Initial import from the monolithic Qt. This is the beginning of revision history for this module. If you want to look at revision history older than this, please refer to the Qt Git wiki for how to use Git history grafting. At the time of writing, this wiki is located here: http://qt.gitorious.org/qt/pages/GitIntroductionWithQt If you have already performed the grafting and you don't see any history beyond this commit, try running "git log" with the "--follow" argument. Branched from the monolithic repo, Qt master branch, at commit 896db169ea224deb96c59ce8af800d019de63f12 2011-04-27 10:05:43 +00:00			`SOURCES = sse3.cpp`
Add configure-time checking for the SSE and AVX features on Windows Modify configure.exe to run some configure-time tests and check if the SSE and AVX compiler features are supported. The tests themselves required a bit of changes to compile with MSVC. The include in sse4_2.cpp was wrong. And for whatever reason, it didn't like the volatile variables, which GCC, Clang and ICC have been happy with. This should produce no effect in compilation, though: even dead code must be syntactically correct. We're not running the output.

Silence cl.exe warning about -arch:SSE2 being unknown in 64-bit builds That implies we need to differentiate between a variable set but empty and an empty variable. GCC, Clang and the Intel compiler accept -msse2 on 64-bit builds without warning (they also accept -mno-sse2), but the Microsoft compiler does not have that option.

Move the SSE2/AVX/Neon/etc. flags into the compiler mkspecs This allows us to have different flags for the compilers for supporting the same feature. For example, the official flag in GCC to support AVX2 is -mavx2, but ICC does not support it (yet), requiring -march=core-avx2 or -xCORE-AVX2. That flag, instead, enables support for all the features that the "Core-AVX2" processor (codename Haswell) will support. And clearly, the MSVC flags are different.
