  3. Call stack - Wikipedia

    en.wikipedia.org/wiki/Call_stack

    The call stack works well as a place for these parameters, especially since each call to a subroutine, which will have differing values for parameters, will be given separate space on the call stack for those values. In object-oriented languages such as C++, the list of parameters may also include the this pointer. Evaluation stack

  4. Stack (abstract data type) - Wikipedia

    en.wikipedia.org/wiki/Stack_(abstract_data_type)

    A number of programming languages are stack-oriented, meaning they define most basic operations (adding two numbers, printing a character) as taking their arguments from the stack, and placing any return values back on the stack. For example, PostScript has a return stack and an operand stack, and also has a graphics state stack and a ...

  5. Java bytecode - Wikipedia

    en.wikipedia.org/wiki/Java_bytecode

    Each frame for a method call has an "operand stack" and an array of "local variables". [5]: 2.6 [2] The operand stack is used for operands to computations and for receiving the return value of a called method, while local variables serve the same purpose as registers and are also used to pass method arguments. The maximum size of the operand ...

  6. Data segment - Wikipedia

    en.wikipedia.org/wiki/Data_segment

    The stack segment contains the call stack, a LIFO structure, typically located in the higher parts of memory. A "stack pointer" register tracks the top of the stack; it is adjusted each time a value is "pushed" onto the stack. The set of values pushed for one function call is termed a "stack frame". A stack frame consists at minimum of a return ...

    Where the previous value of the frame pointer is stored, which is used to restore the stack frame when the subroutine ends. Options include within the call stack, or in a specific register. Sometimes frame pointers are not used at all. [2]

  9. Tail call - Wikipedia

    en.wikipedia.org/wiki/Tail_call

    For example, in the Java virtual machine (JVM), tail-recursive calls can be eliminated (as this reuses the existing call stack), but general tail calls cannot be (as this changes the call stack). [13] [14] As a result, functional languages such as Scala that target the JVM can efficiently implement direct tail recursion, but not mutual tail ...
