Instruction Combining

At the source code level, combine two statements into one statement. At the IL 
(Intermediate Language) level, combine two instructions into one instruction.

Example:

In the code fragment below, the two post-increment statements can be combined 
into one statement.

int i;

void f (void)
{
  i++;
  i++;
}

The code fragment below shows the function after the two post-increment 
statements have been combined into one statement.

int i;

void f (void)
{
  i += 2;
}
