The BR2_ARCH_HAS_ATOMICS was added because on ARC, atomic instructions may not be provided by the architecture and therefore the compiler does not provide the __sync_*() built-ins. However, since then, icu was changed and is now able to use C++11 atomics, or even no atomic operations at all. In fact, icu will: * If possible, it will use C++11 atomics, which internally rely on the __atomic built-ins. These are available since gcc 4.7, and all architectures provide it. On some architectures, you *must* link with libatomic, on some other architectures, they are available built-in, but in all cases, linking against libatomic does not harm. Thanks to this, even ARC with no atomic support (which was the original reason for adding the BR2_ARCH_HAS_ATOMICS) dependency builds fine, provided -latomic is added to LIBS. * If C++11 atomics are not available, then it falls back to __sync_*() built-ins, which allows compilers older than 4.7 to be supported. * If really no atomic mechanism is available, then it falls back to a basic implementation based on a mutex. Conclusion: - The BR2_ARCH_HAS_ATOMICS dependency is no longer needed. - We need to link with -latomic when gcc >= 4.7 is used. Note that reverse dependencies of icu are also changed accordingly.

Configure options allow to set which modules are being

compiled or not in Qt, but Qt also provide a more

enabled or disabled, through a header file. Examples of such

header files can be found in src/corelib/global/qconfig-*.h

in the Qt sources.
