gcc-4.9: backport from gcc trunk r212178
When compiling meta-toolchain-qt5 on cortexa8, the compiler throws an internal compiler error: ... qttools-opensource-src-5.3.2/src/linguist/shared/po.cpp: In function 'bool loadPO(Translator&, QIODevice&, ConversionData&)': qttools-opensource-src-5.3.2/src/linguist/shared/po.cpp:717:1: internal compiler error: in add_stores, at var-tracking.c:6000 ... Tracking this down led to https://bugs.linaro.org/show_bug.cgi?id=534 It seems the bug is well know and fixed upstream. So backporting from trunk seems to be the right solution. This fixes the compiler problem on cortexa8 and does not seem to be very invasive.
