movl $0x420000, %ebx

movl $0x4300, %ecx xor %ebx, %eax xor %ecx, %eax

1. What is the integer value in %eax? pushl %eax // move value of eax onto stack movl $0x04, %eax // syscall number for write into eax movl $0x01, %ebx // file descriptor for stdout into ebx movl %esp, %ecx // address of stack (what was in eax before) movl $0x04, %edx // number of bytes to write int $0x80 // syscall

// 2. What will be printed to the screen?
