Many modern high level languages like Java/ C# have locks/ monitors as
language level features. Hardwares typically have lower level
synchronization primitives like CAS. One can implement a spinlock
using CAS, but it is bad for performance as it busy-waits for the lock
to be released. Can anyone tell me how these locks/monitors are
typically and efficiently compiled? Can you cite any paper on this?


Thanks in advance,
Arnab
