*	Centralize the x86 SIMD testing in one place	Thiago Macieira	2017-11-30	1	-3/+0
\| \| \| \| \| \| \| \|	Since the x86_simd/main.cpp file already has all the source for each and every test anyway, just reuse it. Change-Id: I938b024e38bf4aac9154fffd14f779f450827fb9 Reviewed-by: Oswald Buddenhagen <oswald.buddenhagen@qt.io>
*	x86: Add detection of the AES and SHA New Instructions	Thiago Macieira	2017-02-21	1	-0/+3
	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.
