concatenate two bytes char byte1 and char byte2 into a single short

Question

I want to concatenate two bytes char byte1 and char byte2 into a single short in Assembly.

How can I do it? Using shifts?

I'm working with IA32

Answer 1

I just solved the problem and did this in case somebody has the same problem:

concatBytes.s :

 .section .data

.global byte1
.global byte2

.section .text
.global concatBytes


concatBytes:

#prologue 
    pushl %ebp 
    movl %esp, %ebp
    
    pushl %ebx
    
#body of the function

    movl $0, %eax
    movb byte1, %al
    movb byte2, %ah
    

    
#epilogue

    popl %ebx
    
    movl %ebp, %esp
    popl %ebp
    ret
