* Remove the mandatory x86-64 features from its feature listThiago Macieira2023-05-311-3/+3
| | | | | | | | | | | | | | The x86-64 architecture mandates support for MMX and SSE2, so we don't need to tell that the compiler generates them. They're implied. This could serve to determine that the user specified no -march= or -m flags that affect the architecture on the CMAKE_CXX_FLAGS, but fails if the compiler does that on its own for this particular target. For example, both for Android and macOS, the minimum feature set is SSSE3 for 32-bit and SSE4.1 for 64-bit.

| | | | | | | | | | | | Adds runtime CPU detection for Windows and macOS, and switches feature detection of AES to runtime like for x86, So far only on ARM64, since gcc doesn't do function versioning on ARM32, but clang can, so it could be added later.

* SIMD: Remove unused (and unlikely to be ever used) AVX-512 profilesThiago Macieira2018-06-251-5/+5
| | | | | | | | | | | | | "AVX512MIC" (Many Integrated Cores) is the set of AVX-512 features found on the Intel Xeon Phi coprocessors (codename "Knights Landing"), which is an unlikely architecture for Qt to run on. The two profiles with VL came from study of early GCC code and are no longer applicable. GCC source code now shows both VBMI and IFMA as part of the -march=cannonlake feature set.

* qsimd: add support for new x86 CPU featuresThiago Macieira2018-05-051-1/+33
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Remove -arch argument and #define QT_ARCH from configuresBradley T. Hughes2012-03-131-0/+70
Do not try to detect the host or target architectures using uname or similar, and do not override with the -arch or -host-arch configure arguments. The configures will still accept the -arch and -host-arch arguments, but it ignores them and instead outputs a warning stating that these arguments are obsolete and should not be used. Set QT_ARCH and QT_HOST_ARCH qconfig.pri variables based on the compiler target. This is done by running qmake (twice when cross-compiling) on config.tests/arch/arch.pro, which preprocesses a file that contains all knowns processors. On Windows, configure.exe has never run any config.tests before, and does not currently have a function to run a program and capture its output. Use _popen() to accomplish this (as qmake does for its system() function). This needs to be done after qmake is built, as does the mkspecs/qconfig.pri generation. As a side effect, the configure steps have been slightly re-ordered, but the overall result is the same. The displayConfig() call is moved to just before generating Makefiles, so that it can show the detected architecture(s).
