpr if qPopulationCount is also.

(which is not constexpr, but it works because the compiler is not forced to diagnose the problem because of the "?:" operator.

I thought of two ways of fixing this, one was calling QLocalePrivate::updateSystemPrivatea() from the QAndroidSystemLocale constructor, but giving the responsibility to not break things to the plugin seems a little fragile, so making the check on QLocale() seems better. Without this patch an Android app doing QApplication app(argc, argv); qDebug() << QLocale().name(); qDebug() << QLocale().name(); qDebug() << QLocale::system().name(); qDebug() << QLocale().name(); would print "" "" "ca_ES" "ca_ES" now it correctly prints "ca_ES" the four times.
