Subject: c++: add noexcept specifiers to compiler optimize aggresively.
X-Git-Tag: submit/tizen_3.0/20161121.043705^2~3
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=e7fcecfbbd7cbb985cc2ff01676686afc30d2c0e;p=platform%2Fcore%2Fuifw%2Fui-viewmgr.git

c++: add noexcept specifiers to compiler optimize aggresively.

We don't need to throw exceptions becaus we have own exception specification (tizen error values).
This noexcept keyword may help compiler to optmize op code better.
