Embodiment 2

[0048] figure 2 It is a flow chart of a method for implementing a set lock provided in Embodiment 2 of the present invention. Such as figure 2 As shown, the method of this embodiment may include:

[0049] S210. When executing the compiler program added to the set of lock instructions, according to the switch parameters, send the corresponding execution instructions to the instruction buffer, where the set of lock instructions includes the execution instructions corresponding to the switch parameters.

[0050] In this embodiment, when the switch parameter indicates an on parameter or an off parameter, it corresponds to different execution instructions, that is, when the indications of the switch parameters are different, the execution instructions sent to the instruction buffer are also different.

[0051] S220, when the switch parameter is a parameter indicating to enable, analyze the compiler program through the corresponding execution instruction in the instruction buffe...

Abstract

The invention provides a toggle realization method and device; the method comprises the following steps: in execution of a compiler program with an added toggle order set, analyzing the compiler program according to switch parameters in the toggle order set; optimizing the compiler program according to the analysis result of the compiler program. The invention provides the toggle realization method suitable for a MIPS framework, thus solving the problems in the prior art that a toggle realization method based on an X86 framework is not suitable for the MIPS framework with a fixed length order; by using the novel toggle realization method and device, the development of the compiler program in the MIPS framework can be more convenient and effective.

Description

technical field [0001] The invention relates to computer technology, in particular to a method and device for realizing a set lock. Background technique [0002] In the development process of computer hardware and software, usually by adding a compiler to the client-side scripting language (JavaScript, referred to as: JS) engine of the browser, the purpose of accelerating the jump function of the browser is realized. [0003] Currently, detection and optimization of the compiler program are usually implemented by adding a toggle to the compiler program of the JS engine. For example, in the X86 architecture, the set lock function is realized by calling the call instruction and the nop instruction. Since the length of the instruction in the X86 architecture is variable, the function call instruction is 5 bytes as an example. One byte represents the call Instructions, such as calling the call instruction, the other 4 bytes represent the address of the called instruction. Howev...
