In practice this is easy; just don't write code that does low-level manipulations of the stack frame or makes assumptions about the stack layout.
它使用堆栈体系结构，这意味着在使用指令操作数之前要先将它们装入内部堆栈。
It USES a stack architecture, meaning instruction operands are loaded to an internal stack before they're used.
字节码使用一个理论上无限大的操作数堆栈来描述计算。
Bytecodes describe calculations using a theoretically infinitely large operand stack.

This operational capability makes ILOG JRules another key component in the software stack, providing the capability to execute the appropriate business processes based on observed events.
把这个操作符压入(push)堆栈。
因为y是在输出操作数部分中指定的，所以 %edx中更新的值存储在-8(%ebp)，堆栈上 y 的位置中。
Since y is specified in the output operand section, the updated value in %edx is stored in -8(%ebp), the location of y on stack.
可将callcc 视为使用continuation对象中的调用堆栈替换当前堆栈的操作。
Think of the callcc as replacing the current call stack with the call stack in the continuation object.
