distro default optimization flags, to query for your OS/arch,
rpm --eval "%{optflags}"
The output is:
-O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions
-fstack-protector --param=ssp-buffer-size=4 -m32 -march=i686 -mtune=atom
-fasynchronous-unwind-tables
What exactly does this mean? As far as I know, the VM shouldn't have
anything to do with Atom processor.
uname -a gives:
Linux nutan 2.6.32-358.el6.i686 #1 SMP Thu Feb 21 21:50:49 UTC 2013 i686
i686 i386 GNU/Linux
As suggested by Thiago Macieira of Qt-Interest, I ran
qmake -d -d 2>&1 | grep atom > output
The output is attached. 'atom' came from /usr/lib/qt4/mkspecs/default/qmake.conf.
