Description: This is Part 5 of the "Assembly Language Primer for Hackers" video series. Please begin here with Part 1, if you have not already done so. In this video we will go through an in-depth primer on data types which are used in assembly. We do a live demo on how to look at data in memory using GDB for .ascii, .int, .short, .float (.data) and .comm, .lcomm (.bss) types.Please download the VariableDemo.s code
Code:
# Demo program to show how to use Data types and MOVx instructions
.data
HelloWorld:
.ascii "Hello World!"
ByteLocation:
.byte 10
Int32:
.int 2
Int16:
.short 3
Float:
.float 10.23
IntegerArray:
.int 10,20,30,40,50
.bss
.comm LargeBuffer, 10000
.text
.globl _start
_start:
nop
# Exit syscall to exit the program
movl $1, %eax
movl $0, %ebx
int $0x80before you begin with the tutorial. Part 6 of the Assembly Language Primer for Hackers is available here. Enjoy!
