The invention provides a dynamic calling method and device for a function. The method comprises the following steps that: obtaining a packaging message, wherein the packaging message comprises an execution function, and the execution function comprises at least one parameter; according to a function calling appointment ABI (Application Binary Interface) way, storing the parameter; determining theaddress of the current execution position of the execution function; calling and executing a called function corresponding to the execution function, and determining the return value of the called function; and according to the address of the execution position, returning to the execution position of the execution function to continuously execute a program behind the execution position of the execution function, and storing a return value. When a compilation language which finishes being compiled is executed to effectively determine the parameter in the function, an operation of calling a context by the execution function is finished, and the execution and the calling of the function are finished.
Description
technical field [0001] The invention relates to computer processing technology, in particular to a method and device for dynamically calling a function. Background technique [0002] In computer programming, it is usually necessary to compile a high-level language into assembly language so that the computer executes the assembly language. [0003] However, in the prior art, in the process of compiling high-level language into assembly language, the parameters in the function of assembly language cannot be determined at that time, and it is necessary to determine the number of parameters in the function when the compiled assembly language is executed. number; at this time, the existing technology cannot execute the function whose number of parameters has not been determined, nor can it call the corresponding function. Contents of the invention [0004] The present invention provides a function dynamic call method and device, which are used to solve the problem in the prior...
