Title: [armel] Atomic intrinsics are not implemented correctly Status in The GNU Compiler Collection: Fix Released Status in “gcc-4.4” package in Ubuntu: Fix Released Status in “glib2.0” package in Ubuntu: Fix Released Bug description: Binary package hint: gcc-4.4 Observed in gcc 4.4.2-3ubuntu1 Believed to affect all versions __sync_synchronnize() should perform a memory barrier, but is a noop (at least with -O2) __sync_lock_release() should place a memory barrier before the compare-exchange operation, but actually puts the barrier after, which may cause unsafe spinlock release Implications: packages built with unfixed gcc which use these intrinsics may not be multicore-safe on armel.
