[Development] 'register' not fully removed from Qt?

[Jiergir Ogoerg]

Hi,
Judging by this:

https://codereview.qt-project.org/#change,59022

the 'register' keyword has been removed from Qt,
but I have a Qt 5.2 build from Dec 22 2013 on
amd64 Linux and LLVM 3.4 issues a pile of warnings about
the 'register' keyword in QtCore/qendian.h like this:

In file included from
${HOME}/apps/Qt5.2.0/5.2.0/gcc_64/include/QtCore/QtCore:13:
${HOME}/apps/Qt5.2.0/5.2.0/gcc_64/include/QtCore/qendian.h:294:12: warning:
      'register' storage class specifier is deprecated [-Wdeprecated]
    return bswap_32(source);


So was 'register' reintroduced or not fully removed, or something else?
