[Bug 664431] Re: QT on armel is built with NEON by default

[Thiago Macieira]

That's already so:

$ git ls-files *_neon*                       
src/gui/image/qimage_neon.cpp
src/gui/painting/qdrawhelper_neon.cpp
src/gui/painting/qdrawhelper_neon_asm.S
src/gui/painting/qdrawhelper_neon_p.h

These files are the ones that contain 99% of the Neon code in Qt and
they're properly run-time detected now (as far as I know).

The only unprotected code is in qstring.cpp: the cost of runtime
detection is higher than the benefit, so we decided not to do it. If you
compile Qt for a processor with Neon, you get it, otherwise you don't.
