I had implemented a LIFO for shared memory context using assembly for ARMv8 64bit. The LIFO inserts a node in beginning and each node structure's fir ...
I found a couple of places online which state that CLREX "must" be called whenever an interrupt routine is entered, which I don't understand. The docs ...
What' s the advantage of LL/SC comparing with CAS(compare and swap) in computer architecture? I think LL/SC can case livelock in many-core system, and ...
