register

Hi,

I'm currently getting started with NASM and wanted to know, how to output the contents of a register with NASM in Hexadecimal. I can output the content of eax with

section .bss
    reg_buf: resb 4
.
.
.
print_register:
    mov [reg_buf], eax
    mov eax, SYS_WRITE
    mov ebx, SYS_OUT
    mov ecx, reg_buf
    mov edx, 4
    int 80h
    ret

Let's say eax contains 0x44444444 then the output would be "DDDD". Apparently each pair of "44" is interpreted as 'D'. My ASCII table approves this.

But how do I get my program to output the actual register content (0x44444444)?

Square a number in NASM assembly without multiplication

Is it possible to square a number stored in a register (say eax) without doing any multiplication (by using shifts, etc)? I will be squaring a 16-bit number in 32-bit assembly so overflow shouldn't be an issue. I am using NASM x86 assembly to create the program. Thanks in advance for your help. >>> More
