Interpreting the internal mechanism of pointer and reference through disassembly code

It is difficult to use natural languages such as Chinese and English to describe the similarities and differences between C ++ pointers and references in a concise and transparent manner, reading the disassembly code that contains pointers and references is a good way: this is definitely a non-ambiguity and concise statement as much as possible.For example, the following codeVoid main (void){Int x1 = 0, * ptrx1 = x1;Int x2 = 0, refx2 = x2; (* Ptrx1)

Disassembly Debug Dead Loop

In "C Traps and defects", the following code appears:#include The author's explanation is that if the compiler used to compile the program allocates memory to the variable in a way that decrements the memory address, the final assignment is to the variable I and into the dead loop.Run the program in VC6.0 to see the disassembly code:From the results, it is known that the allocation of memory results in decreasing the address of the variable to allocat

Disassembly tool usage

Kernel development, Kernel panic is more common. According to the exception stack, we can usually locate the approximate location of code errors, but sometimes we still need to use the Disassembly tool to help us locate some exceptions, objdump. This Disassembly tool exists in the prebuilts/GCC/linux-x86/ARM/gcc-linaro-aarch64-linux-gnu/bin/folder, you can refer to the following usage: 1) prebuilts/GCC/li

Examples of disassembly programs under Windows

After compiling the link, the program written under Windows can be debugged by debugging tools such as Debug, as well as the results of disassembly, which makes it easy to understand how the assembler instruction translates into "machine instructions". For Windows programs, there are a lot of tools like SoftICE, TRW, W32dasm, IDA, Hiew, and so on. Here to talk about W32dasm. ;===============================================================; Example: T

[C + + learning note] Disassembly angle see variable names and references as function arguments

1: value is passed by default when the variable name is used as a function parameterThe following points can be seen from the disassembly:1: Value passing by default (MOV)2: The transfer of parameters in a function call is passed from right to left 2: Passing parameters by reference is actually an address, not a variable The following points can be seen from the disassembly:The 1:lea takes the address operator, so the address is passed as a reference

Debug the C # program in Vs and view memory, registers, and disassembly.

When debugging a c # program in vs2005, you may want to view the assembly code, memory, and registers of the C # code. To view the disassembly code, right-click the code window and select "go to disassembly. In the assembly code window, you can follow F11 to execute code in a single step, so as to more accurately track code execution.

The advantage of method 1 is that byte code can be decompiled into code form, but after all, it is reverse engineering and sometimes some byte code will be inserted, I also encountered some files that were opened through disassembly and crash, but after all, there were a few. In addition, the disassembly
