Instruction installation method and device, electronic equipment and storage medium

Abstract

The embodiment of the invention provides an instruction installation method and device. The method comprises the following steps of: according to the comparison result of the maximum value of the fixed area of the processor and the buffer area size of the local instruction sequence stored in the virtual machine, allocating at least one fixed area as a buffer area from the memory address space, compiling the target jump instruction in the instruction sequence of the virtual machine into an area jump instruction in a local instruction sequence, installing a local instruction sequence into a target fixed area of the buffer area, controlling the distribution of the buffer area by taking the fixed area as a unit; compilation and installation of a local instruction sequence can be controlled. According to the method and the device, the skip instruction address and the skip target address of the regional skip instruction are ensured to be located in the same fixed region, so that the securityrisk caused by generating the regional skip instruction is avoided, the regional skip instruction is automatically compiled and generated, the quality of compiling and generating the skip instructionis further improved, and the execution performance of the skip instruction on the virtual machine is optimized.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to an instruction installation method, an instruction installation device, an electronic device and a readable storage medium. Background technique [0002] A virtual machine (VM, Virtual Machine) mainly uses software (or a small amount of hardware support) to virtualize a computer, and this virtual computer usually supports a set of corresponding instruction sets, called the virtual machine instruction set. . The virtual machine relies on the local physical machine (Host Machine), and simulates the execution of the given virtual machine instruction sequence (target program) on the local machine through its execution engine. [0003] The execution engine of the virtual machine can be implemented by an interpreter. Because interpreters have the characteristics of high portability, low implementation cost, and small memory footprint, the execution engines of most virtual machines ...
