Assembly language for x86 Processors Create a procedure named FindLargest that receives two parameters: a pointer to a signed doubleword array and 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.

Question
Assembly language for x86 Processors
Create a procedure named FindLargest that receives two parameters: a pointer to a signed doubleword array and 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 lengths. Be sure to include negative values in your arrays. Create a PROTO declaration for FindLargest.
