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

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

Java programs are initially interpreted by the interpreter, and when the virtual machine returns to a method or block of code run particularly frequently, the code will be mark
The MYC compiler uses a top-down approach for parsing syntax, which is usually done from the leftmost token, and then from top to bottom, which syntax rule may contain the token, and if it contains this token, it will match the following token from left to right according to the syntax rule. Top-down syntax parsing I'll explain in other articles that we've listed the syntax rules for MYC in the previous article:Program:: = (outer_decl | func_decl); OU
In the computer, the CPU speed is much faster than the memory speed, the compiler should make the best use of register resources, reduce unnecessary access to memory, thereby increasing the compiler generated by the assembly code run speed.

I always encourage CC ++ learners to first target the Console mode (DOS-like) program when they are new to this programming language. In other words, you don't want to write GUI programs, open windows, and have a dazzling screen at the beginning-it's just not going to fly first.

This section describes a series of common programming problems caused by the following two features of the C compiler.

First, as mentioned in the C ++ standard, a compilation unit [Translation Unit] refers to A. cpp file and all. H files it includesCodeWill be extended to include it. in the CPP file, and then the compiler compiles. CPP file is.

Hosts file.
During the compilation process, we found that the C ++ compiler is a very powerful C/C ++ compiler, which features high speed and high space efficiency, its version supports up to 92.73% Standard C ++ and greatly supports CPU optimization.
If you have two or a few C source files, you can easily use GCC to compile, connect, and generate executable files. For example, if you have two source files main. c and
