In general the product should move forward and drop work-arounds like -mimplicit-it. We (the greater ARM community) should fix these package problems as they are found. Here's a bunch of quick-fire statements: * Qt is currently broken on ARM multiprocessor systems * Qt provides a QAtomic class

Hi Richard, Recapping on this earlier conversation: http://lists.linaro.org/pipermail/linaro-toolchain/2010-July/30.html http://lists.linaro.org/pipermail/linaro-toolchain/2010-July/35.html Is it worth another attempt to make a case to upstream for supporting passing -mimplicit-it=thumb
