Hi there. I've been looking into updating the QT4 atomic operations as an alternative to working around it in GCC. There's ARM specific code in: http://qt.gitorious.org/qt/qt/blobs/4.7/src/corelib/arch/qatomic_armv6.h that should be updated to include IT instructions so that it can compile in Thumb-2 mode.
There are bigger problems here though: * There's code in corelib/arch/armv6/qatomic*.c that may also being used * qatomic_armv6.h includes code for RVCT which should be updated for Thumb-2 by someone * The code may not work on multi-processor systems like Panda due to the lack of DMB instructions The better fix would be to replace everything with __sync_* primitives similar to qatomic_avr32.h and require GCC 4.4 or higher. The same probably applies to glib. Thoughts? Any volunteers? It's mildly outside the Toolchain WG's mandate.
