Note: this is x86 32 bit (not 64 bit)

1. What is the integer value in %eax?

movl $0x41000000, %eax

movl $0x420000, %ebx

movl $0x4300, %ecx

xor %ebx, %eax

xor %ecx, %eax

2. What will be printed to the screen?

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
