Abstract

The invention provides a method and device for obtaining an actual address, a medium and electronic equipment. A first actual address of a first mark is obtained by setting the first mark in a first object code, and a second actual address of a first object sub-code in a memory is obtained by the sum of a first relative offset stored in a first configuration data set and the first actual address.According to the method for obtaining the actual address provided by the invention, the past consumed time is reduced from about 12ms to less than 1ms and is almost ignored. Therefore, the performanceof the system is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, in particular, to a method, device, medium and electronic equipment for obtaining a real address. Background technique [0002] Android (English full name Android) is a free and open source operating system based on Linux, mainly used in mobile terminals. [0003] From Android 4 to the current Android 10, each version will do a lot of performance and exception-related optimizations for virtual machines. And obtaining the actual address needs to update the memory information with read-only attribute. The characteristic of the memory information is that once it is stored in the memory, the application program can only read the memory information and cannot be changed or deleted. Therefore, it is difficult to upgrade the virtual machine after the Android terminal is listed. This leads to a large number of virtual machine problems in the terminals of the low-version Android system, whic...
