Assembly language--call and RET directivesCall and RET instructionsBoth call and RET directives are transfer directives, both of which modify the IP, or both CS and IP.They are often used together to implement sub-program design.RET and RETFThe RET instruction uses the data in the stack to modify the contents of the IP so as to realize the near transfer.The RETF instruction uses the data in the stack to mod

code in memory:Execute the machine code in memory with the T command:Use the T command to continue execution:Use the a command to write machine instructions in memory:The above using the e command to write to the machine instructions, it is not very convenient, it is best to directly in the form of assembly instructions to write instructions, so the following a command appears:Write instructions to a memory unit starting with 1000:0 with a commandExp

A prominent advantage of computer assembly language is the use of symbols (symbol) to replace the target code, that is, a large number of binary code symbols to express, so that the assembly language source program easy to understand, easy to remember. In the Macro assembly

comparison.So 505 lines should insert a piece of code: pop ecx pop esi pop edi jmp.b;跳转到512行In fact, in these few lines of code, the Register ECX , the ESI EDI value inside is not important.Because in 514 rows, the ECX appropriate value is obtained;In the 512~513 line, the EDI appropriate value will be obtained;In 491 rows, the ESI appropriate value is obtained;So the above patch can be modified to: add esp,12 ;使栈平衡

Read Wang Shuang's "Assembly language second Edition" has been almost two months, the first few chapters written are some good understanding, so the speed slightly faster, to the middle, need to use the knowledge before the digestion, so some slightly slower. The middle section is the language core of the assembly, so

culture is, in another sense, equivalent to the common sense and intelligence of practitioners in the industry.Some people refer to computers as "electronic computers", as far as the source is concerned, computer is precisely this definition, because at that time the computer only has the ability to compute. However, after the advent of micro-computer (Micro Computer), its computational capacity has been replaced by a small calculator (Calculator), its main function is logical reasoning, graphi

Compare with Intel assembly language recently in the study of assembly language, the results appear very strange is, under the vc++6.0 code, the GCC compiler code is not the same, later found that Linux inherits the Unix family assembly instructions, usually common is the In

Today, let's use the specific instance code to use the usage of the tool mentioned yesterday. The main purpose of these examples is to familiarize yourself with the usage of assembly-related tools and the application of the assembly program template just mentioned yesterday. The tools we use mainly include as, ld, gcc, and gdb. Of course, they run in linux. Let's just give an example. Well, the following ex

The entry for the program is main, which calls the assembly function in main.The first thing to do is to solve the problem of defining functionsIn the C language, to extern a function declaration, and then this function in the assembly is implemented.In the Assembly, use export to introduce the function name defined in

6.828 of the tools have been installed, before the formal start of the experiment, you need to familiarize yourself with the use of each tool. For me this small white user, need to be familiar with more.1, x86 assembly languageSure enough, the course first made me familiar with assembly language, and provided two references. Although I am familiar with

to use memcpy multiple times (myMemcpy1 (XXX, myMemcpy1 (xx, XX, xx), XX), it must be returned. If not necessary and the original memcpy (), do not be too rigid (but it is recommended to return to RET, you can consider extending later).void* myMemcpy1 (void* dest, void* src, unsigned int n) { char* d = (char*) dest; char* s = (char*) src; char* ret = D; while (n--) { *d++ = *s++; } return ret; }Well, the implementation of all implemented, now to test under, of

The first basic concept of Win32 Assembler Win32 programs run in protected mode. In Windows, every Win32 application is put into a separate virtual address space to run. That is to say, each application has a 4 GB address space independent from each other, the operating system converts the 4 GB virtual address and physical memory address when the application is running, and divides the code into data in 16-bit windows, code and other segments have different memory modes. Win32 only has one memor

exposed to a hardware outage, unless you are using some special hardware, or require more stringent requirements, the most frequently modified hardware interrupts are interrupts (9H), especially text-editing programs. Generally speaking, Only the hardware designer base is a system programmer who notices all the hardware interrupts, and the designer who writes the memory-resident program uses only part of the hardware interrupts, especially the keyboard interrupts and the timer interrupt.
