Abstract

The embodiment of the invention discloses a method, device and system for converging hotspot functions and variables in computer programs. The method for converging the hotspot functions in the computer programs includes the steps that source programs to be processed are acquired; the source programs are simulated and executed, calling information of each function in the source programs is collected when the source programs are executed to generate a critical path file, wherein the critical path file comprises one or more function critical paths when the source programs are executed; according to the critical path file, the hotspot functions, located in the same function critical path, in the source programs are compiled in the calling sequence and then linked into a same code segment, wherein the function critical paths are used for describing one or more hotspot functions and the calling sequence among the hotspot functions when the source programs are executed. According to the method, device and system, Cache Miss of instructions and Cache Miss of data can be effectively reduced.

Description

technical field [0001] The invention relates to computer technology, in particular to a method, device and system for gathering hotspot functions and variables in computer programs. Background technique [0002] In the process of computer program software development, programmers generally deploy function codes and variables in units of functional modules. After the source program is compiled and linked, the binary codes and global variables corresponding to the functions are also arranged according to their order in the source program file. Therefore, when the function and / or variable calls are adjacent or close, the access jump will not occur in the program execution, but when the function or global variable is called far away, the access jump will occur in the program execution, so that the processor in When accessing the cache, it is prone to more misses (Cache Miss). [0003] In order to reduce the Cache Miss phenomenon caused by access jumps during program execution, ...
