Comment 12 for bug 675347

Your QT build must be picking up the wrong compiler:

mavis% g++-4.5 -O2 -save-temps -mfpu=neon -c atomic.cc
atomic.cc: In function 'int foo(QBasicAtomicInt&)':
atomic.cc:25:35: error: output number 2 not directly addressable
atomic.cc:25:35: warning: use of memory input without lvalue in asm operand 4 is deprecated
mavis% g++-4.5 -O2 -save-temps -mfpu=neon -c atomic.cc -fno-strict-volatile-bitfields
mavis% g++-4.5 --version
g++-4.5 (Ubuntu/Linaro 4.5.1-10ubuntu1) 4.5.2

Can you please double-check?

BTW, for me g++ refers to a 4.4 compiler:

mavis% g++ --version
g++ (Ubuntu/Linaro 4.4.4-14ubuntu5) 4.4.5

mavis% g++ -O2 -save-temps -mfpu=neon -c atomic.cc -fno-strict-volatile-bitfields
cc1plus: error: unrecognized command line option "-fno-strict-volatile-bitfields"
