/*C + + Compiler principle:1) first understand that declaration and definition are two different conceptsextern int i; Yes declaration, int i; Yes definitionThe function is much simpler.2) compilation is divided into:Precompiled: Replace macros, include, and other code to copy overCompiling: Turning code into a machine complaintLink: the. obj file is typically generated for each CPP file.

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.

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
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.
A simple example
