Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0026] see figure 1 As shown, the embodiment of the present invention provides a method for solving the multithreading problem caused by CPU optimization, including steps:

[0027] S1: setting a memory barrier in the program code, the memory barrier is used to sequentially execute all program codes before the memory barrier during CPU optimization to prevent code rearrangement;

[0028] S2: Perform CPU optimization on the program code.

[0029] By setting memory barriers and avoiding instruction rearrangement, it can effectively solve the problem of abnormal results caused by multi-threading caused by CPU optimization, which is safer and more reliable.

[0030] Among them, the memory barrier, also known as memory barrier, memory barrier or barrier instruction, is a kind of synchronization barrier instruction, which is a synchronization point...

Abstract

The invention discloses a method for solving a multi-thread problem caused by CPU optimization. The method relates to the field of internet application development, and comprises the following steps:setting a memory gate barrier in a program code, and then optimizing a CPU (Central Processing Unit), the memory gate barrier being used for sequentially executing all program codes before the memorygate barrier during CPU optimization to prevent code rearrangement. According to the method for solving the multi-thread problem caused by CPU optimization, the problem of result abnormity caused by multiple threads caused by CPU optimization can be effectively solved, and the method is safer and more reliable.

Description

technical field [0001] The invention relates to the field of Internet application development, in particular to a method and system for solving the multi-thread problem caused by CPU optimization. Background technique [0002] Usually a compiler is a program that translates "one language" into "another language". When writing program code in C++ language, it is usually necessary to use a C++ compiler to compile the C++ program code and convert it into the final Executable program. Moreover, C++ compilers generally have various compilation options, among which the optimization option is a commonly used compilation option. [0003] There are many compiler optimization options. Common compiler optimizations include: function embedding, useless code deletion, standardized loop structure, loop body unrolling, loop body merging, splitting, array filling, etc. Among them, the optimization of useless code deletion refers to the fact that the C++ compiler believes that some code lo...
