I have implemented a lock free queue in C using compare and swap based on http://www.boyet.com/articles/LockfreeQueue.html.
Is the following comparison an atomic action?开发者_StackOverflow社区 I.e., can it be reduced to a single CPU instruction?
In the Cortex-M3 instruction set, there exist a family of LDREX/STREX instructions such that if a location is read with an LDREX instruction, a following STREX instruction can write开发者_运维技巧 to

In this program: int x, y; int *old = &x; int *new = &y; int * volatile cur = &x; OSAtomicCompareAndSwapPtrBarrier(old, new, &cur);
I am writing a program which has one process reading and writing to a shared memory and another process only reading it. In the shared memory there is a struct like this:
