It would be a very simple question (could be duplicated), but I was unable to find it.
Win32 API provides a very开发者_StackOverflow handy set of atomic operations (as intrinsics) such as InterlockedIncrement
which emits lock add
x86 code. Also, InterlockedCompareExchange
is mapped to lock cmpxchg
.
But, I want to do that in Linux with gcc. Since I'm working 64-bit, it's impossible to use inline assembly. Are there intrinsics for gcc?
