GlobalVariable 是LLVM IR 中的一个类,代表全局变量。全局变量是在整个程序执行期间都存在的变量,它们在程序开始执行时被初始化,并且在程序结束时销毁。 数组字面值是一种在代码中直接定义数组初始值的方式,例如在 C/C++ 中使用花括号 {} 来初始化数组。 相关优势 平台无关性:LLVM IR 的设计使得它可以在不同的...

Explanation of (1): When you refer to a variable via its name, the initial result is a so-called reference, a data structure with two main fields: base points to the environment, the data structure in which the variable’s value is stored. referencedName is the name of the variable....
SQL Server provides a massive number of global variables, which are very effective to use in our regular Transact-SQL. Global variables represent a special type of variable. The server always maintain the values of these variables. All the global variables represent information specific to the serv...
