32位汇编语言 在一段数组中找最大数 x86 汇编语言 asm文件 irvine32 intel 汇编语言

题目：

Create a procedure named FindLargest that receives two parameters: a pointer to a signed doubleword array, and a count of the array’s length. The procedure must return the value of the largest array member in EAX. Use the PROC directive with a parameter list when declaring the procedure. Preserve all registers(except EAX) that are modified by the procedure. Write a test program that calls FindLargest and passes three different arrays of different lengths. Besure to include negative values in your arrays. Create a PROTO declaration for FindLargest.
创建一个名为FindLargest的过程，该过程接收两个参数：指向有符号双字数组的指针和数组长度的计数。该过程必须返回EAX中最大数组成员的值。在声明过程时，将PROC指令与参数列表一起使用。保留由过程修改的所有寄存器（EAX除外）。编写一个测试程序，调用FindLargest并传递三个不同长度的数组。请确保在数组中包含负值。为FindLargest创建PROTO声明。
