Everything that applied to Qt 4 still applies to Qt 5. What did change is that I improved that support a bit in Qt 5, added Windows- MSVC support (see [1]) and cleaned up the older SIMD, like MMX. I have also a huge patch of pending changes to improve even further, but I haven't managed to fix some "WIP" that have been there for over a year. There are now some pending patches I'm reviewing that improve SIMD support on MIPS.
