Http://blog.csdn.net/pendle/article/details/5958401 During inline processing of functionsProgramAn optimization method can reduce the overhead of calling a function. This method is applicable to a large number of small functions that are frequently called. Because the function content is copied to the place where each function is called, will increase the size of the compiled binary file. The specific process of inline processing is that during compilation, for a function that can be inline, t

time read and write memory from a certain 8 times times the address of the beginning, read out or write 8 bytes of data, if the software can guarantee that the double type of data from 8 times times the address of the beginning, then read or write a double type of data only need a memory operation. Otherwise, we might need two memory operations to complete this action, because the data might just be across two 8-byte blocks of memory that meet the alignment requirements. Some processors can mak

Do not use the IDE, directly using the compiler to process the source code, and then generate the corresponding EXE file, click to execute. The following is the use of C # compiler CSC.Configuration of the CSC compilerUse Notepad to write a C # program, save the extension to CS and store it in the D drive. This file will be a sample in this example. The code is to write "I love u" to the command line.Using

IntroductionThere is few information about what to compile boost with Intel compiler. This article are to describe a simple command steps to let you get a boost library with Intel compiler support.StepsStep 1:start your Intel compiler cmd window Start your Intel cmd window from "Start-and Intel Parallel Studio XXX--click the environment your need."

Label: style blog HTTP Io color ar OS sp This article mainly introduces how to compile thrift compiler in Windows + Visual Studio 2013, there are tutorials on thrift Official Website: http://thrift.apache.org/docs/BuildingFromSource, but some of the places in it are outdated, the provided flex and bison tool download links have also expired, so this article has made some preparations based on the original tutorial. Step 1: Use git to download thrift

Suppose we want to declare a variable of the vector type of STL, and read the information in the file:Std::ifstream in ("Data.txt");std::vectorAfter we reference the elements of data, we find that the compiler has an error. Why, let's analyze:At this point in the compiler, we are actually declaring a function, its return value is a vector, the parameter has two, the first parameter is a Istream_iterator obj

Summary of the implementation principles of polymorphism by the c ++ Compiler (1) Question: Define an empty type without any member variables or member functions. What is the result of sizeof operation on this type? The result is 1. Because an empty instance does not contain any information, the result is 0 after sizeof calculation, but when declaring an instance of any type, the memory must occupy a certain amount of space. Otherwise, these instance

HipHop is a PHP compiler project developed by Facebook. hipHop first converts PHP code into C ++ code, and then uses the C ++ compiler such as GCC to compile the target machine code. hipHop is used to improve the efficiency of Facebook servers. currently, over 90% of Facebook website traffic is processed by HipHop-compiled PHP code. hipHop also uses a series of PHP script code HipHop is a PHP

This article is reproduced in: http://www.cnblogs.com/liuxiaoming/archive/2012/08/13/2636831.html Some C compilers allow nested comments. Please write a test program that requires that the program can be compiled normally, whether it is a compiler that allows nested comments or a compiler that does not allow nested comments, however, in both cases, the program execution results are different. First, it sho

As a result of the work, the eclipse-developed Java project was copied and sometimes reported a strange mistake. Clearly the source is exactly the same, why the project copied to another machine, it will be reported "Java compiler level does not match the version of the installed Java project facet" error?：In fact, to solve is also very simple, under the Explorer, find the directory where the project, in the. Settings subdirectory, with a text editor

Differences in the compiler's implementation of the function pack extension for C + + 11 parameter templates (Variadic template)The topic is quite round the mouth. C + + 11 is not too much of a good thing, but the Variadic template is certainly one of the dazzling stars, in C + + design new thinking, you can see a lot of template code in order to support the number of indeterminate parameters, but to overload 1 parameters to n template parameters n functions. Although the type of code is general

When a user does not define a constructor for a class, the compiler does not have a default constructor for each class, and only synthesizes the default constructor when the compiler requires it. The compiler synthesizes the default constructors just to meet the compiler's needs, not to the programmer's needs (for example, the initialization of a member variable

A c language compiler for programming and Practice Compiling a compiler and learning the underlying programming method is a very effective way to learn how computers work. Compilers are often seen as very complex projects. In fact, writing a product-level compiler is indeed a huge task. But it is not that difficult to write a small and available

The C/C ++ compiler works by translating the source code to the target code that can be directly executed by a computer or virtual machine. However, the C/C ++ compiler is one of the earliest compilers, now let's study and research it. I hope you can get what you want. In the GCC family, gnu gcc is fundamental, and other compiler versions are exported from it. Am

C compiler profiling-managing the register for generating assembly code In a computer, the CPU speed is much faster than the memory speed. The compiler should make full use of register resources to reduce unnecessary access to the memory, this increases the speed of the compilation code generated by the compiler. In the intermediate code generation stage, the UCC

English Source: Sergey Matyukevich. Welcome to join the translation team. When you use a variable through an interface reference, do you know what the Go runtime does? The question is not easy to answer. This is because in Go, a type implements an interface, but this type does not contain any references to this interfa
