Is OC important work also done by the compiler ?, Oc compiler completed
NO, the important work of OC is done by the "runtime component" instead of the compiler. In fact, all data structures and functions required to use the object-oriented feature of OC are in runtime components.
For example:
The runtime component contains all memory management methods.

This large-scale C compiler is analyzed from a simple goal. After all, its functions are complex and the number of lines in the source program is also very large. Therefore, set a simple goal and then analyze it. Next, we will analyze its source program with the main line of compilation and running. Next, let's take a look at a simple C example, as follows: #001 # include
The metabase compiler is used to process C ++ extensions of QT. MoC analyzes the C ++ source file. If it finds that a header file contains the q_object macro definition, then, another c ++ source file is generated dynamically. The new source file contains the implementation of q_object.Code, The new C ++ source file will also be compiled,{tagshow(event)}">LinkTo the binary code of this class, because it is also a complete Part of this class. Generally

The brackets before the obviously called expression must have (pointer) function type compiler error C2064, compiler c2064
When I saw the phrase "the parentheses before the obviously called expression must have (pointer) function type", I found that my language level is poor and I cannot understand it at all, it took only half a day to know what went wrong.

"Type name digestion" refers to type digestion. The Type name is represented by the TypeRef object, and the Type is represented by the Type object. Type name resolution is to convert a TypeRef object to a Type object.

32-bitTherefore, the data stored on the disk does not need to change its structure and size, and shared data between remote or local processes (such as memory ing files) does not need to change its structure and size, this greatly reduces the programmer's work.Quantity.
To implement the same source codeRun in Win32 and run in win64. Defining the llp64 model is just the first step. Next, we need to define some pointer-related data types, such as the o
data type required for pointer calculation, the compiler determines whether the data type is 32-bit or 64-bit based on the target platform. These new data types are defined using the int and long types in C language, so they maintain backward compatibility with Win32 and some Windows API functions, microsoft plans to include these new data types in Beta 2 of Windows NT 5.0 and gradually port all Windows AP
Register allocation is a way to increase program execution speed by allocating program variables to registers as much as possible. Register is one of the most important problems in compiler optimization (good register allocation can increase program execution speed by more than 250%), and it is also one of the hottest research fields in compiler theory (the research field has proposed a large number of regi

This document describes how to use visual c ++ to create a Windows NT Service Program. Only one C ++ class is used to create the service. This class provides a simple interface between the service and the operating system. Using this class to impleme

Of all the features provided by the Win32 operating system, perhaps the most widely used but most lacking document description is structured exception handling (SEH), and when you consider Win32 structured exception handling, you may think of terms such as _try,_finally and _except. You can find a good description of SEH (even remedial) in any book about Win32. E

Microsoft Windows CE is a compact, efficient, and scalable operating system. It is widely used in a variety of embedded products, from handheld computers to specialized industrial controllers and consumer electronics. Windows CE has passed its own capabilities to prove that it can meet the needs of 32-bit embedded program development. Equally important: Windows CE enables embedded system designers to take full advantage of Microsoft's 32-bit Windows-based development tools.

Chapter 1Gcc
Section 1GccFamily Overview
GCC is a compiler originally used for programming in Unix-like systems. However, GCC also has many Win32 versions. Therefore, GCC may be a strange thing for many windows developers. Therefore, I hope that this chapter will give you a general understanding of GCC, a Windows developer.
History
GCC is a project of the GNU commun
++. It is the background C ++ compiler of Visual Studio, Visual Studio.net 2002, Visual Studio.net 2003, and Visual Studio.net 2005. With the introduction of Stanley Lippman and other compiler design Masters, it has become very mature and reliable. Visual C ++ 7.1 has 98.22% compatibility with standard C ++.
In the GCC family, gnu gcc is fundamental, and other compiler
