nasm assembly language tutorial

Recently, the company needs to complete security testing, resulting in the need for more in-depth study of attack methods and vulnerability analysis of the technology, the total feel a bit like a hacker:), but not only to know some of the security testing tools and tools to use, but also need basic Kung Fu, first from the University of the Assembly language (hehe, university lessons, For a long time did not

1. Development Tools In assembly languages, the tools used mainly use the following: Assembler, connector, debugger, Compiler Because I am here using ATT assembly language, the tools are also under gnu. 1.1 assembler () There are many assembler tools, such as masm, nasm, and gas. Unlike advanced languages, although th

) condition assemblyConditional assembly is to test the given conditions. Based on the test results, the assembler embeds a program into the source program or disassembles the program. The general format is as follows:If condition (expression)(Instruction body 1); condition is true assembly instruction body 1Else (Instruction body 2); condition: false assembly in

compiler's own function library, with-NOSTDLIB allows the compiler linker to select the function library that I write in my program.After you set up the stack in the assembly startup code, use the method (bl cfunction) to invoke the function cfunction in C language, such as the main function in the MCU (BL main). 5, the use of C language to access registers of t

for a code snippet. What is the purpose of this?In protected mode, the code snippet is not writable, so-called non-writable does not mean that the physical nature of the memory changed, so that the memory is not written, but that the code snippet descriptor access to the corresponding memory area, the processor does not allow to write data or change data.However, if you want to modify the code snippet, is there a way? Yes, that is to create a new descriptor for the code snippet, such as a reada
