堆栈转换行为顺序如下:The stack transitional behavior, in sequential order, is:

  1. 存储在本地变量中指定索引处的地址被推送到堆栈上。The address stored in the local variable at the specified index is pushed onto the stack.

@No__t-0 指令将传递的索引处的局部变量号的地址推送到堆栈上,其中局部变量从0开始编号。The ldloca.s instruction pushes the address of the local variable number at the passed index onto the stack, where local variables are numbered 0 onwards. 在堆栈上推送的值已正确对齐,以便与 Ldind_IStind_I 之类的指令一起使用。The value pushed on the stack is already aligned correctly for use with instructions like Ldind_I and Stind_I. 结果为暂时性指针(类型 *)。The result is a transient pointer (type *).

@No__t-0 指令提供了一个有效的编码,可与局部变量0到255一起使用。The ldloca.s instruction provides an efficient encoding for use with the local variables 0 through 255.

以下 @no__t 0 方法重载可以使用 @no__t 操作码:The following Emit method overload can use the ldloca.s opcode:
