Hi, I want to learn asm, by follow the book 'Programming from the Ground Up'. But I failed on the first example~ .section .data .section .text .globl _start _start: movl $1, %eax movl $0, %ebx int $0x80 After as and ld, I only get Segmentation fault. I'm using Archlinux X86_64, binutils-2.21-4, with my custom kernel just to run 64bit code. Is there somethong wrong, or any book to learn x86_64 assemble? Thanks all!
