Code that works fine-until you turn optimization on Code that works fine-as long as interrupts are disabled Flaky hardware drivers Tasks that work fine in isolation-yet crash when another task is enabled If you answered yes to any of the above, it's likely that you didn't use the C keyword volatile.
Syntax To declare a variable volatile, include the keyword volatile before or after the data type in the variable definition.
For instance both of these declarations will declare foo to be a volatile integer: volatile int foo; int volatile foo; Now, it turns out that pointers to volatile variables are very common.
Use A variable should be declared volatile whenever its value could change unexpectedly. In practice, only three types of variables could change: Memory-mapped peripheral registers Global variables modified by an interrupt service routine Global variables within a multi-threaded application Peripheral registers Embedded systems contain real hardware, usually with sophisticated peripherals.
Interrupt service routines Interrupt service routines often set variables that are tested in main line code. Multi-threaded applications Despite the presence of queues, pipes, and other scheduler-aware communications mechanisms in real-time operating systems, it is still fairly common for two tasks to exchange information via a shared memory location that is, a global.

The following C programs, and accompanying assemblies, demonstrate how the volatile keyword affects the compiler's output.
The compiler in this case was GCC. While observing the assembly code, it is clearly visible that the code generated with volatile objects is more verbose, making it longer so the nature of volatile objects can be fulfilled.
The volatile keyword prevents the compiler from performing optimization on code involving volatile objects, thus ensuring that each volatile variable assignment and read has a corresponding memory access.
Without the volatile keyword, the compiler knows a variable does not need to be reread from memory at each use, because there should not be any writes to its memory location from any other thread or process.
The Java programming language also has the volatile keyword, but it is used for a somewhat different purpose.
When applied to a field, the Java qualifier volatile provides the following guarantees:. Using volatile may be faster than a lock , but it will not work in some situations before Java 5 .
The range of situations in which volatile is effective was expanded in Java 5; in particular, double-checked locking now works correctly. In C , volatile ensures that code accessing the field is not subject to some thread-unsafe optimizations that may be performed by the compiler, the CLR, or by hardware.
When a field is marked volatile , the compiler is instructed to generate a "memory barrier" or "fence" around it, which prevents instruction reordering or caching tied to the field.
When reading a volatile field, the compiler generates an acquire-fence , which prevents other reads and writes to the field, including those in other threads, from being moved before the fence.
When writing to a volatile field, the compiler generates a release-fence ; this fence prevents other reads and writes to the field from being moved after the fence.
Using the volatile keyword does not support fields that are passed by reference or captured local variables ; in these cases, Thread.
VolatileRead and Thread. VolatileWrite must be used instead. The guarantees provided by Thread. VolatileWrite are a superset of the guarantees provided by the volatile keyword: instead of generating a "half fence" ie an acquire-fence only prevents instruction reordering and caching that comes before it , VolatileRead and VolatileWrite generate a "full fence" which prevent instruction reordering and caching of that field in both directions.
The Thread. VolatileWrite methods generate a full fence by calling the Thread. MemoryBarrier method, which constructs a memory barrier that works in both directions.
In addition to the motivations for using a full fence given above, one potential problem with the volatile keyword that is solved by using a full fence generated by Thread.
MemoryBarrier is as follows: due to the asymmetric nature of half fences, a volatile field with a write instruction followed by a read instruction may still have the execution order swapped by the compiler.
Because full fences are symmetric, this is not a problem when using Thread. Making all variables volatile in a function is also useful finding aliasing related bugs.
This makes visible to other threads actions done in this thread, and vice versa. From Wikipedia, the free encyclopedia. LC0 xor eax , eax call printf xor eax , eax add rsp , 8.

Peripheral registers. Embedded systems contain real hardware, usually with sophisticated peripherals. These peripherals contain registers whose values may change asynchronously to the program flow.
As a very simple example, consider an 8-bit status register at address 0x It is required that you poll the status register until it becomes non-zero.
The nave and incorrect implementation is as follows:. This will almost certainly fail as soon as you turn the optimizer on, since the compiler will generate assembly language that looks something like this:.
The rationale of the optimizer is quite simple: having already read the variable's value into the accumulator on the second line , there is no need to reread it, since the value will always be the same.
Thus, in the third line, we end up with an infinite loop. To force the compiler to do what we want, we modify the declaration to:.
Subtler problems tend to arise with registers that have special properties. For instance, a lot of peripherals contain registers that are cleared simply by reading them.
Extra or fewer reads than you are intending can cause quite unexpected results in these cases. Interrupt service routines.
Interrupt service routines often set variables that are tested in main line code. For example, a serial port interrupt may test each received character to see if it is an ETX character presumably signifying the end of a message.
An incorrect implementation of this might be:. With optimization turned off, this code might work. As far as the compiler is concerned, the expression!
Consequently, all the code after the while loop may simply be removed by the optimizer. If you are lucky, your compiler will warn you about this.
If you are unlucky or you haven't yet learned to take compiler warnings seriously , your code will fail miserably. Then all of your problems well, some of them anyway will disappear.
Multi-threaded applications. Despite the presence of queues, pipes, and other scheduler-aware communications mechanisms in real-time operating systems, it is still fairly common for two tasks to exchange information via a shared memory location that is, a global.
When you add a pre-emptive scheduler to your code, your compiler still has no idea what a context switch is or when one might occur.
Thus, another task modifying a shared global is conceptually identical to the problem of interrupt service routines discussed previously. So all shared global variables should be declared volatile.
For example:. This code will likely fail once the compiler's optimizer is enabled. Declaring cntr to be volatile is the proper way to solve the problem.
Final thoughts. Some compilers allow you to implicitly declare all variables as volatile. Resist this temptation, since it is essentially a substitute for thought.
It also leads to potentially less efficient code. Also, resist the temptation to blame the optimizer or turn it off.
