| * qsimd_p.h: Don't set the __xxx__ variables with Clang and GCCThiago Macieira2017-06-121-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 418184c2a0ad97cce12717a43f84fa6f12ece189 set some extra defines that Clang and GCC do set so that MSVC and ICC builds would properly get the features detected. But that meant we set them with Clang and GCC (technically, set them again, but to the same value so no warning was printed). Don't do that. This commit allows me to use "-march=native -mno-rdrnd" to disable the unconditional use of RDRAND instruction. That's required to valgrind any applications, as the current version (3.12) does not have support for that instruction. vex amd64->IR: unhandled instruction bytes: 0x48 0xF 0xC7 0xF0 0x48 0x8B 0x55 0xE8 0x48 0x89 vex amd64->IR: REX=1 REX.W=1 REX.R=0 REX.X=0 REX.B=0 vex amd64->IR: VEX=0 VEX.L=0 VEX.nVVVV=0x0 ESC=0F vex amd64->IR: PFX.66=0 PFX.F2=0 PFX.F3=0 ==78321== valgrind: Unrecognised instruction at address 0x4ef159c. ==78321== at 0x4EF159C: _rdrand64_step (immintrin.h:208) ==78321== by 0x4EF159C: qt_random_cpu(void*, long long) (qrandom.cpp:95) Change-Id: Ia3e896da908f42939148fffd14c6884501de4fa4 Reviewed-by: Allan Sandfeld Jensen <allan.jensen@qt.io>

* | x86: Add detection of the AES and SHA New InstructionsThiago Macieira2017-02-211-1/+1
|/ | | | | | | | | | | | | | | | | | | The AES instructions were first introduced with the Westmere shrink (22nm) of the Nehalem architecture. The SHA instructions are still pending on Intel architecture, but is available on AMD family 17h (gcc argument -march=znver1). Both features operate on SSE registers, so that's why the MSVC command- line argument is the SSE2 one and the configure-time tests depend on features.sse2. The qmake feature names end in "ni" because "aes" and "sha" are too simple and could clash with other uses. The QT_COMPILER_SUPPORTS_ macro doesn't have the "NI" suffix because it has to match the GCC/Clang predefined macro.

Wrap this trick in template functions in qsimd_p.h. These are marked as always- inline and use __builtin_memcpy() where available in an attempt to avoid the memcpy() function call overhead in debug builds. While this looks prohibitively expensive, from the pov of the C++ abstract machine, it is 100% equivalent, except for the absence of undefined behavior. In one case, the cast produces a local temporary which is then copied into the function, and in the other case, that local variable comes from return value of qUnalignedLoad(). Consequently, GCC compiles these two versions into identical assembler code (only verfied for ucstrncmp, but there's no reason to believe that it wouldn't hold for the other cases, too).

* Reorganize the bits for the CPU feature detectionThiago Macieira2015-09-221-24/+36
| | | | | | | | | | | | | | | Instead of trying to detect one bit and set another, let's just use the bits from the x86 CPUID instruction on x86. This makes use of the full 64-bit space now. Since MSVC doesn't like enums bigger than 32-bit, we have to store the bit number instead of the actual bit value in the constant. For that reason, I also renamed the constants, to catch anyone who was using them directly, instead of through qCpuHasFeature.

* Update copyright headersJani Heikkinen2015-02-111-7/+7
| | | | | | | | | | | | | | | | | | Qt copyrights are now in The Qt Company, so we could update the source code headers accordingly. In the same go we should also fix the links to point to qt.io. Outdated header.LGPL removed (use header.LGPL21 instead) Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing combination. New header.LGPL-COMM taken in the use file which were using old header.LGPL3 (src/plugins/platforms/android/extract.cpp) Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license combination Change-Id: I6f49b819a8a20cc4f88b794a8f6726d975e8ffbe Reviewed-by: Matti Paaso <matti.paaso@theqtcompany.com>
* Store the GCC version number in Q_CC_GNUThiago Macieira2014-11-051-2/+2
| | | | | | | | | | | The sequence of (__GNUC__ * 100 + __GNUC_MINOR__) was used in quite a few places. Simplify it to make the code more readable. This follows the change done for Clang, which was quite necessary since Apple's version of Clang has different build numbers.
